Other members of the royal family were similarly involved. Prince Albert, Duke of York (later George VI), was commissioned in the Royal Navy and saw action as a turret officer aboard HMS Collingwood at the battle of Jutland but saw no further action in the war, largely because of ill health.[41] Princess Mary, the King's only daughter, visited hospitals and welfare organisations with her mother, assisting with projects to give comfort to British servicemen and assistance to their families. One of these projects was Princess Mary's Christmas Gift Fund, through which £162,000 worth of gifts was sent to all British soldiers and sailors for Christmas 1914.[42] She took an active role in promoting the Girl Guide movement, the Voluntary Aid Detachment (VAD), the Land Girls and in 1918, she took a nursing course and went to work at Great Ormond Street Hospital.[43]
