This is the story of the Life and Times of one of the Royal Navy's greatest fighting men. They state that only one other received 4 D.S.O.'s and a C.B. to cap them. "Quartermaster's Comment":- "Johnnie Walker" was the Navy's greatest U Boat killer of the attle of the Atlantic and did more than any other individual to help win that battle. A Superlative read and a MUST for anyone keen on matters Naval.
