When sudden irregularities of the surface disturbed the order of a column, it halted until the distances were corrected, and then marched silently on with the coolness of a review. Presently the light troops became engaged, the centre broke into columns of regiments, while the left pressed forward rapidly, and the rifles, on the right, bore down on the tirailleurs. Delaborde’s position was now critical, for Ferguson, topping the heights, threatened his rear. But the French general acted promptly—he abandoned the plain, and falling back upon the passes of the Sierra, took up a new position less assailable than the former one; and, from the difficult nature of the mountain surface, requiring, on Sir Arthur’s part, a new disposition of attack.
Five separate columns were now formed, and to each a different pass was allotted. The openings in the heights were so narrow and difficult, that only a portion of the columns could come into fire. The pass on the extreme right was attacked by the Portuguese; the light troops of Hill’s brigade and the 5th regiment advanced against the second; the centre was to be carried by the 9th and 29th, the fourth by the 45th, and the fifth by the 82nd.
Unfortunately the front attack was made either too soon, or difficulties had delayed the flanking corps—and, in consequence, the passes were all stormed, before Delaborde had been even aware that he was endangered on his flank and rear. Regardless of the ground, than which nothing could be more formidable, the assailants mounted the ravines. Serious obstacles met them at every step—rocks and groves overhung the gorges in the hills—and where the ground was tolerably open for a space from rocks, it was covered thickly with brushwood and wild myrtle. Thus the order of the column was deranged; while a broken surface concealed the enemy, and suffered the French to keep up a withering fusilade on troops who had not leisure to return it.
The centre pass, on which the 29th and 9th were directed to advance, was particularly difficult. The 29th led, and the 9th supported it. Entering the gorge undauntedly, the leading companies were permitted to approach a ravine, with precipitous rocks on one side and a thick myrtle wood on the other. From both a tremendous fire was unexpectedly opened. In front and on the flanks, the men fell by dozens; and, as the leading company was annihilated, the column, cumbered by its own dead and wounded, was completely arrested in its movement. But the check was only momentary. Colonel Lake, who led the regiment on horseback, waved his hat and called on the men to follow. A wild cheer was returned, and a rush made up the pass. Notwithstanding the sustained fusilade on every side, the forward movement was successful—and after overcoming every attempt to repel their daring charge, with diminished numbers the 29th crowned the plateau.
But the enemy were not to be easily beaten. Before the 9th could clear the pass, or the 29th form their line, a French battalion advanced and charged. They were most gallantly received; a severe contest ensued; and, after a mutual slaughter, the enemy were repulsed. With increased numbers, again and again the charges were repeated and repelled. At last the 9th got into action; and the head of the 5th regiment began to show itself as it topped the summit of the second pass. On every point the attacks had been successful, and to save himself from being cut off, Delaborde retired in perfect order; and from the difficulty of the ground and his superiority in cavalry, although pressed by the light troops, effected his retreat with little molestation.
This brilliant affair, from the strength of their position, and the obstinacy with which the French contested every inch of ground, cost the British a heavy loss. Even, when forced from the heights, Delaborde attempted to take a new position, and hold the village of Zambugeira. But he was driven back with the loss of three guns—and retreating through the pass of Runa, by a long night march, he gained Montecheque next day.
The French casualties in killed, wounded, and prisoners amounted to a thousand men, and the British to about half that number. Delaborde was among the wounded, and Colonel Lake in the return of the killed.
Delaborde’s defeat having left the road to Torres Vedras open, Sir Arthur pursued the French to Villa Verde, where the British halted for the night, and, cheered by his opening success, the British leader seemed determined to improve it. Orders were accordingly issued to prepare for a rapid march next day, and “it seemed as if no check would be given to the ardour of the troops till they should have won a second victory.” But despatches were received that night, announcing the arrival of General Anstruther with a reinforcement of troops and stores. The fleet were reported to be at anchor off Peniche; and, to cover the disembarkation, and unite himself with the corps on board the transports, Sir Arthur’s march was directed on Lourinho. There the British bivouacked that night, and on the next morning took a position beside the village of Vimiero.
