Submarine as convoy escort?

[siber]

I've seen three convoys with surfaced subs escorting, and one of those had HMS Rodney stuffed in the middle!

I'm sure you can guess how I used my last three torps! The first two went off to hole her broadside and knock off her propellers. This stopped her, but I got pounced on by escort DDs. But knowing she was crippled (I admit - used external camera), I went deep and stayed there for half an hour. The only problem was that I only had 1 torp remaining in my stern tube. Thinking this would have to suffice, I set it to run at 12m and enabled the magnetic pistol. Upon firing, it ran straight for the 500m between us and sailed clean under without detonating... I couldn't believe my eyes!!!

I wasn't brave enough to surface and get the deck crew onto the 88mm while facing the huge guns on Rodney. The crew would probably have mutinied if I'd even suggested it... I skulked off submerged to return to base...
