Major-General Zachary Taylor, at Agua Nueva, Mexico, to William L. Marcy, Secretary
of War, at Washington, D.C. Dispatch communicating Taylor's official report of the
Battle of Buena Vista.
Headquarters, Army of Occupation,
Agua Nueva, March 6th, 1847.
TO THE HON. SECRETARY OF WAR:
Sir: - I have the honor to submit a detailed report of the operations of the forces
under my command, which resulted in the engagement of Buena Vista, the repulse of the
Mexican army, and the reoccupation of this position.
The information which reached me of the advance and concentration of a heavy Mexican force in my front, had assumed such a probable form as to induce a special examination far beyond the reach of our pickets to ascertain its correctness. A small party of Texan spies, under Major McCullough, despatched to the hacienda of Encarnacion, thirty miles from this, on the route to San Luis Potosi, had reported a cavalry force of unknown strength at that place. On the 20th of February, a strong reconnoissance, under Lieutenant-colonel May, was despatched to the hacienda of Hecliondo, while Major McCullough made another examination of Encarnacion. The result of these expeditions left no doubt that the enemy was in large force at Encarnacion, under the orders of General Santa Anna, and that he meditated a forward movement and attack upon our position.
As the camp of Agua Nueva could be turned on either flank, and as the enemy's force was greatly superior to our own, particularly in the arm of cavalry, I determined, after much consideration, to take up a position about eleven miles in rear, and there await the attack. The army broke up its camp and marched at noon on the 21st, encamping at the new position a little in front of the hacienda of Buena Vista. With a small force I proceeded to Saltillo, to make some necessary arrangements for the defence of the town, leaving Brigadier-General Wool in the immediate command of the troops.
Before these arrangements were completed, on the morning of the 22d, I was advised that the enemy was sight, advancing. Upon reaching the ground it was found that his cavalry advance was in our front, having marched from Encarnacion, as we have since learned, at eleven o'clock the day previous, and driving in a mounted force left at Agua Nueva to cover the removal of public stores. Our troops were in position, occupying a line of remarkable strength. The road at this point becomes a narrow defile, the valley on its right being rendered quite impracticable for artillery by a succession of deep and impassable gullies, while on the left a succession of rugged ridges and precipitous ravines extends far back towards the mountain which bounds the valley. The features of the ground were such as nearly to paralyze the artillery and cavalry of the enemy, while his infantry could not derive all the advantage of its numerical superiority. In this position we prepared to receive him. Captain Washington's battery (Fourth artillery) was posted to command the road, while the First and Second Illinois regiments, under Colonels Hardin and Bissell, each eight companies, (to the latter of which was attached Captain Conner's company of Texas volunteers,) and the Second Kentucky, under Colonel McKee, occupied the crests of the ridges on the left and in rear. The Arkansas and Kentucky regiments of cavalry, commanded by Colonels Yell and H. Marshall, occupied the extreme left near the base of the mountain, while the Indiana brigade, under Brigadier-General Lane, (composed of the Second and Third regiments, under Colonels Bowles and Lane,) the Mississippi riflemen, under Colonel Davis, the squadrons of the First and Second dragoons, under Captain Steene and Lieutenant-colonel May, and the light batteries of Captains Sherman and Bragg, Third artillery, were held in reserve.
At eleven o'clock I received from General Santa Anna a summons to surrender at discretion, which, with a copy of my reply, I have already transmitted. The enemy still forbore his attack, evidently waiting for the arrival of his rear columns, which could be distinctly seen by our look-outs as they approached the field. A demonstration made on his left caused me to detach the Second Kentucky regiment and a section of artillery to our right, in which position they bivouacked for the night. In the mean time the Mexican light troops had engaged ours on the extreme left (composed of parts of the Kentucky and Arkansas cavalry dismounted, and a rifle battalion from the Indiana brigade under Major Gorman, the whole commanded by Colonel Marshall,) and kept up a sharp fire, climbing the mountain side, and apparently endeavoring to gain our flank. Three pieces of Captain Washington's battery had been detached to the left, and were supported by the Second Indiana regiment. An occasional shell was thrown by the enemy into this part of our line, but without effect. The skirmishing of the light troops was kept up with trifling loss on our part until dark, when I became convinced that no serious attack would be made before the morning, and returned, with the Mississippi regiment and squadron of Second dragoons, to Saltillo. The troops bivouacked without fires, and laid upon their arms. A body of cavalry, some fifteen hundred strong, had been visible all day in rear of the town, having entered the valley through a narrow pass, east of the city. This cavalry, commanded by General Minon, had evidently been thrown in our rear to break up and harass our retreat, and perhaps make some attempt against the town, if practicable. The city was occupied by four excellent companies of Illinois volunteers, under Major Warren, of the First regiment. A field-work, which commanded most of the approaches, was garrisoned by Captain Webster's company, First artillery, and armed with two twenty-four pound howitzers, while the train and head-quarter camp was guarded by two companies of Mississippi riflemen, under Captain Rogers, and a field-piece, commanded by Captain Shover, Third artillery. Having made these dispositions for the protection of the rear, I proceeded on the morning of the 23d to Buena Vista, ordering forward all the other available troops. The action had commenced before my arrival on the field.
During the evening and night of the 22d, the enemy had thrown a body of light troops on the mountain side, with the purpose of outflanking our left; and it was here that the action of the 23d commenced at an early hour. Our riflemen, under Colonel Marshall, who had been reinforced by three companies under Major Trail, Second Illinois volunteers, maintained their ground handsomely against a greatly superior force, holding themselves under cover, and using their weapons with deadly effect. About eight o'clock, a strong demonstration was made against the centre of our position, a heavy column moving along the road. This forces was soon dispersed by a few rapid and well-directed shots from Captain Washington's battery. In the mean time the enemy was concentrating a large force of infantry and cavalry under cover of the ridges, with the obvious intention of forcing our left, which was posted on an extensive plateau. The Second Indiana and Second Illinois regiments formed this part of our line, the former covering three pieces of light artillery, under the orders of Captain O'Brien - Brigadier-General Lane being in the immediate command. In order to bring his men within effective range, General Lane ordered the artillery and Second Indiana regiment forward. The artillery advanced within musket-range of it with great effect, but without being able to check its advance. The infantry ordered to its support had fallen back in disorder, being exposed, as well as the battery, not only to a severe fire of small-arms from the front, but also to a murderous cross-fire of grape and canister, from a Mexican battery on the left. Captain O'Brien found it impossible to retain his position without support, but was only able to withdraw tow of his pieces, all the horses and cannoneers of the third piece being killed or disabled. The Second Indiana regiment, which had fallen back as stated, could not be rallied, and took no farther part in the action, except a handful of men, who, under its gallant colonel, Bowles, joined the Mississippi regiment, and did good service, and those fugitives who, at a later period in the day, assisted in defending the train and depot at Buena Vista. 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 defence of which they afterwards contributed.
Col. Bissell's regiment, (Second 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 Second Kentucky regiment, and 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 First Illinois, under Colonel Hardin, gallantly drove the enemy, and recovered a 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 Third Indiana regiment, under Colonel Lane, was despatched to strengthen that part of our line which formed a crochet 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 place 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 First dragoons, under Lieutenant Rucker, was now ordered up the deep ravine which these retreating corps were endeavoring 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 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 Reynold's 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 First 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.
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 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 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 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 Second 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; the second and third drove him back in disorder and saved the day. The Second 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 Third Indiana regiments, the former of which had reached the ground in time to pour a fire into the right flank of the enemy, and thus contribute to his repulse.
In this last conflict we had the misfortune to sustain a very heavy loss. Colonel Hardin, First Illinois, and Colonel McKee and Lieutenant-colonel Clay, Second Kentucky regiment, fell at this time, while gallantly leading their commands.
No farther attempt was made by the enemy to force our position, and the approach of night gave an opportunity to pay proper attention to the wounded, and also to refresh the soldiers, who had been exhausted by incessant watchfulness and combat. Though the night was severely cold, the troops were compelled for the most to bivouac without fires, expecting that morning would renew the conflict. During the night the wounded were removed to Saltillo, and every preparation made to receive the enemy, should he again attack our position. Seven fresh companies were drawn from the town, and Brigadier-general Marshall, with a reinforcement of Kentucky cavalry and four heavy guns, under Captain Prentiss, First artillery, was near at hand, when it was discovered that the enemy had abandoned his position during the night. Our scouts soon ascertained that he had fallen back upon Agua Nueva. The great disparity of numbers, and the exhaustion of our troops, rendered it inexpedient and hazardous to attempt pursuit. A staff officer was despatched to General Santa Anna, to negotiate an exchange of prisoners, which was satisfactorily completed on the following day. Our own dead were collected and buried and the Mexican wounded, of which a large number had been left upon the field, were removed to Saltillo, and rendered as comfortable as circumstances would permit.
On the evening of the 26th, a close reconnoissance was made of the enemy's position, which was found to be occupied only by a small body of cavalry, the infantry and artillery having retreated in the direction of San Luis Potosi. On the 27th, our troops resumed their former camp at Agua Nueva, the enemy's rear-guard evacuating the place as we approached, leaving a considerable number of wounded. It was my purpose to beat up his quarters at Encarnacion early the next morning, but upon examination, the weak condition of the cavalry horses rendered it inadvisable to attempt so long a march without water. A command was finally despatched to Encarnacion, on the 1st of March, under Captain Belknap. Some two hundred wounded, and about sixty Mexican soldiers were found there, the army having passed on in the direction of Matehuala, with greatly reduced numbers, and suffering much from hunger. The dead and dying were strewed upon the road and crowded the buildings of the hacienda.
The American force engaged in the action of Buena Vista is shown, by the accompanying field report, to have been three hundred and thirty-four officers, and four thousand four hundred and twenty-five men, exclusive of the small command left in and near Saltillo. Of this number, two squadrons of cavalry and three batteries of light artillery, making not more than four hundred and fifty-three men, composed the only force of regular troops. The strength of the Mexican army is stated by General Santa Anna, in his summons, to be twenty thousand; and that estimate is confirmed by all the information since obtained. Our loss is two hundred and sixty-seven killed, four hundred and fifty-six wounded, and twenty-three missing. Of the numerous wounded, many did not require removal to the hospital, and it is hoped that a comparatively small number will be permanently disabled. The Mexican loss in killed and wounded may be fairly estimated at one thousand and five hundred, and will probably reach two thousand. At least five hundred of their killed were left upon the field of battle. We have no means of ascertaining the number of deserters and dispersed men from their ranks, but it is known to be very great.
Our loss has been especially severe in officers, twenty-eight having been killed upon the field. We have to lament the death of Captain George Lincoln, assistant adjutant-general, serving in the staff of General Wool - a young officer of high bearing and approved gallantry, who fell early in the action. No loss falls more heavily upon the army in the field than that of Colonels Hardin and McKee, and Lieutenant-colonel Clay. Possessing in a remarkable degree the confidence of their commands, and the last two having enjoyed the advantage of a military education, I had looked particularly to them for support in case we met the enemy. I need not say that their zeal in engaging the enemy, and the cool and steadfast courage with which they maintained their positions during the day, fully realized my hopes, and caused me to feel yet more sensibly their untimely loss.
I perform a grateful duty in bringing to the notice of the government the general good conduct of the troops. Exposed for successive nights, without fires, to the severity of the weather, they were very prompt and cheerful in the discharge of every duty; and finally displayed conspicuous steadiness and gallantry in repulsing, at great odds, a disciplined foe. While the brilliant success achieved by their arms releases me from the painful necessity of specifying many cases of bad conduct before the enemy, I feel an increased obligation to mention particular corps and officers, whose skill, coolness, and gallantry in trying situations, and under a continued and heavy fire, seem to merit particular notice.
To Brigadier-general Wool my obligations are especially due. The high state of discipline and instruction of several of the volunteer regiments was attained under his command, and to his vigilance and arduous service before the action, and his gallantry and activity on the field, a large share of our success may justly be attributed. During most of the engagement he was in immediate command of the troops thrown back on our left flank. I beg leave to recommend him to the favorable notice of the government. Brigadier-general Lane (slightly wounded) was active and zealous throughout the day, and displayed great coolness and gallantry before the enemy.
The services of the light artillery, always conspicuous, were more than usually distinguished. Moving rapidly over the roughest ground, it was always in action at the right place and the right time, and its well-directed fire dealt destruction in the masses of the enemy. While I recommend to particular favor the gallant conduct and valuable services of Major Munroe, chief of artillery, and Captains Washington, Fourth artillery, and Sherman and Bragg, Third artillery, commanding batteries, I deem it no more than just to mention all the subaltern officers. They were nearly all detached at different times, and in every situation exhibited conspicuous skill and gallantry. Captain O'Brien, Lieutenants Brent, Whiting, and Couch, Fourth artillery, and Bryan, topographical engineers, (slightly wounded,) were attached to Captain Washington's battery. Lieutenants Thomas, Reynolds, and French, Third artillery, (severely wounded,) to that of Captain Sherman; and Captain Shover and Lieutenant Donaldson, First artillery, rendered gallant and important service in repulsing the cavalry of General Minon. The regular cavalry, under Lieutenant-colonel May, with which was associated Captain Pike's squadron of Arkansas horse, rendered useful service in holding the enemy in check and in covering the batteries at several points. Captain Steene, First Dragoons, was severely wounded early in the day, while gallantly endeavoring, with my authority, to rally the troops which were falling to the rear.
The Mississippi riflemen, under Colonel Davis, were highly conspicuous for their gallantry and steadiness, and sustained throughout the engagement the reputation of veteran troops. Brought into action against an immensely superior force, they maintained themselves for a long time unsupported and with heavy loss, and held an important part of the field until reinforced. Colonel Davis, though severely wounded, remained in the saddle until the close of the action. His distinguished coolness and gallantry at the head of his regiment on this day, entitle him to the particular notice of the government. The Third Indiana regiment, under Colonel Lane, and a fragment of the Second, under Colonel Bowles, were associated with the Mississippi regiment during the greater portion of the day, and acquitted themselves creditably in repulsing the attempts of the enemy to break that portion of our line. The Kentucky cavalry, under Colonel Marshall, rendered good service dismounted, acting as light troops on our left, and afterwards, with a portion of the Arkansas regiment, in meeting and dispersing the column of cavalry at Buena Vista. The First and Second Illinois, and the Kentucky regiments, served immediately under my eye, and I bear a willing testimony to their excellent conduct throughout the day. The spirit and gallantry with which the First Illinois and Second Kentucky engaged the enemy in the morning, restored confidence to that part of the field, while the list of casualties will show how much these three regiments suffered in sustaining the heavy charge of the enemy in the afternoon. Captain Conner's company of Texas volunteers, attached to the Second Illinois regiment, fought bravely, its captain being wounded and two subalterns killed. Colonel Bissell, the only surviving colonel of these regiments, merits notice for his coolness and bravery on this occasion. After the fall of the field-officers of the First Illinois and Second Kentucky regiments, the command of the former devolved upon Lieutenant-colonel Weatherford; that of the latter upon Major Fry.
Regimental commanders and other who have rendered reports, speak in general terms of the good conduct of their officers and men, and specified many names, but the limits of this report forbid a recapitulation of them here. I may, however, mention Lieutenants Rucker and Campbell of the dragoons, and Captain Pike, Arkansas cavalry, commanding squadrons; Lieutenant-colonel Field, Kentucky cavalry; Lieutenant-colonel Roane, Arkansas cavalry, upon whom the command devolved after the fall of Colonel Yell; Major Bradford, Captain Sharpe, (severely wounded,) and Adjutant Griffith, Mississippi regiment; Lieutenant-colonel Hadden, Second Indiana regiment and Lieutenant Robinson, aid-de-camp to General Lane; Lieutenant-colonel Weatherford, First Illinois regiment; Lieutenant-colonel Morrison, Major Trail, and Adjutant Whiteside, (severely wounded,) Second Illinois regiment; and Major Fry, Second Kentucky regiment, as being favorably noticed for gallantry and good conduct. Major McCulloch, quartermaster in the volunteer service, rendered services before the engagement, in the command of a spy company, and during the affair was associated with the regular cavalry. To Major Warren, First Illinois volunteers, I feel much indebted for his firm and judicious course, while exercising command in the city of Saltillo.
The medical staff, under the able direction of Assistant-surgeon Hitchcock, were assiduous in attention to the wounded on the field, and in their careful removal to the rear. Both in these respects, and in the subsequent organization and service of the hospitals, the administration of this department was every thing that could be wished.
Brigadier-general Wool speaks in high terms of the officers of his staff, and I take pleasure in mentioning them here, having witnessed their activity and zeal upon the field. Lieutenant and Aid-de-camp McDowell, Colonel Churchill, inspector-general, Captain Chapman, assistant-quartermaster, Lieutenant Sitgreaves, topographical engineers, and Captains Howard and Davis, volunteer service, are conspicuously noticed by the General for their gallantry and good conduct. Messrs. March, Addicks, Potts, Harrison, Burgess, and Dusenbery, attached in various capacities to General Wool's headquarters, are likewise mentioned for their intelligent alacrity in conveying orders to all parts of the field.
In conclusion, I beg leave to speak of my own staff, to whose exertions in rallying troops and communicating orders I feel greatly indebted. Major Bliss, assistant-adjutant-general, Captain J. H. Eaton, and Lieutenant R. S. Garnett, aids-de-camp, served near my person, and were prompt and zealous in the discharge of every duty. Major Munroe, besides rendering valuable service as chief of artillery, was active and instrumental, as were also Colonels Churchill and Belknap, inspectors-general, in rallying troops and disposing them for the defence of the train and baggage. Colonel Whiting, quartermaster-general, and Captain Eaton, chief of the subsistence department, were engaged with the duties of their departments, and also served in my immediate staff on the field. Captain Sibley, assistant-quartermaster, was necessarily left with the headquarter camp near town, where his services were highly useful. Major Mansfield and Lieutenant Benham, engineers, and Captain Linnard and Lieutenants Pope and Franklin, topographical engineers, were employed before and during the engagement in making reconnoissances, and on the field were very active in bringing information and in conveying my orders to distant points. Lieutenant Kingsbury, in addition to his proper duties as ordnance officer, Captain Chilton, assistant-quartermaster, and Majors Dix and Coffee, served also as extra aids-de-camp, and were actively employed in the transmission of orders. Mr. Thomas L. Crittenden, of Kentucky, though not in service, volunteered as my aid-de-camp on this occasion, and served with credit in that capacity. Major Craig, chief of ordnance, and Surgeon Craig, medical director, had been detached on duty from headquarters, and did not reach the ground until the morning of the 24th - too late to participate in the action, but in time to render useful services in their respective departments of the staff.
I respectfully enclose the returns of the troops engaged, and of casualties incident to the battle.
I am, sir, very respectfully, your obedient servant,
Major General U.S.A. Comm'g.
