The formation being completed, the columns advanced in the following order:—The 71st and 92d regiments, and 60th rifle company, moved direct upon the village, at quarter-distance, and the 50th in close column, with the artillery a little in rear as a reserve. The right column, having the 39th regiment as a reserve, moved to the right, crossed the plain to the right of the town, in order to cut off the enemy's retreat by any of the roads leading from Arroyo-del-Molinos to Truxillo, Medellin, or Merida. The centre column moved between the other two, and was kept in readiness to act wherever its services might be required. General Morillo, with the Spanish infantry, supported the left column.

The 71st and 92d regiments entered the village at a quick pace, and, at the point of the bayonet, soon cleared it of the enemy, who were quite unprepared for such an unceremonious visit. One brigade of the French infantry had unfortunately marched from Arroyo to Medellin previous to our arrival, and the others were filing out of the village for a similar purpose, when the British huzza fell on their ears, and arrested their progress. Finding it totally impossible to escape without giving battle, Gerard faced to the right-about, and made the best disposition in his power for a determined resistance. The infantry he formed into two squares, on the roads leading to Merida and Medellin. The right square was posted not more than one hundred yards from the village,—the other was at a greater distance, and had its left flank protected by their cavalry. On arriving at the eastern extremity of the principal street, the 71st moved to their left—lined some of the village garden walls, and peppered their antagonists in very good style. The 92nd regiment following close on the heels of their companions, filed to the right, formed line, prepared to charge, but were not permitted to fire a single shot. This was extremely galling to the soldiers, who saw their officers and comrades falling around them without daring to retaliate upon the enemy. This was no doubt an unpleasant situation to be placed in, but knowing that the success of an enterprise frequently depends on the manner in which orders of this description are attended to, the Highlanders, with a praise-worthy forbearance, resisted every temptation to commit a breach of their orders, and with a patience not very peculiar to their countrymen, waited the arrival of the decisive moment.

During the time occupied by the 92nd regiment in completing their new formation, the three pieces of artillery were brought forward, and on being posted on our right, fired with terrible effect on the enemy's masses, carrying death into their thickest ranks. In a few minutes the French troops appeared extremely uncomfortable, and in a few more something like a wavering in their squares was observable. The moment so anxiously looked for having now arrived, the Highlanders moved forward to the charge, but the French declined the honour intended for them, wheeled to the right-about, and with rather a hasty step retired towards a steep hill in their rear, over which their general fancied he should be able to conduct them to more comfortable quarters.

Pending these operations against the enemy's right, General Howard manœuvred round their left, and after cutting off their retreat upon Merida and Medellin, endeavoured to interpose his whole force between the enemy and the mountain in their rear. Our cavalry were also very actively employed. On perceiving it to be General Gerard's intention to gain the rock with his mixed force, they advanced, cut off the French cavalry from their infantry, charged them repeatedly, routed them, and captured all their artillery. These movements reduced the French general to the choice of two very bad alternatives—unconditional surrender, or a hazardous flight across the mountains. Giving a preference to the latter, he retired upon the most inaccessible point of the hill, which his troops ascended, and then fired down upon us from behind the rocks, with which the whole face of it was thickly covered. To prevent the enemy from reaping all the advantages which he anticipated from this movement, General Howard pushed them closely with the 28th and 34th regiments, and detached the 39th, and Colonel Ashworth's Portuguese, round the eastern corner of the mountain, to charge the fugitives in flank. The left column also kept close to the enemy on their retreat; and the Spaniards prepared to ascend the hill considerably to our left, to assist in the capture of the flying host. By these various movements, the latter became so sensible of their own inability to continue the conflict, but at a very unnecessary sacrifice of human life, that after throwing away their arms, or rendering them useless, they attempted to escape from our toils; but the great proportion seeing that to be impossible, a white flag was at length hoisted on the point of a sword, in token of submission. The remainder continuing their retrograde movement across the mountain, and the British troops being much in want of repose, General Hill gave over the pursuit of the fugitives to General Morillo, who followed them twenty miles—killed a number, and made many prisoners.

Our loss in this admirably conducted affair, was extremely trifling, compared with that of the enemy. We had only seven killed, fifty-seven wounded, and one officer, Lieutenant Strenuwitz, aid-de-camp to Sir William Erskine, missing.—That of the French, consisted of one general (Brun), Colonel the prince D'Aremberg, two lieutenant-colonels, an aid-de-camp of General Gerard's, thirty other officers, and from thirteen to fourteen hundred non-commissioned officers and soldiers prisoners. The whole of their artillery, money, baggage, and provisions, also fell into our hands. Their loss in killed must have been severe, for besides those who fell in action, Morillo found upwards of six hundred dead in the woods and mountains, when in pursuit of the remains of this little army, which in the action and pursuit, was reduced from 3100 to 300, who with their wounded chief, effected their escape.

The 18th regiment of Portuguese infantry, and Brigadier-General Campbell's brigade of Portuguese infantry, having joined us at the close of the action, these corps, together with General Long's brigade of cavalry, and the 50th, 71st, and 92nd regiments of British infantry, quitted the field of battle, immediately after the prisoners, &c. were collected, and moved forward to St Pedro, two leagues from Arroyo-del-Molinos.

We had not been long in camp, before a party of twenty-three French dragoons were observed scampering across the plain in our front, in the direction of Medellin. As no time was to be lost, one of our cavalry piquets, consisting of seventeen men, dashed across the plain to intercept them. In a few minutes the two parties stood in the presence of each other, and without much ceremony, proceeded to business. The action, however, was of short duration, for the enemy, after a feebler resistance than was anticipated, agreed to accompany our dragoons into camp, where they were received with three hearty cheers. Both parties being in full view the whole time, the scene was altogether extremely interesting.

At three o'clock in the morning of the 29th, we quitted our bivouac at St Pedro, and after a march of fifteen hours, under torrents of rain, entered Merida, wet, weary, and hungry. The following day being one of rest, all the horses, mules, and asses, captured on the 28th, were sold by auction in the square of Merida, the produce of which, together with the money found in Gerard's military chest, was ordered to be divided at a subsequent period amongst the troops actually engaged on that day.

Our mission into Estremadura being ended, the whole of the troops in Merida, retired on the 31st to Montejo, and on the 1st of November, to Campo Major. The distance being fully seven leagues, we marched two hours before day-break, and at twelve o'clock, halted to refresh the soldiers. Having a few minutes before crossed a deep, rapid, narrow river, which struck some of our men a little under the arm-pits, our situation at the time was not very comfortable. However, a two hours rest, before a rousing fire, aided by a glass of grog, and the rays of a powerful sun, soon banished all traces of our ducking. In high spirits, therefore, we quitted our temporary bivouac. But we had not proceeded above four hundred yards, before another river, broader, deeper, and more rapid than the other, crossed our path, and again drenched us to the neck. How we came to halt in such a position, none could form any notion; but all were agreed, that however amusing the spectacle of a few thousand men standing in water to the neck may be to members of the Quarter-Master General's department, those individuals must be told that mistakes such as this cannot be tolerated, for to the weary, and but too often heated pedestrians, duckings such as those just mentioned, are the prolific sources of almost every disease, which on service, hurries the young soldier into a premature grave.

We remained in Campo-Major on the 2nd of November, and on the 3rd moved to Arronches, an old fortress, the walls of which seemed tottering to their base. Resuming our retrograde movement next morning, we re-entered Portalegre about one o'clock, amid the loud acclamations of a grateful and delighted populace. Satisfied that the spontaneous and grateful effusions of the multitude on this occasion, flowed from hearts untainted with hypocrisy, we received them as a people's thanks—the noblest reward a soldier can receive.
