They were charging up hill in the mud. Noone really died from arrows, except maybe some of the horses. But a lot of their horses fell and then the knights ran back through their own infantry, though apparently that wasn't that big a deal in the battle.
The battlefield killing was done by light infantry wading in with daggers and hatchets apparently during a foot slog up the muddy hill which left the french heavy infantry exhausted. Another wave of killing afaik was when the captured prisoners were all executed since the english position seemed like it might be overrun by some follow up fighting.
(keep in mind the battle took hours and there was a lot more going on then just heavy horse riding up against arrows once or twice)
