Several years ago I saw a movie on TCM. I was not able to see all of it. All I remember of the story was that it was set in the south just before the civil war. Some rich bully had taken over a plantation from someone who had died in debt. He announced that the dead man’s daughter was actually the child of a slave and so was a slave and belonged to him. The girl looked and had been raised as white. The movie was black and white, I think. I don’t remember more. I would appreciate finding out what this movie is.

In color, but otherwise a good fit for your description.
No such thing! Key elements are: the strike team (should I say Spetznatz?) in a very dangerous location (I should say Earth??); doomed to wait for rescue only for half of them (lack of breath clean air?); they draw lots and further fight (I should say with respect) each other to death of half of them
was Clark Gable in the movie? If yes check out Band of Angels (1957)
