I really felt for the sailors after watching "Das Boot" . I would not have wanted to be stuck in any tin can regardless of who made it. Yeah, they were the enemy, but as submariners, I do have a degree of sympathy for them. The U-boats had a 75% death rate - the highest of any service branch, of any country during WWII. People sometimes ask if I was ever scared about serving in submarines. I can honestly say "never". But, I never had to go to war....
