What are most of the manuals depicting and teach? Is it how to survive on the battlefield primarily or is it how to survive a man on man fight?
In the modern military they teach hand to hand combat in an individual format, meaning to each individual, and it is intended for the battlefield so why would it be diffrent 400 year's ago when the fighting was alway's at "bayonet distance" in modern term's, I think that the common misconception is that you won't go to the ground in actual combat because it is too dangerous and what about his buddies and so on and so forth, to me that is a load of Bull crap.
Idealy you don't want to go to the ground, combat though is never ideal, they have alot of quote's in the military and one i remember well is "Plan for the worst hope for the best" which in this case is learn to fight from and on the ground do your best to not go there, although it will happen eventualy if you are in combat long enough, if you do not know how to fight from/on the ground and you go down you have no advantage over your enemy.
MHO is that the manuals are more focused on the duell or man to man fihghting and is not primarily intended for battlefield fighting
I do not agree i think what we see is advanced individual training or in modern U.S. Army term's AIT, for the time period the manuel was written, combat is combat whether it is a mely or individual duel the skill's are no diffrent it is all combat, If I challenge you to a duel with a longsword even only to first blood we are both going to have the same feeling's as if it were a mely combat for the simple fact that someone will sustain grave bodily harm and possibly death, only dueling to first blood does not gaurentee that it will not result in death and we have a set of rule's which we agree upon to limit thing's it is still combat and anything can happen even accidently.
In a man on man situation there is often alot of room around, on a batllefield this is not the case.
in general combat if you attack a fortified position or a defended position you go in and try to fight each individual not the whole unit it would be man to man because i am not attacking alone i will have the rest of my unit be it a squad, platoon, whatever, we are all attacking and fighting one or two men (hopefuly) at a time, and there will be crap laying everywhere, in a duel you only have limited gear in the arena so in that respect you wouldn't have to worry about it, and remember the police have very diffrent rule's when it come's to the use of lethal force than the military in a war time situation.
this is my opinion and i think it is well qualified having seen a modern battlefield, before, during and after combat. I doubt the battlefield of the 14th-15th century would have been much diffrent except for the gear lying around would have been dead horse's, sword's and shield's as opposed to burned out BMP's, AK 47's and RPG's.
I do not realy think there is a distinction between combat of a duel and that of the "Battelfield" in the way you train to fight.
