Note 81 — Chapter III · INDEPENDENT RULE, 1087-95
Reading edition
The date of the treaty is not given specifically, but according to Ordericus Vitalis (iii, p. 378) William and Robert, after they had made peace, besieged Henry at Mont-Saint-Michel for two weeks in the middle of Lent—according to Florence of Worcester (ii, p. 27), during the whole of Lent. The treaty, therefore, could hardly have been concluded later than the end of February.
