About archery... we have differents schools about that. A different point of view on that topic (modern/classical/Europe/Asia) and Bannerlord is not simulating fight that much. That is not a short topic or only one point of view.
For example sword, we have only 4 swings and one stab(is like using a sword only in 10%). We can't use hands in sword fighting. Fight in Bannerlord is very simply. For all of the types of swords! This game doesn't have longsword or short sword, bastard, or saber, this game has a one-handed weapon "sword".
In
Lars Andersen: A new level of archery we have an example of how we can shoot.
In
HEMA instructors fighting with the Polish saber - Lee Smith vs. Richard Marsden we have saber fighting (yes, this is the end of XVI century) in here the most important thing is hitting the enemy saber when in the IX century hitting sword vs sword was not the best idea (because of smithing).
In
Akademia Szermierzy - Fior di Battaglia: Chapter II (The Guards of the Sword) we have long sword fighting from the XIII century and later.
In
Adorea longsword fight duel we have "cinematic" fighting where 95% of the fight is historical.
In
Wolin 2017 Viking Battle - "Wrath of Jomsborg" we have more like street fight not actually historical combat, but pretty messy. What here is interesting is that they have armor like "lords" and cutting is useless here. Cutting mail armor is very very hard... and below mail you have other layers of armor. Okay is possible to cute something, but for armor, you should use piercing or blunt weapons or simply push the enemy on the ground.
and more...
as you see we have very different styles in fighting using swords. Bannerlord is not historical fighting game but a game where you are a "lord" and you have fun
