THE SIEGE OF SALTO CONTINUED—NIGHT ATTACK ON THE ENEMY'S CAMP—SUCCESSFUL—GENERAL MEDINA APPROACHING—SEND GEN. BAEZ AND ANZANI TO MEET HIM—A GREAT SURPRISE—ALMOST OVERWHELMED BY THE ENEMY—FIGHT TILL NIGHT—RETREAT.

Vergara, with his division, was pressing the town very closely, and some persons acquainted with the country were sent to spy his position, which thus became known to the defenders. It would have been useless to make an attack by day, because it was impossible to surprise them, and, therefore, it was necessary to attack by night. I had given Colonel Baez the command of the cavalry, and Anzani was with the infantry. They left Salto after nightfall, and took the direction towards the enemy's camp, situated about eight miles off. Although the march of the troops was as silent and as cautious as possible, they were heard by the advanced sentinels, and therefore Vergara had time to mount his horse. The assault was made without loss of time, but only the cavalry of the Republicans were able to fight, as the infantry, in spite of all their exertions, could not reach the field of battle in season. The enemy fought with spirit, but at the cry of "The infantry!" which was raised at a favorable moment, they gave ground, and then broke their ranks and took to flight. They were pursued several miles, but, on account of the darkness, little was effected. A few prisoners were made and some horses taken, while there were a small number of killed and wounded on both sides. When daylight appeared, it was difficult to find the field of battle, as the fighting had been done on the march. Several groups of the enemy appeared, scattered on the distant hills, and Colonel Baez remained with the cavalry to pursue them and to collect a herd of oxen, while the other troops returned to Salto.

About that time, which was the beginning of the year 1846, we received news that General Medina, with a number of emigrants from the Oriental, was coming from Corrientes for Salto. The discomfiture of Vergara had given the Republicans an advantage, but had not produced the results that might have been expected. Lamas, who was not far off, and engaged in breaking horses, came up on receiving intelligence of the defeat, and ordered the collecting of men. Both established their camps, and recommenced the siege, driving away the animals. Their superiority in cavalry expedited that proceeding. General Medina then came, who had been appointed head of the army, and it was necessary to secure his entrance. Colonel Baez, as has been mentioned already, had assumed the command of the cavalry, and regularly organized it, skilled as he was in that kind of troops. Being possessed of uncommon activity, he greatly increased the number of horses, and provided the city and the troops with cattle. Mundell and Juan de la Cruz were at his orders, and at that time both were detached, with commissions to catch wild horses. Colonel Baez, better known than General Medina, was in direct relation with him, and knew that he was to be in sight of Salto on the 8th of February; and it was therefore arranged that I should accompany him with the cavalry. At dawn of day on the 8th of February, 1846, we left Salto, and took the direction of the little river San Antonio, on the left bank of which they were to await the approach of General Medina and his army. The enemy, according to their custom in that region, showed several troops of cavalry on the heights on the right, which approached at times as if to observe whether they were collecting animals, and to interrupt them. Colonel Baez stationed a line of marksmen of the cavalry against those troops, and employed himself several hours in skirmishing with them. The infantry had halted near the little stream, at a place called Tapera di Don Vicenzio. I was separated from the infantry, and observing the guerrillas, fighting, conducted by Baez. That kind of warfare afforded the Italians an amusing sight: but the enemy concealed their "wasp's nest" under that kind of military game, having put forward so feeble a force only to deceive their opponents, and give their strong body, which was behind, opportunity to advance.

The country, in all parts of the department of Salto, is hilly, as is also that of San Antonio. Therefore the large force which was advancing was able to approach within a short distance without being discovered.

When I had reached the place of observation, and cast my eyes on the other side of San Antonio, I was overwhelmed with surprise by discovering, on the west of a neighboring hill, where only a few of the enemy had before been seen, a multitude of troops, as was shown by a forest of lances: seven squadrons of cavalry, with banners displayed, and a corps of infantry, double in size of our own, who, having come up on horseback, within two musket shots, dismounted, formed in line of battle, and were marching, at quick step, to charge with the bayonet. Baez said to me: "Let us retire." But, seeing that to be impossible, I replied: "There is not time enough; and we must fight."

I then ran to the Italian Legionaries; and, in order to destroy, or at least to mitigate the impression which might be produced on them by the appearance of so formidable an enemy, said: "We will fight! The cavalry we are resolved to conquer. To-day we have them, although we are a small body of infantry."

At the place where we took position there were numerous wooden posts standing planted in the ground, which had served in the walls of an old wooden edifice; and to each beam was assigned a Legionary. The remainder, forming three small parties, were placed in column behind the building, and covered by walls of masonry of the northern end of the same building, which was in form of a room, capable of containing about thirty men, and covering almost the front of the little column. On the right of the infantry, Baez was posted, with the cavalry, those being dismounted, who were armed with carbines, while the lancers remained on horseback. The whole force comprised about a hundred cavalry, and a hundred and eighty-six Legionaries. The enemy had nine hundred cavalry, (some said twelve hundred,) and three hundred infantry. The Republicans, therefore, had only one thing left that could be done—to defend themselves—resist, and repel the charge of the enemy's infantry. I then ran forward, and gave them all the attention in my power. If the enemy, instead of charging in line of battle, forming an extended line, had charged in column, or in alternate platoons, they must have destroyed our force. By the impetus of their column they would certainly have penetrated into our position, and mingled with the defenders; and then their cavalry would have completed our ruin and exterminated us. Then the fields of San Antonio would have been, to this day, whitened with Italian bones! But, instead of this, the enemy advanced in line, beating the charge, and bravely withholding their fire until within a few yards. The Legionaries had orders not to fire until very near. When the enemy reached the appointed distance, they halted and gave a general discharge. The moment was decisive. Many of the defenders fell under that fire: but the assailants were thrown into disorder, being thinned by shots from the Republicans, who fired from behind the timbers, and then charged them, not in order, but yet in a body, and forced them to turn their backs, by falling upon them with bayonets, like mad-men. That there occurred for the Republicans a moment of disorder and hesitation, it cannot be denied. There were among us a number of prisoners, who, not expecting a successful termination to the desperate defence, cast about their eyes to find some way open for escape. But they were prevented from doing anything, by some of our brave men, who then, at the cry of "The enemy run!" threw themselves upon them like lions.

From the moment when I directed my attention upon the enemy's infantry, I saw nothing more of Colonel Baez and the cavalry. Five or six horsemen remained with my men, whom I put there under the command of a brave Oriental officer, Jose Maria.

After the defeat of the enemy's infantry, I had hopes of safety; and, taking advantage of the momentary calm produced by the stupefaction of the enemy, I put my men again in order. Among the dead remaining on the ground, especially those lying where the enemy halted, we found abundant supplies of cartridges; and the muskets of the killed and wounded served an important purpose, being taken, to arm those of the soldiers who were in want, and some of the officers.

The enemy, having failed in their first charge, repeated it several times, many of their dragoons dismounting; and with them and masses of cavalry, they attacked us, but succeeded only in increasing their loss. I was always ready, with some of the bravest of the Legionaries, who awaited the charge; and, when the enemy had made their attack, invariably charged them in return. The enemy several times endeavored to get a position near us; but I then posted the best marksmen among our soldiers, and made them harrass them, until they took to flight.
