Goofs

Johnny returns to the wagon train after Rosita is attacked, but before he delivered the money to O'Connor.

After O'Connor's attack on Lucia, a mystery man speaks to her from outside, telling her the door is open. It would have been easier to open the door and tell her so. Besides, she would be the first to know - as O'Connor had left her on hearing the fire alarm.

The caravan of settlers that is on their way through the Oregon trail consists of four wagons only, exactly the same number of wagons employed by the Rangers to convoy the explosives. Also, the number of men and women seen together during a night camp, watching a dance number, would not fit into those four wagons.

Pecos' gang, the Rangers' company, and O'Connor's army of desperadoes seem to grow in numbers from the first scene to the last where they appear, which is not coherent with the number of losses in combat.

Lucia Cansino, Sam More and Pete Lopez are attacked by O'Connor's men and arrested in cells without a body-check that would reveal respectively, the blasting caps, the letter with secret instructions, and a 20 cm blade. In Lucia Cansino's case, even O'Connor's sexual attack didn't expose the blasting caps.

Lucia Cansino is so lucky in her escape from O'Connor's hideout that she does not cross a single guard outside, and finds a saddled horse alone in that barren piece of mountain.
