The correct answer is:
English soldiers used archery to defeat French knights.
During the Hundred Years' War (1337–1453) the longbow was proven most effective since it was key on ensuring the famed English victories at Crécy (1346), Poitiers (1356), and Agincourt (1415). However, they were not victorious at the Battle of Verneuil (1424), and at the Battle of Patay (1429) when they were charged before they had set up their defensive position.
