[Incabulos]

accounts of Crecy describe porters continually bringing arrows from the supply lines.

It also described that a ferocious rate was only needed for the first charge. The resulting field of long arrows and crippled horses etc meant the second charge was much less of a threat.

A barrier of dead horses was actually achieved. Of course Crecy is an example of where the longbow really shined, and was put to great tactical use. The terrain forced a difficult charge and approach from a single direction.

In modern tests they did show that it wasn't until the last 1/4 of a charge (when the knights were almost at the base of the hill) that the arrows penetrated armor. The first 1/4 of the charge and almost no arrows hit even the horse. The last 1/4 of the charge almost all the arrows would hit. The targets looked like hedgehogs.\\they also timed the charge to cover the field and it took 40 seconds. That is an awful long time to be under fire from that many longbows. Crossbows simply would not have been as effective.

Seems to me crossbows would excel at taking down slower moving heavily armoured infantry.
