Our celerity was of much importance; for, as has already been mentioned, the enemy were in expectation of a strong reinforcement; and that was the entire force of General Urquiza, which had just before been victorious at India Muerta, and was then on the march for Corrientes, to fight the army of that province. Vergara, who had the vanguard of it, came in sight of Salto the day after our return, and captured a few of our horses, which were dispersed in the neighboring pastures. Being in the presence of those forces, which seemed to overwhelm us, we made every exertion to resist it. A battery, marked out by Anzani, in the centre of the city, made a progress that was quite astonishing. Both soldiers and people worked at it, such houses as were adapted to defence were fortified, and every man had a post assigned him. Several cannon were levelled from the boats, and preparations were made to supply the battery. At that time arrived Colonel Baez, with about sixty cavalry. Urquiza soon after presented himself, who had assured his friends that he would cross the Uruguay at Salto, with the assistance of the Republican flotilla, which he expected to capture. But his prediction was not fulfilled. The attack by the enemy was simultaneous with his appearance. ------------------------------------------------------------------------ CHAPTER XXVI. URQUIZA BESIEGES US IN SALTO, WITH ALL HIS FORCES—OUR DEFENCES INCOMPLETE—A SUDDEN ATTACK—REPULSED SORTIES—BOLD OPERATION ON THE OPPOSITE BANK OF THE RIVER—SURPRISING FEATS OF THE HORSEMEN—THEIR HABITS. On the east of Salto was a hill, distant a musket shot from the first houses; and it commanded the whole town. The Republicans had not fortified it, for the want of sufficient force, as it would be necessary, if occupied, to establish a line of fortifications proportioned to the number of disposable troops. As might have been expected, Urquiza took possession of the hill, and placed on it six pieces of artillery. At the same time he sent forward his infantry, at quick step, against the Republican right. Just at that moment two pieces had been placed in the battery: but there was yet neither platform nor parapet; and the enemy, after giving their fire, threw themselves upon the ground, which was not even consolidated. The Republican right was really the most vulnerable, as the enemy could reach it under cover, in the hollow of a valley. And this they did; so that the defenders saw them appear suddenly, and without warning, from that concealment. Immediately the right wing fled, and those occupying the houses retreated towards the river.
