Shadow divers - Robert Kurson

February 1945. The war is almost over and Britain and America rule the waves. Sixty young Nazi soldiers are stranded underwater in U-Boat U-869 with barely enough fuel to make it home. The commander must decide whether to carry on to America and risk death in the pursuit of glory, or to admit defeat and return home. He decides to risk it.

September 1991. Two deep-sea wreck divers receive a tip-off from a local fisherman about a site off the New Jersey coast. What they discover defies belief: a Nazi U-boat, 230 feet underwater. The recommended limit for diving is 130 feet, but John Chatterton and Richie Kohler know that if they don't take the risk, the mystery of the wreck will remain unsolved.

SHADOW DIVERS is the extraordinary story of the six-year quest for Hitler's lost sub. In the attempt to identify the sunken U-boat and its crew, the team teach themselves German, turn back fanatics and conspiracy theorists, and piece together an incredible story. In between, they make some of the most daring and dangerous scuba dives ever attempted. This is a gripping and compellingly readable account of human courage in the face of remarkable odds.
