Having watched the failure of the expeditions by which Napoleon had hoped to complete the conquest of Southern Spain, we must turn our eyes northward, to Madrid and the long line of communications which joined the capital to the French base of operations at Vittoria, Pampeluna, and San Sebastian. At the moment when the Valencian and Andalusian expeditions were sent out from Madrid and Toledo, Murat had still under his hand a large body of troops, the second and third division of Moncey’s corps, the second and third of Dupont’s, and the 5,000 horse and foot of the Imperial Guard--in all more than 30,000 men. Bessières, if the garrison of the northern fortresses and some newly arrived reinforcements are added to his original force, had more than 25,000. With these the grand-duke and the marshal had to contain the insurrection in Northern Spain, and to beat back the advance of the army of Galicia. The furthest points to the north and east to which the wave of insurrection had washed up were Logroño and Tudela in the Ebro valley, Santander on the coast of the Bay of Biscay, and Palencia and Valladolid in Old Castile. All these places lay in Bessières’ sphere of action, and he promptly took measures to suppress the rising at each point. On June 2 a column sent out from Vittoria reoccupied Logroño, slaying some hundreds of half-armed peasants, and executing some of their leaders who had been taken prisoners. On the same day a stronger force, six battalions and two squadrons under General Merle, marched from Burgos on Santander. Driving before him the insurgents of the Upper Ebro valley, Merle advanced as far as Reynosa, and was about to force the defiles of the Cantabrian Mountains and to descend on to Santander, when he received orders to return and to take part in suppressing the more dangerous rising in the plains of Old Castile. News had arrived that the captain-general, Cuesta, was collecting a force at Valladolid, which threatened to cut the road between Burgos and Madrid. To deal with him Bessières told off Merle, and another small column of four battalions and two regiments of _chasseurs_ under his brilliant cavalry-brigadier, Lasalle, one of the best of Napoleon’s younger generals. After sacking Torquemada (where some peasants attempted an ineffectual resistance) and ransoming the rich cathedral town of Palencia, Lasalle got in touch with the forces of Cuesta at the bridge of Cabezon, where the main road from Burgos to Valladolid crosses the river Pisuerga. On the eleventh of June Merle joined him: on the twelfth their united forces, 9,000 strong, fell upon the levies of the Captain-general.
