No. 78.-report of Brig. Gen. B. M. Prentiss, U. S. Army, commanding Sixth Division.
Quincy, Ill., November 17, 1862.Colonel: Upon my return from captivity in the hands of the public enemy I have the honor to submit my report of the part taken in the battle of the 6th of April last, near Pittsburg Landing, by the Sixth Division, Army of West Tennessee, the command of which had been assigned to me. I have the honor to transmit field return of the force which was subjected to my control, as it appeared upon the morning of the engagement, the same being marked A. t Saturday evening, pursuant to instructions received when I was assigned to duty with the Army of West Tennessee, the usual advance guard was posted, and in view of information received from the commandant thereof, I sent forward five companies of the Twenty-fifth Missouri and five companies of the Twenty-first Missouri Infantry, under command of Col. David Moore, Twenty-first Missouri. I also, after consultation with Col. David Stuart, commanding a brigade of General Sherman's division, sent to the left one company of the Eighteenth Wisconsin Infantry, under command of Captain Fisk. At about 7 o'clock the same evening Colonel Moore returned, reporting  some activity in the front — an evident reconnaissance by cavalry. This information received, Iproceeded to strengthen the guard stationed on the Corinth road, extending the picket lines to the front a distance of a mile and a half, at the same time extending and doubling the lines of the grand guard. At 3 o'clock on the morning of Sunday, April 6, Col. David Moore, Twenty-first Missouri, with five companies of his infantry regiment, proceeded to the front, and at break of day the advance pickets were driven in whereupon Colonel Moore pushed forward and engaged the enemy's advance, commanded by General Hardee. At this stage a messenger was sent to my headquarters, calling for the balance of the Twenty-first Missouri, which was promptly sent forward. This information received, I at once ordered the entire force into line, and the remaining regiments of the First Brigade, commanded by Col. Everett Peabody, consisting of the Twenty-fifth Missouri, Sixteenth Wisconsin, and Twelfth Michigan Infantry, were advanced well to the front. I forthwith at this juncture communicated the fact of the attack in force to Major-General Smith and Brig. Gen. S. A. Hurlbut. Shortly before 6 o'clock, Col. David Moore having been severely wounded, his regiment commenced falling back, reaching our front line at about 6 o'clock, the enemy being close upon his rear. Hereupon the entire force, excepting only the Sixteenth Iowa, which had been sent to the field the day previous without ammunition, and the cavalry, which was held in readiness to the rear, was advanced to the extreme front, and thrown out alternately to the right and left. Shortly after 6 o'clock the entire line was under fire, receiving the assault made by the entire force of the enemy, advancing in, three columns simultaneously upon our left, center, and right. This position was held until the enemy had passed our right flank, this movement being effected by reason of the falling back of some regiment to our right not belonging to the division. Perceiving the enemy was flanking me, I ordered the division to retire in line of battle to the color line of our encampment, at the same time communicating to Generals Smith and Hurlbut the fact of the falling back, and asking for re-enforcements. Being again assailed, in position described, by an overwhelming force, and not being able longer to hold the ground against the enemy, I ordered the division to fall back to the line occupied by General Hurlbut, and at 9.05 a. m. reformed to the right of General Hurlbut, and to the left of Brig. Gen. W. H. L. Wallace, who I found in command of the division assigned to Major-General Smith. At this point the Twentythird Missouri Infantry, commanded by Colonel Tindall, which had just disembarked from a transport, and had been ordered to report to me as a part of the Sixth Division, joined me. This regiment I immediately assigned to position on the left. My battery (Fifth Ohio) was posted to the right on the road. At about 10 o'clock my line was again assailed and finding my command greatly reduced by reason of casualties and because of the falling back of many of the men to the river, they being panic-stricken — a majority of them having now for the first time been exposed to fire — I communicated with General W. H. L. Wallace, who sent to my assistance the Eighth Iowa Infantry, commanded by Col. J. L. Geddes. After having once driven the enemy back from this position Maj. Gen. U. S. Grant appeared upon the field. I exhibited to him the disposition of my entire force, which disposition received his commendation, and I received my final orders, which were to maintain that position  at all hazards. This position I did maintain until 4 o'clock p. m., when Genei A1 Hurlbut, being overpowered, was forced to retire. I was then compelled to change front with the Twenty-third Missouri, Twentyfirst Missouri, Eighteenth Wisconsin, Eighteenth Missouri, and part of the Twelfth Michigan, occupying a portion of the ground vacated by General Hurlbut. I was in constant communication with Generals Hurlbut and Wallace during the day, and both of them were aware oi the importance of holding our position until night. When the gallant Hurlbut was forced to retire General Wallace and myself consulted, and agreed to hold our positions at all hazards, believing that we could thus save the army from destruction; we having been now informed for the first time that all others had fallen back to the vicinity of the river. A few minutes after General W. H. L. Wallace received the wound of which he shortly afterwards died. Upon the fall of General Wallace, his division, excepting the Eighth Iowa, Colonel Geddes, acting with me, and the Fourteenth Iowa, Colonel Shaw; Twelfth Iowa, Colonel Woods, and Fifty-eighth Illinois, Colonel Lynch, retired from the field. Perceiving that I was about to be surrounded, and having dispatched my aide, Lieut. Edwin Moore, for re-enforcements, I determined to assail the enemy, which had passed between me and the river, charging upon him with my entire force. I found him advancing in mass, completely encircling my command, and nothing was left but to harass him and retard his progress so long as might be possible. This I did until 5.30 p. m., when, finding that further resistance must result in the slaughter of every man in the command I had to yield the fight. The enemy succeeded in capturing myself and 2,200 rank and file, many of them being wounded. Col. Madison Miller, Eighteenth Missouri Infantry, was during the day in command of a brigade, and was among those taken prisoner. He acted during the day with distinguished courage, coolness, and ability. Upon Col. J. L. Geddes, Eighth Iowa, the same praise can be partly bestowed. He and his regiment stood unflinchingly up to the work the entire portion of the day during which he acted under my orders. Col. J. S. Alban and his lieutenant-colonel, Beall, of the Eighteenth Wisconsin, were, until they were wounded ever to the front, encouraging their command. Col. Jacob Fry, of the Sixty-first Illinois, with an undrilled regiment fresh in the service, kept his men well forward under every assault until the third line was formed, when he became detached, and fought under General Hurlbut. Colonel Shaw, of the Fourteenth Iowa, behaved with great coolness, disposed his men sharply at every command, and maintained his front unbroken through several fierce attacks. Colonel Tindall, Lieutenant-Colonel Morton, and Major McCullough, of the Twenty-third Missouri, are entitled to high meed of praise for gallant conduct. It is difficult to discriminate among so many gallant men as surrounded me when we were forced to yield to the overpowering strength of the enemy. Their bravery under the hottest fire is testified to by the devotion with which they stood forward against fearful odds to contend for the cause they were engaged in. To the officers and men who thus held to the last their undaunted front too much praise cannot be given. Captain McMichael, assistant adjutant-general, attached to the division commanded by General Wallace, joined me upon the field when his gallant leader fell. He is entitled to special mention for his conduct while so serving. Col. David Moore is entitled to special mention.  Capt. A. Hickenlooper, of the Fifth Ohio Battery, by his gallant conduct, commended himself to general praise. My staff consisted of but three officers. Brigade Surg. S. W. Everett was killed early in the engagement, gallantly cheering the Eighteenth Missouri Regiment to the contest. Lieut. Edwin Moore, aide-de-camp, during the entire battle, was by my side, unless when detached upon the dangerous service of his office. Capt. Henry Binmore, assistant adjutant-general, was with me, performing his duty to my great satisfaction, until, being exhausted,.I compelled hLm to leave the field. I have the honor to be, colonel, very respectfully, your obedient servant,
