A World War II merchant seaman, John Bunker takes a thorough look at the American merchant marines' significant contributions to the war effort. There are plenty of fascinating facts about their extensive supply operations, but the focus of the book is on the men and their often-heroic actions. Bunker draws from his own experiences to describe the action at sea and also includes the personal stories of many other civilian participants. It is a engaging portrayal of the courage, bravery, and ingenuity demonstrated by these merchant seamen. All theaters of operation using U.S. merchant ships are covered, and in addition, Bunker provides information on events before the country entered the war when efforts were being made to build more ships and to recruit the men necessary to crew the huge fleet.
