The royalists in England, who played so deep a stake on the king's account, were not unnaturally desirous that he should risk something in the game, and continually pressed that either he or one of his brothers would land on the coast. His standard would become a rallying-point for the well-affected, and create such a demonstration of public sentiment as would overthrow the present unstable government. But Charles, not by nature of a chivalrous temper, shrunk from an enterprise which was certainly very hazardous, unless he could have obtained a greater assistance of troops from the Low Countries than was to be hoped.[488] He was as little inclined to permit the Duke of York's engaging in it, on account of the differences that had existed between them, and his knowledge of an intrigue that was going forward in England, principally among the catholics, but with the mischievous talents of the Duke of Buckingham at its head, to set up the duke instead of himself.[489] He gave, however, fair words to his party, and continued for some time on the French coast, as if waiting for his opportunity. It was in great measure, as I suspect, to rid himself of this importunity, that he set out on his long and very needless journey to the foot of the Pyrenees. Thither the two monarchs of France and Spain, wearied with twenty years of hostility without a cause and without a purpose, had sent their minister to conclude the celebrated treaty which bears the name of those mountains. Charles had long cherished hopes that the first fruits of their reconciliation would be a joint armament to place him on the English throne: many of his adherents almost despaired of any other means of restoration. But Lewis de Haro was a timid statesman, and Mazarin a cunning one: there was little to expect from their generosity; and the price of assistance might probably be such as none but desperate and unscrupulous exiles would offer, and the English nation would with unanimous indignation reject. It was well for Charles that he contracted no public engagement with these foreign powers, whose co-operation must either have failed of success, or have placed on his head a degraded and unstable crown. The full toleration of popery in England, its establishment in Ireland, its profession by the sovereign and his family, the surrender of Jamaica, Dunkirk, and probably the Norman Islands, were conditions on which the people might have thought the restoration of the Stuart line too dearly obtained.
