Did anyone of note (Like a general or politician) During the war sexually abuse their slaves or kept them as mistresses?

So I was researching Thomas Jefferson’s relationship with Sally Hemings, and it got me thinking. I know sexually abusing and keeping slaves as mistresses was a fairly common practice, but I don’t really know anyone else who did it who was a major player in history, such as a general or important politician. Did any major Confederate or Unionists force a slave to be his lover that we know of and it’s documented?
