But the war was going badly, and when Philip was just 18 months old, Greeks revolted against their King. Constantine was forced to abdicate, and Prince Andrew, his wife, four daughters, and infant son were banished. The family escaped on the British naval vessel HMS Calypso, where the infant Philip slept in a cot made from a fruit box. In Paris, an aunt took them in.
While he was at Dartmouth, King George VI and Queen Elizabeth visited, and Philip was asked to escort the King's two daughters, who were his third cousins through Queen Victoria. The king’s older daughter, Elizabeth, who was only 13, began exchanging letter with Philip soon after that.
In 1940, Philip graduated from Dartmouth as the best cadet in his class. He was appointed as a midshipman and served in the Indian Ocean aboard the battleship HMS Ramillies,the HMS Kent, and the HMS Shropshire. After Italy invaded Greece in October, he transferred to the battleship HMS Valiant, which was sailing in the Mediterranean. He fought in the Battle of Crete, and the March, 1941 Battle of Cape Matapan, where the 19-year-old sub-lieutenant was in charge of manning the searchlights used to spot enemy ships. He found two different targets, which his battleship was able to sink, earning himself the Greek War Cross.
By July 1943, Philip was a first lieutenant serving on the destroyer HMS Wallace. During the Allied Invasion of Sicily, the Wallace was targeted by a Luftwaffe bomber who repeatedly attacked. Philip came up with the idea of assembling a wooden raft, which they loaded with smoke pots and launched. Apparently, the German pilot mistook the smoking, flaming raft for the Wallace, which was able to slip away in the dark of night.
After the war ended, Philip asked the King for his daughter's hand in marriage. The King asked that a formal engagement be delayed until Elizabeth's 21st birthday, in April of 1947.
Philip had to relinquish his Greek and Danish royal titles, but he did not give up his position in the Navy. After his marriage on November 20, 1947, he continued to serve, first at the Admiralty, and then at the Navel Staff College in Greenwich. He eventually was promoted to commander, and commanded the frigate HMS Magpie. In 1952, Elizabeth’s father, King George VI died and Elizabeth ascended the throne. Philip then gave up his military career to support his wife, but he continued to hold many honorary titles in the Army, the Navy and the Air Force. He also received pilot training with the RAF, and continued flying until the late 1990s. He remained a warrior at heart throughout his life.
