On the 26th Clauzel, finding the pursuit had slackened, sent Colonel Fabvier to advise the king of it, and then sending his own right wing across the Duero, by the ford near Boecillo, to cover the evacuation of Valladolid, marched with the other wing towards the bridge of Tudela; he remained however still on the left bank, in the hope that Fabvier’s mission would bring the king back. Joseph who had already passed the Puerta de Guadarama immediately repassed it without delay and made a flank movement to Segovia, which he reached the 27th, and pushed his cavalry to Santa Maria de Nieva. Here he remained until the 31st expecting Clauzel would join him, for he resolved not to quit his hold of the passes over the Guadarama, nor to abandon his communication with Valencia and Andalusia. But Wellington brought Santo Cildes over the Duero to the Zapardiel, and crossing the Eresma and Ciga rivers himself, with the first and light divisions and the cavalry, had obliged Clauzel to retire over the Duero in the night of the 29th; and the next day the French general whose army was very much discouraged, fearing that Wellington would gain Aranda and Lerma while the Gallicians seized Dueñas and Torquemada, retreated in three columns by the valleys of the Arlanza, the Duero and the Esquiva towards Burgos. [Sidenote: Wellington’s despatch.] The English general entered Valladolid amidst the rejoicings of the people and there captured seventeen pieces of artillery, considerable stores, and eight hundred sick and wounded men; three hundred other prisoners were taken by the Partida chief Marquinez, and a large French convoy intended for Andalusia returned to Burgos. While the left wing of the allies pursued the enemy up the Arlanza, Wellington, marching with the right wing against the king, reached Cuellar the 1st of August; on the same day the garrison of Tordesillas surrendered to the Gallicians, and Joseph having first dismantled the castle of Segovia and raised a contribution of money and church plate retreated through the Puerta de Guadarama, leaving a rear-guard of cavalry which escaped by the Ildefonso pass on the approach of the allied horsemen. Thus the army of the centre was irrevocably separated from the army of Portugal, the operations against the latter were terminated, and new combinations were made conformable to the altered state of affairs; but to understand these it is necessary to look at the transactions in other parts of the Peninsula.
