World War II was only a few hours old when the Battle of the Atlantic - the longest campaign of the Second World War and the longest, most complex submarine war in history - began with the sinking of an armed merchant cruiser by the German submarine U30. This book charts the fascinating development of U-boat capacities and the techniques used by the Allies to try to arrest the power of this secretive force.
