Other mistake: When Martin and his younger sons attack the soldiers Gabriel sent to their camp, the body count totals 20. That includes the private who gets up and tries to run that Martin hacks to death. Later when Tavington is questioning the wounded private the Cherokee scouts brought in, he indicates he was in the fight. But Tavington states 20 soldiers were killed and the ambush shows 20 being killed. Where did the private come from?
Suggested correction: There are 21 soldiers in the group. Samuel kills one with a rifle. Nathan kills six with a rifle. Benjamin kills four with his rifles, one with a pistol, six with his knife and tomahawk, two with redcoat rifles, and shoots the injured man into the stream.
Continuity mistake: In the final confrontation between Benjamin and Tavington, when Tavington is charging and Benjamin is running at him with the flag, during the closeups of Benjamin, he's charging at Tavington, but when the focus shifts to Tavington, Benjamin can be seen in the foreground already kneeling, with the shaft of the flag planted in the ground. This back and forth occurs 2 or 3 times and each time Benjamin's position is different, until he flips Tavington's horse.
Continuity mistake: In the final battle (Cowpens) when the milita are lined up, and Ben says "Take aim!" the first time, watch the guy behind Ben. The camera will show Ben and Jean(French guy). It will then show the line of milita aiming. Then the camera goes back to Ben and Jean. There is a different guy behind them. (02:32:35)
Continuity mistake: In the scene where the boys go down to the river and see the bodies floating, Benjamin tells his daughter to go bring them back. As she is running through the field you see her trip into the grass right before they switch camera shots. where she is standing with her brothers like nothing happened. (00:24:45)
