A character-driven account of the Casablanca Conference of January 1943, an Anglo-American clash over military strategy that produced a winning plan when World War II could have gone either way. Churchill called it the most important Allied conclave of the war. Until now, it has never been explored in a full-length book. In a secret, no-holds-barred, ten-day debate in a Moroccan warzone, protected by British marines and elite American troops, Franklin Roosevelt, Winston Churchill, Charles de Gaulle, George C. Marshall, Dwight D. Eisenhower, George S. Patton Jr., Sir Alan Brooke, Lord Louis Mountbatten, Sir Harold Alexander, and their military peers questioned each other's competence, doubted each other's vision, and argued their way through choices that could win or lose the war. You will be treated to a master class in strategy by the legendary statesmen, generals, and admirals who overcame their differences, transformed their alliance from a necessity to a bond, forged a war-winning plan, and glimpsed the postwar world
