The Horse Soldiers (1959)

Continuity mistake: When Colonel Marlowe blows the bridge near the end of the film, a pair of spectacular explosions ensue, tossing planks and beams into the air. However, as Hannah Hunter gazes at his retreating form, the bridge is still intact.

Col. John Marlowe: Kirby, you tangle with me, I'll have your hide.
Sgt. Maj. Kirby: You're welcome to that too sir, if it's in the line of duty.

Trivia: This movie is based (loosely of course) on an actual Civil War raid led by Colonel Benjamin Grierson. See: "Grierson's Raid: A Cavalry Adventure of the Civil War" by Dee Brown.
