The Duke of Somerset, first of the Yorkist and then of the Lancastrian party, is the son of the Somerset of Henry VI, Part Two, whose head is carried in by Richard in the first scene.
Though he appears won over to the Yorkist cause, he follows Clarence when the latter defects to Warwick. Guessing that there is more fighting to come, he convinces Oxford that they should send young Richmond abroad to keep him from harm’s way. Somewhat downcast by Warwick’s death and the Queen’s late arrival to battle, he is revived by Prince Edward’s valiant speech. Captured in battle, he has his head lopped off.
