The Second World War is a history of the period from the end of the First World War to July 1945, written by Winston Churchill. It was largely responsible for his being awarded the Nobel Prize for Literature in 1953. Churchill labelled the “moral of the work” as follows: “In War: Resolution, In Defeat: Defiance, In Victory: Magnanimity, In Peace: Goodwill”.
Churchill wrote the book, with a team of assistants, using both his own notes and privileged access to official documents while still working as a politician; the text was vetted by the Cabinet Secretary. Churchill was largely fair in his treatment, but wrote the history from his personal point of view. He was unable to reveal all the facts, as some, such as the use of Ultra electronic intelligence, had to remain secret. From a historical point of view the book is therefore an incomplete memoir by a leading participant in the direction of the war.
The book was a major commercial success in Britain and the United States. The first edition appeared in six volumes; later editions appeared in twelve and four volumes, and there is also a single-volume abridged version.
