The Royalists soon became concerned about the Parliamentarian activities and in the fall of 1643, King Charles took steps to regain control of Cheshire for the Royalists. First, in October King Charles rearranged military commands, appointed John Byron Baron Byron, and gave him command of all Royalist forces in Cheshire and Lancashire. Then in November, King Charles supplemented the Royalist forces in Cheshire by bringing home part of the English and Welsh armies that had been sent in 1641-1642 to Ireland to deal with the Irish Catholic Rebellion. Given a new command and responsibility, Lord Byron planned to capture the Parliamentarian headquarters at Nantwich, clear the enemy from Cheshire, and then address Lancashire.
