Along with his brother and nephew, he took part in
Henry IV's deposition of
Richard II. He is said to have broken the staff of office symbolizing his position as Richard II's steward when declaring for the revolt. Later, in turn, he took part in the Percies' own subsequent rebellion against King Henry IV. He is said to have negotiated with Henry IV before the Battle of Shrewsbury and then misrepresented King Henry's offer for a settlement to persuade his nephew Henry "Hotspur" to reject the offer and fight the battle. ==Capture and execution==
