On the 14th the King, accompanied by Bassompierre, Créquy, and Châtillon, left Grenoble with the army which had assembled there and, passing through the Bresse, entered Savoy. The three marshals were to command the army in turn, and the first period of command fell to Bassompierre, who made good use of his opportunities. He took the town and citadel of Chambéry; compelled Rumilly to surrender; and, pushing on with the advance-guard over the difficult roads, turned the flank of the Prince of Carignano, who commanded the main Piedmontese army, and compelled him to beat a precipitate retreat from his strong position at Conflans; and then, crossing the Col de la Louaz, the Col de Nave, the Grand-Cœur and the Petit-Cœur, had occupied Moutiers and the Pas du Ciel, when he received a despatch from the King instructing him to resign his command to the Maréchal de Châtillon, whose turn it was to lead the army. “This offended me extremely,” says the marshal, “since I did not think that, as the same troops would continue to form the advance-guard, my person alone ought to be dethroned, and that having started the hare, another should come to profit by my labours.” However, of course, he had no alternative but to hand over the command to his colleague. But when, on June 4, the King and the Cardinal arrived at Moustier, he “complained of the outrage that had been done him.” However, he got no satisfaction from them, as they decided that the arrangement that had been made at the outset of the campaign must be adhered to. By the third week in June all Savoy had been conquered, with the exception of the citadel of Montmélian, which was being closely blockaded, and Louis XIII and Richelieu returned to Grenoble, whither Bassompierre followed them. On July 10 a division of the army of Piedmont under Montmorency and d’Effiat defeated the forces of Charles Emmanuel at Avigliana and occupied Saluzzo, which the Duke of Savoy had annexed during the troubles of the League and retained at the cost of much sacrifice of territory in 1601.
