The White Ship (French: la Blanche-Nef) was a vessel that sank in the English Channel near the Normandy coast off Barfleur, on 25 November 1120. Only one of those aboard survived. Those who drowned included William Adelin, the only surviving legitimate son and heir of King Henry I of England. William Adelin’s death led to a succession crisis and a period of civil war in England known as The Anarchy.
The only known survivor was a butcher from Rouen. He was wearing thick ramskins that saved him from exposure, and was picked up by fishermen the next morning.
