1 00:00:04,160 --> 00:00:07,160 Speaker 1: Get in touch with technology with tech stuff from how 2 00:00:07,240 --> 00:00:13,320 Speaker 1: stuff Works dot com, Hale and well met. This is 3 00:00:13,400 --> 00:00:16,840 Speaker 1: tech stuff and I am your host, Jonathan Strickland, senior 4 00:00:16,880 --> 00:00:19,720 Speaker 1: writer for how Stuff Works dot com. And many of 5 00:00:19,760 --> 00:00:23,120 Speaker 1: you know that in my life outside of the office, 6 00:00:23,880 --> 00:00:27,880 Speaker 1: I'm also the occasional Renaissance Festival performer. If you did 7 00:00:27,920 --> 00:00:31,120 Speaker 1: not know that, you know it now. I'm not ashamed 8 00:00:31,120 --> 00:00:35,440 Speaker 1: of this totally. I've actually even appeared as my Renaissance 9 00:00:35,440 --> 00:00:37,920 Speaker 1: Festival character on an episode of Stuff You Missed in 10 00:00:38,000 --> 00:00:40,600 Speaker 1: History Class. I'm not going to tell you the episode 11 00:00:40,600 --> 00:00:42,360 Speaker 1: title because I don't remember it off the top of 12 00:00:42,400 --> 00:00:45,000 Speaker 1: my head, but I do appear in it, so it's 13 00:00:45,000 --> 00:00:48,720 Speaker 1: a classic episode. I think might have been Sarah and 14 00:00:48,800 --> 00:00:52,720 Speaker 1: Dablina as the hosts back in those days. Anyway, I'm 15 00:00:52,760 --> 00:00:58,160 Speaker 1: performing at the Georgia Renaissance Festival this year season, and 16 00:00:58,640 --> 00:01:02,160 Speaker 1: the opening day for the Renaissance Festival is the day 17 00:01:02,200 --> 00:01:06,920 Speaker 1: after this podcast airs, so I thought, why not do 18 00:01:07,200 --> 00:01:11,160 Speaker 1: an episode inspired by ye olden times? And yes, I 19 00:01:11,200 --> 00:01:14,479 Speaker 1: know he is actually the We're going to go back 20 00:01:14,680 --> 00:01:17,600 Speaker 1: quite a bit before the Renaissance because today I'm going 21 00:01:17,640 --> 00:01:21,560 Speaker 1: to talk about siege engines. I thought it'd be kind 22 00:01:21,600 --> 00:01:24,720 Speaker 1: of fun and sort of in the theme of looking 23 00:01:24,760 --> 00:01:28,000 Speaker 1: back on history as I prepare to don my tights 24 00:01:28,000 --> 00:01:33,160 Speaker 1: and doublet I'm sorry for that mental image anyway. What 25 00:01:33,319 --> 00:01:35,560 Speaker 1: is a siege engine? While it's a device meant to 26 00:01:35,600 --> 00:01:39,920 Speaker 1: allow an attacking army to gain entry to a fortified space, 27 00:01:40,760 --> 00:01:44,279 Speaker 1: typically a fortified city or a castle, something along those lines, 28 00:01:44,319 --> 00:01:48,720 Speaker 1: they're they're used to penetrate or destroy fortress walls or gates, 29 00:01:48,800 --> 00:01:52,400 Speaker 1: and they tend to be enormous and they exert tremendous 30 00:01:52,560 --> 00:01:56,760 Speaker 1: force in their operation. I'm going to focus on siege 31 00:01:56,840 --> 00:01:59,840 Speaker 1: engines from ancient times to medieval history, but you should 32 00:02:00,040 --> 00:02:04,520 Speaker 1: know that siege engines continued to evolve even after medieval era, 33 00:02:05,560 --> 00:02:09,720 Speaker 1: even after the the invention of gunpowder and the distribution 34 00:02:09,760 --> 00:02:12,800 Speaker 1: of gunpowder. To be fair, gunpowder had been invented for 35 00:02:12,919 --> 00:02:16,519 Speaker 1: a very long time before anyone over in medieval Europe 36 00:02:16,520 --> 00:02:20,320 Speaker 1: figured out how to use it as a means for weaponry. 37 00:02:20,639 --> 00:02:24,280 Speaker 1: And uh also, gunpowder ended up making a lot of 38 00:02:24,320 --> 00:02:27,440 Speaker 1: the traditional city defenses ineffective. I'll talk about that more 39 00:02:27,600 --> 00:02:31,480 Speaker 1: later on in this episode, but siege engines were used 40 00:02:31,480 --> 00:02:35,160 Speaker 1: in both world wars. Actually, but I'm gonna save that 41 00:02:35,240 --> 00:02:37,120 Speaker 1: for a different episode. We're going to talk about the 42 00:02:37,200 --> 00:02:39,480 Speaker 1: old stuff, this kind of stuff you might see in 43 00:02:39,480 --> 00:02:42,959 Speaker 1: a movie about nights and royalty and stuff like that. 44 00:02:43,919 --> 00:02:48,880 Speaker 1: So siege weapons were necessary to penetrate a fortified position, typically, 45 00:02:48,919 --> 00:02:51,000 Speaker 1: like I said, a city or a castle. So why 46 00:02:51,000 --> 00:02:54,600 Speaker 1: would you lay siege to such a place at all. Essentially, 47 00:02:55,160 --> 00:02:57,640 Speaker 1: it's an effort to make the people inside surrender to 48 00:02:57,680 --> 00:03:00,800 Speaker 1: the people outside. It seems pretty simple. Usually the people 49 00:03:00,840 --> 00:03:04,160 Speaker 1: inside would include someone of importance who kind of had 50 00:03:04,160 --> 00:03:08,160 Speaker 1: the authority to hand over the rule of law for 51 00:03:08,240 --> 00:03:12,160 Speaker 1: that region to somebody else. And the word siege comes 52 00:03:12,200 --> 00:03:16,080 Speaker 1: from a Latin word sederre, which means to sit, And 53 00:03:16,120 --> 00:03:19,320 Speaker 1: that's pretty much what a sieging force does. It sits 54 00:03:19,360 --> 00:03:23,200 Speaker 1: outside a fortified area and it waits. It also usually 55 00:03:23,240 --> 00:03:25,720 Speaker 1: attempts to cut off supplies that are heading into the 56 00:03:25,760 --> 00:03:28,959 Speaker 1: fortified location, both food and water and other things, to 57 00:03:29,040 --> 00:03:32,120 Speaker 1: push the people inside to the point of desperation so 58 00:03:32,160 --> 00:03:36,560 Speaker 1: that they surrender. But sometimes a long wait just isn't convenient. 59 00:03:37,040 --> 00:03:40,200 Speaker 1: You've got places to go, people to meet, lands to conquer, 60 00:03:40,840 --> 00:03:43,760 Speaker 1: so you can't really wait around for people to eat 61 00:03:43,800 --> 00:03:48,200 Speaker 1: that last apple or to draw the last water from 62 00:03:48,240 --> 00:03:50,600 Speaker 1: the well. You've got to find a way to speed 63 00:03:50,640 --> 00:03:52,560 Speaker 1: things up a little bit. You've got to convince them 64 00:03:52,640 --> 00:03:56,960 Speaker 1: that they need to give up, and maybe force them 65 00:03:57,160 --> 00:03:59,880 Speaker 1: to give up, and that requires getting access to the 66 00:04:00,080 --> 00:04:06,840 Speaker 1: place that's fortified. Thus siege engines. Now, archaeologists have uncovered 67 00:04:06,880 --> 00:04:11,520 Speaker 1: evidence of fortified city walls from ancient cities all around 68 00:04:11,520 --> 00:04:13,240 Speaker 1: the world, and in a way, you could say that 69 00:04:13,320 --> 00:04:17,000 Speaker 1: human history is marked by innovations in ways to keep 70 00:04:17,040 --> 00:04:21,440 Speaker 1: a people safe and other innovations designed to overcome those protections. 71 00:04:22,520 --> 00:04:24,919 Speaker 1: It gets a pretty grim when you start thinking about 72 00:04:24,960 --> 00:04:28,200 Speaker 1: specifics and you get down to brass tacks, as it were. 73 00:04:28,240 --> 00:04:32,200 Speaker 1: But if ancient people had fortified walls, what did the 74 00:04:32,400 --> 00:04:37,919 Speaker 1: ancient attackers use to breach those walls. Well, there are 75 00:04:37,920 --> 00:04:40,440 Speaker 1: a couple of different tactics that don't involve siege engines 76 00:04:40,440 --> 00:04:42,719 Speaker 1: at all. For example, you might try and use fire 77 00:04:42,800 --> 00:04:47,080 Speaker 1: to weaken walls. You might tunnel under walls, either to 78 00:04:47,200 --> 00:04:51,039 Speaker 1: collapse the wall so that they just fall down, or 79 00:04:51,240 --> 00:04:54,479 Speaker 1: you end up just bypassing the wall entirely in tunnel 80 00:04:54,560 --> 00:04:56,479 Speaker 1: into the place that you're trying to get access to. 81 00:04:57,560 --> 00:04:59,880 Speaker 1: Or you might just use ladders to try and act 82 00:05:00,040 --> 00:05:02,680 Speaker 1: us the top of the wall and scale it. Obviously, 83 00:05:02,760 --> 00:05:04,840 Speaker 1: that could be dangerous if there are soldiers up at 84 00:05:04,839 --> 00:05:06,760 Speaker 1: the top of the wall to push the ladders down. 85 00:05:06,880 --> 00:05:10,000 Speaker 1: So you've got to hope that you can zerg rush 86 00:05:10,040 --> 00:05:12,960 Speaker 1: it use a whole bunch of people all at once. 87 00:05:13,680 --> 00:05:15,240 Speaker 1: If you don't know what a zer rushes, you need 88 00:05:15,279 --> 00:05:17,400 Speaker 1: to go listen to the tech Memes episode that published 89 00:05:17,400 --> 00:05:22,080 Speaker 1: not too long ago. So the ancients would start to 90 00:05:22,080 --> 00:05:25,159 Speaker 1: construct massive tools to break through barriers. These are the 91 00:05:25,200 --> 00:05:29,719 Speaker 1: siege engines. They're bigger than things like just a tunnel 92 00:05:29,920 --> 00:05:34,840 Speaker 1: or a ladder, and arguably the oldest version of the 93 00:05:34,880 --> 00:05:38,840 Speaker 1: siege engine is the battering ram. So I'm sure you're 94 00:05:38,880 --> 00:05:42,320 Speaker 1: all familiar with the concept, but just in case. A 95 00:05:42,320 --> 00:05:46,120 Speaker 1: battering ram is a large mass that can be swung 96 00:05:46,279 --> 00:05:49,800 Speaker 1: so that it has its impact against a surface and 97 00:05:49,880 --> 00:05:54,239 Speaker 1: that causes that surface to become damaged. In other words, 98 00:05:54,240 --> 00:05:57,680 Speaker 1: it's like an enormous hammer breaking through a wall or 99 00:05:57,720 --> 00:06:01,440 Speaker 1: a door, and an example could be just an enormous log. 100 00:06:02,440 --> 00:06:05,960 Speaker 1: And the earliest battering rams were held by people, but 101 00:06:06,040 --> 00:06:09,880 Speaker 1: that was problematic. People can only hold weight up to 102 00:06:09,920 --> 00:06:12,120 Speaker 1: a certain limit, and then it's just too heavy to move, 103 00:06:12,839 --> 00:06:16,280 Speaker 1: it slows them down and they remain unprotected and can 104 00:06:16,320 --> 00:06:19,279 Speaker 1: be picked off by archers or people with slings or 105 00:06:19,320 --> 00:06:24,560 Speaker 1: other projectiles. So you want to improve upon this idea. 106 00:06:24,760 --> 00:06:27,440 Speaker 1: So another example would be a log that is hung 107 00:06:27,600 --> 00:06:31,560 Speaker 1: from a wooden frame by various ropes, and the ropes 108 00:06:31,600 --> 00:06:34,360 Speaker 1: allow the log to swing horizontally so that the end 109 00:06:34,560 --> 00:06:37,400 Speaker 1: can crash into that vertical surface like a wall or 110 00:06:37,440 --> 00:06:40,800 Speaker 1: a gate. Uh. This would allow you to have a 111 00:06:40,880 --> 00:06:43,560 Speaker 1: much heavier battering ram than something you would have to 112 00:06:43,600 --> 00:06:46,000 Speaker 1: carry by hand, because you could put it on this 113 00:06:46,360 --> 00:06:49,560 Speaker 1: rope system and just swing it and as opposed to 114 00:06:49,600 --> 00:06:54,640 Speaker 1: having to lift it. According to ancient historians, the earliest 115 00:06:54,640 --> 00:06:58,279 Speaker 1: example of this technology was the brainchild of a certain 116 00:06:59,200 --> 00:07:04,080 Speaker 1: pe frasm No of Tire, and I apologize for absolutely 117 00:07:04,279 --> 00:07:07,520 Speaker 1: butchering the pronunciation of that name, because I'm certain I 118 00:07:07,560 --> 00:07:11,600 Speaker 1: did anyway. This particular engineer would have lived sometime between 119 00:07:11,680 --> 00:07:15,520 Speaker 1: five hundred and three fifty b C. And his His 120 00:07:15,840 --> 00:07:19,480 Speaker 1: main invention was suspending a cross beam from a transverse 121 00:07:19,520 --> 00:07:22,120 Speaker 1: beam for the purposes of swinging it as a battering ram. 122 00:07:22,160 --> 00:07:24,960 Speaker 1: In other words, that design I was talking about hanging 123 00:07:25,160 --> 00:07:29,640 Speaker 1: a wooden beam in a frame so that you can 124 00:07:29,880 --> 00:07:34,040 Speaker 1: bash down a wall or a door. Now, typically you 125 00:07:34,080 --> 00:07:37,760 Speaker 1: would also find that the frames holding these battering rams 126 00:07:37,760 --> 00:07:41,520 Speaker 1: would be shielded by a roof, and often that roof 127 00:07:41,560 --> 00:07:46,280 Speaker 1: would be covered with dampened animal skins. That would help 128 00:07:46,320 --> 00:07:50,240 Speaker 1: cut down on the potential for fire. If you're defending 129 00:07:50,280 --> 00:07:54,120 Speaker 1: city was using flaming arrows or burning oil or something 130 00:07:54,160 --> 00:07:57,680 Speaker 1: on those lines, it would it would reduce the possibility 131 00:07:57,760 --> 00:08:00,840 Speaker 1: that your brand new, shiny battering ram would just become 132 00:08:00,960 --> 00:08:06,520 Speaker 1: kindling and uh. You would also protect yourself from other 133 00:08:06,600 --> 00:08:09,880 Speaker 1: just basic projectiles and allow the operators of the battering 134 00:08:09,920 --> 00:08:16,600 Speaker 1: battering ram to continue hammering against the wall or the door. Obviously, 135 00:08:17,240 --> 00:08:19,880 Speaker 1: this was risky. You had to get access to the 136 00:08:19,920 --> 00:08:24,880 Speaker 1: actual wall and according to Vitruvius, who was an author 137 00:08:24,960 --> 00:08:28,560 Speaker 1: and engineer during the first century, the first person to 138 00:08:28,600 --> 00:08:34,760 Speaker 1: create a fireproofed roofed battering ram was Kros the Carthaginian 139 00:08:35,840 --> 00:08:40,439 Speaker 1: sometimes called Garross with a G the Carthaginian. Modern historians 140 00:08:40,480 --> 00:08:43,800 Speaker 1: believe this person was alive sometime around the fifth century 141 00:08:43,880 --> 00:08:48,160 Speaker 1: b C. And this was after the Iron Age that 142 00:08:48,240 --> 00:08:53,680 Speaker 1: had happened several hundred years earlier, so it was very 143 00:08:53,720 --> 00:08:59,000 Speaker 1: common for the attacking party to cap a battering ram 144 00:08:59,040 --> 00:09:04,559 Speaker 1: with a large iron or otherwise metal cap, often shaped 145 00:09:04,640 --> 00:09:09,240 Speaker 1: in the form of a battering ram like a literal ram, 146 00:09:09,800 --> 00:09:14,000 Speaker 1: like a goat's head with horns. Uh. The iron would 147 00:09:14,000 --> 00:09:17,320 Speaker 1: give the battering ram even more weight and resilience, and 148 00:09:17,320 --> 00:09:21,200 Speaker 1: it would make it more effective. The animals would and 149 00:09:21,280 --> 00:09:23,920 Speaker 1: you know it forms made it look more interesting. But 150 00:09:23,960 --> 00:09:28,000 Speaker 1: they also could help with bashing through the the material, 151 00:09:28,160 --> 00:09:32,680 Speaker 1: depending upon the shapes you were using, and uh, yeah, 152 00:09:32,679 --> 00:09:36,400 Speaker 1: it was a pretty effective means of knocking down your 153 00:09:36,440 --> 00:09:39,960 Speaker 1: basic city walls. Uh. They You also would see other 154 00:09:40,000 --> 00:09:43,000 Speaker 1: improvements like pulley systems that would allow the battering ram 155 00:09:43,040 --> 00:09:46,400 Speaker 1: to remain horizontal as it swung instead of tilting upward. 156 00:09:46,840 --> 00:09:49,439 Speaker 1: So imagine a swing set swing. You know, when you're 157 00:09:49,440 --> 00:09:51,920 Speaker 1: swinging on a swing, your feet tilt up in the 158 00:09:51,920 --> 00:09:55,320 Speaker 1: air instead of staying horizontal unless you're actively moving your 159 00:09:55,400 --> 00:09:59,600 Speaker 1: legs down. And uh, the pulley system would counteract that 160 00:10:00,040 --> 00:10:04,440 Speaker 1: dency so that way you wouldn't be hitting the wall 161 00:10:04,679 --> 00:10:08,199 Speaker 1: or door on an upward swing. It would be translated 162 00:10:08,200 --> 00:10:11,880 Speaker 1: into a horizontal motion so that that momentum that you're 163 00:10:11,880 --> 00:10:15,200 Speaker 1: transferring would be in the proper direction. And that's what 164 00:10:15,240 --> 00:10:18,479 Speaker 1: we're talking about. The working principle behind the battering ram 165 00:10:18,600 --> 00:10:24,240 Speaker 1: is the transfer of momentum momentum quick recap for people 166 00:10:24,240 --> 00:10:27,679 Speaker 1: who don't remember their physics. It's the quantity of motion 167 00:10:27,760 --> 00:10:30,800 Speaker 1: and a moving body. And the way you arrive at 168 00:10:31,400 --> 00:10:36,120 Speaker 1: the quantity of momentum is by multiplying the mass of 169 00:10:36,160 --> 00:10:41,040 Speaker 1: a moving body by its velocity, So that means momentum 170 00:10:41,080 --> 00:10:44,160 Speaker 1: of a small object that's moving very very very fast 171 00:10:44,559 --> 00:10:47,000 Speaker 1: can be the same as a large object moving much 172 00:10:47,040 --> 00:10:50,640 Speaker 1: more slowly if the numbers work out the right way. 173 00:10:50,679 --> 00:10:52,960 Speaker 1: But if something is really big and really fast, it 174 00:10:53,000 --> 00:10:56,000 Speaker 1: has a whole lot of momentum to it. And I've 175 00:10:56,000 --> 00:10:59,000 Speaker 1: got some funny stories about momentum. I had to explain 176 00:10:59,080 --> 00:11:02,760 Speaker 1: this to a friend of mine. Uh. At the Renaissance Festival, 177 00:11:03,320 --> 00:11:09,040 Speaker 1: there was a moment in a dance dance in which 178 00:11:09,160 --> 00:11:13,520 Speaker 1: it is possible to steal the partner of another person um, 179 00:11:13,559 --> 00:11:15,880 Speaker 1: in which I was trying to steal the queen from 180 00:11:15,880 --> 00:11:18,920 Speaker 1: the king. The king being played by a guy who 181 00:11:18,920 --> 00:11:22,680 Speaker 1: looked an awful lot like Henry the Eighth, including Henry 182 00:11:22,720 --> 00:11:27,280 Speaker 1: the Eighth impressive mass, and this fellow collided with me. 183 00:11:27,360 --> 00:11:29,520 Speaker 1: He gave me a little hip check, and he wasn't 184 00:11:29,520 --> 00:11:33,240 Speaker 1: moving fast, but he did outweigh me by a significant amount, 185 00:11:33,480 --> 00:11:36,800 Speaker 1: and so I went flying, and thus the transfer of 186 00:11:36,880 --> 00:11:42,600 Speaker 1: momentum was demonstrated in a very real and ultimately painful way. 187 00:11:43,240 --> 00:11:45,920 Speaker 1: I have since forgiven him. It actually was pretty funny, 188 00:11:46,000 --> 00:11:48,240 Speaker 1: but I did sprain both my wrists and my ankle 189 00:11:48,280 --> 00:11:52,560 Speaker 1: in that incident. So with battering rams, your desired outcome 190 00:11:52,640 --> 00:11:55,160 Speaker 1: is to have a very large mass, and you wanted 191 00:11:55,240 --> 00:11:58,000 Speaker 1: to move really quickly so that you can result in 192 00:11:58,080 --> 00:12:01,520 Speaker 1: this large amount of momentum that transfer to a stationary 193 00:12:01,520 --> 00:12:05,000 Speaker 1: object like the wall or the gate, and thus caused 194 00:12:05,040 --> 00:12:08,760 Speaker 1: damage to it. So once battering ram started getting better, 195 00:12:08,800 --> 00:12:13,240 Speaker 1: obviously cities needed to respond, and they began to reinforce 196 00:12:13,320 --> 00:12:16,880 Speaker 1: their walls, making them thicker at the base and trying 197 00:12:16,920 --> 00:12:21,560 Speaker 1: to create new strategies to repel battering ram assaults. My 198 00:12:21,640 --> 00:12:25,840 Speaker 1: favorite battering ram is actually a fictional one. I like 199 00:12:26,000 --> 00:12:30,440 Speaker 1: grond Grand was the battering Ram and Lord of the Rings. 200 00:12:30,480 --> 00:12:33,240 Speaker 1: It was from Suron's army. They used it in the 201 00:12:33,320 --> 00:12:37,400 Speaker 1: siegeen mins Tira, and it was ont long and had 202 00:12:37,400 --> 00:12:40,280 Speaker 1: a metal cap that was shaped like a wolf. And 203 00:12:40,280 --> 00:12:42,600 Speaker 1: the most of the depictions I've seen the wolf is 204 00:12:42,640 --> 00:12:47,120 Speaker 1: also got some sort of fire or lava coming out 205 00:12:47,120 --> 00:12:52,720 Speaker 1: of its mouth, making it pretty intimidating. Awesome image. Really. 206 00:12:53,880 --> 00:12:56,959 Speaker 1: Another ancient season gen similar to this in the sense 207 00:12:57,040 --> 00:12:59,840 Speaker 1: that you had to get super close to your target 208 00:13:00,400 --> 00:13:04,200 Speaker 1: was the siege tower. This is a pretty simple concept. 209 00:13:04,400 --> 00:13:08,680 Speaker 1: It's usually it's like a tower that's on wheels, and 210 00:13:08,800 --> 00:13:12,160 Speaker 1: you push this tower up against the city wall that 211 00:13:12,280 --> 00:13:16,200 Speaker 1: you want to uh you want to get past, and 212 00:13:16,559 --> 00:13:19,120 Speaker 1: you have a gang plank at the top of the 213 00:13:19,160 --> 00:13:22,760 Speaker 1: tower that you lower so that it rests on the 214 00:13:22,800 --> 00:13:26,559 Speaker 1: city wall, and then your your force just goes through 215 00:13:26,679 --> 00:13:31,120 Speaker 1: the siege tower, across the gang plank and into the city. 216 00:13:31,320 --> 00:13:37,439 Speaker 1: Then you bipass the wall. Entirely very basic idea. Uh. Obviously, 217 00:13:37,760 --> 00:13:40,280 Speaker 1: things could go wrong. The tower if it were set 218 00:13:40,320 --> 00:13:43,240 Speaker 1: on fire, could end up causing you to lose quite 219 00:13:43,240 --> 00:13:46,959 Speaker 1: a few of your men. Uh. And also there are 220 00:13:47,280 --> 00:13:50,440 Speaker 1: lots of different ways to create obstacles to make it 221 00:13:50,480 --> 00:13:53,520 Speaker 1: more difficult to get the tower up against a city wall. 222 00:13:54,320 --> 00:13:58,800 Speaker 1: One of those would be moats. So your basic moat 223 00:13:58,960 --> 00:14:03,080 Speaker 1: around a castle was really a defense against siege engines 224 00:14:03,160 --> 00:14:05,840 Speaker 1: like this. Uh. It meant that it was much harder 225 00:14:05,880 --> 00:14:09,080 Speaker 1: to get something like a siege tower up against the 226 00:14:09,080 --> 00:14:11,800 Speaker 1: castle walls, because he had to get across the moat first, 227 00:14:11,880 --> 00:14:14,320 Speaker 1: and the moat might either be dry or it could 228 00:14:14,320 --> 00:14:17,960 Speaker 1: be filled with water. Not all moats were water. In fact, 229 00:14:18,000 --> 00:14:19,920 Speaker 1: most of them weren't. Most of them were essentially just 230 00:14:19,960 --> 00:14:25,280 Speaker 1: a very big ditch around the fort fortified area, so 231 00:14:25,360 --> 00:14:26,840 Speaker 1: you would have to find a way to bridge that 232 00:14:26,880 --> 00:14:29,520 Speaker 1: gap if you were an attacker, to allow your siege 233 00:14:29,520 --> 00:14:31,840 Speaker 1: engine to roll over the moats, you had to build 234 00:14:31,920 --> 00:14:35,560 Speaker 1: like essentially a temporary bridge to allow the siege engine 235 00:14:35,600 --> 00:14:38,520 Speaker 1: to roll over it and get access to the city wall. 236 00:14:38,840 --> 00:14:41,880 Speaker 1: And another defense was to redesign city walls in the 237 00:14:41,920 --> 00:14:44,480 Speaker 1: first place. Engineers began to make walls that were very 238 00:14:44,480 --> 00:14:47,280 Speaker 1: thick at the base and would slope from the top 239 00:14:47,440 --> 00:14:50,800 Speaker 1: down to the base, and that slope meant that the 240 00:14:50,880 --> 00:14:53,680 Speaker 1: top of the wall would be further away from a 241 00:14:53,720 --> 00:14:56,720 Speaker 1: tower than the base of the wall. You know, it's 242 00:14:56,800 --> 00:15:01,720 Speaker 1: because it sloped away from the out side. So that 243 00:15:01,760 --> 00:15:04,120 Speaker 1: meant that your gang plank had to be longer in 244 00:15:04,240 --> 00:15:07,400 Speaker 1: order to reach from the siege tower to the top 245 00:15:07,440 --> 00:15:10,760 Speaker 1: of the city wall. And gang planks were really the 246 00:15:10,800 --> 00:15:15,040 Speaker 1: weak points of the siege towers. Assuming that you've major 247 00:15:15,080 --> 00:15:17,600 Speaker 1: siege tower as fireproof as you can manage, which again 248 00:15:17,720 --> 00:15:21,640 Speaker 1: mostly involved putting the hides of animals on the outside 249 00:15:21,640 --> 00:15:24,360 Speaker 1: of the tower and wetting them down, you know, drenching 250 00:15:24,400 --> 00:15:28,240 Speaker 1: them in water as as much as you possibly can. Then, 251 00:15:28,480 --> 00:15:30,760 Speaker 1: once you set down the gang plank and you have 252 00:15:30,800 --> 00:15:34,520 Speaker 1: attackers going across, their most vulnerable when they are on 253 00:15:34,680 --> 00:15:39,040 Speaker 1: that gang plank there standing over the height of the wall. 254 00:15:39,440 --> 00:15:42,640 Speaker 1: There's probably a moat below them. The gang planks probably 255 00:15:42,680 --> 00:15:48,440 Speaker 1: not incredibly sturdy or or stable. So the further away 256 00:15:48,840 --> 00:15:51,160 Speaker 1: the top of the siege tower is from the top 257 00:15:51,160 --> 00:15:54,000 Speaker 1: of the wall, the harder it is for the attackers 258 00:15:54,000 --> 00:15:57,160 Speaker 1: to get over. So that was just a basic defense mechanism, 259 00:15:57,240 --> 00:16:00,640 Speaker 1: was to build these sloping walls for cities to help 260 00:16:00,800 --> 00:16:05,520 Speaker 1: protect against siege engines. Now, both siege towers and battering 261 00:16:05,600 --> 00:16:09,160 Speaker 1: rams were made obsolete by the invention of cannons later on. 262 00:16:09,240 --> 00:16:11,440 Speaker 1: I'll talk about cannons towards the end of this episode. 263 00:16:11,600 --> 00:16:14,240 Speaker 1: Cannon's actually made those high city walls obsolete. In the 264 00:16:14,280 --> 00:16:17,400 Speaker 1: first place. Higher walls were more vulnerable to cannon fire, 265 00:16:17,640 --> 00:16:20,880 Speaker 1: and so the design of city fortifications had to completely change. 266 00:16:21,040 --> 00:16:26,280 Speaker 1: Once those became a major element in warfare. At that point, 267 00:16:26,320 --> 00:16:28,920 Speaker 1: those siege engines began to fade into history. You didn't 268 00:16:28,960 --> 00:16:32,000 Speaker 1: really see them anymore. But I'll get more into cannons 269 00:16:32,000 --> 00:16:34,440 Speaker 1: a little bit later in the episode. And I'm sure 270 00:16:34,520 --> 00:16:38,080 Speaker 1: you've already noted that the major disadvantage to both battering 271 00:16:38,200 --> 00:16:40,240 Speaker 1: rams and siege towers is that you have to get 272 00:16:40,240 --> 00:16:42,440 Speaker 1: close to your target for them to work. If the 273 00:16:42,480 --> 00:16:45,840 Speaker 1: defending city has set up other defenses like those trenches 274 00:16:45,960 --> 00:16:49,160 Speaker 1: or pits or spikes, and they have stuff like hot 275 00:16:49,200 --> 00:16:53,360 Speaker 1: oil or flaming weapons, getting close isn't terribly attractive. You 276 00:16:53,360 --> 00:16:56,520 Speaker 1: would much prefer to batter the city from a distance, 277 00:16:56,520 --> 00:17:00,240 Speaker 1: and so attackers began to design new engines, things that 278 00:17:00,280 --> 00:17:03,200 Speaker 1: could allow attacks from much further away. So next I'll 279 00:17:03,240 --> 00:17:06,639 Speaker 1: talk about some of the massive projectile weapons that were used. 280 00:17:07,200 --> 00:17:11,080 Speaker 1: Uh and they relied purely on mechanical physics to hurl 281 00:17:11,240 --> 00:17:14,320 Speaker 1: objects at walls. They're pretty cool. Before I do that, 282 00:17:14,640 --> 00:17:25,560 Speaker 1: let's take a quick break to thank our sponsor. So 283 00:17:25,600 --> 00:17:27,840 Speaker 1: the first projectile siege engine I really want to talk 284 00:17:27,840 --> 00:17:31,040 Speaker 1: about is the ballista. And if you were to take 285 00:17:31,040 --> 00:17:33,400 Speaker 1: a casual glance at a ballista, you might think it's 286 00:17:33,440 --> 00:17:37,760 Speaker 1: an enormous crossbow, and it does resemble a crossbow. But 287 00:17:37,840 --> 00:17:41,840 Speaker 1: they crossbow and the ballista work on two different principles, 288 00:17:41,960 --> 00:17:46,040 Speaker 1: two different two different types of tension. Uh, the operation 289 00:17:46,080 --> 00:17:49,840 Speaker 1: of the ballista depends upon two torsion springs, whereas the 290 00:17:49,880 --> 00:17:55,359 Speaker 1: crossbow depends upon the natural tension of the bow itself. 291 00:17:56,800 --> 00:18:00,800 Speaker 1: So let's talk about torsion springs. Torsion springs work by twisting. 292 00:18:00,840 --> 00:18:05,159 Speaker 1: They store mechanical energy when you twist the torsion spring, 293 00:18:05,600 --> 00:18:09,280 Speaker 1: and when you release the spring, it unleashes that mechanical 294 00:18:09,359 --> 00:18:13,199 Speaker 1: energy through untwisting, so it's winding and unwinding. When you 295 00:18:13,240 --> 00:18:15,920 Speaker 1: wind it up, you've got the mechanical energy, and when 296 00:18:15,960 --> 00:18:19,159 Speaker 1: you let it go, it unwinds itself and releases that 297 00:18:19,240 --> 00:18:22,840 Speaker 1: mechanical energy. To make a ballista, you need a pair 298 00:18:23,240 --> 00:18:26,000 Speaker 1: of torsion springs that you can twist tightly so that 299 00:18:26,040 --> 00:18:29,159 Speaker 1: when you release them, they unleash that mechanical force in 300 00:18:29,200 --> 00:18:31,760 Speaker 1: such a way as to throw a projectile, typically a 301 00:18:31,880 --> 00:18:35,720 Speaker 1: large dart with an iron tip at a target. Now, 302 00:18:37,880 --> 00:18:41,480 Speaker 1: in ancient times, a torsion spring might look like a 303 00:18:41,560 --> 00:18:45,959 Speaker 1: loop of some stretchy elastic material. That material was often 304 00:18:46,800 --> 00:18:51,439 Speaker 1: either hair from animals sometimes humans, all woven together to 305 00:18:51,480 --> 00:18:55,280 Speaker 1: make really strong ropes, or sometimes it was ligaments and 306 00:18:55,600 --> 00:18:58,520 Speaker 1: other tissue that was turned into this kind of elastic 307 00:18:58,600 --> 00:19:02,399 Speaker 1: material and then looped around a frame like a skein 308 00:19:02,680 --> 00:19:05,880 Speaker 1: that's inside a frame. So imagine a loop of material. 309 00:19:05,920 --> 00:19:09,439 Speaker 1: In fact, just imagine a rubber band, and imagine that 310 00:19:09,520 --> 00:19:13,399 Speaker 1: you've got two pegs that are a few inches apart 311 00:19:13,400 --> 00:19:16,560 Speaker 1: from each other. They're further apart than the length of 312 00:19:16,640 --> 00:19:19,200 Speaker 1: the rubber band, so you have to stretch the rubber 313 00:19:19,200 --> 00:19:23,280 Speaker 1: band a little bit two loop either end over the 314 00:19:23,320 --> 00:19:26,600 Speaker 1: two pegs. Then you put more rubber bands that are 315 00:19:26,640 --> 00:19:29,480 Speaker 1: the same length over those two pegs, so you've got 316 00:19:29,640 --> 00:19:33,119 Speaker 1: a few of them, maybe four or five. These rubber 317 00:19:33,160 --> 00:19:38,680 Speaker 1: bands represent an unwound torsion spring. If you then inserted 318 00:19:39,320 --> 00:19:44,080 Speaker 1: a throwing arm, what would be considered like the shaft 319 00:19:44,160 --> 00:19:48,680 Speaker 1: of a throwing arm, into that gap the middle of 320 00:19:48,720 --> 00:19:53,320 Speaker 1: all those rubber bands, and then use it to twist 321 00:19:53,440 --> 00:19:58,040 Speaker 1: the rubber bands in a circle, either clockwise or counterclockwise. 322 00:19:58,600 --> 00:20:03,320 Speaker 1: You would create the hortion. This this twisted tension. You 323 00:20:03,400 --> 00:20:05,520 Speaker 1: look them over and over again. You can do this 324 00:20:05,560 --> 00:20:09,120 Speaker 1: with a pencil. So again, just have a rubber band. 325 00:20:09,119 --> 00:20:11,520 Speaker 1: You can even have maybe someone stand in front of 326 00:20:11,560 --> 00:20:14,040 Speaker 1: you putting their two thumbs up, and you loop the 327 00:20:14,160 --> 00:20:16,920 Speaker 1: rubber bands around their two thumbs so that they're stretching 328 00:20:16,960 --> 00:20:20,399 Speaker 1: them together. You put a pencil in there. You twist 329 00:20:20,480 --> 00:20:23,080 Speaker 1: the pencil around a few times so that it's it's 330 00:20:23,080 --> 00:20:26,760 Speaker 1: twisting the rubber bands, and you'll start building up that tension. 331 00:20:27,040 --> 00:20:29,880 Speaker 1: If you let go of the pencil, then it will 332 00:20:30,000 --> 00:20:32,720 Speaker 1: unleash all that mechanical energy and it will make the 333 00:20:32,720 --> 00:20:35,800 Speaker 1: pencil flip around like crazy. Make sure you use an 334 00:20:35,840 --> 00:20:39,000 Speaker 1: unsharpened pencil and be very careful with this sort of 335 00:20:39,000 --> 00:20:40,600 Speaker 1: stuff because it might fly up and hit you in 336 00:20:40,640 --> 00:20:45,480 Speaker 1: the face. But this is the basic principle of the ballista. Now, 337 00:20:45,480 --> 00:20:49,080 Speaker 1: with the ballista, you have two of these torsion springs, 338 00:20:49,720 --> 00:20:55,160 Speaker 1: and that meant that they're actually vertically aligned, not horizontally aligned. 339 00:20:55,960 --> 00:20:58,440 Speaker 1: In other words, you would have imagine you have one 340 00:20:58,520 --> 00:21:02,120 Speaker 1: thumb higher the the other thumb directly in front of you, 341 00:21:02,359 --> 00:21:05,000 Speaker 1: and you put the rubber bands on so that you 342 00:21:05,080 --> 00:21:07,600 Speaker 1: were holding the loop that way. That's the way the 343 00:21:07,640 --> 00:21:11,760 Speaker 1: ballista torsion springs are aligned. You have to have those 344 00:21:11,840 --> 00:21:15,760 Speaker 1: that vertical alignment and they're parallel to each other, and 345 00:21:15,840 --> 00:21:19,920 Speaker 1: between the two torsion springs you have your stock or channel. 346 00:21:20,240 --> 00:21:24,000 Speaker 1: That's where the projectile moves through. So with a crossbow, 347 00:21:24,080 --> 00:21:27,920 Speaker 1: this would be where the bolt would slide through as 348 00:21:27,960 --> 00:21:30,680 Speaker 1: it's being launched from the crossbow. Same sort of thing 349 00:21:30,680 --> 00:21:33,439 Speaker 1: with a ballista. It's got that stock with the channel 350 00:21:33,440 --> 00:21:36,399 Speaker 1: in it. That's where the projectile moves through it, and 351 00:21:36,440 --> 00:21:40,640 Speaker 1: it's between these two vertically aligned torsion springs. So you've 352 00:21:40,680 --> 00:21:45,480 Speaker 1: got your enormous dart loaded into your ballista, and you've 353 00:21:45,520 --> 00:21:49,679 Speaker 1: got your two vertically aligned torsion springs. In each torsion spring, 354 00:21:49,840 --> 00:21:54,880 Speaker 1: you have a throwing arm. Now, the torsion spring on 355 00:21:54,920 --> 00:21:59,520 Speaker 1: the left side is wound counter clockwise if you were 356 00:21:59,560 --> 00:22:02,639 Speaker 1: looking at it from above. That means that when the 357 00:22:02,680 --> 00:22:05,840 Speaker 1: tension releases, it's going to spend its throwing arm in 358 00:22:05,880 --> 00:22:10,680 Speaker 1: a clockwise direction. The torsion spring on the right side 359 00:22:11,280 --> 00:22:14,199 Speaker 1: is the opposite. It's wound clockwise, so that when you 360 00:22:14,240 --> 00:22:18,160 Speaker 1: release the tension, it will spin the throwing arm counterclockwise. 361 00:22:18,920 --> 00:22:21,359 Speaker 1: And on the opposite end of the throwing arm, you 362 00:22:21,480 --> 00:22:25,480 Speaker 1: have a line attaching the two together, a rope if 363 00:22:25,480 --> 00:22:29,440 Speaker 1: you will or string this rope is looped around the 364 00:22:29,600 --> 00:22:32,320 Speaker 1: end of your projectile. This is the thing that's going 365 00:22:32,400 --> 00:22:36,040 Speaker 1: to transfer the force to the projectile and make it 366 00:22:36,160 --> 00:22:40,480 Speaker 1: fly at your target. So just imagine you've got this 367 00:22:40,520 --> 00:22:44,080 Speaker 1: crossbow looking thing in front of you. The two arms 368 00:22:44,080 --> 00:22:47,280 Speaker 1: of the ballista in its rest position you haven't wound 369 00:22:47,320 --> 00:22:52,040 Speaker 1: it yet, are extended outward to the side. So the 370 00:22:52,200 --> 00:22:55,320 Speaker 1: left one is is almost parallel with the front of 371 00:22:55,320 --> 00:22:57,080 Speaker 1: the ballist, of the right one is almost parallel with 372 00:22:57,080 --> 00:23:00,240 Speaker 1: the ballista, and you have a device called a wind us. 373 00:23:00,800 --> 00:23:03,680 Speaker 1: The windlass is what allows you to crank back those arms. 374 00:23:03,720 --> 00:23:08,159 Speaker 1: It's creating tension in those torsion springs, so it starts 375 00:23:08,160 --> 00:23:11,359 Speaker 1: to twist the torsion springs and as a result, the 376 00:23:11,440 --> 00:23:16,200 Speaker 1: two throwing arms start tilting back towards you. It's that 377 00:23:16,440 --> 00:23:20,639 Speaker 1: they've bend backwards, although the torsion the throwing arms themselves 378 00:23:20,680 --> 00:23:23,240 Speaker 1: are not bending. It's just the torsion springs are are 379 00:23:23,400 --> 00:23:27,600 Speaker 1: rotating as you're twisting them. Uh, so they've been backward. 380 00:23:27,680 --> 00:23:29,920 Speaker 1: Now that means that you start getting slack in that 381 00:23:30,040 --> 00:23:35,200 Speaker 1: rope that's between the two ends of the throwing arms. 382 00:23:35,760 --> 00:23:38,320 Speaker 1: You can use that slack to put it behind your projectile, 383 00:23:38,840 --> 00:23:42,360 Speaker 1: and when you release the tension on those torsion springs, 384 00:23:43,080 --> 00:23:47,680 Speaker 1: they untwist that pulls the throwing arms forward, and that 385 00:23:47,920 --> 00:23:52,800 Speaker 1: pulls that that rope forward as well, transferring the energy 386 00:23:52,840 --> 00:23:57,040 Speaker 1: to your projectile and shooting it at your target. It's 387 00:23:57,080 --> 00:23:59,960 Speaker 1: a pretty cool to see this, I mean, it's interesting 388 00:24:00,000 --> 00:24:03,199 Speaker 1: to see this as two torsion springs as opposed to 389 00:24:03,240 --> 00:24:07,439 Speaker 1: a crossbow, which would just use the tension of the 390 00:24:07,480 --> 00:24:10,520 Speaker 1: material itself, the wood, if you will, of the bow. 391 00:24:11,400 --> 00:24:13,560 Speaker 1: It's all due to mechanical physics. You don't need any 392 00:24:13,640 --> 00:24:18,040 Speaker 1: chemicals to do this kind of siege engine, and you 393 00:24:18,080 --> 00:24:20,800 Speaker 1: could also just build this thing when you needed it. 394 00:24:20,840 --> 00:24:25,200 Speaker 1: In fact, most siege engines were constructed at site where 395 00:24:25,240 --> 00:24:28,040 Speaker 1: the siege was happening, because they were so big and 396 00:24:28,080 --> 00:24:31,879 Speaker 1: heavy that moving them from one place across country to 397 00:24:31,920 --> 00:24:35,040 Speaker 1: another place was not really practical. So usually we just 398 00:24:35,040 --> 00:24:38,239 Speaker 1: go to the closest forest, cut down some logs, and 399 00:24:38,320 --> 00:24:41,760 Speaker 1: have some workers start to build siege engines right there 400 00:24:41,760 --> 00:24:44,000 Speaker 1: on site, wheel them in a place so that they're 401 00:24:44,000 --> 00:24:45,959 Speaker 1: generally pointed at the thing you want to shoot at, 402 00:24:46,280 --> 00:24:50,480 Speaker 1: and then you start firing. Uh. And the blister was 403 00:24:51,240 --> 00:24:54,159 Speaker 1: an early version of that the earliest ones were in 404 00:24:54,200 --> 00:24:58,320 Speaker 1: the BC era. Uh you would later see them go 405 00:24:58,480 --> 00:25:03,440 Speaker 1: all the way up through the Middle Ages. They were, however, 406 00:25:03,560 --> 00:25:07,480 Speaker 1: not terribly mobile. You could put wheels on the cart 407 00:25:07,560 --> 00:25:09,399 Speaker 1: for a ballista so that you could at least wheel 408 00:25:09,440 --> 00:25:12,119 Speaker 1: them into place, but it wasn't It's not like you 409 00:25:12,119 --> 00:25:14,640 Speaker 1: could easily move them once you planted them. They were 410 00:25:14,760 --> 00:25:18,720 Speaker 1: pretty much stationary once you were firing, and that meant 411 00:25:18,760 --> 00:25:22,040 Speaker 1: that they were pretty attractive targets. They were very accurate, 412 00:25:22,720 --> 00:25:27,480 Speaker 1: but they didn't hurl things at incredible distances. You could 413 00:25:27,480 --> 00:25:31,399 Speaker 1: get a decent distance with them, but they fired in 414 00:25:31,400 --> 00:25:34,520 Speaker 1: a very low arc like essentially, it was a straight 415 00:25:34,560 --> 00:25:38,200 Speaker 1: line from the ballista to the target. Um it kind 416 00:25:38,200 --> 00:25:41,720 Speaker 1: of came out horizontally that way. It didn't fire in 417 00:25:41,760 --> 00:25:45,280 Speaker 1: an arc the way catapults and tributches did. And it 418 00:25:45,320 --> 00:25:49,000 Speaker 1: also did comparatively less damage than catapults and tribushes, largely 419 00:25:49,040 --> 00:25:53,119 Speaker 1: because the projectiles it fired didn't have a lot of 420 00:25:53,160 --> 00:25:56,240 Speaker 1: mass to them compared to the rocks that you could 421 00:25:56,240 --> 00:25:59,440 Speaker 1: fire from a catapult or a tributsche. And like I said, 422 00:25:59,520 --> 00:26:02,800 Speaker 1: crossbows or bows in general work in a very similar way, 423 00:26:02,960 --> 00:26:05,959 Speaker 1: but this case it's just tension of the material itself 424 00:26:06,000 --> 00:26:09,160 Speaker 1: as opposed to a tortion spring um so it's your 425 00:26:09,200 --> 00:26:14,000 Speaker 1: basic spring action, but it's the actual tension of the 426 00:26:14,040 --> 00:26:19,400 Speaker 1: wood itself. Torsion springs are also very important in other 427 00:26:19,480 --> 00:26:24,120 Speaker 1: types of seige engines, particularly different types of catapults. Now, 428 00:26:24,160 --> 00:26:27,120 Speaker 1: the nomenclature here gets a little confusing because a lot 429 00:26:27,119 --> 00:26:29,439 Speaker 1: of people use the word catapult to refer to a 430 00:26:29,520 --> 00:26:32,719 Speaker 1: very specific type of siege engine, and other people use 431 00:26:32,800 --> 00:26:37,080 Speaker 1: catapult to describe an entire family of siege engines, including 432 00:26:37,080 --> 00:26:41,399 Speaker 1: Ballista in some cases. But essentially, catapults were meant to 433 00:26:41,440 --> 00:26:44,919 Speaker 1: hurl massive objects through the air. So in order to 434 00:26:44,960 --> 00:26:48,960 Speaker 1: avoid confusion, I'm going to talk about the Manganell and 435 00:26:49,040 --> 00:26:53,000 Speaker 1: the Tribuche, which are often both lumped under the general 436 00:26:53,040 --> 00:26:57,760 Speaker 1: category of catapult, but they operate in very different ways. 437 00:26:57,800 --> 00:27:00,560 Speaker 1: So let's start with the Manganell, which was that before 438 00:27:00,600 --> 00:27:03,680 Speaker 1: the Tribute. The Mangonell was a siege engine of the 439 00:27:03,720 --> 00:27:09,840 Speaker 1: Middle Ages, so it came to into development after the Ballista. 440 00:27:10,119 --> 00:27:12,760 Speaker 1: Ballista we're still being used in siegeons at that time, 441 00:27:13,800 --> 00:27:16,040 Speaker 1: and it's kind of like a one armed ballista but 442 00:27:16,119 --> 00:27:20,640 Speaker 1: popped on its side, So the ballista looks like a crossbow, 443 00:27:21,520 --> 00:27:24,399 Speaker 1: which you know has the horizontal bow, but if you 444 00:27:24,440 --> 00:27:27,879 Speaker 1: were to wield an actual bow, like the kind you 445 00:27:27,920 --> 00:27:30,919 Speaker 1: fire arrows from, you would hold it vertically. Well, the 446 00:27:30,960 --> 00:27:34,040 Speaker 1: manganell is like that. It's vertical, but it only has 447 00:27:34,040 --> 00:27:36,480 Speaker 1: one arm. You don't you don't have a lower half 448 00:27:36,520 --> 00:27:39,800 Speaker 1: to it. Uh, there's just the throwing arm and the 449 00:27:39,840 --> 00:27:43,439 Speaker 1: torsion spring, and the torsion spring is aligned horizontally instead 450 00:27:43,440 --> 00:27:45,760 Speaker 1: of vertically. So it's like that first example of the 451 00:27:45,840 --> 00:27:47,639 Speaker 1: rubber bands I was talking about, where you're holding your 452 00:27:47,640 --> 00:27:51,720 Speaker 1: thumbs side by side as the torsion spring. Same thing 453 00:27:51,720 --> 00:27:55,040 Speaker 1: with the mangonell. So the throwing arm when it's in 454 00:27:55,119 --> 00:27:58,639 Speaker 1: its rest position is vertical. More or less. There's actually 455 00:27:58,800 --> 00:28:02,959 Speaker 1: typically a stop so that it can't go completely vertical. 456 00:28:03,160 --> 00:28:06,440 Speaker 1: It will usually be at a pretty high angle. When 457 00:28:06,480 --> 00:28:09,960 Speaker 1: you wind the torsion spring, you pull the throwing arm 458 00:28:10,040 --> 00:28:14,560 Speaker 1: back until it's practically horizontal, and then you latch it 459 00:28:14,680 --> 00:28:17,600 Speaker 1: in some way so that it stores that mechanical energy. 460 00:28:17,640 --> 00:28:22,119 Speaker 1: It doesn't just release it. You load your manganel typically 461 00:28:22,160 --> 00:28:26,439 Speaker 1: with heavy stuff, and then you release the torsion spring 462 00:28:26,720 --> 00:28:30,280 Speaker 1: and that twists back to the rest position, which means 463 00:28:30,359 --> 00:28:34,600 Speaker 1: the throwing arm goes vertical and releases its projectile. So 464 00:28:34,640 --> 00:28:37,399 Speaker 1: a mangonel could have this bowl like end to it, 465 00:28:37,480 --> 00:28:40,280 Speaker 1: and that's where you would put your various projectiles. They 466 00:28:40,320 --> 00:28:43,560 Speaker 1: might be rocks or firepots, or, at least according to 467 00:28:43,600 --> 00:28:47,440 Speaker 1: some accounts, dead stuff. The dead stuff was meant to 468 00:28:47,520 --> 00:28:51,920 Speaker 1: hurt defenders in two ways. First, it's pretty psychologically devastating 469 00:28:51,960 --> 00:28:56,960 Speaker 1: to have corpses thrown at you, true story. Second, it 470 00:28:57,040 --> 00:28:59,800 Speaker 1: was thought of as a way to introduce disease into 471 00:28:59,840 --> 00:29:04,080 Speaker 1: a fortified location, so it's a kind of biological warfare. 472 00:29:04,160 --> 00:29:08,320 Speaker 1: You just throw bloated corpses into a city. It's pretty gross. 473 00:29:09,160 --> 00:29:11,600 Speaker 1: And the whole idea was just to weaken defenses and 474 00:29:11,640 --> 00:29:14,800 Speaker 1: also increase the chance that the defenders would just give up, 475 00:29:15,200 --> 00:29:17,640 Speaker 1: like they're throwing dead stuff at us. Let's let's just 476 00:29:18,280 --> 00:29:22,560 Speaker 1: run up the white flag and stop this. The manganell 477 00:29:22,640 --> 00:29:26,800 Speaker 1: fired projectiles at high velocity and at a low arc, 478 00:29:27,120 --> 00:29:30,240 Speaker 1: so it was a higher arc than the ballista, which 479 00:29:30,320 --> 00:29:32,800 Speaker 1: again was pretty much a straight line, so there was 480 00:29:32,840 --> 00:29:35,800 Speaker 1: a slight arc to it, but it was still fairly low. 481 00:29:35,960 --> 00:29:40,440 Speaker 1: It would aim stuff at walls, not typically over walls. 482 00:29:41,520 --> 00:29:44,800 Speaker 1: It could hurl heavier and therefore more devastating projectiles than 483 00:29:44,840 --> 00:29:47,360 Speaker 1: the Ballista. But it was also less accurate than the 484 00:29:47,360 --> 00:29:52,400 Speaker 1: Ballista was uh. It was meant to destroy defensive structures 485 00:29:52,480 --> 00:29:54,480 Speaker 1: rather than go around them. If you look at the 486 00:29:54,560 --> 00:29:57,880 Speaker 1: arc of projectiles from siege engines, Ballista are the lowest, 487 00:29:58,360 --> 00:30:00,560 Speaker 1: Manganelles would be next, and then Tribute Chase would be 488 00:30:00,600 --> 00:30:04,280 Speaker 1: nice high arcs Now, according to the resources I looked at, 489 00:30:04,760 --> 00:30:08,680 Speaker 1: Manganelles could hurl projectiles as far as feet, which is 490 00:30:08,720 --> 00:30:11,240 Speaker 1: a pretty fair distance to throw a massive stone using 491 00:30:11,320 --> 00:30:15,120 Speaker 1: pure mechanical power. And like other season Jin's, the real 492 00:30:15,200 --> 00:30:18,120 Speaker 1: genius by the manganell was that it was pretty simple 493 00:30:18,160 --> 00:30:20,800 Speaker 1: to construct. You could again just build it on location. 494 00:30:22,800 --> 00:30:25,960 Speaker 1: Next I will talk about tribouches and then lead it 495 00:30:26,360 --> 00:30:29,600 Speaker 1: with some cannon talk. But before I get into all 496 00:30:29,640 --> 00:30:32,880 Speaker 1: of that, let's take another quick break to thank our sponsors, 497 00:30:41,120 --> 00:30:43,240 Speaker 1: and now to talk about the Tribute Shade. It was 498 00:30:43,280 --> 00:30:47,480 Speaker 1: a very different beast than the Manganel. It was named 499 00:30:47,520 --> 00:30:50,800 Speaker 1: after a word an old French which means to throw over, 500 00:30:50,960 --> 00:30:52,760 Speaker 1: and that's kind of what the Tribute Shade did. It 501 00:30:52,840 --> 00:30:55,920 Speaker 1: through projectiles in a high arc, they could be used 502 00:30:55,920 --> 00:30:59,120 Speaker 1: to attack defensive walls, or just bypass the walls completely 503 00:30:59,120 --> 00:31:03,680 Speaker 1: and hurled pload into fortified cities. Having massive rocks raining 504 00:31:03,720 --> 00:31:06,240 Speaker 1: down on your homes as a powerful motivator when it 505 00:31:06,320 --> 00:31:10,720 Speaker 1: comes time to consider surrender. The Tribute shade didn't depend 506 00:31:10,840 --> 00:31:15,040 Speaker 1: upon torsion springs the way Ballista and Mengonells did. Instead, 507 00:31:15,320 --> 00:31:19,200 Speaker 1: it used a massive counterweight to provide the mechanical force 508 00:31:19,240 --> 00:31:23,000 Speaker 1: to hurl payloads. So it's essentially a lever. Or if 509 00:31:23,040 --> 00:31:26,440 Speaker 1: you prefer a see saw, so think of a seesaw, 510 00:31:26,560 --> 00:31:28,600 Speaker 1: but it has a long end and a short end. 511 00:31:28,840 --> 00:31:31,880 Speaker 1: The counterweight is on the short end and the long 512 00:31:32,040 --> 00:31:35,480 Speaker 1: end is what hurls the payload. So seesaws are pretty 513 00:31:35,480 --> 00:31:38,360 Speaker 1: good analogy. If you have a seesaw balanced in the center, 514 00:31:38,720 --> 00:31:41,880 Speaker 1: too identical weights will balance out. You put two kids 515 00:31:41,880 --> 00:31:44,520 Speaker 1: on there the way the same the seesaws right there 516 00:31:44,520 --> 00:31:48,400 Speaker 1: in the middle, they should even out and just balance 517 00:31:48,440 --> 00:31:52,640 Speaker 1: each other. But if you move the seesaw so that 518 00:31:52,680 --> 00:31:56,960 Speaker 1: the pivot point is off center, then the equal weights 519 00:31:57,280 --> 00:32:01,800 Speaker 1: on either end will change the of the actual orientation 520 00:32:01,920 --> 00:32:04,520 Speaker 1: of the seesaw. The shorter end will end up sticking 521 00:32:04,600 --> 00:32:07,120 Speaker 1: up in the air, and the longer end will rest 522 00:32:07,160 --> 00:32:10,880 Speaker 1: against the ground. Now, because your typical tribute she uses 523 00:32:10,920 --> 00:32:14,800 Speaker 1: a short arm to hold the counterweight. That means, by 524 00:32:14,840 --> 00:32:17,840 Speaker 1: this little experiment we just talked about, you would actually 525 00:32:17,880 --> 00:32:21,000 Speaker 1: need a lot more weight in the counterweight than you're 526 00:32:21,000 --> 00:32:23,880 Speaker 1: going to have in the payload. Otherwise, your payload just 527 00:32:23,960 --> 00:32:26,000 Speaker 1: is gonna sit on the ground and the counterweight would 528 00:32:26,080 --> 00:32:28,440 Speaker 1: just dangle in the air. It would not have the 529 00:32:29,240 --> 00:32:33,600 Speaker 1: weights sufficient enough to pull the lever so that it 530 00:32:33,840 --> 00:32:38,360 Speaker 1: flings your payload at your enemy. The counterweight was also 531 00:32:38,440 --> 00:32:42,640 Speaker 1: typically hinged, meaning that it could swing around on the 532 00:32:42,800 --> 00:32:47,800 Speaker 1: end of this short side of the the tribute shay 533 00:32:47,800 --> 00:32:52,120 Speaker 1: beam that allows that to swing around so it doesn't 534 00:32:52,240 --> 00:32:54,800 Speaker 1: risk hitting the ground and mucking everything up. It's kind 535 00:32:54,800 --> 00:32:57,400 Speaker 1: of like a ferris wheel ride. The compartments on affairs 536 00:32:57,440 --> 00:33:00,120 Speaker 1: wheel are hinged so that people inside the right are 537 00:33:00,160 --> 00:33:03,400 Speaker 1: always in an upright orientation with regard to the ground. 538 00:33:03,920 --> 00:33:06,360 Speaker 1: The same is true for tribute shay counterweights, at least 539 00:33:06,360 --> 00:33:10,600 Speaker 1: with most of them anyway. Now, the huge throwing arm 540 00:33:10,800 --> 00:33:15,120 Speaker 1: hurls payloads that are placed in a sling, so it's 541 00:33:15,160 --> 00:33:17,600 Speaker 1: not like it has a bowl at the end of 542 00:33:17,640 --> 00:33:19,960 Speaker 1: it the way a mangonel did, at least not your 543 00:33:19,960 --> 00:33:23,920 Speaker 1: typical tribute shay. Typically you would use a sling instead. 544 00:33:24,320 --> 00:33:27,520 Speaker 1: So if you don't know what a sling is, imagine 545 00:33:27,720 --> 00:33:32,200 Speaker 1: a pocket and you have two sides of this pocket 546 00:33:32,480 --> 00:33:35,880 Speaker 1: with cords coming from those two sides, one chord on 547 00:33:35,920 --> 00:33:39,080 Speaker 1: each side. Uh And typically the way you would use 548 00:33:39,120 --> 00:33:42,720 Speaker 1: a sling, as you put a rock in the sling, 549 00:33:43,080 --> 00:33:46,120 Speaker 1: you swing the sling around your head. You let go 550 00:33:46,200 --> 00:33:48,960 Speaker 1: of one of the chords while holding onto the other one, 551 00:33:49,160 --> 00:33:52,760 Speaker 1: and that releases the rock, slinging it at your target 552 00:33:53,120 --> 00:33:56,440 Speaker 1: hopefully and not behind you unless you're me, in which 553 00:33:56,480 --> 00:33:58,280 Speaker 1: case it goes wherever it wants to go, because I 554 00:33:58,320 --> 00:34:02,480 Speaker 1: can't use a sling in a tribute shame. One of 555 00:34:02,520 --> 00:34:06,160 Speaker 1: those two chords is permanently attached to the long end 556 00:34:06,480 --> 00:34:09,680 Speaker 1: of the arm, So you've got one end of the 557 00:34:09,719 --> 00:34:14,880 Speaker 1: sling permanently affixed to the tribute shay. The other chord, 558 00:34:15,040 --> 00:34:19,279 Speaker 1: the other end, has a large ring at the very 559 00:34:19,360 --> 00:34:22,799 Speaker 1: end of it, and on the very end of the 560 00:34:22,800 --> 00:34:26,680 Speaker 1: throwing arm itself, there's a little projection called the finger 561 00:34:27,160 --> 00:34:30,759 Speaker 1: that extends outward at a certain angle from the end 562 00:34:30,800 --> 00:34:32,480 Speaker 1: of the beam. And by certain angle, I mean you 563 00:34:32,560 --> 00:34:35,200 Speaker 1: determine what the angle is when you build the tribute shame, 564 00:34:37,480 --> 00:34:39,680 Speaker 1: so if you like it, you should have put a 565 00:34:39,760 --> 00:34:41,440 Speaker 1: ring on it. So that's what you do with the 566 00:34:41,480 --> 00:34:45,720 Speaker 1: tribute shay. You slide the slings ring over the finger. 567 00:34:46,719 --> 00:34:48,920 Speaker 1: So when you want to fire a payload, you have 568 00:34:49,000 --> 00:34:52,040 Speaker 1: to raise the counterweight into the upright position and lock 569 00:34:52,120 --> 00:34:55,400 Speaker 1: it in places. Typically you have a mechanism there to 570 00:34:55,480 --> 00:34:59,160 Speaker 1: keep it from sliding back down or to swinging back 571 00:34:59,200 --> 00:35:01,879 Speaker 1: down is the better way to say it. And then 572 00:35:01,920 --> 00:35:04,799 Speaker 1: you load your sling with whatever your payload is, like 573 00:35:04,840 --> 00:35:09,479 Speaker 1: a giant rock. You then take the ring that's on 574 00:35:09,480 --> 00:35:13,040 Speaker 1: one end and you slide it over the finger of 575 00:35:13,080 --> 00:35:19,400 Speaker 1: the throwing arm. When you fire the tribute shay, you 576 00:35:19,480 --> 00:35:22,959 Speaker 1: remove the block that allows the counterweight too, or locks 577 00:35:23,000 --> 00:35:25,040 Speaker 1: the counterweight in place. I should say this allows the 578 00:35:25,080 --> 00:35:29,879 Speaker 1: counterweight to fall. It forces the short end of the 579 00:35:30,480 --> 00:35:35,359 Speaker 1: lever down. The long end is forced upward, and as 580 00:35:35,440 --> 00:35:39,320 Speaker 1: it moves upward, centrifugal force, which is not really a force, 581 00:35:39,360 --> 00:35:43,800 Speaker 1: but never mind that centrigal centrifical force pushes the sling 582 00:35:43,880 --> 00:35:49,239 Speaker 1: outward um and so then as the arm moves through 583 00:35:49,280 --> 00:35:52,760 Speaker 1: this arc, the ring on the end of that finger 584 00:35:53,440 --> 00:35:57,480 Speaker 1: slips free. Once it hits the proper angle as you 585 00:35:57,560 --> 00:36:00,440 Speaker 1: determined when you were building the tribute shape. When it 586 00:36:00,440 --> 00:36:04,000 Speaker 1: slips free of the finger, it releases the payload, throwing 587 00:36:04,040 --> 00:36:07,280 Speaker 1: it in that high arc, and it sales majestically overhead 588 00:36:07,320 --> 00:36:10,839 Speaker 1: towards your target. And because the counterweight is heavy enough, 589 00:36:11,680 --> 00:36:15,799 Speaker 1: it descends very quickly, so the this means there's a 590 00:36:15,920 --> 00:36:19,399 Speaker 1: very high increase in linear velocity for the throwing arm 591 00:36:19,480 --> 00:36:22,920 Speaker 1: and thus the payload. The release angle of the payload 592 00:36:23,000 --> 00:36:27,000 Speaker 1: is dependent upon the angle of the finger. That little projection, 593 00:36:27,440 --> 00:36:30,240 Speaker 1: relatively little projection at the end of your tribute shape. 594 00:36:30,880 --> 00:36:33,880 Speaker 1: So if you want to change the release angle, you 595 00:36:34,040 --> 00:36:36,520 Speaker 1: change the angle of the finger, and then the ring 596 00:36:36,560 --> 00:36:39,360 Speaker 1: will come off at a different point in that arc, 597 00:36:39,920 --> 00:36:42,520 Speaker 1: and thus the payload will fly in a different arc 598 00:36:42,560 --> 00:36:45,440 Speaker 1: towards your target. Of course, you're probably not using perfectly 599 00:36:45,520 --> 00:36:51,600 Speaker 1: uniform stones, so it's not an exact science. You might 600 00:36:51,640 --> 00:36:54,600 Speaker 1: be using stones of slightly different weights, which means that 601 00:36:54,600 --> 00:36:57,880 Speaker 1: that's gonna change the arc as well. But still the 602 00:36:57,880 --> 00:37:03,680 Speaker 1: principle is fairly sound. And then we get to the 603 00:37:03,719 --> 00:37:08,640 Speaker 1: invention and more importantly, the employment of gunpowder in siege weaponry. 604 00:37:08,680 --> 00:37:12,040 Speaker 1: Gunpowder was actually invented in Asia centuries before it became 605 00:37:12,080 --> 00:37:16,040 Speaker 1: a useful tool in warfare. But it really wasn't until 606 00:37:16,080 --> 00:37:18,760 Speaker 1: about the fifteenth century that you would see massive artillery 607 00:37:18,800 --> 00:37:22,200 Speaker 1: guns regularly utilized in medieval Europe. There were a lot 608 00:37:22,239 --> 00:37:25,440 Speaker 1: of earlier examples and a lot of historical accounts that 609 00:37:25,480 --> 00:37:30,120 Speaker 1: at least say that cannons were in use, although the 610 00:37:30,160 --> 00:37:34,319 Speaker 1: definition of cannon has changed dramatically over the centuries, so 611 00:37:35,239 --> 00:37:40,640 Speaker 1: some of those accounts are difficult to um verify, simply 612 00:37:40,680 --> 00:37:44,200 Speaker 1: because the cannon that's being referred to in one battle 613 00:37:44,640 --> 00:37:47,680 Speaker 1: maybe a significantly different kind of weapon than one from 614 00:37:47,680 --> 00:37:54,879 Speaker 1: another battle. Uh. There's definitely some evidence of cannons being 615 00:37:55,000 --> 00:37:57,279 Speaker 1: used in sieges though, and in the Hundred Years War 616 00:37:58,200 --> 00:38:02,160 Speaker 1: in northern France. England employed some cannons in a battle 617 00:38:02,160 --> 00:38:05,719 Speaker 1: in thirteen forty six. How many cannons, well, that kind 618 00:38:05,760 --> 00:38:08,239 Speaker 1: of depends upon which historical account, and you believe it's 619 00:38:08,280 --> 00:38:11,759 Speaker 1: somewhere between five and twenty six. And the English won 620 00:38:11,800 --> 00:38:14,440 Speaker 1: the battle. So was that because of the devastating power 621 00:38:14,480 --> 00:38:20,120 Speaker 1: of their fully operational death stuff. I'm sorry, cannon's probably not. 622 00:38:20,360 --> 00:38:23,040 Speaker 1: In fact, the English cannons likely did very little actual 623 00:38:23,200 --> 00:38:27,080 Speaker 1: damage against the Genoese mercenaries. They were fighting the Genoese 624 00:38:27,160 --> 00:38:30,560 Speaker 1: mercenaries were fighting on behalf of France, but it really 625 00:38:30,560 --> 00:38:33,520 Speaker 1: scared the pantaloons off those guys because the Genoese were 626 00:38:33,960 --> 00:38:37,719 Speaker 1: really rattled by those loud, smoky weapons and they were 627 00:38:37,760 --> 00:38:40,920 Speaker 1: soundly defeated. But the actual defeat came at the hands 628 00:38:41,040 --> 00:38:45,360 Speaker 1: of traditional English soldiers wielding stuff like swords and axes 629 00:38:45,360 --> 00:38:48,800 Speaker 1: and bows rather than the cannons. And besides, that's not 630 00:38:48,840 --> 00:38:51,120 Speaker 1: even really a siege, so I'm not really gonna talk 631 00:38:51,160 --> 00:38:55,440 Speaker 1: anymore about it. By sixteen seventy, you'd actually see the 632 00:38:55,480 --> 00:38:59,080 Speaker 1: word cannon being used to describe specific types of guns. 633 00:38:59,120 --> 00:39:03,279 Speaker 1: Mounted guns, typically stationary ones like you could roll them 634 00:39:03,280 --> 00:39:07,000 Speaker 1: into place, but they weren't meant to be moved around rapidly. 635 00:39:08,160 --> 00:39:11,080 Speaker 1: The biggest one at that time was called the cannon Royal, 636 00:39:11,600 --> 00:39:15,480 Speaker 1: and typically cannon Royal would weigh around eight thousand pounds 637 00:39:15,600 --> 00:39:18,960 Speaker 1: or three thousand six ms if you prefer and it 638 00:39:19,040 --> 00:39:23,439 Speaker 1: could fire cannonballs weighing at around sixty three pounds or rams. 639 00:39:23,520 --> 00:39:29,040 Speaker 1: That's massive. Then you had whole cannon and dimmi cannon guns. 640 00:39:29,440 --> 00:39:32,920 Speaker 1: Those were of decreasing size and weight and could fire 641 00:39:33,360 --> 00:39:36,640 Speaker 1: smaller cannonballs, and by smaller I mean that the smallest 642 00:39:36,640 --> 00:39:39,479 Speaker 1: gut down to be about twenty eight pounds. They're still 643 00:39:39,800 --> 00:39:42,080 Speaker 1: really heavy, particularly if you compare them to the types 644 00:39:42,120 --> 00:39:44,719 Speaker 1: of cannon you'd find on sailing ships a century later. 645 00:39:45,680 --> 00:39:51,440 Speaker 1: Eventually we would refer to cannon by the the weight 646 00:39:51,560 --> 00:39:54,520 Speaker 1: of the shot they fired. What kind of cannonball would 647 00:39:54,560 --> 00:39:57,919 Speaker 1: they fire? So if you hear about a ten pound gun, 648 00:39:58,560 --> 00:40:01,440 Speaker 1: it meant that the shot it fired aired weight ten pounds. 649 00:40:01,480 --> 00:40:04,440 Speaker 1: The gun itself didn't weigh ten pounds, it weighed weigh 650 00:40:04,480 --> 00:40:08,279 Speaker 1: more than that, but the cannonballs weighed ten pounds. So 651 00:40:08,280 --> 00:40:11,000 Speaker 1: if you're about a twenty pounder, that meant that the 652 00:40:11,040 --> 00:40:14,480 Speaker 1: cannonballs weighed twenty pounds. So the bigger the pound edge, 653 00:40:14,520 --> 00:40:17,920 Speaker 1: that just means the heavier the shot, and thus the 654 00:40:17,960 --> 00:40:20,520 Speaker 1: more damaged the cannon would do if you hit what 655 00:40:20,640 --> 00:40:24,760 Speaker 1: you were aiming at. Well, the cannon made earlier city 656 00:40:24,800 --> 00:40:28,680 Speaker 1: defenses completely useless. High walls were not good protection against 657 00:40:28,760 --> 00:40:31,680 Speaker 1: cannon fire, which typically fire in a pretty low arc 658 00:40:31,719 --> 00:40:37,800 Speaker 1: at a very high velocity, so instead new defenses were invented. Essentially, 659 00:40:37,880 --> 00:40:40,360 Speaker 1: new walls were built, and these were lower walls and 660 00:40:40,480 --> 00:40:44,840 Speaker 1: thicker walls. Defensive walls were made to withstand high impacts 661 00:40:44,840 --> 00:40:48,360 Speaker 1: from cannon fire, and because defenders would often have guns 662 00:40:48,360 --> 00:40:51,680 Speaker 1: of their own, traditional methods of breaching walls were pretty 663 00:40:51,800 --> 00:40:54,080 Speaker 1: bad choices. It doesn't make a whole lot of sense 664 00:40:54,120 --> 00:40:59,200 Speaker 1: to wheel a siege engine slowly toward a wall. If 665 00:40:59,200 --> 00:41:02,839 Speaker 1: you're being fired pawned by cannon, you'd be a sitting duck. 666 00:41:03,640 --> 00:41:08,319 Speaker 1: So it completely changed warfare from that moment forward. You 667 00:41:08,400 --> 00:41:12,719 Speaker 1: also saw other changes as well, from armor to swords 668 00:41:12,800 --> 00:41:16,680 Speaker 1: and all sorts of stuff, all because gunpowder had entered 669 00:41:16,719 --> 00:41:20,000 Speaker 1: the scene. Cannons themselves are fascinating all the way, from 670 00:41:20,000 --> 00:41:23,120 Speaker 1: the early bronze guns to the steel guns that redefined 671 00:41:23,160 --> 00:41:26,360 Speaker 1: warfare yet again, but that warrants its own episode. For now, 672 00:41:26,960 --> 00:41:29,399 Speaker 1: I need to say farewell, and I need to get 673 00:41:29,400 --> 00:41:32,280 Speaker 1: ready for the Renaissance Festival.
