The Last Enemy - Paperback

Hillary joined the Royal Air Force at the start of the Second World War as a university undergraduate. Its text details his experiences as a Spitfire pilot during the Battle of Britain, during which he was shot down in action, sustaining severe injuries.

He wrote the book in New York City while still recuperating from his wounds during a propaganda publicity tour in the United States in 1941 organized by the British Government to attempt to raise support for the Allied cause and the U.S.A.'s entry into the war. However, he was not allowed to appear in public personally, owing to concerns that his severely facially scarred appearance might prove counter-productive, and his work was confined to newspaper interviews and radio broadcasts.

Hillary was killed just 7 months after writing this book in his 24th year while piloting an aircraft in a training accident in 1943.
