He died on the 12th July 1450 near Lewes. In response to grievances, Cade led an army of as many as 5,000 against London, causing the King to flee to Warwickshire. After taking and looting London, the rebels were defeated in a battle at London Bridge and scattered. Promised pardons and reforms, many of the rebels were instead declared traitors, and Cade was killed in a small skirmish on 12th July 1450.
