THOMAS BEAUFORT (d. 1426) held various high offices under Henry IV., and took a leading part in suppressing the rising in the north in 1405. He became chancellor in 141o, but resigned this office in Jan. 1412 and took part in the expedition to France in the same year. In 1416 he became lieutenant of Normandy and was created duke of Exeter ; and returning to England he com pelled the Scots to raise the siege of Roxburgh. Crossing to France in 1418 with reinforcements for Henry V., he took an active part in the subsequent campaign, was made captain of Rouen, and went to the court of France to treat for peace. He was then captured by the French at Bauge, but was released, and returned to England when he heard of the death of Henry V. in Aug. 14 2 2. He was one of Henry's executors, and it is probable that the king entrusted his young son, King Henry VI., to his care. However this may be, Exeter did not take a very prominent part in the government, although he was a member of the council of regency. Having again shared in the French war, the duke died at Greenwich about the end of the year 1426.
