Delaborde had executed his orders to check the advance of the British with a zeal and ability that added greatly to his military reputation. Junot, in the interim, was actively engaged in concentrating his brigades, and drawing every disposable man from his garrisons, to enable him to bring a force to bear against the British, that, from its superior formation, must ensure success. His whole corps was formed into two divisions; Delaborde commanding one, and Loison the other, while the reserve, composed entirely of grenadiers, was entrusted to Kellerman. All his dispositions having been completed, the Duke of Abrantes advanced to Vimiero, where he had ascertained that his enemy was halted. Sir Arthur was awakened at midnight by a German officer in charge of the outlying picket, with the intelligence of Junot’s movements, and an assurance that an attack was certain, as the French advance was not above a league distant. Patrols were immediately sent out; and while every care was taken against surprise, the line was not alarmed, nor the men permitted to be disturbed. Junot quitted his position on the evening of the 20th, and marched all night by roads bad in themselves, and interrupted by numerous defiles; consequently great delay occurred, and it was seven o’clock next morning, when he arrived within four miles of the British outposts. The formation of his columns was effected unseen, as the broken ground behind which he made his dispositions, entirely concealed his movements. The first intimation of a serious attack was only given when a mass of Junot’s cavalry deployed in front of the picket that was observing the Lourinho road. Perceiving instantly the point on which the French were about to direct their column, Sir Arthur crossed the ravine with the brigades of Ferguson, Nightingale, Aucland, and Bowes, thus securing his weakest point--the left--before Junot had made a demonstration against it. Presently the enemy’s columns came on; the right by the Lourinho road, and left marching on the plateau, occupied by the 50th and rifles. The onset of both divisions was made with the usual impetuosity of Frenchmen, and in both the British skirmishers were driven in. The British right was furiously attacked. Unchecked by the light troops covering the line, the French came boldly forward, until it found itself directly in front of the 36th, 40th, and 71st. It deployed instantly, and several volleys of musketry were mutually returned, and at a distance so close as to render the effect murderous. But the fusilade was ended quickly; the 82nd and 29th pushed forward, and joined their comrades when pressed by an enormous superiority. “Charge!” was the order; and a cheer, “loud, regular, and appalling,” announced that Britain was coming on.
