This portion of our line having given way, and the enemy appearing in overwhelming force against our left flank, the light troops which had rendered such good service on the mountain were compelled to withdraw, which they did, for the most part, in good order. Many, however, were not rallied until they reached the depot at Buena Vista, to the defense of which they afterward contributed. Colonel Bissel's regiment, (2d Illinois,) which had been joined by a section of Captain Sherman's battery, had become completely outflanked, and was compelled to fall back, being entirely unsupported. The enemy was now pouring masses of infantry and cavalry along the base of the mountain on our left, and was gaining our rear in great force. At this moment I arrived upon the field. The Mississippi regiment had been directed to the left before reaching the position, and immediately came into action against the Mexican infantry which had turned our flank. The 2d Kentucky regiment and a section of artillery under Captain Bragg, had previously been ordered from the right to reinforce our left, and arrived at a most opportune moment. That regiment, and a portion of the 1st Illinois, under Colonel Hardin, gallantly drove the enemy, and recovered portion of the ground we had lost. The batteries of Captains Sherman and Bragg were in position on the plateau, and did much execution, not only in front, but particularly upon the masses which had gained our rear. Discovering that the enemy was heavily pressing upon the Mississippi regiment, the 3d Indiana regiment, under a Battle of Buena Vista. Colonel Lane, was despatched to strengthen that part of our line, which formed a crotchet perpendicular to the first line of battle. At the same time Lieutenant Kilburn, with a piece of Captain Bragg's battery, was directed to support the infantry there engaged. The action was for a long time warmly sustained at that point-the enemy making several efforts both with infantry and cavalry against our line, and being always repulsed with heavy loss. I had placed all the regular cavalry and Captain Pike's squadron of Arkansas horse under the orders of Brevet Lieutenant-Colonel May, with directions to hold in check the enemy's column, still advancing to the rear along the base of the mountain, which was done in conjunction with the Kentucky and Arkansas cavalry under Colonels Marshall and Yell. In the mean time our left, which was still strongly threatened by a superior force, was farther strengthened by the detachment of Captain Bragg's and a portion of Captain Sherman's batteries to that quarter. The concentration of artillery fire upon the masses of the enemy along the base of the mountain, and the determined resistance offered by the two regiments opposed to them, had created confusion in their ranks, and some of the corps attempted to effect a retreat upon their main line of battle. The squadron of the 1st dragoons, under Lieutenant Rucker, was now ordered up the deep ravine which these retreating corps were endeavouring to cross, in order to charge and disperse them. The squadron proceeded to the point indicated, but could not accomplish the object, being exposed to a heavy fire from a battery established to cover the retreat of those corps. While the squadron was detached on this service, a Official report of General Taylor. large body of the enemy was observed to concentrate on our extreme left, apparently with the view of making a descent upon the hacienda of Buena Vista, where our train and baggage were deposited. Lieutenant-Colonel May was ordered to the support of that point, with two pieces of Captain Sherman's battery under Lieutenant Reynolds. In the mean time, the scattered forces near the hacienda, composed in part of Majors Trail and Gorman's commands, had been to some extent organized under the advice of Major Munroe, chief of artillery, with the assistance of Major Morrison, volunteer staff, and were posted to defend the position. Before our cavalry had reached the hacienda, that of the enemy had made its attack; having been handsomely met by the Kentucky and Arkansas cavalry under Colonels Marshall and Yell. The Mexican column immediately divided, one portion sweeping by the depot, where it received a destructive fire from the force which had collected there, and then gaining the mountain opposite, under a fire from Lieutenant Reynolds' section, the remaining portion regaining the base of the mountain on our left. In the charge at Buena Vista, Colonel Yell fell gallantly at the head of his regiment; we also lost Adjutant Vaughan, of the Kentucky cavalry—a young officer of much promise. Lieutenant-Colonel May, who had been rejoined by the squadron of the 1st dragoons and by portions of the Arkansas and Indiana troops, under Lieutenant-Colonel Roane and Major Gorman, now approached the base of the mountain, holding in check the right flank of the enemy, upon whose masses, crowded in the narrow gorges and ravines, our artillery was doing fearful execution. Battle of Buena Vista. The position of that portion of the Mexican army which had gained our rear was now very critical, and it seemed doubtful whether it could regain the main body. At this moment I received from General Santa Anna a message by a staff officer, desiring to know what I wanted. I immediately despatched Brigadier-General Wool to the Mexican general-in-chief, and sent orders to cease firing. Upon reaching the Mexican lines, General Wool could not cause the enemy to cease their fire, and accordingly returned without having an interview. The extreme right of the enemy continued its retreat along the base of the mountain, and finally, in spite of all our efforts, effected a junction with the remainder of the army. During the day, the cavalry of General Minon had ascended the elevated plain above Saltillo, and occupied the road from the city to the field of battle, where they intercepted several of our men. Approaching the town, they were fired upon by Captain Webster from the redoubt occupied by his company, and then moved off towards the eastern side of the valley, and obliquely towards Buena Vista. At this time, Captain Shover moved rapidly forward with his piece, supported by a miscellaneous command of mounted volunteers, and fired several shots at the cavalry with great effect. They were driven into the ravines which lead to the lower valley, closely pursued by Captain Shover, who was farther supported by a piece of Captain Webster's battery, under Lieutenant Donaldson, which had advanced from the redoubt, supported by Captain Wheeler's company of Illinois volunteers. The enemy made one or two efforts to charge the artillery, but was finally driven Official report of General Taylor. back in a confused mass, and did not again appear upon the plain. In the mean time, the firing had partially ceased upon the principal field. The enemy seemed to confine his efforts to the protection of his artillery, and I had left the plateau for a moment, when I was recalled thither by a very heavy musketry fire. On regaining that position, I discovered that our infantry (Illinois and 2d Kentucky) had engaged a greatly superior force of the enemy-evidently his reserve-and that they had been overwhelmed by numbers. The moment was most critical. Captain O'Brien, with two pieces, had sustained this heavy charge to the last, and was finally obliged to leave his guns on the field-his infantry support being entirely routed. Captain Bragg, who had just arrived from the left, was ordered at once into battery. Without any infantry to support him, and at the imminent risk of losing his guns, this officer came rapidly into action, the Mexican line being but a few yards from the muzzle of his pieces. The first discharge of canister caused the enemy to hesitate, and the second and third drove him back in disorder, and saved the day. The 2d Kentucky regiment, which had advanced beyond supporting distance in this affair, was driven back and closely pressed by the enemy's cavalry. Taking a ravine which led in the direction of Captain Washington's battery, their pursuers became exposed to his fire, which soon checked and drove them back with loss. In the mean time the rest of our artillery had taken position on the plateau, covered by the Mississippi and 3d Indiana regiments, the former of which had reached the ground in time to pour a fire into the |
