Errores

When Gar and the Greys leave the house, Gar is holding a cloth bag. Later, the bag becomes larger and holds many cooking utensils, beans, and other food.

The repeating Henry rifles brought to the fort just in time are not loaded, but when they are passed up to the men defending the fort atop its walls along with boxes of ammunition, the men begin shooting them immediately, before they are loaded.

As the Comanches charge Fort Dobbs, the camera angle from behind them shows the defenders already shooting from the Fort. However, when the next camera angle shows close ups of the defenders, none are shooting or reloading--they would be doing one or the other if they had started to shoot.

The flag flying over the fort has 37 stars, in a 7-8-7-8-7 row pattern. The actual 37-star flag of the U.S. from July 4, 1867 until July 3, 1877 had an 8-7-7-7-8 row pattern, with the end stars on the first and last row extending over the other three rows.

The Henry rifle that Clett shows Gar and says he hasn't seen yet, was introduced in 1860 13 years before the 1873 Colt revolver Gar was using.

When one of the defenders is hit in the chest with a spear, the camera pans from the Comanche throwing it to the defender receiving it. However, when the shot focuses on the defender, the long spear is already embedded in his chest, a second later he recoils as if being hit.

When the defenders shoot for the first time, one defender is shown immediately loading his rifle. However, this would have already been done if he had not shot before.

Virginia Mayo wakes up after her ordeal in the river, with false eyelashes and makeup intact, and her hair perfectly dry and styled.

Several scenes show the Indians attacking across a river. There is no river near Fort Dobbs. Warner Brothers used a lot of scenes from different movies over and over to save money.
