As always, Cromwell's tenderness towards the Republicans or Old Commonwealth's men appeared now in his dealings with the new commotion on that side. Colonel Packer and Captain Gladman, two disaffected officers in his own regiment of horse, appear to have been merely dismissed from their commands; and one hears besides of but a few arrests, with no farther consequences than examination before the Council and temporary imprisonment. Harrison was again arrested, the Fifth-Monarchy men having, of course, lent themselves to the agitation, and Harrison having this time, Whitlocke says, been certainly "deep in it." Among the others arrested were Mr. John Carew, the Regicide and Councillor under the Commonwealth, John Portman, who had been secretary to Blake in the Fleet, a Hugh Courtney, and John Rogers, a preacher. There seems to have been no thought of any proceedings against Hasilrig, Scott, Sir Anthony Ashley Cooper, and the other Anti-Cromwellian leaders in the late Parliament. This, however, is less remarkable than that, with information in Cromwell's possession that some of the members of the Parliament, nominally Commonwealth's men, had actually commissions from Charles II. and were enlisting persons under such commissions for any possible insurrection whatever, he had contented himself with announcing the fact in his Dissolution Speech and so merely signifying to the culprits that their lives were in his hands.1

The Royalist project and its ramifications were really very formidable. A Spanish Army of about 8000 men, with Charles II. and his refugees among them, was gathered about Bruges, Brussels, and Ostend, with vessels of transport provided; and the burst of a great Royalist Insurrection at home, in Sussex, London, and elsewhere, was to coincide with the invasion from abroad. The Duke of Ormond himself had come to London in disguise, to observe matters and make preparations. He was in London for three weeks, living in the house of a Roman Catholic surgeon in Drury Lane, till Cromwell, who knew the fact, generously sent Lord Broghill to him with a hint to be gone. This was early in March, some days after a proclamation "commanding all Papists and other persons who have been of the late King's party or his son's to depart out of the cities of London and Westminster," and another proclamation forbidding such persons living in the country to stir more than five miles from their fixed places of abode. On the 12th of that month the Lord Mayor, Aldermen, and Common Council of the City of London met his Highness and the Army-officers by appointment at Whitehall, where his Highness explained to them at length the nature of the crisis, informed them particularly of the strength of the Flanders army of invasion, Ormond's visit, &c., and solemnly committed to them the safety of the City. The response of the City authorities was extremely loyal.1

The Proclamation ordering Papists and other Royalists out of London and Westminster, and that ordering such persons in the country to keep near home, are both dated Feb. 25, 1657-8. There are copies at the end of one of the volumes of the Council's minutes.

On the principle that the country could not afford for ever this periodical trouble of a Royalist Conspiracy, and that some examples of severity might make the present upheaving the last of the kind, Cromwell had resolved on a few such examples. His information, through Thurloe and otherwise, was unerring. He knew, and had known for some time, who were the members of the so-called "Sealed Knot," i.e. that secret association of select Royalists resident in England who were in closest correspondence with Hyde and the other Councillors of Charles abroad, and were chiefly trusted by them for the management of the cause at home, Indeed, Sir Richard Willis, one of the chiefs of the "Sealed Knot," had for some time been in understanding with Cromwell, pledged to him by a peculiar compact, and revealing to him all that passed among the Royalists. Hence, before the end of April, some of the members of the "Sealed Knot," and a number of leading Royalists besides, had been lodged in the Tower. Among them were Colonel John Russell (brother of the Earl of Bedford), Colonel John White, Sir William Compton, Sir William Clayton, Sir Henry Slingsby (a prisoner in Hull since the Royalist rising of 1654-5, but negotiating there desperately of late to secure the officers and the town itself for Charles), Sir Humphrey Bennett, Mr. John Mordaunt (brother of the Earl of Peterborough), Dr. John Hewit (a London Episcopal clergyman), Mr. Thomas Woodcock, and a Henry Mallory. It was part of the understanding with Willis that several of the prisoners, Willis's particular friends, should be ultimately released. For trial were selected Slingsby, Clayton, Bennett, Mordaunt, Woodcock, Mallory, and Dr. Hewit. The trials were in Westminster Hall, in May and June, before a great High Court of Justice, consisting of all the judges, some of the great state officers, and a hundred and thirty commissioners besides, all in conformity with an Act of the late Parliament prescribing the mode of trial for such prime offences. Five of the seven were either acquitted or spared: only Slingsby and Dr. Hewit were brought to the scaffold. They were beheaded on Tower Hill, June 8. Much influence was exerted in behalf of Hewit; but, besides that he had been deeply implicated, he had been contumacious in the Court, challenging its competency, and refusing to plead. Prynne had stood by him, and prepared his demurrer.—From the evidence collected in Dr. Hewit's case it appeared that he, if not Ormond, had been calculating on the co-operation of Fairfax, Lambent, Sir William Waller, and a great many other persons of name, up and down the country, not included among those whom Cromwell had seen fit to arrest. As Thurloe distinctly says, "It's certain Sir William Waller was fully engaged," the omission, of that veteran commander from the number must have been an act of grace. About Lambert the speculation seems to have been absurd; and, though Cromwell must have known that Fairfax was now inclining generally towards a Restoration, he cannot have believed anything stronger at present in his case. There was no public reference to such high personages; nor, with the exception of some friendly expostulation by the Protector with a young Mr. John Stapley of Sussex (son of Stapley the Regicide and Councillor of the Commonwealth), who had been lured into the business, was any account taken of the other miscellaneous persons in Hewit's list of reputable sympathisers. It was enough for Cromwell to know who had swerved so far, and to have made examples of Hewit himself and Slingsby.—These two would have been the only victims but for a wild sub-conspiracy in the City of London while the trials of Hewit and Slingsby were in progress. A few desperate cavaliers about town, the chief of whom were a Sir William Leighton, a Colonel Deane, and a Colonel Manley, holding commissions from Charles, had met several times at the Mermaid Tavern and elsewhere, and had arranged for a midnight tumult on Saturday the 15th of May. They were to attack the guard at St. Paul's, seize the Lord Mayor, raise a conflagration near the Tower, &c. The hour had come, and the conspirators were in the Mermaid Tavern for their final arrangements, when lo! the trainbands on the alert all round them and Barkstead riding through the streets with a train of five small cannon. A good many were arrested, thirty of them London prentices. Six of the principals were condemned July 2, of whom one was hanged, two were hanged, drawn, and quartered, and three were reprieved. For the prentices there was all clemency.1

Though the prosecutions of the Royalist plotters were not concluded till the beginning of July, all real danger from the plot itself had been over in March or April, when Ormond was back in Bruges with the report that his mission had been abortive and that Cromwell was too strong. We must go back, therefore, for the other threads of our narrative.

The death of Mr. Robert Rich, Cromwell's son-in-law since the preceding November, had occurred Feb. 16, 1657-8, only twelve days after the dissolution of the Parliament. Cromwell, saddened by the event himself, had found time even then to write letters of condolence and comfort to the young man's grandfather, the Earl of Warwick. The Earl's reply, dated March 11, is extant. "My pen and my heart," it begins, "were ever your Lordship's servants; now they are become your debtors. This paper cannot enough confess my obligation, and much less discharge it, for your seasonable and sympathising letters, which, besides the value they deserve from so worthy a hand, express such faithful affections, and administer such Christian advice, as renders them beyond measure welcome and dear to me." Then, after pious expression at once of his grief and of his resignation, he concludes with words that have a historical value. "My Lord," he says, "all this is but a broken echo of your pious counsel, which gives such ease to my oppressed mind that I can scarce forbid my pen being tedious. Only it remembers your Lordship's many weighty and noble employments, which, together with your prudent, heroic, and honourable managery of them, I do here congratulate as well as my grief will give me leave. Others' goodness is their own; yours is a whole country's, yea three kingdoms'—for which you justly possess interest and renown with wise and good men: virtue is a thousand escutcheons. Go on, my Lord; go on happily, to love Religion, to exemplify it. May your Lordship long continue an instrument of use, a pattern of virtue, and a precedent of glory!" On the 19th of April 1658, or not six weeks after the letter was written, the old Earl himself died. By that time the louring appearances had rolled away, and Cromwell's "prudent, heroic, and honourable managery" had again been widely confessed.1

Through all the turmoil of the proceedings against the plotters Cromwell had not abated his interest in his bold enterprise in Flanders, or in his alliance with the French generally. That alliance having been renewed for another year (March 28, 1658), reinforcements were sent to the English auxiliary army to fit it for farther work in the Netherlands. Sir John Reynolds, the first commander of that army, having been unfortunately drowned in returning to England on a short leave of absence (Dec. 5, 1657), the Governorship of Mardike had come into the hands of Major-General Morgan, while the command in the field had been assigned to Lockhart, hitherto the Protector's Ambassador only, though soldiering had been formerly his more familiar business. In conjunction with Turenne, Lockhart had been pushing on the war, and at length (May 1658) the two armies, and Montagu's fleet, were engaged in the exact service which Cromwell most desired, and Lockhart had been always urging. This was the siege of Dunkirk, with a view to the possession of that town, as well as Mardike, by the English. To be near the scene of such important operations, Louis XIV. and Cardinal Mazarin had taken up their quarters at Calais; and, not to miss the opportunity of such near approach of the French monarch to the shores of England, Cromwell despatched his son-in-law Viscount Falconbridge on a splendid embassy of compliment and congratulation. He landed at Calais on the 29th of May, was received by both King and Cardinal with such honours as they had never accorded to an ambassador before, and returned on the 3rd of June to make his report. The very next day there was a tremendous battle close to Dunkirk between the French-English forces under Turenne and Lockhart and a Spanish army which had come for the relief of the besieged town under Don John of Austria and the Prince of Condé, with the Dukes of York and Gloucester in their retinue. Mainly by the bravery of Lockhart's "immortal six thousand," the victory of the French and English was complete; and, though the Marquis of Leyda, the Spanish Governor of Dunkirk, maintained the defence valiantly, the town had to surrender on the 14th of June, two days after the Marquis had been mortally wounded in a sally. Next day, according to the Treaty with Cromwell, the town was at once delivered to Lockhart, Louis XIV. himself, who was on the spot, handing him the keys. Already, while that event was unknown, and merely to reciprocate the compliment of Falconbridge's embassy to Calais, there had been sent across the Channel, in the name of Louis XIV., the Duke de Crequi, first Gentleman of his Bedchamber, and M. Mancini, the nephew of Cardinal Mazarin, "accompanied by divers of the nobility of France and many gentlemen of quality." Met at Dover by Fleetwood and an escort, they arrived in London June 16, and remained there till the 21st, having audiences with his Highness, delivering to him letters from Louis and the Cardinal, and entertained by him with all possible magnificence. While they were there, a special envoy joined them, announcing the capture of Dunkirk; and so the joy was complete. There was nothing the French King would not do to show his regard for the great Protector; and, but for his Majesty's illness at that moment from small-pox, the Cardinal himself would have come over instead of sending his nephew. And why should there not be a renewal of the Treaty after the expiry of the present term, to secure another year or two of that co-operation of the English Army and Fleet with Turenne which had led already to such excellent results? What if Ostend, as well as Dunkirk and Mardike, were to be made over to the Protector? These were suggestions for the future, and meanwhile new successes were added to the capture of Dunkirk. Town after town in Flanders, including Gravelines at last, yielded to Turenne, or other generals, and received French garrisons, and through the summer autumn the Spaniards were so beset in Flanders that an expedition thence for the invasion of England in the interest of Charles Stuart, or in any other interest, was no longer even a possibility.1
