On the night of July 30, 1945, the Navy cruiser USS Indianapolis was torpedoed by a Japanese sub, sending 900 men into the black, churning waters of the Pacific. What happened next was a nightmarish battle for survival. Injured, adrift, clinging to each other and their waterlogged life rafts, the men watched in horror as their crewmates fell victim to catastrophic injuries, exposure, hallucinations, and relentless shark attacks. Worst of all, their last radio S.O.S. had been disregarded by the Navy as a possible prank. When help finally arrived an astonishing five days later, only 317 of the ship's crew were still alive. Meticulously researched, including eyewitness reports from USS Indianapolis survivors, In Harm's Way recounts with frightening accuracy those five harrowing days at sea, and gives readers a moving, unforgettable account of the worst naval disaster at sea in U.S. history.
