Fairfax encountered little difficulty on the part of the officers and soldiers called upon to serve under his orders. Essex loyally advised his friends, Cromwell hastened to proceed to preach submission to the battalions of the Ironsides. As he had fully resolved, he was not long separated from them. Towards the end of April, Fairfax was about to open the campaign, when Cromwell arrived at Windsor to kiss, he said, the hand of the general and to bring his resignation to him. "I have just," Fairfax said, "received from the Committee of the Two Kingdoms orders enjoining you to proceed immediately, with a few squadrons, to the road from Oxford to Worcester to intercept communications between Prince Rupert and the king." Cromwell immediately set out. Three brilliant skirmishes and the capture of the town of Blechingdon signalized his march. Parliament voted that Cromwell should retain his command for forty days longer. Three other members of the House of Commons, distinguished officers, received the same instructions, doubtless in order that Cromwell should not appear to be alone excepted from the operation of the law. {134} Meanwhile the king, having issued forth from Oxford, had joined Prince Rupert, and was advancing rapidly towards the north. The siege of Chester was raised at his approach, and he directed his course towards the associated counties of the east. A few days later, he took possession of Leicester. Fairfax, who was besieging Oxford by the order of the Committee of the two kingdoms, had made no movement to hinder the course of his successes. The Presbyterians were already triumphant. "There then is the fruit of this reorganization which was so much vaunted," they said; "the king in one day takes our best towns, and your general remains motionless before Oxford, waiting, doubtless, for the women of the court to take alarm and open the gates to him." They did not speak of the inaction of the Scotch, who had fallen back upon their frontiers instead of marching to meet the king. Fairfax received orders to raise the siege of Oxford, to seek the king and give battle to him at all costs. In his turn, he wrote to the Houses to demand the prolongation of the service of Cromwell. Sixteen colonels signed the letter. On the 12th of June, in the environs of Northampton, some Parliamentary horsemen, sent to reconnoitre, suddenly came up with a detachment of the army of the king.
