Lord Herbert left the castle to join the campaign against Parliament, returning at intervals to acquire more funds for the war. Charles I himself visited the castle twice, first in June 1645 after the battle of Naseby and again in 1646, when he enjoyed playing bowls on the castle's green. The Royalist cause was now close to military collapse, and the Marquess started to send some valuables, including the oak panelling from the parlour, some plaster ceiling and many pictures, to his brother at nearby Troy House for safe-keeping. Lord Herbert was captured in Ireland, and an attack on Raglan itself appeared imminent.
