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 Conde, 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
