Of the 1,155 U-boats Germany sent into combat, 725 had been sunk in the longest battle of the war. Lasting nearly six years, over 35,000 German sailors had put to sea, with 28,744 never returning – a death rate of 82 percent, the highest casualty rate of any armed forces of any conflict in the history of modern war.
