Reminds me of this Irishwoman who joined the British army in the late 1600s and managed to remain disguised as a man until she was receiving treatment after being wounded -- but only for the second time!:

It's so amazing that it's hard to believe. For example:

"She was so successful at passing herself off as a man that a prostitute claimed she was the father of her child. Rather than give proof that this was impossible, [she] paid child support to the woman."
