Even without direct proof of Cromwell's guilty complicity in that attempt, it is brought home to him by a variety of antecedent circumstances. He knew precisely how to spread the only lure that could ensnare the King; for the counsels of the 'Sealed Knot' were no secret to Cromwell. He was aware that the King had, in consequence, written, 4th Jan. 1655, to Mr. Roles, 'his loving friend,' and probably also the Protector's friend, in a tone of utter despair.[33] And who could set against the King a stream of systematic false encouragement, sufficient to dispel his just despair, except Cromwell, who had all the secret agents at home and abroad at his command? or who would undertake so difficult a task as the creation of such an elaborate scheme of deception, but one who was anxious that the outbreak should take place? And we know that such was his wish. In every way this is apparent. Even though no actual assistance be given, still complete foreknowledge of a coming mischief, unfollowed by corresponding precautions, implies a sanction. And this form of sanction Cromwell gave to the Insurrection. In a tone of triumphant cunning he assured his Parliament, during the ensuing year, that he had possessed 'full intelligence of' the conspiracy; though, with characteristic craft, he concealed the most effectual informant 'of these things,' the clerk who wrote out the despatches in the King's closet; and poor Manning, 'as he was dead,' was credited with the discovery; although his term of espial was not commenced soon enough to supply that 'full intelligence,' of which his employer boasted.[34] Cromwell could even have informed his corps of informers, of the course that the coming movement would pursue. Two months before they began to reflect back to him an account of his own design, Cromwell's detection office in Whitehall contained a report from a supposed Leveller, who had passed from Essex to Cornwall, and then from Cornwall to Scotland, that a rumour was afloat, that the republicans in the army who were 'resolved to stand by their first principles, in opposition to the Government,' had banded together, under noted leaders, and had chosen the very places afterwards selected by the Royalists, namely, Salisbury Plain and Marston Moor for the rendezvous where they might show their strength. Other informers reported to Cromwell that the Royalists in London, and in Northumberland, hoped, that if they appeared in arms, they would be able to 'make use of a good part of the army;' and similar evidence warned the Government that a man claiming to be a Royalist had been at work, during February, journeying to and fro between Gloucestershire and Wiltshire, tempting Royalists to join with him in an insurrection, because 'the design was first put on foot by the Levellers, who were to be aiding and assisting the Cavaliers.'[35]
