How Lady Louise is carrying on the late Queen's legacy: Duke and Duchess of Edinburgh's daughter has inherited key traits from her grandmother and Prince Philip, says expert Queen Elizabeth was just 13 years old when she and her sister Princess Margaret were evacuated to Windsor Castle when WWII broke out in 1939.
And royal expert, Richard Fitzwilliams, believes that Lady Louise Windsor could have what it takes to keep Queen Elizabeth and Prince Philip's legacy alive, as she also took up her grandfather's hobby of carriage driving before he died.
Three years later, she carried out her first official duty, inspecting troops during a parade at Windsor Castle and it wasn't long before she joined the women's arm of the British Army at 18 and became the first female member of the royal family to serve in the armed forces.
And there is one young royal whose personality echoes some of the core values that Elizabeth stood for; her beloved granddaughter, Lady Louise Windsor.
In photos shared on social media, she looked to be in high spirits as she donned military gear and covered her face in camo paint while taking part in training.
