I thank all the uboat enthusiasts for their detailed explanations about sanitary facilities and trials that the officers and crew were subjected to in their daily lives for months at a time. I now know why the time between patrols was as long as it was - it took weeks to just air the boat out. WOW! What a way to fight a war! Foxholes were bad enough but not to the degree of being in a sub. Thanks again for clearing up my knowledge on the subject. I fell in a cesspool once when I was a kid - stank really bad - after dad fished me out. But, it was all over after a good bath! I can\'t even imagine the odorific experience of a ubootsman.
