‘I did indeed take arms for a time in the employ of the United Provinces, by which means I came face to face once more with mine old foes, the Roundheads. Oliver had lent Reynolds’s brigade to the French, and right glad was Louis to have the service of such seasoned troops. ‘Fore God, I stood on the counterscarp at Dunkirk, and I found myself, when I should have been helping the defence, actually cheering on the attack.
