Other mistake: At the start of the trench running scene where the soldiers charge, keep looking at the far left of the screen. You will see a small group of soldiers already running who were not in the trenches. In addition, they seem to be running without weapons.

Plot hole: The letter that had to be delivered to the Colonel should have been completely ruined when the Corporal was in the river.
Question: Does Schofield throw away his canteen after he pours water over his eyes? In any event he has it again to fill with milk at the abandoned farm house.
