Louis XIV.’s first campaign had been nothing but playing at war, almost entirely without danger or bloodshed; it had, nevertheless, been sufficient to alarm Europe. Scarcely had peace been concluded at Breda, when another negotiation was secretly entered upon between England, Holland, and Sweden.
It was in vain that King Charles II. leaned personally towards an alliance with France; his people had their eyes “opened to the dangers” —incurred by Europe from the arms of Louis XIV. “Certain persons of the greatest influence in Parliament come sometimes to see me, without any lights and muffled in a cloak in order not to be recognized,” says a letter of September 26, 1669, from the Marquis of Ruvigny to M. de Lionne; “they give me to understand that common sense and the public security forbid them to see, without raising a finger, the whole of the Low Countries taken, and that they are bound in good policy to oppose the purposes of this conquest if his Majesty intend to take all for himself.” On the 23d of January, 1668, the celebrated treaty of the Triple Alliance was signed at the Hague. The three powers demanded of the King of France that he should grant the Low Countries a truce up to the month of May, in order to give time for treating with Spain and obtaining from her, as France demanded, the definitive cession of the conquered places or Franche-Comte in exchange. At bottom, the Triple Alliance was resolved to protect helpless Spain against France; a secret article bound the three allies to take up arms to restrain Louis XIV., and to bring him back, if possible, to the peace of the Pyrenees. At the same moment, Portugal was making peace with Spain, who recognized her independence.
