When the whole country-side is up in arms, as it was in Galicia and northern Portugal in the spring of 1809, it is useless to dispatch small bodies of men in search of news. They are annihilated in a few hours: but to make large detachments and send them out on long expeditions, so weakens the main army that it loses its power of further advance. This was the fate of the 2nd Corps after the fall of Oporto. Soult, compelled to seek for information at all costs, had to send one of his four infantry divisions back towards Galicia, to succour Tuy and Vigo and obtain news of Ney, while another marched eastward to the Tras-os-Montes, to look for signs of the advance of Lapisse from Salamanca. When these detachments had been made, the remainder of the army was too weak to resume the march on Lisbon which the Emperor had commanded, and was forced to remain cantoned in the neighbourhood of Oporto. The details of Soult’s disposition of his troops after the fall of Oporto were as follows: Franceschi’s cavalry, supported by Mermet’s division of infantry, were pushed forward across the Douro on the road to Coimbra, to watch the movements of the wrecks of the Bishop’s army, which had retired to the line of the Vouga. Merle’s division and half Delaborde’s remained in garrison at Oporto, while Lorges’ and one brigade of Lahoussaye’s dragoons were kept not far from them, in the open country north of the city, about Villa de Conde and Vallongo. The other brigade of Lahoussaye’s division, supported by Foy’s infantry, was sent out on an expedition towards the Tras-os-Montes, with orders to brush away Silveira and seek for news of the expected approach of Lapisse. Loison was placed in command of this detachment. Finally, Heudelet’s division, which had been guarding the sick and the stores of the army at Braga, was ordered to send on all the _impedimenta_ to Oporto, and then to prepare to march northward in order to relieve Tuy and Vigo, and to get into touch with Ney and the 6th Corps. It was clear that the further movements of the Duke of Dalmatia would depend on the intelligence which Loison and Heudelet might obtain. If Ney should have crushed the Galician insurgents, if Lapisse should be met with somewhere on the borders of Spain, matters would look well for the resumption of the advance on Lisbon. It was also to be hoped that Lapisse would be able to give some information as to the doings of Victor and the 1st Corps. For it was necessary to find out how the Duke of Belluno had been faring in Estremadura, and to know whether he was prepared to co-operate in that general movement against the Portuguese capital which the Emperor had prescribed in his parting instructions from Valladolid.
