For me it was back before the full release was created I was doing the u48 campaign and had a free roam Patrol. I had every conning Tower researched and so was fully decked out with the two heavy machine guns in the quad 20 mil as well as keeping my 88 are you boat sighted a convoy and gave me its location after Chasing the U-Boat for a couple hours I eventually said screw it use my own hydrophone to find the Convoy and raced straight towards it accidentally got too far directly behind the Convoy and Triggered the escorts i dipped below the surface and slipped right under them surfaced after they got out of sight and raced back towards the Convoy. Went up alongside the Convoy planning on turning into torpedo it or engage with the 88 I decided to turn straight in and engage with the 88 however I failed to realize until it was too late that there was one final escort in the Convoy an aircraft carrier panicking knowing I'd be torn to sreeds if I tried to dive by either the aircraft or the carrier itself I decided to go out guns of Blazing engaging the carrier with my 88 well the other crew members engaged the aircraft with the anti-aircraft guns and a half hour in game gun fight I somehow managed to sink the carrier and down roughly 15 planes always wanting to take a bunch of deck gun ammunition with me I had a few Stacks to spare repairing the damage and healing crew members I decided to go after Merchant ships. By morning the next day I had used up all of my deck gun ammunition all but six Torpedoes in the front tubes and even depleted my anti-aircraft guns ammunitions and there were still two Merchants left my crew was so exhausted I couldn't get a proper torpedo calculation wasted two on one merchant ship finally sinking it with the third my crew was to exhausted to reload so after using my final torpedo to Cripple it and then sending a dud I had to move out of combat range to load the final torpedo again before moving back in and sinking the merchant ship I had no spare parts left and only two Med kits by the time I got back to Port. Surprisingly I only lost one sailor my captain ended up getting the knights cross with swords oakleaf's and diamonds don't remember if I got two Awards with that or not but a total of seven Merchant ships roughly just under 70,000 tons as well as an illustrious class carrier all in one Patrol I'm fairly certain the other uboat got sunk though though I can't remember for sure and while the game didn't register the aircraft is shot down I know at least 15 of the fairy fulmers from the carrier fell to my AA guns so I racked them on with my kills.
