Retreating, Coligny was joined by Montgomery, fresh from that terrible massacre of Orthez, before which St. Bartholomew itself pales, three thousand Catholics having been butchered, without regard to age or sex, and the river Gave being actually dammed up by the bodies of the Catholics. The indecisive action of Arnay le Due led to negotiations resulting in the treaty of St. Germain, August, 1570.
These treaties are differently viewed. The proposal for them always came from the court, and followed every victory gained by the Catholic party. White would make them out to be traps laid by Catharine; Gandy seems to lean to the same solution in attributing them to her, though he makes her object to have been to prevent the Guises from being complete masters.
But may we not suppose the Catholic party sincere in their wish for peace? They were never first to take up arms; they were unorganized; the court was wavering, and always contained a number of secret allies of the Huguenot cause. That the Huguenot leaders, after a defeat, should through these raise a peace party at court would be a matter of course. The peace gave them all they needed--time to prepare for a new campaign.
Charles IX. was sincere in his wish to make the treaty of St. Germain a reality. In the interval of tranquillity he married, and turned his thoughts to foreign affairs, proposing to aid the Netherlands against the King of Spain. But the Huguenot leaders kept together in the strong city of Rochelle, ready for prompt action. At last, however, Coligny, in September, 1571, repaired to court, where he was received by Charles with great cordiality. Two marriage schemes were now set on foot to strengthen the Protestant cause--the marriage of Henry of Navarre with Margaret, sister of Charles IX., and the marriage of his brother, D'Alençon, to Queen Elizabeth. Even Jane, Queen of Navarre, came to Blois to negotiate in regard to the marriage of her son.
Coligny so far gained Charles that a French force took Mons, and an army under Genlis, marching to that place, was defeated by the Spaniards, under Don Federigo de Toledo. The marriage of Henry took place on the 18th of August, and seemed to confirm Coligny's paramount influence at court.
