Cromwell, as was his usual habit, ascribed this success to Divine aid. "I can say this of Naseby," he wrote, "that when I saw the enemy draw up and march in gallant order towards us, and we a company of poor ignorant men to seek to order our battle, the General having commanded me to order all the horse, I could not--riding alone about my business--but smile out to God praises in assurance of victory, because God would, by things that are not, bring to naught things that are, of which I had great assurance--and God did it." No doubt, as has been said, Cromwell omitted to mention that the Parliamentary army had numbers on its side--not much less than 14,000, opposed to 7,500. But it was not the numerical superiority of the Parliamentarians which won the day. It did not enable Ireton to withstand Rupert, and the infantry in the centre was already giving way when Cromwell returned to assist it. It was the discipline rather than the numbers of Cromwell's horse aided by the superb generalship of their commander that gained the day. Cromwell, when he wrote of his soldiers as 'poor ignorant men,' was doubtless glancing back in thought at his own early criticism of the fugitives at Edgehill. The yeomen and peasants whom he had gathered round him owed much to discipline and leadership; but they owed much also to the belief embedded in their hearts that they were fighting in the cause of God. After the victory at Naseby the issue of the struggle was practically decided. There was another fight at Langport, where Fairfax defeated a force with which Goring attempted to guard the western counties; but after this the war resolved itself into a succession of sieges which could end but in one way as Charles had no longer a field army to bring to the relief of Royalist garrisons. For some months Cromwell, sometimes in combination with Fairfax, sometimes in temporary command of a separate force, was untiring in the energy which he threw into his work. Charles was full of combinations which never resulted in practical advantage to his cause. At one time his hopes were set upon Montrose, who, after his brilliant victories, expected to bring an army of Highlanders to aid of the royal cause. At another time he looked with equal hopefulness to Glamorgan, who was to conduct an Irish army to England. Montrose's scheme was wrecked at Philiphaugh, and Glamorgan's concessions to the Irish Catholics were divulged and had to be disavowed. On March 31, 1646 Sir Jacob Astley bringing 3,000 men, the last Royalist force in existence, to the relief of Charles at Oxford, was forced to surrender at Stow-on-the-Wold. "You have done your work," said the veteran to his captors, "and may go play, unless you will fall out among yourselves." Though Oxford and Newark were still untaken, the end of the war was now a mere question of days.
