St. Alban's (Wars of the Roses).
Two engagements were fought here in the course of the war. On May 22, 1455, 2,000 Lancastrians, under Henry VI, posted in the town, were attacked by 3,000 Yorkists, under the Duke of York. The Duke pierced the Lancastrian centre, and drove them out of St. Alban's with heavy loss, among those who were killed being the Earls of Somerset and Northumberland.
The second battle took place February 17, 1461, when the army of Margaret of Anjou, led by Somerset, Exeter, and others, attacked the Yorkists, under Warwick, Warwick withdrew his main body, leaving his left unsupported to withstand the Lancastrian attacks, and these troops, after a feeble resistance, broke and fled. Henry VI, who was a prisoner in Warwick's camp, escaped and rejoined the Queen, and a rapid advance on London would probably have led to his reinstatement. Warwick, however, took such prompt measures as to render the Lancastrian victory practically fruitless.
