The Duke of Somerset, of the Lancastrian party, is a young and haughty lord, who despises Richard Plantagenet for being the son of a traitor, and is incensed when the latter is restored to his father’s lands and named Duke of York.
His quarrel with Richard on this matter leads to a breach that will become the War of the Roses; he does not hold to his word to give in if more people side against him than with him. Named to an equal command with the new Duke of York in France, he refuses to collaborate with him, thereby leaving Talbot without help and causing his death. He refuses to accept any blame for Talbot’s demise. He cares only for his own good, nothing for the kingdom. He returns in Henry VI, Part Two.
