Prince Philip's grief after his sister's tragic death was detailed in his school reports, a royal expert has revealed.

The late Duke of Edinburgh, who died aged 99 at Windsor Castle last Friday, experienced a gutwrenching loss in his youth when his 'favorite' sibling was killed in a plane crash in 1937. 

Princess Cecilie of Denmark and Greece died while flying from Germany to London for a wedding after the aircraft crashed into a factory building and blew up in flames. Everybody on board was killed, including the royal's husband and her two sons. At the time, 16-year-old Prince Philip was at Gordonstoun, a private boarding school in Scotland. Far away from any family members, he was informed of the horrific news by his principal, Kurt Hahn. 

The headmaster recalled that Prince Philip maintained his composure at the time, revealing that 'his sorrow was that of a man.' However, recently unearthed sources have shown that the teenage aristocrat was torn apart by the devastating loss.

"A report came out a couple of days ago from the Gordonstoun archives and in it Kurt Hahn describes how very, very distraught Philip was, and this is a man who doesn't show his emotion," said Ingrid Seward, Editor-in-Chief of Majesty Magazine. "He kept a little piece of wood from the aeroplane. It was a real tragedy.”

Prince Philip attended the funeral of his sister and her family in Germany, which was under the reign of Adolf Hitler at the time. He was pictured flanked by Nazi officers as he followed the procession through the streets of Darmstadt, where Cecilie had lived with her husband and two sons, as well as her one surviving daughter. 

Prince Philip graduated from Gordonstoun a year later and enrolled in the Royal Naval College, where he would meet the future Queen of England, Princess Elizabeth.
