The Battle of Baugé, fought between the English and a Franco-Scots army on 22 March 1421 at Baugé, France, east of Angers, was a major defeat for the English in the Hundred Years' War. The English army was led by the king's brother Thomas, Duke of Clarence, while the Franco-Scots were led by both John Stewart, Earl of Buchan, and Gilbert Motier de La Fayette, the Marshal of France. English strength was 4,000 men, although only 1,500 deployed, against 5,000 French and Scots.

Thomas of Lancaster, Duke of Clarence was a medieval English prince and soldier, the second son of Henry IV of England, brother of Henry V, and heir to the throne in the event of his brother's death. He acted as counselor and aide to both.
