General Dupont had not been reinforced. He did not know whether his couriers had arrived, many having been already intercepted by the robbers of the Sierra Morena; he knew of the rising of the St. Roque troops, and of the treachery of the Swiss regiments recently engaged in the insurrection; and finding himself threatened on the right by the insurgent army of Andalusia, and on the left by the army of Granada, he resolved to fall back upon the Guadalquivir, and on the 18th June took up his position in the small town of Andujar, to wait for the divisions which he had sent for. That of Vedel was already on its march. Marshal Moncey had failed before Valencia, and could not commence the investment for want of siege guns; he had brought back his division in good condition, and effected his junction with General Frère at San Clemente. Marshal Bessières advanced at the same time against Don Gregorio de la Cuesta, and against General Blake, a descendant of English Catholic refugees. Their forces were considerable, and composed of old soldiers; they had, however, asked for time to prepare their troops and had been forced by the Junta of the Corogne to march to battle. On the evening of the 13th July, the Spaniards, badly informed as to the march of the French, were formed in two lines on the plateau of Medino de Rio-Seco, not far from Valladolid. Attacked one after the other by Marshal Bessières, the two lines were completely beaten and put to flight, not without some resistance at certain points. The slaughter was terrible. General Mouton, at the head of two regiments with fixed bayonets, entered the town of Medina, which was sacked. Marshal Bessières again took the road towards Leon, sweeping before him the disbanded remains of the Spanish army. King Joseph had just entered Madrid.
