The Battle of the Atlantic : the war against Allied shipping, 1939-1945 /Peter Gretton

"Vice-Admiral Sir Peter Gretton - a distingushed Royal Navy escort commander - has written an authorative history of the war he fought. The subjects range from merchant shipping to intelligence, the role of Operational Research, the battle for maritime air in Whitehall, the contribution of the Royal Canadian Navy, and the strategies employed by the convoys to defeat the 'wolf pack' system of attack by the U-boats - interspersed with narrative chapters which illustrate the points he has been making. Above all, he describes the courage of the Allied merchant seamen who carried out their dangerous work with devotion."--Provided by the publisher.
