Arrow's fly high

Then began the death-bearing clouds of arrows. There followed the thunder of blows. The clash of helmets and swords produced dancing sparks. Harold had placed all his people very closely in a single line, constructing a sort of castle with them, so that they were impregnable to the Normans. Duke William instructed the archers not to shoot their arrows directly at the enemy, but rather into the air, so that the arrows might blind the enemy squadron. This caused great losses among the English. --Henry of Huntingdon
