Which military leader was known for sending troops to retreat into swamps after a quick attack

john paul johns
francis marion
ethan allen
john burgoyne

The answer is not Ethan Allen I'm pretty sure. I believe the correct answer is Francis Marion because he was given the nickname "Swamp Fox" because him and his men attacked swiftly, and then vanished into the swamps before reinforcements of the other party could arrive. But uh I could be wrong (:

answer; did not understand that the act was wrong because she/he was suffering from a mental illness;
