In 1942, America's most crucial mission was to provide arms and supplies to our English and Russian allies. Theodore Taylor, who served in the merchant marines in World War II, tells the tragic tale of a convoy of 33 ships that sailed from Iceland to Russia in an effort to bring the Soviets needed tanks, trucks, airplanes, and ammunition. In vivid detail, Taylor follows one of the ships through the frigid waters of the Arctic as it battles Nazi bombers and submarines—and as its crew helplessly watches many of their companion ships perish in the mad dash to safe port.
