Buonaparte reached the head-quarters at Vitoria on the 8th, and immediately pushed forward a corps under Soult against the Extremaduran army in his front. Bessieres commanded the cavalry, which had before proved so fatal to the Spaniards at Rio Seco, and which had now been greatly reinforced. This army, under the Conde de Belveder, had been intended to support Blake, and keep up a communication between his army and that of Castaños. It consisted of about 13,000 men; and their Commander, a young man, although aware that a superior force was advancing against him, waited for the attack in an open ♦NOV. 10.♦ position at Gamonal. He had with him some of the Walloon and Spanish guards, and a few regiments of the line; the rest were new levies, and among them a corps of students, volunteers from Salamanca and Leon. These youths, the pride and the hope of many a generous family, were in the advanced guard. They displayed that courage which might be looked for in men of their condition, and at that time of life: twice they repulsed the French infantry, and when Bessieres with the horse came upon their flank, fell almost to a man where they had been stationed. The loss in killed was estimated at 3000, nearly a fourth of this brave army; the victorious cavalry entered Burgos with the fugitives, and the city, which was entirely forsaken by its inhabitants, was given up to be plundered. Bessieres pursued Count Belveder, while Soult turned aside toward Reynosa, to complete the destruction of Blake’s army. One corps of the French marched upon Palencia, another upon Lerma; from the latter place the Count retreated to Aranda; there also Bessieres pursued, and the wreck of the army collected at Segovia; the piquets of the French were now upon the Douro, and their cavalry covered the plains of Castille. ♦PROCLAMATION EXCLUDING CERTAIN SPANIARDS FROM PARDON.♦
