East Coast S-Boote Primary Sources

I was looking for information about Hunt class destroyer escorts this morning, when I bumped into this intelligence report from 1943, which was based on interrogation of the survivors of S-71 after she was rammed and sunk by HMS Garth. It's much more than an account of the action though, with copious detail of the 6th S-Boote flotilla and Kriegsmarine coastal warfare tactics in general. It's a gold mine for anyone interested in historical scenarios and also very useful for campaign background material. You can find scans and transcripts of the whole document here:
