Continuity mistake: When Beaufort instructs the new bunch of recruits he is standing right in front of their line. When the camera angle changes he is standing about two meters away. You can tell the difference best when you look at his shadow. (00:44:00)
Continuity mistake: A group of new recruits is introduced to horseriding. One spindly volunteer gallops off first, but when we see him from behind he has been replaced by a stuntman of about twice his width. (00:44:10)
Continuity mistake: When the group of soldiers with the coach goes full speed back to the fort the camera pans to the Apache ambushing them. After a few seconds the camera cuts back to the coach, which should be already out of sight but is still where we saw them before. (00:57:50)
Continuity mistake: Before the last and devastating battle begins York and O'Rourke lead the wagons to a ridge. In alternating shots the wagons are passing by an enormous rock or going through open plains. (01:47:45)

Thursday onto his horse and Thursday asks for and receives Captain York's sword. Minutes later Captain York is back with his men and is wearing another sword. Where did it come from?
