There is reason to believe that Cromwell's instructions only gave authority for the removal of the King from Holmby conditionally on its appearing that he could in no other way be preserved from abduction by the Presbyterians. When on June 1 Joyce arrived at Oxford, he found that the garrison had resolved to refuse the delivery of the guns, and on the following day he marched on to Holmby with some 500 horsemen at his back. On his arrival Graves took to flight, and the garrison of the place at once fraternised with the new-comers. In the early morning of the 3rd Joyce, followed by his men, was let in by a back door asserting that he had come to hinder a plot 'to convey the King to London without directions of the Parliament'. "His mission," he further stated, was "to prevent a second war discovered by the design of some men privately to take away the King, to the end he might side with that intended army to be raised; which, if effected, would be the utter undoing of the kingdom." To this profession his actions were suitable. During the whole of the day he remained quiet, never hinting for an instant that he had any intention of doing more than preserve the King's person against violence. In the course of the day, however, he took alarm at some rumours of an impending attack, and made up his mind, probably nothing loth, that the danger could only be met by removing the King to safer quarters. About half-past ten at night he roused Charles from his slumbers, invited him to follow him on the following morning, and on giving assurances that no harm would follow received the promise he required. On the morning of the 4th, as Charles stepped from the door of the house, he was confronted by Joyce and his 500 troopers. The King at once asked whether Joyce had any commission for what he was doing. "Here," replied Joyce, turning in the saddle as he spoke, and pointing to the soldiers he headed, "is my commission. It is behind me." "It is a fair commission," replied Charles, "and as well written as I have seen a commission in my life: a company of handsome, proper gentlemen, as I have seen a great while." Having selected Newmarket as his place of residence, Charles not unwillingly, as it seemed, set out in this strange companionship. On that very morning, or on the previous evening, Cromwell, feeling himself no longer safe at Westminster, slipped away and rode off to join the army at Newmarket. Both Fairfax and Cromwell declared for the King's return to Holmby, no doubt considering Joyce's removal of the King to be unnecessary, and, under the circumstances, unauthorised. It was only on Charles's positive refusal to return that he was allowed to continue his journey.
