British and Australian sailors, soldiers, and airmen are marched from the prisoner of war camps in Burma and Thailand, where they were forced to construct railroads, to Saigon. There they are to be loaded onto freighters bound for Japan where they will serve as forced laborers. But first they have to survive the gauntlet of American submarines that are sinking Japanese shipping in the South China Sea. Two ships, which aren't marked as hospital ships, are torpedoed by the submarines. Will the survivors be picked up by Japanese ships and sent to Japan? Will they be rescued by the American submarines? While they are adrift they have to survive the sun, salt water, sharks, and oil slicks.
The authors were able to track down & interview many of the survivors as well as American submarine crew members. This book is a quick and enjoyable read.
