from Henry V's time :
from here : http://www.slate.com/blogs/quora/201..._fighting.htmlOn campaign, arrows were bulk-packed in barrels and transported in wagons. Longbowmen might be issued with three sheaves of 24 arrows each to carry into combat, and during a long battle runners would be sent to bring more arrows from the wagons.
Note this was the English longbowmen on royal campaigns.
Baronial armies would have had fewer, as would local militia archers.
Peasant archers wouldn't have been supplied by Royal Armouries either, probably had to supply their own so should have correspondingly even fewer arrows.
On that basis you could allow 72 arrows for English Royal longbowmen ; 48 arrows for local baronial and town militia archers and perhaps 24 for peasant archers.
