Cheers for the comments guys, I really appreciate them!!
As for the U-boat, I never did fully explain the background or exact specification, but U-32 is a Type VIIB sub of the 2nd Flottila. I looked on U-boat.net, and U-32 was a VIIA sub from the same flottila, and Buchel actually did command her until Feb 1940. U-32 also has the distinction of sinking the largest ship in the U-baot war, a 42,000 ton liner, Empress of Britain. Unfortunately, U-32 was sunk two days after this. (we'll not be trying to recreate that!)
I'm currently writing the next installment, and we'll hear the aftermath of 'Krystogate'
I was writing the last bit of the previous installment late at night, and I've noticed there are more typos there, so hopefully the next one will be a little more coherent. What can I say, I get so caught up in the action my fingers can't stop rushing over the keyboard!
Anyway, thanks again for all your comments, and I may be able to get the next one up tonight, but I make no promises (probably depends on the Chelsea game

)
Cheers,
Dan Biddle
