The Duke of Edinburgh enjoyed a long and successful career in the Royal Navy. Prince Philip rose through the ranks and even became Commander Mountbatten of the HMS Magpie before choosing duty over service as Princess Elizabeth became Queen. He still enjoyed a close association with the Navy and even carried out his last official engagement in the company of the Royal Marines. Report by Fullerg.
