In this third volume of a six-volume series, Winston Churchill draws upon thousands of personal memoranda, war correspondence, and internal government memos to describe the full entry of the US into World War II--adding considerable strength to British military operations and morale. While America had contributed to the British war effort before, primarily through the "Lend-Lease" program providing material support to Britain and later to Russia, it was Churchill who finally persuaded an isolationist US Congress to fully join the cause.

This account not only documents historical events with thrilling immediacy--it also gives intimate insight into Churchill's state of mind as a military leader. With the US on Britain's side, Churchill's certainty of success stayed with him throughout the war--and made him the indomitable leader history remembers.
