But the Escurial and the Vatican were leagued to destroy French influence in Switzerland. Spain gave up hope of compelling the cantons to make a direct alliance with her, but by means of commercial threats and commercial inducements counted on still keeping the Alpine passes open to her arms. Her maxim was, where the grain of Lombardy goes, there Spain’s armies may go, too. To neutralize this danger the French energetically opposed any renewal of an alliance between the Vatican and the Swiss cantons. The Grey League, later won by the commercial promises of Spain, separated from the other two in the end, but its defection was not so serious as it might have been, since according to the joint constitution the vote of two leagues in matters of foreign policy compelled the adherence of the third. But in order further to strengthen the hold of France, the French ambassadors had recourse to a sort of referendum in order to secure an approval of the majority of all the Swiss towns in favor of the French alliance, in addition to the official action of the three leagues. The success of this stroke was complete and the general diet of the three leagues gave its adherence to the treaty of Freiburg concluded by the bishop of Limoges and the marshal Vieilleville on December 7, 1564.[856] The poverty of France, however, seriously endangered the continuance of this alliance. When it was concluded, France tried to stave off payment of her debts, which amounted to more than 600,000 livres, yet demanded the execution of the articles of Freiburg. Glarus, Lucerne, Schwytz, Appenzell, Valais, the Grisons, Schaffhausen, and Basel bitterly complained, the last also because of the burdens laid upon the importations of her commerce into France through Lyons. In this conflict which France carried on against Spain and the Holy See in Switzerland, Charles IX was supported by the German Protestants, who of course were hostile to both houses of Hapsburg, and France may be credited with considerable address in smoothing the ruffled feelings of Basel and Schaffhausen, and softening the Protestant prejudices of Zurich. This is simply another way of saying that the foreign policy of France in Switzerland was a Protestant policy. Even Bern yielded and joined the general treaty of alliance instead of insisting upon a particular treaty, as she had at first done.[857]
