I've heard about the battle of Agincourt that many knights probably died of drowning as they fell and their helmets filled with mud. It got me thinking: If you're going into battle on foot and in full-plate, what is the most likely cause of death for you? You're either going to walk away from the battle or die there. In the case you don't survive, how is that likely to go down? Did soldiers in full-plate know how their armor would likely be defeated if they became exhausted or disarmed?
Would the enemy soldiers try to disarm you? If so how would they do that and how would they then finish you? How would they get through your armor? Would they knock you down and try to wrestle a piece of your armor off and then stab you there? Or could they find weak points in your armor through which to stab you? Would they just hit you with hammers until the dents in your armor kill you by asphyxiation or trauma? Might they purposefully try to drown you in the mud?
