Two years later he was appointed Master of the Great Wardrobe and Custos Rotulorum of Warwickshire and Earl of Denbigh on 14 September 1622., He attended Prince Charles on the Spanish adventure, served as admiral in the unsuccessful Cadiz Expedition in 1625, and commanded the disastrous attempt upon Rochelle in 1628, becoming the same year a member of the Council of war, and in 1633 a Member of the Council of Wales and the Marches.
