Searching for a story

I'm looking for a story that has nothing to do with anything that has appeared here on BCTS or the other websites, but I am hoping that someone is well-read enough to have heard of it.

The scene was set during World War II or in the Far East during a conflict of some sort. A group of prisoners are lined up and told that every third man will be killed. When they choose the main character, she removes her hat to show that she is not a man at all.

Does this sound familiar to anyone?

Thanks.
