Lord Wellington, who had been present while mass was celebrated for his victory,[195] without delay commenced his march southward, and moved as rapidly as he could, in the vain hope of overtaking the enemy’s rear-guard. Clausel, intending to join the army of the North, fell back on Arivalo; but Joseph Buonaparte, on learning Marmont’s defeat, had retreated himself--and thus Clausel was obliged to change his line for that of the Camino Real, in order to cross the Duero at Tudela. There, too, he failed in effecting his expected junction with the troops that had garrisoned Madrid; and, abandoning his hospitals at Valladolid, he fell back at once on Burgos. The British advance was unopposed. Everywhere the conquerors were received with _vivas_; while fruit, wine, and all the refreshments they could command, were liberally supplied them by the Spanish peasantry. At Valladolid, all hope of coming up with Clausel ended; and Lord Wellington halted on the 30th of July, to enable the rear to close up. Then turning at once, he quitted his previous route, and took the road to the capital. Nothing impeded the victor’s march as he moved direct on Madrid. On the 6th of August, Wellington halted at Cuellar, leaving Clinton’s division there, with the regiments that had suffered on the 21st most severely, to observe any movement that Marmont’s corps might make. Next morning he moved upon the capital, while Hill’s division marched on Zafra. Nothing checked Lord Wellington’s movement on Madrid. On the 7th of August, he reached Segovia; and on the 9th, San Ildefonso,[196] the magnificent summer residence of the Spanish monarchs. There he halted to allow his right to come up; and among the exquisite groves and gardens that had formed a favourite retreat to a kingly race for centuries, the conquerors of Salamanca rested. On the 11th the march was resumed; and as the passes of the Guadarama were undefended, the allies entered New Castile without any opposition, and halted within a march of Madrid. After a careful _reconnaissance_ in company with his lieutenant, Marshal Jourdan, Joseph Buonaparte declared that the capital was untenable, and retreated on Aranguez, after leaving a garrison in the Retiro.[197]
