Red Mountain is a 1951 American Western film directed by William Dieterle and starring Alan Ladd, Lizabeth Scott, Arthur Kennedy and John Ireland, set in the last days of the US Civil War.

Colorado, 1865: a gold assayer is killed and Lane Waldron is seen leaving, so a posse goes after him and, when he is caught, turns into a lynch mob.

The rescuer turns out to be Brett Sherwood, a Confederate captain from the Civil War.

Chris and Brett discus the war and he finds that she has different loyalties from Lane, hating the rebels and General William Quantrill in particular for killing her family.

As he leaves to go for a doctor, Quantrill and his raiders turn up, taking Lane and Chris captive.

Brett and Chris return with a doctor who operates on Lane, saving both his life and leg.
