How far did personality affect the grand strategy of the Second World War? Award-winning historian Andrew Roberts lays bare the four political masters and military commanders of the Western Allies - Franklin Roosevelt, Winston Churchill, General George C. Marshall and Lord Alanbrooke - between Pearl Harbour and VE-Day, coming to a number of startling conclusions. Employing verbatim accounts of Churchill's War Cabinet meetings never before reporduced in book form, as well as using the private papers of sixty-seven contemporaries of the four men, the inside story is told of the great war wartime conferences, explaining why and how the Allies attacked when and where they did.The two masters (Churchill and Roosevelt) and two commanders (Marshall and Alanbrooke) were strong-willed and tough-minded and each was certain that he knew best how to win the war. Yet in order to get their strategies adopted, each needed to persuade at least two of the other three, and certainly not be so outmanouvered that he ever found himself in a minority of one. Roberts reveals the dynamic behind the collective decisions upon which the lives of millions ultimately depended.
