"Maurice III. Seventh Lord. 1321 to 1326.
Maurice succeeded on the death of his father, whom he much resembled in his fondness for all martial exercises and pursuits. He was early accustomed to arms in the Scottish and Welsh wars, held many important military posts and commands, and was summoned to parliament as a peer in the lifetime of his father.
In 1322 he joined with the lords Audely and Mortimer in the rebellion directed against the King's favourites, the two Despencers. Being induced to go with some others to meet the King at Cirencester, on the faith of a safe conduct, he was there treacherously seized and committed to prison in the castle of Wallingford. Berkeley Castle and manors were declared forfeited and were seized by the King, who also laid his hands on all Maurice's plate, jewels, and valuables.
Maurice remained in prison at Wallingford, although several attempts were made to rescue him, until May 1326, when he died there. His remains were at first interred at Wallingford, but were afterwards removed to St. Augustine's at Bristol. He was succeeded by Thomas, his eldest son. "
