It was this last fact that restrained King Joseph from following up his pursuit of the wrecks of the Spanish army to the Sierra Morena, and the gates of Seville, on the morning after Ocaña. To make up the host that had defeated Areizaga, and the other smaller force that was dealing with Del Parque in Leon, the King had been forced to concentrate all his divisions, and the consequence had been that the control of the broad tracts behind him had been lost. We have already had occasion to mention[114] that throughout Old Castile and Leon, the open country was now in the hands of the guerrilleros, who had been growing in force and numbers ever since the time of Talavera, and had risen to the height of their confidence after the day of Tamames, and Del Parque’s repeated occupation of Salamanca. Navarre, and many parts of New Castile were equally disturbed, and Aragon, which Suchet had tamed during the autumn, was beginning once more to move. There were no French troops in the disturbed regions save scanty garrisons at Burgos, Valladolid, Benavente, Avila, Segovia, Guadalajara, Palencia, Tudela, Tafalla, and a few other strategic points. These were cut off from each other, and from Madrid, save when a governor sent out his messenger with an escort many hundreds strong, and even such a force had often to fight its way through half a dozen bands before reaching its destination. The garrisons themselves were not always safe: so powerful were the bands of some of the guerrillero chiefs that they aspired to waging regular war, and did not confine themselves to blocking the roads, or intercepting couriers and convoys. The Empecinado, whose sphere of activity lay on the borders of Old and New Castile, got possession of Guadalajara for a day, though he retired when reinforcements from Madrid were reported to be approaching. Somewhat later, the younger Mina--‘the Student,’ as he was called to distinguish him from his more celebrated uncle Espoz, stormed the town of Tafalla, and shut up the remains of its garrison in its castle, while the flying-columns of the governor of Navarre were seeking him in every other direction. He too, like the Empecinado, had to seek safety in retreat and dispersion, when his exploit drew in upon him forces sent from Suchet’s army of Aragon. [114] See page 83.
