More than 800 men died. Britain suffered the worst loss of life in a naval disaster on home shores. But even to this day little notice has been paid in historical circles to the sinking of HMS Vanguard in 1917. The Vanguard the eighth Royal Navy vessel by that name was an aging ship in need of repair or replacement and had been docked for seven months at the Northern Base on Scapa Flow's north shore. Launched in 1909, the battleship had seen service in the Battle of Jutland, perhaps the greatest sea skirmish of the First World War.
The eighth HMS Vanguard of the British Royal Navy was a St Vincent class battleship, an enhancement of the "Dreadnought" design built by Vickers at Barrow-in-Furness. She was designed and built during the Anglo-German naval arms race and spent her life in the British Home Fleet.
