The duke waited a few days, then, finding that he could not decoy his wily foe from the walls, broke camp and marched back, proud of having flaunted a challenge in the face of the enemy. He knew not Gonsalvo. The French had not gone far before the latter opened the gates and sent out his whole force of cavalry, under Diego de Mendoza, with two corps of infantry, in rapid pursuit. Mendoza was so eager that he left the infantry in the rear, and fell on the French before they had got many miles away. A lively skirmish followed, though of short duration, Mendoza quickly retiring, pursued by the French rear-guard, whose straggling march had detached it from the main body of the army. Mendoza’s feigned retreat soon brought him back to the infantry columns, which closed in on the enemy’s flanks, while the flying cavalry wheeled in the rapid Moorish style and charged their pursuers boldly in front. All was now confusion in the French ranks. Some resisted, but the greater part, finding themselves entrapped, sought to escape. In the end, nearly all who did not fall on the field were carried prisoners to Barleta, under whose walls Gonsalvo had drawn up his whole army, in readiness to support Mendoza if necessary. The whole affair had passed so quickly that Nemours knew nothing of it until the bulk of his rear-guard were safely lodged within the walls of the Spanish stronghold. This brilliant success proved the turning-point in the tide of the war. A convoy of transports soon after reached Barleta, bringing in an abundance of provisions, and the Spaniards, restored in health and spirits, looked eagerly for some new enterprise. Nemours having incautiously set out on a distant expedition, Gonsalvo at once fell on the town of Ruvo and took it by storm, in spite of a most obstinate defence. On April 28, 1503, Gonsalvo, strengthened by reinforcements, finally left the stronghold of Barleta, where he and his followers had suffered so severely and shown such indomitable constancy. Reaching Cerignola, about sixteen miles from Barleta, he awaited the advancing army of the French, rapidly intrenching the ground, which was well suited for defence. Before these works were completed, Nemours and his army appeared, and, though it was near nightfall, made an immediate attack. The commander was incited to this by taunts on his courage from some hot-headed subordinates, to whom he weakly gave way, saying, "We will fight to-night, then; and perhaps those who vaunt the loudest will be found to trust more to their spurs than to their swords,"—a prediction which was to prove true.
