This is the story of how, despite all odds, the Royal Navy helped Britain survive during the critical times of the Battle of the Atlantic, the Siege of Malta, the convoys to northern Russia, and the D-Day landings. It credits the dogged determination of British seafarers in the early part of the war for causing the demise of the German big-ship fleet, leaving the U-boat and E-boat to fight Hitler's war at sea. The book also explains why the British could not play the part they wished in the Eastern and Pacific war.
