24. =The Campaign of Marston Moor. 1644.=--The spring campaign opened successfully for Parliament. In March, indeed, Rupert relieved Newark, which was hardly pressed by a Parliamentary force; but in March Waller defeated Hopton at Cheriton near Alresford, whilst in the North, Sir Thomas Fairfax, together with his father, Lord Fairfax, seized upon Selby, and joined the Scots in besieging York, into which Newcastle had been driven. In May, Manchester stormed Lincoln, and he too joined the forces before York. At the king's headquarters there was deep alarm. Essex and Waller were approaching to attack Oxford, but Charles slipping out of the city before it was surrounded despatched Rupert to the relief of York. At Rupert's approach the besiegers retreated. On July 2 Rupert and Newcastle fought a desperate battle on Marston Moor, though they were decidedly outnumbered by their opponents. The whole of the right wing of the Parliamentarians, and part of the centre, fled before the Royalist attack; but on their left, Cromwell restored the fight, and drove Rupert in flight before him. Cromwell did not, however, as Rupert had done at Edgehill, waste his energies in the pursuit of the fugitives. Promptly drawing up, he faced round, and hurled his squadrons upon the hitherto victorious Royalists in the other parts of the field. The result was decisive. "It had all the evidence," wrote Cromwell, "of an absolute victory, obtained by the Lord's blessing upon the godly party principally. We never charged but we routed the enemy. God made them as stubble to our swords." All the north of England, except a few fortresses, fell into the hands of Parliament and the Scots.
