Autobiography of Sgt. William Lawrence who fought in the Peninsula and at Waterloo. One of the few literate rankers who wrote down his experiences, fascinating to read about the life of a 'grunt' rather than yet another tome about Wellington or Nay.
Mike Brooke's three books, A Bucket of Sunshine, Follow Me Through and Trials and Errors. Brooke was a pilot during the 60s on Canberras which is the subject of his first book, the second book is his experiences as an instructor and the third his life as a test pilot after ETPS. All written with a very easy and readable style and recommended.
War Beneath The Sea-Peter Padfield. The definitive history of submarine ops during WWII. brilliant and eye opening book. I never knew that U.S. torpedoes simply didn't work for the first part of the war.
