personally, i came across uboats due to the film "das boot", as i watched the tv mini series in 1985. after that i read the book "iron coffins" and got addicted to this topic.
cant say, what it really is about the boats. but its a very special weapon and there are very special crews in it. you are all alone with 50 men in this steel cigar. far away from home, beneath your boat, just hundrets or thousands meters of water. and above also just water. its different to normal ships on surface. the small room you have, no personal area for yourself, no daylight for most of the crew...and for all of these reasons, a great and uncomparable comradeship.
its simply fascinating...
