Despite the failure of the marriage alliance, France still had two strings to the Ulysses bow she was drawing against Spain—support of the Dutch, and the union of France by means of the marriage of Henry of Navarre and the princess Marguerite. Spain’s suspicions that the Huguenot naval preparations at La Rochelle were in favor of the Dutch[1504] had not been based on groundless suspicion. William of Orange’s own brother, Louis of Nassau, had remained in France after the Peace of St. Germain, urging an alliance between France and England against Spain,[1505] or else French intervention in the Netherlands.[1506] The count of Nassau enlarged upon the vast designs of the Spanish monarch and showed how sinister they were to France as well as Holland, artfully alluding to the peace of Cateau-Cambrésis, “a peace dishonorable to France;” he dwelt upon the tyranny of Alva and the horrors of the inquisition; he demonstrated that all the inhabitants of the Low Countries, both Catholics and Protestants, hated the Spanish domination; that all the maritime towns were ready to receive French and Dutch garrisons, if but those of Spain could be driven out; that with the sea-power of France thrown into the scale, the Dutch could conquer Spain; and finally proposed the formation of an international league to overthrow Spain, and asserted that France might acquire Flanders and Artois and the empire Brabant, Guelders, and Luxembourg as reward of their services. So alluring was the prospect portrayed to Charles IX that he almost cast off the mask he wore of pretended friendship for Spain.[1507] He told Philip’s minister, Alava, than whom “there was no prouder man or one more disdainful in countenance”[1508] when the ambassador complained to the French King that certain ships of the prince of Orange were being harbored at La Rochelle,[1509] that “his master should not look to give laws to France.”[1510] Meantime the proposed marriage of Henry of Navarre to Marguerite, the King’s sister, progressed. A full year before the nuptials were concluded, the jewels and apparel for the ceremony were already provided. The difficulty of arranging a religious form for the ceremony acceptable to both Catholics and Protestants was the great hindrance.[1511]
