Peter Thump is Horner’s apprentice.
Hearing his master claim that the Duke of York is the rightful King, he takes the opportunity to denounce his master. He is a coward, and convinced he will be killed in the fight with Horner. He refuses the drinks pressed upon him by the other apprentices, and is therefore able to best his very drunken master, killing him. He is a simple man, but kind, with many friends.
