Abaxo on the left, and Outeiro on the right bank, of the Tamega. Soult halted three days at Monterey in order to allow his rearguard and his convoy of sick to close up with the main body. But on March 10 he resumed his advance, using the two parallel roads on the two banks of the Tamega. Franceschi’s light horse and Heudelet’s division pushed down the eastern side, Caulaincourt’s brigade of dragoons[271] and Delaborde’s infantry down the western side of the river. Merle and Mermet were still near Verin. As the Tamega was unfordable in most places, the army seemed dangerously divided, but Soult knew well that he was running little or no risk. Both at Feces and Outeiro the Portuguese detachments, which covered Silveira’s main body, tried to offer serious resistance. They were of course routed, with the loss of a gun and many prisoners. [271] Of Lahoussaye’s division. On hearing that his enemy was drawing near, Silveira ordered his whole army to retreat behind Chaves to the position of San Pedro[272]. This command nearly cost him his life; the ignorant masses of militia and _Ordenanza_ could only see treason in the proposed move, which abandoned the town to the French. The local troops refused to march, and threatened to shoot their general: he withdrew with such of his men as would still obey orders, but a mixed multitude consisting of part of the 12th regiment of the line (the Chaves regiment), and a mass of _Ordenanza_ and militia, remained behind to defend the dilapidated town. Its walls had never been repaired since the Spaniards had breached them in 1762; of the fifty guns which armed them the greater part were destitute of carriages, and rusting away in extreme old age; the supply of powder and cannon-balls was wholly insufficient for even a short siege. But encouraged by the advice of an incompetent engineer officer[273], who said that a few barricades would make the place impregnable, 3,000 men shut themselves up in it, and aided by 1,200 armed citizens, defied Soult, and opened a furious fire upon the vedettes which he pushed up to the foot of the walls. The Marshal sent in a fruitless summons to surrender, and then invested the place on the evening of the tenth; all night the garrison kept up a haphazard cannonade, and shouted defiance to the French. Next morning Soult resolved to drive away Silveira from the neighbouring heights, convinced that the spirits of the defenders of Chaves would fail the moment that they saw the field army defeated and forced to abscond. The divisions of Delaborde and Lahoussaye soon compelled Silveira to give ground: he displayed indeed a laudable prudence in refusing to let himself be caught and surrounded, and made off south-eastward towards Villa Real with 6,000 or 7,000 men. The Marshal then summoned Chaves to surrender for the second time; the garrison seem to have tired themselves out with twelve hours of patriotic shouting, and to have used up great part of their munitions in their silly nocturnal
