About The Book

Written with “a cinematic sense of urgency and realism” (Evan Osnos, National Book Award–winning author), this is the first full account of the Casablanca Conference of January 1943, the secret ten-day parlay in Morocco where FDR, Churchill, and their divided high command hammered out a winning strategy at the tipping point of World War II.

The Devils Will Get No Rest is a “vivid and engaging” (Jon Meacham, Pulitzer Prize­­–winning author) 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 visions, 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.

Why We Love It

“Anyone who is interested in World War II will be fascinated to read about a little-known conference where two heads of state and the combined chiefs of staff of the US and the UK gathered in one place for to decide their strategy for defeating Germany and Japan. That should be sufficient, but author James Conroy has uncovered fascinating stories about the famous men who gathered at the Casablanca Conference. Never before or since have so many people essential to a war effort gathered in one place.”

With sophisticated analysis and an eye for the telling detail, this illuminating account of the Casablanca Conference and the war that raged before and after has much to tell us about diplomacy and human nature.”

It is freshly researched, crisply written, and supremely interesting. James Conroy, a richly gifted storyteller, has given us the finest account yet published on this momentously important turning point in world history."
