The seventh volume of the acclaimed, official biography: "An engrossing history of Churchill's crucial role in the grand alliance of World War II" ( Los Angeles Times).   This seventh volume in the epic, multivolume biography of Winston S. Churchill takes up the story of "Churchill's War" with the Japanese attack on Pearl Harbor on December 7, 1941, and carries it on to the triumph of V-E Day, May 8, 1945, the end of the war in Europe.   Acclaimed historian Martin Gilbert charts Churchill's course through the storms of Anglo-American and Anglo-Soviet rivalry, and between the conflicting ambitions of other forces embattled against the common enemy: between General de Gaulle, his compatriots in France, and the French Empire; between Tito and other Yugoslav leaders; between the Greek Communists and monarchists; between the Polish government exiled in London and the Soviet-controlled "Lublin" Poles.   Amid all these volatile concerns, Churchill had to find the path of prudence, of British national interest, and, above all, of the earliest possible victory over Nazism. In doing so he was guided by the most secret sources of British Intelligence: the daily interception of the messages of the German High Command. These pages reveal, as never before, the links between this secret information and the resulting moves and successes achieved by the Allies.   "A milestone, a monument, a magisterial achievement . . . rightly regarded as the most comprehensive life ever written of any age." —Andrew Roberts, historian and author of The Storm of War   "The most scholarly study of Churchill in war and peace ever written." —Herbert Mitgang, The New York Times
