garrisons, chiefly Oxford and Newark. Rossiter did not participate in the New Model's 1645 Western Campaign, but remained in the region. He played a prominent part in the administration of the Eastern Association, and on 6 October 1645, he captured letters outlining Royalist attempts to win support from the Irish Confederacy. Claims that Charles wanted to employ Irish Catholics in England had been a recurring element in Parliamentarian propaganda, and they were published as proof he could not be trusted. Another of his functions was negotiating with Royalists who wanted to surrender; when Prince Rupert and his brother Maurice were dismissed by Charles in October, they applied to Rossiter for passes to leave England, a request quickly granted by Parliament. In March 1646, Rossiter was nominated MP for Great Grimsby in place of Gervase Holles, excluded Royalist cousin of Denzil Holles. Now close to defeat, Charles left Oxford in disguise on 27 April and joined the Scots Covenanter army outside Newark, which surrendered the next day. Despite furious objections from Parliament, the Scots withdrew north to Newcastle, taking the king with them. Second English Civil War Parliament went to war to achieve a political settlement with the king, not remove him, but arguments over the terms divided mostly Presbyterian moderates in Parliament from radicals within the New Model. At the end of January 1647 the Committee of Both Kingdoms that had governed England and Scotland since February 1644 was dissolved and replaced by the Derby House Committee, led by Holles and dominated by moderate MPs, including Rossiter. They paid the Scots £400,000 to return to Scotland and hand over Charles, who was escorted to Holdenby House, near Holmby in Northamptonshire, where Rossiter's regiment formed part of his guard. Divisions between Parliament and the Army Council were exacerbated by financial issues and by March 1647, the New Model was owed more than £2.5 million in unpaid wages. Parliament ordered it to Ireland, stating only those who agreed would be paid; when their representatives demanded full payment for all in advance, it was disbanded, but the Army Council refused to comply. In early June, troops from the New Model removed Charles from Holdenbury House; viewed by the Army Council as unreliable, Rossiter was dismissed in August. When the Second English Civil War broke out in April 1648, the New Model faced multiple risings throughout England and South Wales, as well as a
