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, [her husband] Richard (age 26), earl of Chester, [her brother-in-law] 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 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.
