To Cromwell the general aspect of things had become well nigh intolerable. But it was in vain that he endeavoured to move the heavy spirit of his superior, the Earl of Manchester, and hence they came more and more to disputes. Cromwell was insubordinate because it was impossible that fire could be subordinate to earth. In vain he pointed out what ought to be done, and he grew impatient and irritated at what was not done. That irritation and impatience became the greater as he turned his eyes on what Essex, Waller, and the rest of the Parliamentary generals were doing. It seemed to him that they were asleep, paralysed, when a few bold strokes would bring the war to a close. Charles having broken up Essex's army in Cornwall, and put Essex himself to flight, made a hasty march back again to Oxford to avoid being himself in turn cooped up in the narrow West. Already the Parliament was mustering its forces for that purpose. Essex and Waller were again set at the head of troops, and the victorious forces of Marston Moor, under Manchester and Cromwell, were summoned to join them. They endeavoured to stop the king in his attempt to reach Oxford, and encountered him again near the old ground of battle at Newbury. Charles was attacked in two places at once--Shaw on the eastern, and at Speen on the western side of the town. The Earl of Essex was ill, or, as many believed, pretended to be so; at all events, the command fell to Manchester. On the 26th of October, the first brush took place, and the next morning being Sunday, the attack was renewed more vigorously. The soldiers of Manchester, or rather of Cromwell, went into the fight singing psalms, as was their wont. The battle was fiercely contested, and it was not till ten o'clock at night that Charles retreated towards Wallingford. It was full moonlight, and Cromwell prepared to pursue him, but was withheld by Manchester. Again and again did Cromwell insist on the necessity of following and completing the rout of the royal army. "The next morning," says Ludlow, "we drew together and followed the enemy with our horse, which was the greatest body that I saw together during the war, amounting at least to seven thousand horse and dragoons; but they had got so much ground, that we could never recover sight of them, and did not expect to see any more in a body that year; neither had we, as I suppose, if encouragement had not been given privately by some of our party."
