The remarkable photograph from 1937 shows Prince Philip, then just 16, in a funeral procession for his older sister Cecile, who was killed in an air crash.
The young prince is flanked by grieving relatives, all wearing distinctive Nazi uniforms. One is clad in the uniform of the Brownshirts; another wears full SS regalia. The street in Darmstadt, near Frankfurt, is lined with crowds – many giving the ‘Heil Hitler’ salute.
In another extraordinary photograph Prince Philip’s youngest sister Sophie – elegantly dressed with a fur hanging on the back of her chair – is seen sitting opposite Hitler at the wedding of Luftwaffe commander Hermann Goering and his bride Emmy.
