According to the chronicler Orderic Vitalis, the crew asked [William Adelin, Henry I’s heir] for wine and he supplied it to them in great abundance. By the time the ship was ready to leave there were about 300 people on board, although some, including the future king Stephen of Blois, had disembarked due to the excessive drinking before the ship sailed. Orderic attributes this to a sudden bout of diarrhoea.
FitzStephen was ordered by the revellers to overtake the king’s ship, which had already sailed. The White Ship was fast, of the best construction and had recently been fitted with new materials, which made the captain and crew confident they could reach England first. However, when it set forth in the dark, its port side struck the submerged Quilleboeuf Rock, and the ship quickly capsized.

A result of William Adelin’s death was the period eighteen years later known as the Anarchy. The White Ship disaster had left Henry I with only one legitimate child, a second daughter named Matilda.
Swallowed by the waves, occosionally. Without heirs.
