In the opening battle of England’s War of the Roses, the Yorkists defeat King Henry VI’s Lancastrian forces at St. Albans, 20 miles northwest of London. Many Lancastrian nobles perished, including Edmund Beaufort, the duke of Somerset, and the king was forced to submit to the rule of his cousin, Richard of York.
