Henry VI, Part 4: The Morning's War - S1.E12

After the murder of Humphrey of Gloucester, the Duke of Suffolk, banished for his part in the crime, was executed by pirates during his journey into exile. Soon afterwards a murderous rabble from Kent invaded London at the instigation of the Duke of York. Their rebellion was defeated, and the leader Jack Cade killed. The armies of the Duke of York and Queen Margaret have recently fought a battle at St. Albans. York and his sons won the day; but Margaret managed to escape, taking King Henry with her.
