The king by a message represented the danger of disarming before peace were finally concluded; and he recommended to their consideration, whether he could honorably recall his forces from those towns in Flanders which were put under his protection, and which had at present no other means of defence. The commons agreed to prolong the term with regard to these forces. Every thing, indeed, in Europe bore the appearance of war. France had positively declared, that she would not evacuate the six towns before the requisite cession was made to Sweden and her honor seemed now engaged to support that declaration. Spain and the empire, disgusted with the terms of peace imposed by Holland, saw with pleasure the prospect of a powerful support from the new resolutions of Charles. Holland itself, encouraged by the prince of Orange and his party, was not displeased to find that the war would be renewed on more equal terms. The allied army under that prince was approaching towards Mons, then blockaded by France. A considerable body of English, under the duke of Monmouth, was ready to join him.
Charles usually passed a great part of his time in the women's apartments, particularly those of the duchess of Portsmouth; where, among other gay company, he often met with Barillon, the French ambassador, a man of polite conversation, who was admitted into all the amusements of that inglorious but agreeable monarch. It was the charms of this sauntering, easy life, which, during his later years, attached Charles to his mistresses. By the insinuations of Barillon and the duchess of Portsmouth, an order was, in an unguarded hour, procured, which instantly changed the face of affairs in Europe. One Du Cros, a French fugitive monk, was sent to Temple, directing him to apply to the Swedish ambassador, and persuade him not to insist on the conditions required by France, but to sacrifice to general peace those interests of Sweden. Du Cros, who had secretly received instructions from Barillon, published every where in Holland the commission with which he was intrusted; and all men took the alarm. It was concluded that Charles's sudden alacrity for war was as suddenly extinguished, and that no steady measures could ever be taken with England. The king afterwards, when he saw Temple, treated this important matter in raillery; and said, laughing, that the rogue Du Cros had outwitted them all.
