Among them, Count Pierre de Gruyère, refusing an enormous indemnity for losses at the hands of the Bernois and as ever faithful to his order and to Savoy, took his place with other nobles of his house. Warriors each one by training and tradition, not yet had any fear of defeat chilled their ardor or their courage, nor had they learned the wisdom of concealing their threatened attack upon the growing republic. The citizens of Berne were given ample time to send a messenger to the victorious mountaineers of Morgarten, and this was their reply: "Not like the birds are we who fly from a storm-stricken tree. In trouble best is friendship known. Tell the Bernois we are friendly and will send them aid."
The June sun was setting over the plateau when the nobles desisting from their sports drew up their cavalry, supported by a chosen band of infantry from Fribourg. Retreating before the advance of the latter, the Waldstetten, in the forefront of the Bernese army, sought, as was their custom, an advantageous position for attack. From the heights above the city, with their terrifying war cries, and with the same furious onslaught which had overwhelmed Duke Leopold's glorious horsemen at Morgarten, they fell upon the nobles in a bloody melée in which horses, men and valets perished in a hopeless confusion. Three Gruyère knights were left lifeless on the battlefield and eighty-four others, who thus paid the price of their temerity in thinking to stem the already formidable confederation of citizens and free people in Switzerland. Undeterred by this defeat and continually menaced by the incursions of the Bernois, Count Pierre de Gruyère successfully held them in check, and, no less wise as ruler than he was valorous in war, enlarged the power and extent of his domain by political and matrimonial alliances with the great Romand families of Blonay, Grandson and Oron, as well as with the warlike La Tour Chatillons of the Valais, and with the powerful Wissenbourgs and the semi-royal Hapsburg-Kibourgs of eastern Switzerland. Leaving to his nephews, "Perrod" and "Jeannod," the seigneuries of Vanel and Montsalvens which they had inherited from their father, he shared with them the rule of the people.
