It almost happened at Ft. Pickens in Pensacola. Lieutenant David Porter tried to open fire on the Confederates, but was prevented from doing so by Captain Meigs who interposed his ship between Porter and the Confederates.
Porter said he almost decided to ram him, but then he decided to stop.
Porter was trying to start the war, and he was acting under direct hand carried and secret orders from Abraham Lincoln.
And yes, none of the other events devolved into fighting.
