ARROWS vs ARMOUR - Medieval Myth Busting

The youtube channel Todd's Workshop did an interesting video with Tobias Capwell and a few others examining the effectiveness of English longbows against plate armor that I found interesting in a number of respects. In the video they had archer Joe Gibbs shooting a 160lb longbow. For this, he uses a posture that looks unusual by modern archery standards but which is evidently supported by contemporary illustrations of English longbowmen. Apparently this unusual posture is the only way he can manage to draw bows like this at all (he can draw up to 200lb bows like this.) He seems to be able to hold the bow drawn for a moment or two, but it's a far cry from what movies generally depict. [this video]

A crossbow has several advantages, but it's main advantage is NOT power or armor piercing ability. That is likely a myth perpetuated by armchair historians with poor grasp of physics. The main advantage of a crossbow is that it's easy to use. Richard Lionheart, the English king, was famously killed by a boy wielding a crossbow. You need no more than 2 weeks to be proficient with a crossbow. To do that with an English longbow you'd need 7 years. There are various methods of drawing a crossbow that don't require great strength. Here's a (not exhaustive! Missing is for example latchet crossbow.) list of 9 ways to draw a crossbow: Tod's Workshop 9 MEDIEVAL CROSSBOW DEVICES - How do they work? ------------------- [link] In the video, Tod Cutler shows 9 mechanisms used to span a crossbow, some of them require a specially modified crossbow and some don't. Crucially, he shows the numbers for mechanical advantage. Keep in mind the input number will vary. Cranequin is an amazing mechanism, but you only use a single hand. A windlass doesn't have such an impressive ratio , but you can use both hands. A belt may let you use your back muscles as well. Videos of Joe Gibbs, a 170lb man who can draw a 200lb longbow, show how much effort it is. In one of the videos - I can't locate which one it is - he explains it's no coincidence medieval illustrations show people bending forward when drawing a bow. He draws this way and it lets him put a little more extra into the arrow. Crossbow can be kept
