Men in War(1957)
In Korea, on 6 September 1950, Lieutenant Benson's platoon finds itself isolated in enemy-held territory after a retreat. Soon they are joined by Sergeant Montana, whose overriding concern is caring for his catatonic colonel. Benson and Montana can't stand each other, but together they must get the survivors to Hill 465, where they hope the division is waiting. It's a long, harrowing march, fraught with all the dangers the elusive enemy can summon.
