This scene is a little after the attack the Ben Martin made on the Red-Coats to save his son. When the bad guy Colonel walks into the tent to question the injured soldier, he has a strap around him. The strap is on top of his collar when he walks in. However, when the camera cuts to the soldier, and then back to him again, the strap is under his collar. This happens maybe 3-5 times throughout this scene.
