In 1643 the war widened. Charles negotiated a cease-fire with the Catholic rebels in Ireland that allowed him to bring Irish troops to England. Parliament negotiated the Solemn League and Covenant (1643) with the Scots, who brought an army to England in return for guarantees of a presbyterian church establishment. Initially Parliament benefited most. A combination of English and Scottish troops defeated royalist forces at the Battle of Marston Moor (1644) and took York. But ultimately religious differences between Scottish Presbyterians and English Independents vitiated the alliance. As the parliamentary commanders bickered, their forces were defeated at Lostwithiel (1644) and Newbury (1644). While another round of peace negotiations began, the unsuccessful Uxbridge Proposals (1645), Parliament recast its military establishment and formed the New Model Army.

There was little new about the New Model Army other than centralization. Remnants of three armies were combined to be directed by a parliamentary committee. This committee included the parliamentary generals who were displaced by the Self-Denying Ordinance (1645), an act that excluded members of Parliament from civil and military office. The New Model Army was commanded by Thomas Fairfax, Baron Fairfax, and eventually the cavalry was led by Lieut. Gen. Oliver Cromwell.

Instead, the Battle of Naseby on June 14, 1645, delivered the decisive blow to the royalists. Even though the parliamentary forces only just managed to carry the day despite their numerical superiority, their victory was decisive. It destroyed the king’s main armies and left open a path to the west, where his other substantial forces were defeated at Langport (1645). The following year, the king surrendered to the Scots, erroneously believing that they would strike a better bargain.
For four years the political divisions at Westminster had been held in check by the military emergency. But the king’s defeat released all restraints. In Parliament coherent parties began to form around the religious poles provided by Presbyterians and Independents and around the political poles of peace and war. Denzil Holles, one of the five members of Parliament Charles had tried to arrest in 1642, came to head the most powerful group. He pushed through a presbyterian church settlement, negotiated a large loan from the City of London, and used the money to ransom the king from the Scots. Holles’s peace plan was to remove the main points of difference between king and Parliament by disbanding the army and settling the disputes about the church, the militia, and the rebellion in Ireland. His party was opposed by a group led by Sir Henry Vane the Younger and Oliver Cromwell, who desired toleration for Independents and were fearful of disbanding the army before an agreement was reached with Charles I.

But war weariness in both Parliament and the country swept all before it. In January 1647 Charles was returned to English custody, and Holles moved forward with his plan to send a portion of the army to Ireland, assign a small force to English garrisons, and disband the rest. But in this he reckoned without the army. In the rank and file, concern about arrears of pay, indemnity, and liability for impressment stirred the soldiers to resist Irish service. A movement that began over material grievances soon turned political as representatives were chosen from the rank and file to present demands through their officers to Parliament. Holles attempted to brush this movement aside and push through his disbandment scheme. At this the army rose up, driving out those of its officers who supported the disbandment, seizing Charles at Holmby House on June 3 and demanding the impeachment of Holles and his main supporters. At the beginning of August 1647, the army marched into London, and Holles, with 10 of his allies, fled the capital.

The army’s intervention transformed civil war into revolution. Parliament, which in 1646 had argued that it was the fundamental authority in the country, by 1647 was but a pawn in a new game of power politics. The perceived corruption of Parliament made it, like the king, a target of reform. Initiative was now in the hands of the king and the army, and Charles I tried to entice Cromwell and Henry Ireton, the army’s leading strategist, to bargain his restoration for a tolerant church settlement. But the officers were only one part of a politicized army that was bombarded with plans for reorganizing the state. Among the most potent plans were those of the Levelers, led by John Lilburne, who desired that a new compact between ruler and ruled, the Agreement of the People (1647), be made. This was debated by the council of the army at Putney in October. The Levelers’ proposals, which had much in common with the army’s, called for the reform of Parliament through elections based upon a broad franchise and for a generally tolerant church settlement. Turmoil in the army led Fairfax and Cromwell to reassert military discipline, while the machinations of Charles led to the second Civil War (1648).

Charles had now managed to join his English supporters with discontented Scots who opposed the army’s intervention in politics. Though the fighting was brief, it was bloody. Fairfax stormed Colchester (1648) and executed the ringleaders of the English rebellion, and Cromwell and several New Model regiments defeated the invading Scots at the Battle of Preston (1648).
The second Civil War hardened attitudes in the army. The king was directly blamed for the unnecessary loss of life, and for the first time alternatives to Charles Stuart, “that man of blood,” were openly contemplated. Parliament too was appalled by the renewal of fighting. Moderate members believed that there was still a chance to bring the king to terms, despite the fact that he had rejected treaty after treaty. While the army made plans to put the king on trial, Parliament summoned its strength for one last negotiation, the abortive Treaty of Newport. Even now the king remained intransigent, especially over the issue of episcopacy. New negotiations infuriated the army, because it believed that Parliament would sell out its sacrifices and compromise its ideals. On December 6, 1648, army troops, under the direction of Col. Thomas Pride, purged the House of Commons. Forty-five members were arrested, and 186 were kept away. A rump of about 75 active members were left to do the army’s bidding. They were to establish a High Court of Justice, prepare a charge of treason against the king, and place him on trial in the name of the people of England. Pride’s Purge was a last-minute compromise made to prevent absolute military rule. With Cromwell deliberately absent in the north, Ireton was left to stave off the argument, made by the Levelers, that Parliament was hopelessly corrupt and should be dissolved. The decision to proceed by trial in the High Court of Parliament was a decision in favour of constitutional forms, however much a shadow they had become.
