Such was the first battle fought by British troops in the great cause of the Peninsula: it cost us some valuable lives, among whom Colonel Lake, and Captain Bradford were the most distinguished; but it gave a sample of that bravery and good conduct which have since marked the progress of our arms, and have raised the military renown of England to the glorious eminence on which it at present stands. The advantage which resulted from this action was great. General Loison was marching to join General La Borde, in the position of Roliça; his columns, the next day, were distinctly perceived in the direction of Torres Vedras, to which place he was forced to retire, in consequence of the action of the preceding morning; but if the two corps had been at the battle of Roliça, the British loss must have been considerably greater, and the general operations of the campaign proportionally delayed.

The following day, the 18th, Sir Arthur Wellesley marched the army to Lourinhal, for the purpose of bringing supplies from the shipping, as also to receive the reinforcements which were understood to be upon the coast from England.

The 19th he moved to Vimiera, on which day, the brigade under the orders of General Anstruther, landed, and on the morning of the 20th marched up to the army. Sir Arthur Wellesley had during the last two days supplied his army with provisions, had received part of his reinforcements, and directed the rest which were in the offing, under Major General Ackland, to land in the course of the night; he determined, therefore, to move forward to Mafra, and the orders to that effect were given.

The enemy was known to have collected his force at Torres Vedras; his cavalry had patroled about the British army during the preceding days, without being opposed; the superiority of numbers in that arm was decided.

But Sir Arthur Wellesley conceived that by moving along the coast road to Mafra, he should turn the position which the French occupied, and by that operation force them to retire upon Lisbon. He was also of opinion, that from the rapidity of his own march, he should arrive in the neighbourhood of that town, before the enemy would be able to occupy, with advantage, the ground which would defend it, and upon which he should force them to give him battle. On the evening of this day, however, a frigate, on board which was Sir Harry Burrard, arrived in Marciera Bay; Sir Arthur Wellesley immediately waited on that officer, to receive his orders, and to communicate to him the plans he was about to pursue. Sir Harry Burrard disapproved of them, directed counter orders to be issued to the army, to prevent its march in the morning, and determined to await the arrival of the corps under the orders of Sir John Moore. Sir Arthur Wellesley represented that the French army was now so near, that it was impossible to prevent an action; that the corps under his orders was equal to the contest with it; that the army of Sir John Moore would be of infinitely more service by marching upon Santarem; and that the greatest disadvantage would arise, from our changing at once from an offensive to a defensive line of operations. Sir Harry Burrard remained, however, fixed to his first intention; the counter orders were given, and a messenger was despatched to Sir John Moore, to direct him to move down in his transports, to Marciera Bay. Thus was the whole system of our campaign changed in a moment. With the enemy collected within three leagues of us, we were directed to remain stationary, till a corps of which we had, as yet, no tidings, should arrive.

The event, however, proved what Sir Arthur Wellesley had foretold. At nine in the morning of the 21st, our advanced posts were attacked, and the glorious battle of Vimiera evinced that the British army was worthy of the confidence which its General had reposed in it, in the discussion of the preceding evening.

Early on this day, Sir Arthur Wellesley had been to the advanced posts, and had returned to his quarters, when the first shots were exchanged with the advance of the enemy, who had passed from Torres Vedras, through the defile in front of it, and had been marching during the whole of the night.

Sir Arthur Wellesley had posted the light troops and the 50th Regiment, under Brigadier General Fane, upon a height near a windmill, in front of the village of Vimiera. Brigadier General Anstruther was upon the right of this corps, but a part of his brigade was detached during the action, to occupy Vimiera; the left of the army was placed upon a ridge of heights, which run eastward into the country, and across which the brigades of Major General Ferguson and Major General Nightingale were placed in position. The rest of the army was in reserve, upon heights in rear of Vimiera, which in reality formed the position, the one in which the action was fought being only the advance of it. The French army was divided into two divisions, under Generals La Borde and Loison, and the reserve, composed of the grenadiers and light infantry, together with the cavalry, under General Kellerman.

Junot separated his army, to attack the positions of our right and left at the same moment, connecting his two wings by the force under General Kellerman; they were, however, at too great a distance from each other, and their attacks were unconnected.

The left column was first engaged with the brigade of Brigadier General Anstruther; it attempted to turn his right, but after a contest of some duration, in which the superiority of the British fire, in the first instance, and afterwards of British bayonets, was completely proved, the enemy was repulsed with great slaughter, and forced to abandon his undertaking. The right column (which had moved to the left of the British) began its attack upon the brigades of Major Generals Ferguson and Nightingale, at the time that the left had been beaten by Brigadier General Anstruther. It commenced with considerable vigour, but the steadiness with which it was received, soon stopped its career; in less than half an hour the column was beaten, and pursued beyond the heights; General Bregnier and six guns taken. A French regiment afterwards rallied near the village of Ventoso, at the extremity of the hill, and made an attack, in column of mass, to recover the guns; but it was completely routed, with great loss. The attack upon the village of Vimiera, as the decisive effort, was made by the reserve, in close column, supported by artillery, but was most gallantly resisted by the 50th and part of the 43d Regiments, who charged the flank of the column and totally defeated it. Two squadrons of the 20th Regiment of cavalry moved upon it when broken, and cut down and took prisoners a considerable number of those composing it, who were escaping from the infantry.
