The two armies were of pretty equal strength: they had each from twenty to five and twenty thousand infantry, French, Germans, Spaniards, lanzknechts, and Swiss. Francis I. had the advantage in artillery and in heavy cavalry, called at that time the gendarmerie, that is to say, the corps of men-at-arms in heavy armor with their servants; but his troops were inferior in effectives to the Imperialists, and Charles V.’s two generals, Bourbon and Pescara, were, as men of war, far superior to Francis I. and his favorite Bonnivet. In the night between the 23d and 24th of February they opened a breach of forty or fifty fathoms in the wall around the park of Mirabello, where the French camp was situated; a corps immediately passed through it, marching on Pavia to re-enforce the garrison, and the main body of the imperial army entered the park to offer the French battle on that ground. The king at once set his army in motion; and his well-posted artillery mowed down the corps of Germans and Spaniards who had entered the park. “You could see nothing,” says a witness of the battle, “but heads and arms flying about.” The action seemed to be going ill for the Imperialists; Pescara urged the Duke of Bourbon and Lannoy, the Viceroy of Naples, to make haste and come up; Lannoy made the sign of the cross, and said to his men, “There is no hope but in God; follow me and do every one as I do.” Francis I., on his side, advanced with the pick of his men-at-arms, burst on the advance-guard of the enemy, broke it, killed with his own hand the Marquis of Civita-San-Angelo, and dispersed the various corps he found in his way. In the confidence of his joy he thought the victory decided, and, turning to Marshal de Foix, who was with him, “M. de Lescun,” said he, “now am I fain to call myself Duke of Milan.” But Bourbon and Pescara were not the men to accept a defeat so soon; they united all their forces, and resumed the offensive at all points; the French batteries, masked by an ill-considered movement on the part of their own troops, who threw themselves between them and the enemy, lost all serviceability; and Pescara launched upon the French gendarmerie fifteen hundred Basque arquebusiers, whom he had exercised and drilled to penetrate into the midst of the horses, shoot both horses and riders, and fall back rapidly after having discharged their pieces. Being attacked by the German lanzknechts of Bourbon and Freundsberg, the Swiss in the French service did not maintain their renown, and began to give way. “My God, what is all this!” cried Francis I., seeing them waver, and he dashed towards them to lead them back into action; but neither his efforts, nor those of John of Diesbach and the Lord of Fleuranges, who were their commanders, were attended with success. The king was only the more eager for the fray; and, rallying around him all those of his men-at-arms who would neither recoil nor surrender, he charged the
