In the final battle, Capt. Tremaine is struck by Tyreen and falls from his horse into the river, but in the very next shot he is back in the saddle.

When Maj Dundee and the relief column arrive at the Rosta's ranch, Dundee is not wearing a blue jacket. As he, Potts, and Ryan go into the massacre site he is still without his jacket and it is not visible on his saddle.

Shortly later, as Dundee, Potts, and now with Sgt Gomez approach the trooper hanging upside down, Dundee is now wearing his blue jacket, though not buttoned.

When Ryan and Linda are talking to Tyreen and Dundee in the village, she has a bright red shawl wrapped completely round her. However, in the shot as she and Ryan walk away, the shawl has dropped off her shoulders and is held around her upper arms.

During the fiesta in the village the serape worn by Maj. Dundee changes from folded up to half folded up while he is being cut in by Lt. Graham.

In the final battle, the French lancers signal their charge with an American bugle call.

The type of howitzer used by Lt. Graham in the M1841 12-pounder Mountain Howitzer, a small but effective piece used primarily as horse artillery. In the final battle, Graham orders that the piece be elevated to 28 degrees; the highest level that can be reached for this piece is ten degrees.

As the troop is leaving Fort Benlin for Mexico, Dundee orders the bugler to "whistle me a tune". When the bugler starts his tune, each of the different groups breaks into their own song. The civilians begin singing "My Darling Clementine". This song, with the lyrics used, was written around 1884, roughly 20 years after the period in which the movie is set.

During the village fiesta, the fiddle player in the mariachi band never moves his fingers on the fret, and barely moves the bow at all.

The film takes place during the American Civil War, which ended in 1865, and the New Mexico state flag is shown in the garrison office. However, New Mexico didn't become a state until 1912 and the flag wasn't designed until after that--about 1920.

At the end of the battle attempting to cross a river, one of the black soldiers is shown easily carrying the howitzer in his arms. The man would have to be very strong, as the barrel of a 12-lb. Mountain Howitzer would have weighed over 220 pounds.

During the village fiesta, the mariachi band has no horns, only guitars and fiddles, yet the audible music is mostly trumpets.

During the village fiesta, the mariachi band has a fiddle player, yet no fiddle can be heard, only horns and guitars.

Major Dundee hardly ever returned a salute from any of his subordinates, as is required by military protocol.

Early in the film, a young girl is playing the guitar. When there's a distinct change of chord, her left-hand fingers do not change position.
