The fight consisted of me putting a bunch of deck gun shells into him and not doing much, sunk his friend who came to help, then got tired of shooting and I styarted ramming. 19 knots, right into his side!
Now is the time to add another weapon to the anti-destroyer arsenal, we have deck guns, torpedoes and ramming, and now, tipping. I took no damage ramming him by the way, just rolled him over.
Edit: This is wrong, I just didn't notice I went from 70% HI to 33%,
