After the fall of France in June 1940, only Britain stood between Hitler and total victory. Desperate for allies, Winston Churchill did everything he could to bring the United States into the conflict, drive the Soviet Union and Nazi Germany apart and persuade neutral countries to resist German domination.

By 1942, after the German invasion of Russia and the Japanese attack on Pearl Harbor, the British-Soviet-American alliance was in place. Yet it was an improbable and incongruous coalition, divided by ideology and politics and riven with mistrust and deceit. Churchill, Roosevelt and Stalin were partners in the fight to defeat Hitler, yet they were also rivals who disagreed on strategy, imperialism and the future of liberated Europe.

Allies at War is a fast-paced, narrative history, based on material drawn from over a hundred archives. Using vivid, first-hand accounts and unpublished diaries, we enter the rooms where the critical decisions were made, revealing the political drama behind the military events.
Ambitious and compelling, Allies at War offers a fresh perspective on the Second World War and the origins of the Cold War.
