"The army arrived at their camp in the vicinity of Monterey about noon September 19th. That afternoon the general endeavored by personal observation to get information of the enemy's position. He, like Gen. Taylor, saw the importance of gaining the road to Saltillo, and fully favored the movement of Gen. Worth's division to turn their left, &c. Worth marched Sunday, September 20th, for this purpose, thus leaving Twiggs' and Butler's divisions with Gen. Taylor. Gen. Butler was also in favor of throwing his division across the St. John's river, and approaching the town from the east, which was at first determined upon. This was changed, as it would leave but one, and perhaps the smallest division, to guard the camp, and attack in front. The 20th the general also reconnoitered the enemy's position. Early the morning of the 21st the force was ordered out to create a diversion in favor of Worth, that he might gain his position; and before our division came within long range of the enemy's principal battery, the foot of Twiggs' division had been ordered down to the northeast side of the town, to make an armed reconnoisance of the advanced battery, and to take it if it could be done without great loss.

As further ordered, the Ohio regiment was detached from Quitman's brigade, and led by the general (at this time accompanied by Gen. Taylor) into the town. Quitman carried his brigade directly on the battery first attacked, and gallantly carried it. Before this, however, as we entered the suburbs, the chief engineer came up and advised us to withdraw, as the object of the attack had failed, and if we moved on we must meet with great loss. The general was loath to fall back without consulting with Gen. Taylor, which he did do--the general being but a short distance off. As we were withdrawing, news came that Quitman had carried the battery, and Gen. Butler led the Ohio regiment back to the town at a different point. In the street we
