Continuity: When Mrs. Collingwood calls Mrs. O'Rourke over to help Phil setting up their place, Mrs. O'Rourke comes rushing in with a few other people in tow. However, seen from inside the room only Mrs. O'Rourke enters.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Audio problem: When one of the soldiers serenades outside the O'Rourkes' place he is accompanied by an accordion and a guitar. However, what you hear is an accordion and a banjo.

Continuity: 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 One spindly volunteer gallops off first, but when we see him from behind he has been replaced by a stuntman of about twice his width.

Continuity: When Col. Thursday skips his dinner because an alarm came in he apologizes to Phil. While they are talking Phil's purse appears in her hands from one shot to the next.

Plot hole: When the alarm from Fort Grant comes in Col. Thursday skips his dinner and rushes to the headquarters. Given the danger of the situation as well as his meticulous sense of duty (also of his subordinates') he'd for sure have summoned his next in line, the Capts. York and Collingwood and Lt. O'Rourke, who are enjoying an undisturbed dinner party at the Collingwoods' quarters.

Revealing: Before the first encounter with the Apache, O'Rourke Jr. is looking out for Indians hiding behind a trunk. When he is being shot at and two bullets hit the trunk you see tiny volcanos erupt which obviously have been filled with explosives.

Audio problem: When the musicians walk off after their serenade they intonate another song without anyone moving his mouth.
