Kinda related, but not really...I was on google earth last night and one of the things they have you can look at are shipwrecks, including U-boats. There's a little bit of info about what U-boat it is, when it was sunk and who dun it. But no mention of any CAP sinkings.
See pages 428-432 about CAP and the U-boat kill "claims" in the article.
