Prince Philip of Greece and Denmark was born in Mon Repos on the Greek island of Corfu on 10 June 1921, the only son and fifth and final child of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg. Philip's four elder sisters were Margarita, Theodora, Cecilie, and Sophie. He was baptised into the Greek Orthodox Church. His godparents were Queen Olga of Greece (his paternal grandmother) and the Mayor of Corfu.
After leaving Gordonstoun in 1939, Philip joined the Royal Navy, graduating the next year from the Royal Naval College, Dartmouth, as the best cadet in his course. During the Second World War, he continued to serve in the British forces, while two of his brothers-in-law, Prince Christoph of Hesse and Berthold, Margrave of Baden, fought on the opposing German side. Philip was appointed as a midshipman in January 1940. He spent four months on the battleship HMS Ramillies, protecting convoys of the Australian Expeditionary Force in the Indian Ocean, followed by shorter postings on HMS Kent, on HMS Shropshire and in Ceylon (now Sri Lanka). After the invasion of Greece by Italy in October 1940, he was transferred from the Indian Ocean to the battleship HMS Valiant in the Mediterranean Fleet. On 1 February 1941, he was commissioned as a sub-lieutenant after a series of courses at Portsmouth, in which he gained the top grade in four out of five sections of the qualifying examination. Among other engagements, he was involved in the Battle of Crete, and was mentioned in dispatches for his service during the Battle of Cape Matapan, in which he controlled the battleship's searchlights. He was also awarded the Greek War Cross of Valour. Duties of lesser glory included stoking the boilers of the troop transport ship RMS Empress of Russia. In June 1942, he was appointed to the V and W-class destroyer and flotilla leader HMS Wallace, which was involved in convoy escort tasks on the east coast of Britain, as well as the Allied invasion of Sicily. Promotion to lieutenant followed on 16 July 1942. In October of the same year, he became first lieutenant of HMS Wallace, at 21 years old one of the youngest first lieutenants in the Royal Navy. During the invasion of Sicily, in July 1943, as second in command of HMS Wallace, he saved his ship from a night bomber attack. He devised a plan to launch a raft with smoke floats that successfully distracted the bombers, allowing the ship to slip away unnoticed. In 1944, he moved on to the new destroyer, HMS Whelp, where he saw service with the British Pacific Fleet in the 27th Destroyer Flotilla. He was present in Tokyo Bay when the instrument of Japanese surrender was signed. In January 1946, Philip returned to the United Kingdom on the Whelp, and was posted as an instructor at HMS Royal Arthur, the Petty Officers' School in Corsham, Wiltshire.
