Historians disagree to this day about both the number of combatants and the number of casualties, on either side, at the Battle of Agincourt. While it is accepted that Henry's army was outnumbered by the French, ratios range anywhere from 2.5 to 1 all the way to 5 to 1 (as stated in the play). In any event, Agincourt was a battle the French "should" have won, considering sheer numbers. As it happened, the English victory was due, in large part, to a combination of weather, topography, weaponry, and overall plan of battle, and most deaths were the result of crush injuries (from falling horses and soldiers) and drowning (in mud that was, in places, knee-deep).
