World War II and its attendant horrors arguably began in the British policy of appeasement of the Nazi rise to power between the First and Second World Wars.
In this compelling telling, Martin Gilbert walks the reader through several decades of behavior that, in retrospect, is hard to accept. Gilbert’s incisive focus on primary sources uncovers the real reasons for the appeasement policy, from the search for a just peace to attempts to avoid another war at all costs—illuminating the historical underpinnings of a fatally flawed policy, and its tragic consequences for the Jewish people.
The book also contains a chronology of appeasement policy as well as five specially drawn maps and five appendices—including a transcript of British statesman and politician David Lloyd George's conversation with Hitler at Berchtesgaden in 1936.

Covering the years 1917 to 1922, Martin Gilbert’s fascinating account carefully traces Churchill’s wide-ranging activities and shows how, by his persuasive oratory, administrative skill, and masterful contributions to Cabinet discussions, Churchill regained, only a few years after the disaster of the Dardanelles, a leading position in British political life.
There are many dramatic and controversial episodes: the German breakthrough on the Western Front in March 1918, the anti-Bolshevik intervention in 1919, negotiating the Irish Treaty, consolidating the Jewish National Home in Palestine, and the Chanak crisis with Turkey. In all these, and many other events, Churchill’s leading role is explained and illuminated in Martin Gilbert’s precise, masterful style.
The Churchill who emerges from these pages is a complex, gifted, energetic, troubled man who made a forceful impact on his contemporaries; a man whose remarkable skills were admired by his colleagues, but who often angered—even maddened—them by what he said and did.
In a moving final chapter, covering a period when Churchill was without a seat in Parliament for the first time since 1900, Martin Gilbert brilliantly draws together the many strands of a time in Churchill’s life when his political triumphs were overshadowed by personal sorrows, by his increasingly somber reflections on the backward march of nations and society, and by his stark forecasts of dangers to come.

This volume 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.
Within a week of Pearl Harbor, Hitler and Mussolini had declared war on the United States. Thus Churchill, Roosevelt, and Stalin were now leaders of the great alliance that held the assurance of ultimate victory. But in 1942, the first year of the new alliance, the war went badly on every front, and Churchill faced serious criticism at home.
In this volume, Martin Gilbert charts Churchill’s tortuous course through the storms of Anglo-American and Anglo-Soviet suspicion and rivalry and between the clashing priorities and ambitions of other forces embattled against the common enemy: between General de Gaulle and 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 cares and dangers Churchill had to find the course 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.
