Continuity: In the final battle, Captain Tremaine is struck by Tyreen and falls from his horse into the river, but in the very next shot he is back in the saddle.
Factual errors: Prior to the final battle, Captain Tyreen is shown inserting cartridges into what should be a muzzle loading pistol.
Factual errors: The type of howitzer used by Lieutenant Graham in the M1841 12 pounder Mountain Howitzer, a small but effective piece used primarily as horse artillery. In the final battle, Graham orders that the piece be elevated to 28 degrees; the highest level that can be reached for this piece is ten degrees.
Factual errors: In the final battle, the French lancers signal their charge with an American bugle call.
Anachronisms: At the end of the battle attempting to cross a river, one of the black soldiers is shown easily carrying the howitzer in his arms. The man would have to be very strong, as the barrel of a 12-lb. Mountain Howitzer would have weighed over 220 pounds.
