“At Agincourt the French Knights evidently resorted to a charge on foot, either because a significant majority of their cavalry mounts were disabled, or because they saw the futility of further mounted charges.”
I saw a show on the History Channel where they did soil analysis and determined that because of the clay content the soil wouldn’t drain. It had been raining heavily and they suspect the heavy chargers couldn’t negotiate the mud.
Saw the same program. I also remember the computer-aided “traffic analysis” that they did to show how jammed up the French knights were. They were so jammed, the theory went, that they couldn’t employ their weapons and were easily taken prisoner by the English infantry — even the archers.
A lot of the French Knights were killed after the battle by their captors. Some say that this was evidence of a command failure on Henry’s part. Those Knights were worth a lot of ransome money if Henry could have gotten them in-hand. Instead the English yeoman just butchered them. It’s also possible that Henry didn’t want these knights repatriated when he knew he might have to fight them again.
