That affair was a very singular and curious one, and performed in full view from Salto. The horses of Entre Rios are generally esteemed; and, for good reasons, that capture excited a desire to attack the besiegers. ------------------------------------------------------------------------ CHAPTER XXVII. 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.
