Wow Great Books

[Salvadoreno]

while i was searchiing for Iron Coffins by hebert warner on the internet i also stumbled upon another book called Iron Coffins which looked rather interesting. Nonficiton (fake) but it was the story of a uboat that patrolled the east coast, was gravely wounded by a aircraft, and limped into the Lousiana Bayou where a tribe secluded itself from the outside world. And the book went on about the experiences of all the men, including some interesting characters and lots of turns and twists. Any1 read this Iron Coffins?
