Note 262 — Chapter VIII · THE CENTRAL YEARS OF THE ENGLISH REIGN
Reading edition
For the rest of the Conqueror’s reign, there was peace between Normandy and Brittany, except that in 1086 William, to whom the new count Alan Fergant, the son of Hoel, had refused homage, crossed the border once more and laid siege to Dol. In this siege also he was unsuccessful, and speedily came to terms with Alan, who received Constance, the Conqueror’s daughter, in marriage.
