York decided that he could protect himself was only by defeating the king in battle. He raised an army of many people who were unhappy with Henry and Margaret, which led to the First Battle of St Albans in 1455. That was the first to be fought between the Yorkists, who supported York, and the Lancastrians (who supported Henry). York won with the help of the Richard Neville, Earl of Warwick. Henry was found hiding in a leather shop, taken prisoner and was again overcome with mental illness. Somerset and some of the king's other key supporters were killed in the battle. York was again made Lord Protector.
