the killings had the king's sanction, which, for many, foreshadowed their own fate if the king's Irish troops landed in Britain. Thus the English Parliament refused to pay for a royal army to put down the rebellion in Ireland; instead Parliament decided to raise its own armed forces. The king did likewise, rallying those Royalists (some of them members of Parliament) who believed their fortunes were best served by loyalty to the king. The English Civil War ignited in 1642. Scottish Covenanters (as Presbyterians there called themselves) joined forces with the English Parliament in late 1643 and played a major role in the ultimate Parliamentary victory. Over the course of more than two years, the king's forces were ground down by the efficiency of those of Parliament, including the New Model Army, backed as they were by the financial muscle of the City of London. On 5 May 1646, at Southwell, Charles I surrendered to the Scottish army besieging Newark-on-Trent. What remained of the English and Welsh Royalist armies and garrisons surrendered piecemeal over the next few months. Meanwhile, the rebellious Irish Catholics formed their own government—Confederate Ireland—intending to help the Royalists in return for religious toleration and political autonomy. Troops from England and Scotland fought in Ireland, and Irish Confederate troops mounted an expedition to Scotland in 1644, sparking the Scottish Civil War. There, the Royalists gained a series of victories in 1644–1645, but were crushed after the main Covenanter armies returned to Scotland upon the end of the first English Civil War. The Scots handed Charles over to the English and returned to Scotland, the English Parliament having paid them a large sum for their expenses in the English campaign. After his surrender, Charles was approached by the Scots, the Presbyterians in the English Parliament, and the Grandees of the New Model Army, all attempting to reach an accommodation with him and among themselves which would achieve peace while preserving the crown. But now, a breach between the New Model Army and Parliament widened day by day, until the Puritans in Parliament, with allies among the Scots and the remaining Royalists, saw themselves strong enough to challenge the Army, which began the Second English Civil War. The New Model Army vanquished the English Royalist and Parliamentarians, as well as their Scottish Engager allies. On account of his secret machinations with the Scottish Engagers, Charles was charged with treason
