Front Cover
Barnes & Noble Publishing, 2001 - World War, 1939-1945 - 336 pages
"Among the greatest dramas of World War II were those that challenged human intelligence. As American engineers and physicists probed the potential of the atom, Polish, British, and American cryptologists struggled feverishly to break the German U-boat codes that were helping Nazi submarine wolfpacks tear at the Allied lifeline between Britain and America. Seizing the Enigma tells the action-packed story of how captures at sea enabled the Allies to crack these codes and prevail in the perilous game of hide-and-seek above and below the waves."--Jacket.
