Florence of Worcester Continuation. 1120 and 1121. Shipwreck of king Henry's children. Henry, king of England, having successfully accomplished all his designs, returned from Normandy to England. His son William (age 16), hastening to follow him, embarked in company with a great number of nobles, knights, women, and boys. Having left the harbour and put out to sea, encouraged by the extraordinary calmness of the weather, shortly afterwards the ship in which they were sailing struck on a rock and was wrecked, and all on board were swallowed up by the waves, except one churl, who, as it is reported, was not worthy of being named, but by the wonderful mercy of God, escaped alive. Of those who perished, those of highest rank were, William, the king's son, Richard (age 26), earl of Chester, [his half-brother] Othiel, his brother, William Bigod (age 27), Geoffrey Riddel, Walter d'Evereux, Geoffrey, archdeacon of Hereford, the king's daughter, the countess of Perche, the king's niece, the [his wife] countess of Chester, and many more who are omitted for brevity's sake. This disaster horrified and distressed the mind of the king, who reached England after a safe voyage, and of all who heard of it, and struck them with awe at the mysterious decrees of a just God.
Note 1. Ordericus Vitalis, in his twelfth book, c. xxv., gives a particular account of the shipwreck of the Blanche Nef; which is also mentioned, with more or less detail, by Huntingdon, Malmesbury, and other chroniclers.
On 25 Nov 1120 the White Ship left Barfleur, Basse Normandie, with a party of young Normans. King Henry I "Beauclerc" England (age 52) had left earlier on another ship. A mile out the White Ship foundered on a submerged rock.

And in this expedition were drowned the king's (age 52) two sons, William (age 17) and Richard (age 19), and Richard, Earl of Chester (age 26), and [his half-brother] Ottuel his brother, and very many of the king's (age 52) household, stewards, and chamberlains, and butlers, and men of various abodes; and with them a countless multidude of very incomparable folk besides. Sore was their death to their friends in a twofold respect: one, that they so suddenly lost this life; the other, that few of their bodies were found anywhere afterwards.
