A few days afterwards nearly the whole of his old regiment had enlisted with Fairfax, while he and Warren were sent prisoners to Hull. But for such a man Hull was not safe enough. It had but recently been relieved, and was not out of danger so long as Lord Newcastle was at York. Fairfax and the other officers who had fought by Monk's side in the Low Countries knew well the value of his services, and impressed upon the Parliament that he was "a man worth the making," and not without effect. He was ordered up to London with Warren, and on July 8th brought to the bar of the House. There the two unfortunate officers were charged with high treason and committed to the Tower. No sooner were they there than Lord Lisle set about justifying his boasts to the Council. He was still doing his best to get appointed Lord Lieutenant of Ireland, and there could be no better testimonial to his fitness than that he could command the services of the officers in the Tower. Of Monk there was every hope, for he alone had refused to bind himself not to serve the Parliament, nor were the most enticing offers wanting to tempt him. Already the New Model Army was in contemplation. Men of all parties saw that nothing decisive would ever be done except by adopting the methods which Monk had urged on the King. A compact mobile field-force, complete and organised in every detail on the Low Country system, must replace the unmanageable mobilised militia with which the war had hitherto been aimlessly dragged on. Cromwell had now definitely come to the front and thrown himself into the task. Except possibly Sir Jacob Astley, who was at Oxford with Charles, there was no one in the kingdom more fitted for the all-important work than Monk. Cromwell, who knew how to choose a man, must have been perfectly aware of his qualifications, even if he had not been as intimate as he was with Lord Lisle. Nor was it from Cromwell alone that the prisoner was tempted. Though all were agreed the weapon must be forged, they were by no means at one as to the hands in which it was to be placed. Independents and Presbyterians were manoeuvring for the control. In spite of standing orders members were so constantly visiting the prisoners that the House had strictly to forbid the practice without special leave. The same day a leading Presbyterian was granted permission, and towards the end of October Monk's case was specially referred to the committee of examinations. But they all mistook their man. He still held the King's commission. The war for which he had engaged was still raging, and the most brilliant offers that could be made him he only regarded as insults. Pressure was even brought to bear, it is said, by a more rigorous confinement, but it was useless, and he indignantly refused his liberty except by a regular cartel.
