But the Huguenots went too far in their suspicion of the government. Beza, at the synod of La Ferté-sous-Jouarre had been apprehensive of a joint attack of France and Savoy upon Geneva, not knowing that the French aim was to renew the alliance with the Catholic cantons in order to prevent Spanish ascendency there.[854] Bern and Zurich were the pillars of French ascendency in the Alpine country. France counted upon them more than upon all else to prevent Spanish recruiting, and to close the Alpine passes to Spain’s army. To this end Bellièvre, the marshal Vieilleville, and the bishop of Limoges, who had returned from Madrid, where he was succeeded by St. Sulpice, were sent into Switzerland in the early spring of 1564 to penetrate the designs of Spain, and to promise an early payment of the French debts due to the cantons in return for their military support in the wars of Henry II.[855] Bellièvre’s particular mission was to the Grisons. The position of the Grisons was a precarious one, for Spain could attack them from the Valteline, or starve them by prohibiting the exportation of grain into the country from Lombardy. By using such threats the Spanish governor of Milan hoped to compel the adherence of the Grisons to a treaty which would open to Spanish and imperial arms the great Alpine routes of the Splügen, the Bernina, and the Stelvio, thus connecting the territories of the two branches of the Hapsburg house and shutting France out from eastern Switzerland. Bellièvre fraternized with the popular element, and by May, 1564, had almost completely neutralized the success of his Spanish rival in spite of Spanish gold. Fortunately for France the Ten Jurisdictions declared in her favor and the Grisons, though very Spaniardized, luckily had a French pensioner as its chief magistrate, the Swiss captain Florin. Meanwhile the negotiations of the bishop of Limoges and the marshal Vieilleville had progressed so far that the treaty of alliance was all but signed. Late in October Bellièvre received from Freiburg the text of the articles of alliance which the bishop of Limoges and the marshal Vieilleville proposed to submit to the Swiss diet. Encouraged by this success, he went to Glarus in order to overcome the influence of the Zurich preachers who were outspoken enemies of the French alliance, and if possible to settle the difference between that state and Schwytz. By great dexterity he prevailed upon the two cantons to accept a uniform treaty. But he could not push negotiations to a conclusion until hearing from his colleagues. Spain made a supreme effort to secure the opening of the passages between the Tyrol and the Milanais, but failed because the Grisons promised France that they would accept the principle of a renewed alliance, leaving the settlement of details pending, so that although the supremacy of France in Switzerland was not absolutely assured, at least the adherence of the three leagues to her seemed assured.
