Morgan opened the campaign before the arrival of Lockhart by the capture of two small redoubts that lay on the road to Dunkirk; but it was not till the 4th of May that Turenne broke up his quarters at Amiens, and after a very difficult march to Dunkirk, on the 27th invested the town. A brilliant repulse of a Spanish sortie by the English put him in good humour with his allies, and he was fain to confess that they had done right well.[191] He was to appreciate them still higher within a week; for on the 2nd of June the Spanish army, fifteen thousand strong, under Don John of Austria, Condé, the Marquis Caracena, and James, Duke of York, drew down to within a mile of his headquarters, with the evident design of forcing the besiegers' lines. We must pause for a moment over the composition of the motley Spanish host, for there is a part of it under James, Duke of York, with which we are nearly concerned. Five regiments in all, amounting to some two thousand men, were entrusted to the Duke's command. Three of these, James's own, Lord Ormonde's, and Lord Bristol's, were Irish, the relics of the loyal party that had been scattered by Cromwell; one, Middleton's, was Scotch, and represented fragments of the force that had been broken up by Monk; and one, which readers must not omit to mark, was English, made up of refugees mostly of gentle birth. It comprehended the last shreds of old English royalism, and was called the King's Regiment of Guards. Nor must we omit to throw a passing glance at the army of Turenne. First and foremost there were the six regiments sent out by Cromwell. Then there was a regiment with which we parted last after the battle of Verneuil, the Scottish body-guard of the kings of France. Next, there was a regiment which we saw pass from the Swedish to the French service in 1635, Regiment Douglas, some time the Scots Brigade of King Gustavus Adolphus. It had passed through many campaigns and absorbed other corps of British within the past twenty years, and could now add the names of Rocroi, Lens and Fribourg to its records; but here it was, newly recruited from Scotland by the Protector's permission, marching side by side with the red-coats, though quite unconscious how soon it was destined to take its place among them, to fight the battle of Dunkirk Dunes. Lastly, an Irish regiment, known by the name of Dillon, and made up of men who had fled from the wrath of Cromwell, completed the strange representation of the united Commonwealth.[192]
