York's first protectorate did not last long. Early in 1455 the king rallied sufficiently to return to power, at least nominally, with Somerset again wielding real power. Warwick returned to his estates, as did York and Salisbury, and the three started raising troops. Marching towards London, they encountered the king at St Albans, where the two forces clashed. The battle was brief and not particularly bloody, but it was the first instance of armed hostilities between the forces of the Houses of York and Lancaster in the conflict known as the Wars of the Roses. It was also significant because it resulted in the capture of the king, and the death of Somerset.
