A ditch stretched across the moor, and the armies drew up with this extending for most of its length between them. Each side was marshalled in the usual order—infantry in the centre, cavalry on the flanks. The horse of the Parliamentary right wing was commanded by Sir Thomas Fairfax, who had under him his own English cavalry and three Scottish regiments. The right wing of the foot was commanded by Lord Fairfax, and consisted of the Yorkshire troops and two brigades of Scots. The centre, with its reserve, consisted of Scotch troops; the left, of the infantry of the Eastern Association. Leven was with the infantry of the centre; Manchester on his left. The horse of the left wing were under Cromwell, his Ironsides occupying the front line with three Scotch regiments in reserve.

In the Royalist army the horse on the left wing were under Goring; the infantry in the centre were under Newcastle, and Rupert himself led the horse of the right wing. At last the two great cavalry leaders of the war—Rupert and Cromwell—were to meet face to face. The war had lasted nearly two years. The best troops, under the best leaders, had reached very nearly their limit of perfectibility; they were veterans, soldiers in every sense.

Hour after hour passed while the armies stood motionless, the leaders on either side anxiously scanning the enemy, seeking to find a weak point at which to strike. Evening drew on and no move was made. The Royalist leaders made up their mind that the battle would not be fought that day. Suddenly, at seven o’clock, the whole Parliamentary army moved forward, the Puritan troopers chanting a psalm, according to their wont.

On the right, Fairfax’s troopers, as they advanced, were thrown into disorder. Goring charged them furiously, drove them back on the reserve of Scotch cavalry, and overthrew them all. The rout was hopeless, and the flying horsemen carried away the Yorkshire foot with them. Sir Thomas kept the ground, with a few of his troopers and a large number of Lord Balgony’s Scotch Lancers and the Earl of Eglinton’s Scotch Cuirassiers. The fugitives were followed in hot pursuit by Goring, but part of his horse were kept in hand by their commander, Sir Charles Lucas, who, wheeling to the right, charged the flank of the Scotch foot, who had formed the Parliamentary centre, and who had now crossed the ditch and were attacking the Royalists in front. The Scotch fought with stubborn valor, repulsing Lucas again and again, but suffering so heavily themselves that it became evident that they could not long stand the combined front and flank attack.

While disaster had thus overtaken the Parliamentary right, on the left Cromwell had completely the upper hand. His steel-clad troopers crashed into Rupert’s horsemen at full speed. The fight was equal for some time, neither stubborn Roundhead nor gallant Cavalier being able to wrest the mastery from the other. But Rupert, who always depended upon one smashing blow, and put his main force into his front line, did not, like Cromwell, understand how best to use a reserve. Cromwell’s reserve—the Scotch cavalry—came up and charged home, and the Royalist horse were overthrown with the shock. “God made them as stubble to our swords,” said Cromwell.

Cromwell’s Engagement with the Marquis of Newcastle’s Regiment of “Whitecoats” in the Battle of Marston Moor.

Sending his leading troops in pursuit, to prevent the enemy from rallying, Cromwell instantly gathered the bulk of his horse and fell on the right wing of the Royalist foot—already hard pressed by the foot of the Eastern Association. The King’s men fought with dogged courage, most conspicuous among them being Newcastle’s own Northumbrian Regiment, the famous Whitecoats, who literally died as they stood in the ranks.

Sweeping down the line the Ironsides smashed one regiment after another, until, in the fading summer evening, Cromwell had almost circled the Royalist army, and came to their left wing, where he saw the Royalist horse charging the right flank of the Scots and harrying the routed Yorkshire foot. Immediately he reformed his thoroughly trained squadrons almost on the same ground where Goring’s horse stood at the beginning of the battle, and fronting the same way. The foot of the Association formed beside them, and just before nightfall the Puritan cavalry and infantry made their final charge. Goring’s troopers were returning from their pursuit; Lucas’s men were recoiling from their last charge, in which Lucas himself had been captured. They were scattered like chaff by the shock of the steel-clad Cromwellian troopers, riding boot to boot; and the remaining Royalist foot shared the same fate. The battle was over just as night fell, stopping all pursuit. But there was little need of pursuit. As at Waterloo, the very obstinacy with which the fight had been waged made the overthrow all the more complete when at last it came. Night went down on a scene of wild confusion, with thousands of fugitives from both armies streaming off the field through the darkness; for the disaster to the right wing of the Parliamentary army had resulted not only in the rout of all the Yorkshire men and half of the Scotch, but also in the three Parliamentary commanding generals, Leven, Manchester, and Lord Fairfax, being swept off in the mass of fugitives. The fight had been won by Cromwell, not only by the valor, coolness, keen insight, and power of control over his men, which he had showed in the battle itself, but by the two years of careful preparation and drill which had tempered the splendid weapons he used so well.

This was the first great victory of the war; but it produced no decisive effect; for there was no one general to take advantage of it. York fell; but little else resulted from the triumph. Fairfax, Manchester, and Leven all separated to pursue various unimportant objects. They left Rupert time to recruit his shattered forces. They did not march south to help Essex, who was opposed to the King in person. Essex blundered badly, and when he marched into Cornwall was out-manœuvred and surrounded, and finally had to surrender all his infantry. Before this the King had already beaten the Parliamentary general, Waller, at Copredy Bridge, the defeat of the Parliamentarians being turned into disaster by the conduct of the London trained-bands, who, after two years of battle, were still mere militia, insubordinate and prone to desert. It was not with such stuff that victory over the Royalists could be obtained. Mere militia who will not submit to rigid discipline cannot be made the equals of regulars by no matter how many years of desultory fighting. In the War of the American Revolution it was the Continentals—the regulars of Washington, Wayne, and Greene—who finally won the victory, while even to the very end of the struggle the ordinary militia proved utterly unable to face the red-coats. So in the English Civil War, it was the carefully drilled and trained horse and foot of the Eastern Association, and not the disorderly London trained-bands, who overthrew the King’s men. Cromwell had developed his troops just as Grant and Lee, Sherman and Johnston long afterward developed theirs. It is only under exceptional conditions, and with wholly exceptional populations, that it is possible to forego such careful drilling and training.
