Task: Question Generation
Input (English): Fort Bravo is a Union prison camp run by a strict Captain Roper (William Holden). A pretty woman named Carla Forester (Eleanor Parker) shows up to help free the prisoners, especially Confederate Captain John Marsh (John Forsythe). Roper falls in love with her (and she with him), so he has an additional motive to recapture the escapees. He does just that, but on the way back to the fort, they are attacked by fierce Mescalero Indians who are hostile to both sides and trapped in a shallow exposed depression. Roper frees and arms his prisoners, but even then, it looks like the Indians will wipe them out. Bailey (John Lupton) escapes to call for help. One by one, they are killed, including Campbell (William Demarest), Young (William Campbell), and the American Indian guide. Marsh and Lieutenant Beecher (Richard Anderson) are wounded. The next morning, to try to save Carla, Roper makes it look like he is the only one left alive and walks out in plain view. He is wounded, but the cavalry comes to the rescue just in time. Roper thanks Bailey for coming with help, while Marsh dies after smiling at Bailey.
Output (English): Question: Who plays Captain John Marsh?, Answer: John Forsythe
