An engrossing memoir that uncovers the turning point of the Battle of the Atlantic against the U-boat menace. Perfect for fans of Ian Toll, Jonathan Dimbleby or C. S. Forrester’s Greyhound. Vice Admiral Sir Peter Gretton’s book is a brilliant account of his career in the navy through World War Two: fighting in the Second Battle of the Narvik, guarding convoys in the Mediterranean and the North Atlantic, before being placed in charge of Escort Group B7, which he described as “the finest job in the Navy for a new commander”.
