I disagree. It really doesn’t take that much skill to use most any hand weapon effectively. For example, consider the quality of the soldier and training of the people who actually used these weapons.
Most of the people I train can hold their own against somebody who has trained for a couple of years (keeping in mind that most duels are over in moments, so what I really mean is that the win-loss ratio is pretty decent even for rookies vs slightly trained swordsmen). That being said somebody who trains for many years will eventually truly master the weapon at which point you will start to see some real wholesale slaughters (in terms of win-loss ratios again). Case in point, my instructors beats me handily since he has been training for a VERY long time and I have only been training a long time.
In any event, swordplay on the battlefield of the time was essentially non-existent. There is no room or time for duels to take place. Lots of shoving, bodies in your face, yelling, blood, confusion, etc.
Keep in mind that the bow as a military weapon was used en masse. Frankly, the military of the time could care less if you could hit the bullseye 9/10 times. They just wanted you to be able to get the arrow in the general vicinity of the opposing army. Again, not a lot of skill involved.
True, discounting mindset, which I didn’t consider in the previous two cases so I won’t here.
