Under such grave and urgent circumstances, Francis I. behaved on the one hand with more prudence and efficiency than he had yet displayed, and on the other with his usual levity and indulgence towards his favorites.  Abandoning his expedition in person into Italy, he first concerned himself for that internal security of his kingdom, which was threatened on the east and north by the Imperialists and the English, and on the south by the Spaniards, all united in considerable force and already in motion.  Francis opposed to them in the east and north the young Count Claude of Guise, the first celebrity amongst his celebrated race, the veteran Louis de La Tremoille, the most tried of all his warriors, and the Duke of Vendome, head of the younger branch of the House of Bourbon.  Into the south he sent Marshal de Lautrec, who was more brave than successful, but of proved fidelity.  All these captains acquitted themselves honorably.  Claude of Guise defeated a body of twelve thousand lanzknechts who had already penetrated into Champagne; he hurled them back into Lorraine, and dispersed them beneath the walls of the little town of Neufchateau, where the princesses and ladies of Lorraine, showing themselves at the windows, looked on and applauded their discomfiture.  La Tremoille’s only forces were very inferior to the thirty-five thousand Imperialists or English who had entered Picardy; but he managed to make of his small garrisons such prompt and skilful use that the invaders were unable to get hold of a single place, and advanced somewhat heedlessly to the very banks of the Oise, whence the alarm spread rapidly to Paris.  The Duke of Vendome, whom the king at once despatched thither with a small body of men-at-arms, marched night and day to the assistance of the Parisians, harangued the Parliament and Hotel de Ville vehemently on the conspiracy of the Constable de Bourbon, and succeeded so well in reassuring them that companies of the city militia eagerly joined his troops, and the foreigners, in dread of finding themselves hemmed in, judged it prudent to fall back, leaving Picardy in a state of equal irritation and devastation.  In the south, Lautrec, after having made head for three days and three nights against the attacks of a Spanish army which had crossed the Pyrenees under the orders of the Constable of Castille, forced it to raise the siege and beat a retreat.  Everywhere, in the provinces as well as at the court, the feudal nobility, chieftains and simple gentlemen, remained faithful to the king; the magistrates and the people supported the military; it was the whole nation that rose against the great lord, who, for his own purposes, was making alliance with foreigners against the king and the country.
