Meanwhile Heudelet’s communication with Oporto had been interrupted, for the Portuguese, routed on the Lima a week before, had come back to their old haunts, seized Braga, and blocked the high-road and the bridges. Soult only got into touch with his expeditionary force by sending out Lahoussaye with 3,000 men to reopen the road to the North. When this was done, he bade Heudelet evacuate Valenza (whose fortifications turned out to be in too bad order to be repaired in any reasonable space of time), and to disperse his division in garrisons for Braga, Viana, and Barcelos. The whole of the convoy and the sick from Tuy were sent up to Oporto. The net result of Heudelet’s operations was that the Marshal, at the cost of immobilizing one of his four infantry divisions, obtained a somewhat precarious hold upon the flat country of Entre-Douro-e-Minho. The towns were in his hands, but the _Ordenanza_ had only retired to the hills, and perpetually descended to worry Heudelet’s detachments, and to murder couriers and foraging parties. Meanwhile 4,000 men were wasted for all purposes of offensive action. Vigo, Tuy, and Valenza had all been abandoned, and touch with the army of Galicia had been completely lost. Even this modest amount of success had been denied to Soult’s second expedition, that which he had sent under Loison towards the Tras-os-Montes. The enemy with whom the French had to deal in this region was Silveira, the same officer who had been defeated between Monterey and Chaves in the early days of March, when the 2nd Corps crossed the Portuguese frontier. He had fled with the wrecks of his force towards Villa Real, at the moment when Soult marched on Braga, and the Marshal had fondly hoped that he was now a negligible quantity in the campaign. This was far from being the case: the moment that Silveira heard that the French had crossed the mountains and marched on Braga, he had rallied his two regular regiments and his masses of _Ordenanza_, and pounced down on the detachment under Commandant Messager, which Soult had left in garrison at Chaves. This, it will be remembered, consisted of no more than a company of infantry, a quantity of convalescents and stragglers, and the untrustworthy Spanish-Portuguese ‘legion,’ which had been formed out of the prisoners captured on March 6 and 12[316]. On the very day upon which Soult was routing Eben in front of Braga, Silveira appeared before the walls of Chaves with 6,000 men. Messager retired into the citadel, abandoning on the outer walls of the town a few guns, which the Portuguese were thus enabled to turn against the inner defences. After a siege of five days and much ineffective cannonading, the governor surrendered, mainly because the native ‘legion’ was preparing to open the gates to Silveira. Twelve hundred men were captured, of whom only one-third were Frenchmen capable of bearing arms, the rest being sick or ‘legionaries.’
