: 01, 2003

The war at sea was every bit as bitter as the war on land. The battle at Jutland proved inconclusive, but the U-Boat menace threatened Britain as never before. Meanwhile, America entered the war... The evolving naval and intelligence war during the First World War, which saw enemy submarines turn the North Sea into a no-go area. The British responded with a blockade of Europe, and America threw its full support behind the Allies after a deciphered telegram revealed Germany was urging Mexico to attack the United States.
