I've red a text of an historian who think the romans didn't use crossbow for battle but for hunting because they don't have enough informations of this during war (but maybe they used the same arrows than bows, so they maybe use a generic name for bow and crossbows).
but yes, low accurate is generally more intereting during war than hunting !
I always tried to imagine a "arrow cloud" shooted from warbows at the end of Middle Ages... about 12 arrows a minute shooted by several thuisands archers... about 1 million arrows shooted in about 30 minutes, about 4-5 arrows for each square meters on the ground... medieval people said it was snowing because the fletching was white. -snow cloud of war-
Maybe I'm a coward, but I prefer being in front of my computer than showing this in front of me!
