I had installed GWX and figured I'd get some training in before starting a career.
During the convoy attack training mission, the Destroyer at the front of the convoy detected me right after I'd fired my first group of torpedoes.
I had driven submerged into the heart of the convoy, and when he started dropping depth charges on me, one of them detonated near the surface causing damage to a merchant ship I was hiding beneath.
Apparently that counted as an attack on a friendly unit, and the ASW Trawler in the rear of the convoy came steaming ahead firing his guns on the Destroyer!
After he hit the Destroyer a couple times, the Destroyer returned fire and they sank each other!
Needless to say, I drove to the surface and sank all the merchants with my deck gun and stern tubes. Easiest convoy attack I've ever had
