In 1991, a badass named John Chatterton found a German U-boat where none should be.  He then hooked up with many other badasses to dive it and identify it.  Some of the badasses encountered existence failure, while others' survival was Hand-of-God like.  It also turns out that history doesn't like itself getting rewritten much. Chatterton gets help from another diver, Richie Kohler.  The two  fight like little girls in the beginning, but end up snuggling like grown up girl lesbians by the end.  They have since gone on to cable in the form of "Deep Sea Detectives", a great show if you're interested in shipwrecks, which you should be.

  Robert Kurson turns a good story into a burn-through-the-book-in-two-days great story.

  You'll feel like a pussy next to these guys, and chances are mighty good you are, so just be happy they don't want to steal your girl, and read this book right now.

FUN HISTORY FACT: A radio master, or senior radioman, in the German U-boat force was known as a 'Funkmeister.' I know! 

U-boat commander :"Funkmeister Bishop!" Me:"Ja, mein Commandant?"
UBC:"Zet us up ze bomb, perhaps zom Grandmaster Flash...Mach schnell!"
Me:"Jawol, mein oberfuher!  Däs boot vill be jumpink !"

BONUS ENDORSEMENT: -CLIVE CUSSLER liked it, and he's so badass he found and raised (with some assistance to be sure) the HUNLEY, a rebel civil war sub that sunk a ship before disappearing into the briny blue.  In your face,
Yankees!
Now go study some history, since you don't seem interested in making any.  Weak.

Tangentially Contextual:

Maat Frenssen:"Why?"

Maat Pilgrim:"Because I have some up my ass.  We can tie them together."
