Masséna, as we have seen, was only appointed Commander-in-Chief of the Army of Portugal on April 17, 1810, and did not appear at Valladolid, to take up his charge, till May. The campaign, however, had begun long before under the Emperor’s own directions. There were preliminary operations to be carried out, which could be finished before either the new General-in-Chief or the main body of the reinforcements from beyond the Pyrenees had arrived. These were the repression of the insurgent bands of Navarre, Biscay, and Old Castile, the firm establishment of the line of communications between Salamanca and Bayonne, and the capture of the outlying Spanish fortresses, Astorga and Ciudad Rodrigo, which served as external defences for the Portuguese frontier. ‘Les besoins en Espagne sont successifs,’ wrote the Emperor early in the winter of 1809-10[231], ‘il faut d’abord un corps qui soumette les derrières. Étant en Novembre il serait impossible de réunir tous les moyens avant du commencement de janvier. Et dans cette presqu’île coupée de montagnes les froids et les neiges de janvier ne permettront de rien faire.’ All that he could do before spring would be to send forward Junot’s corps, and the other earlier reinforcements, to positions from which they should be ready to strike, the moment that the fine weather began. With the coming of the new year, when these corps had reached their destined positions, the imperial orders begin to abound in elaborate directions for the extermination of the guerrillas of the Upper Ebro and the Upper Douro[232], orders which led to much marching and counter-marching of the newly arrived troops, but to little practical effect in the way of repression, for skilled leaders like Mina, the Empecinado, and Julian Sanchez, nearly always slipped between the fingers of their pursuers, and on the few occasions when they were pressed into a corner, simply bade their men disperse and unite again at some distant rendezvous. These operations, however, were wholly subsidiary: the actual advance against Portugal only commences with the orders given to Junot in February to concentrate his corps at Valladolid, to hand over the charge of Salamanca and Old Castile to Kellermann’s dragoons and the divisions of the 6th Corps, and then to subdue the whole of the plain-land of Leon, as far as the foot of the Asturian and Galician mountains, including the towns of Benavente, Leon, and Astorga. Bonnet and his division, now as always based on Santander, were already advancing to invade the Asturias, and to threaten Galicia from the east. Ney with the 6th Corps was ordered to draw near to the frontier of Portugal on the side of Ciudad Rodrigo, ‘to inundate all the approaches to that kingdom with his cavalry, disquiet the English, and prevent them from dreaming of transferring themselves back to the south.’ The news of the near approach of the Emperor himself with 80,000 men was to be spread in every direction[233].
