At the beginning of the final battle, Fleurette runs out to give a weapon to John Breen. She brings neither a shot pouch or powder horn. Breen is also carrying neither of these items. However, he is somehow able to reload and fire the musket a number of times thereafter.

Near the end of the film when the riders raid the French cabin, there are seven riders. But, ten men surround and enter the cabin. Then, one is shot. They then chase the French in the wagon, with scenes showing 6,7, or 8 horses at different times.

When the soldiers are starting their march from Mobile, Alabama, to their home in Kentucky, they sing, "Only 800 miles more to go". In reality, the distance from Mobile to Kentucky is only about 400 miles.

When Breen is locked up, his knife is still in its scabbard on his belt. They would have made sure he was unarmed when locking him up and would have taken his knife.

During the huge scramble for the jug of whiskey, the jug is being tossed around and men tackle the holder of the jug similar to a rugby game. In one scene the jug lands in French soldier's hands and he and Oliver Hardy tussle over it. As the soldier breaks away from Hardy he drops the jug from a height of approximately 2 feet, and the jug bounces off the ground back up into the soldier's hands like a basketball.

The river men chase the French from the cabin back to the French fortified camp. As they flee, the French go up a hill over a small trail and turn onto a large dirt road. In both wide shots of first the French riding towards the camera and then of the river men chasing behind also towards the camera, the dust on the road reveals wide tire tracks with visible treads --much wider than any wagon wheel of that time-- that were made by the camera vehicle .

During the final battle, when Breen & Fleurette are lying behind a fallen tree, a jumping horse lands, one of its forefeet landing squarely on one of Breen's legs, which would have caused a serious injury. ("Breen" in this shot is obviously a dummy).

A number of times the background music uses pieces of "La Marseillaise". Although associated with revolutionary and modern France, the song was banned by Emperor Napoleon.

Willie talks of Kentucky and says "Ma is baking bread and you can smell it all through the house." He is referencing an early-to-mid 20th Century stereotype. At that time of the movie the typical house in Kentucky would have had only one or two rooms with an exterior kitchen under a lean-to. As almost all work was done outside the house, the smell in the house would not have been noticed.

The "2nd Kentucky Regiment" is shown marching in step. Frontier militia units of that day were rarely trained in formal marching, being raised in response to a specific, short-term need, and disbanded as soon as possible to save money. Also, no unit would march in step unnecessarily, as it was tiring to the men.

Near the end of the film a soldier drives a two-horse buckboard wagon from left to right in front of the Mansion. As he drives by you can see the shadow of the camera and other equipment on the side of the wagon.

During the party with music in the Mansion near the end of the film, it is obvious when watching all the violins being played that John Wayne and Oliver Hardy do not know how to play the violins; they aren't even close to pretending to play the instrument.

General de Marchand is obviously not French. His accent sounds more Germanic.
