Have you read the diaries of Lewis and Clark?
I read once that Lewis shot Clark by accident. Surface wound. Did you read anything about that?
I remember that one, but it was Lewis who got shot by one of the men:

jus opposite to the birnt hills there happened to be a herd of Elk on a thick willow bar and . . . I determined to land and kill some of them accordingly we put too and I went out with Cruzatte only. we fired on the Elk I killed one and he wounded another, we reloaded our guns and took different routs through the thick willows in pursuit of the Elk; I was in the act of firing on the Elk a second time when a ball struck my left thye about an inch below my hip joint, missing the bone it passed through the left thye and cut the thickness of the bullet across the hinder part of te right thye; the stroke was very severe . . .
I do not beleive that the fellow did it intentionally but after finding that he had shot me was anxious to conceal his knowledge of having done so.
the ball had lodged in my breeches which I knew to be the ball of the short rifles such as that he had, and there being no person out with me but him and no indians that we could discover I have no doubt in my own mind of his having shot me. with the assistance of Sergt. Gass I took off my cloaths and dressed my wounds myself as well as I could, introducing tents of patent int into the ball holes, the wounds blead considerably but I was hapy to find that it had touched neither bone nor artery.
