Upon being asked what causes he assigned for the failure of his attack, General Burnside replied to the Committee on the Conduct of the War: "It was found impossible to get the men up to the works. The enemy's fire was too hot for them." [71]
After the battle of Fredericksburg the Army of Northern Virginia remained encamped on the south side of the Rappahannock until the latter part of April, 1863. The Federal army occupied the north side of the river opposite Fredericksburg, extending to the Potomac. Two brigades of Anderson's division—those of Mahone and Posey—were stationed near United States Mine or Bank Mill Ford. The cavalry was distributed on both flanks—Fitzhugh Lee's brigade picketing the Rappahannock above the mouth of the Rapidan and W. H. F. Lee's near Port Royal. General Longstreet, with two divisions of his corps, was detached for service south of James River in February, and did not rejoin the army until after the battle of Chancellorsville. Excepting a cavalry engagement near Kelly's Ford, on March 17th, nothing of interest transpired during this period of inactivity. On April 14, 1863, the enemy's cavalry was concentrating on the upper Rappahannock, but his efforts to establish himself on the south side of the river were successfully resisted. About the 21st, small bodies of infantry appeared at Kelly's Ford and the Rappahannock Bridge; at the same time a demonstration was made opposite Port Royal. These, movements indicated that the army, now commanded by Major-General Hooker, was about to resume active operations. On the 28th, early in the morning, the enemy crossed the river in boats near Fredericksburg, laid a pontoon-bridge, and built another about a mile below. A considerable force crossed on these bridges during the day, and was massed under the high banks of the river, which afforded protection from our artillery, while the batteries on the opposite heights completely commanded the wide plain between our lines and the narrow river. As in the first battle at Fredericksburg, our dispositions were made with a view to resist a direct advance against us. But the indications were that the principal effort would be made in some other quarter. On the 29th it was reported that he had crossed in force near Kelly's Ford, and that a heavy column was moving from Kelly's toward Germania Ford on the Rapidan, and another toward Ely's Ford. The routes they were pursuing, after crossing the Rapidan, converged near Chancellorsville, whence several roads led to the rear of our position at Fredericksburg. General Anderson proceeded to cover these roads on the 29th, but, learning that the enemy had crossed the Rapidan and was approaching in strong force, he retired early on the next morning to the intersection of the Mine and plank roads near Tabernacle Church, and began to intrench himself. His rear-guard, as he left Chancellorsville, was attacked by cavalry, but, being vigorously repulsed, offered no further opposition to his march.
The enemy on our front near Fredericksburg continued inactive, and it was now apparent that the main attack would be made upon our flank and rear. It was therefore determined to leave sufficient troops to hold our lines, and with the main body of the army to give battle to the approaching column. Early's division of Jackson's corps and Barksdale's brigade of McLaws's division, with part of the reserve artillery under General Pendleton, were intrusted with the defense of our position at Fredericksburg, and at midnight on the 30th General McLaws marched with the rest of his command toward Chancellorsville. General Jackson followed at dawn next morning with the remaining divisions of his corps. He reached the position occupied by General Anderson at 8 A.M., and immediately began to make preparations to advance. At 11 A.M. the troops moved forward on the plank and old turnpike roads. The enemy was soon encountered on both roads, and heavy skirmishing with infantry and artillery ensued, our troops pressing steadily forward. A strong attack upon McLaws was repulsed with spirit by Semmes's brigade; and General Wright, by direction of General Anderson, diverging to the left of the plank-road, marched by way of the unfinished railroad from Fredericksburg to Gordonsville and turned the Federal right. His whole line thereupon retreated rapidly, vigorously pursued by our troops until they arrived within about one mile of Chancellorsville. Here the enemy had assumed a position of great natural strength, surrounded on all sides by a dense forest filled with a tangled undergrowth, in the midst of which breastworks of logs had been constructed with trees felled in front so as to form an almost impenetrable abatis. His artillery swept the few narrow roads by which his position could be approached from the front, and commanded the adjacent woods. The left of his line extended from Chancellorsville toward the Rappahannock, covering the Bank Mill Ford, where he communicated with the north bank of the river by a pontoon-bridge. His right stretched westward along the Germania Ford road more than two miles. Darkness was approaching before the strength and extent of his line could be ascertained; and, as the nature of the country rendered it hazardous to attack by night, our troops were halted and formed in line of battle in front of Chancellorsville at right angles to the plank-road, extending on the right to the Mine road, and to the left in the direction of the "Furnace."
It was evident that a direct attack by us would be attended with great difficulty and loss, in view of the strength of his position and his superiority of numbers. It was therefore resolved to endeavor to turn his right flank and gain his rear, leaving a force in front to hold him in check and conceal the movement. The execution of this plan was intrusted to Lieutenant-General Jackson with his three divisions. The commands of Generals McLaws and Anderson, with the exception of Wilcox's brigade which during the night had been ordered hack to Banks's Ford, remained in front of the enemy. Early on the morning of the 2d General Jackson marched by the Furnace and Brock roads, his movement being effectually covered by Fitzhugh Lee's cavalry under General Stuart in person. As the rear of his train was passing the furnace a large force of the enemy advanced from Chancellorsville and attempted its capture, but this advance was arrested. After a long and fatiguing march General Jackson's leading division under General Rodes reached the old turnpike about three miles in rear of Chancellorsville at 4 P.M. As the different divisions arrived, they were formed at right angles to the road— Rodes's in front, Trimble's, under Brigadier-General Colston, in the second, and A. P, Hill's in the third line. At 6 P.M. the advance was ordered. The enemy was taken by surprise, and fled after a brief resistance. General Rodes's men pushed forward with great vigor and enthusiasm, followed closely by the second and third lines. Position after position was carried, the guns captured, and every effort of the foe to rally defeated by the impetuous rush of our troops. In the ardor of pursuit through the thick and tangled woods, the first and second lines at last became mingled and moved on together as one. The fugitives made a stand at a line of breastworks across the road, but the troops of Rodes and Colston dashed over the intrenchments together, and the flight and pursuit were resumed and continued until our advance was arrested by the abatis in front of the line of works near the central position at Chancellorsville. It was now dark, and General Jackson ordered the third line under General Hill to advance to the front and relieve the troops of Rodes and Colston, who were completely blended and in such disorder from their advance through intricate woods and over broken ground that it was necessary to reform them. As Hill's men moved forward, General Jackson, with his staff and escort, returning from the extreme front, met the skirmishers advancing, and in the obscurity of the night were mistaken for the enemy and fired upon. Captain Boswell, chief engineer of the corps, and several others, were killed and a number wounded, among whom was General Jackson, who was borne from the field. The command devolved upon Major-General Hill, whose division under General Heath was advanced to the line of intrenchments which had been reached by Rodes and Colston. A furious fire of artillery was opened upon them, under cover of which infantry advanced to the attack, but were handsomely repulsed. General Hill was soon afterward disabled, and the command was turned over to General Stuart. He immediately proceeded to reconnoiter the ground and make himself acquainted with the disposition of the troops. The darkness of the night and the difficulty of moving through the woods and undergrowth rendered it advisable to defer further operations until morning, and the troops rested on their arms in line of battle.
As soon as the sound of cannon gave notice of Jackson's attack on the enemy's right, the troops in front began to press strongly on the left to prevent reënforcements being sent to the point assailed. They advanced up to the intrenchments, while several batteries played with good effect until prevented by the increasing darkness.
Early on the morning of May 3d General Stuart renewed the attack upon General Hooker, who had strengthened his right wing during the night with additional breastworks, while a large number of guns, protected by intrenchments, were posted so as to sweep the woods through which our troops had to advance. Hill's division was in front, with Colston in the second line, and Rodes in the third. The second and third lines soon advanced to the support of the first, and the whole became hotly engaged. The breastworks at which the attack was suspended on the preceding evening were carried by assault, under a terrible fire of musketry and artillery. In rear of these breastworks was a barricade, from which the enemy was quickly driven. The troops on the left of the plank-road, pressing through the woods, attacked and broke the next line, while those on the right bravely assailed the extensive earthworks behind which General Hooker's artillery was posted. Three times were these works carried, and as often were the brave assailants compelled to abandon them—twice by the retirement of the troops on their left, who fell back after a gallant struggle with superior numbers, and once by a movement of the enemy on their right caused by the advance of General Anderson. The left, being reënforced, finally succeeded in driving back the enemy, and the artillery under Lieutenant-Colonels Carter and Jones, being thrown forward to occupy favorable positions secured by the advance of the infantry, began to play with great precision and effect. Anderson, in the mean time, pressed gallantly forward directly upon Chancellorsville, his right resting upon the plank-road and his left extending around the furnace, while McLaws made a strong demonstration to the right of the road. As the troops advancing upon the enemy's front and right converged upon his central position, Anderson effected a junction with Jackson's corps, and the whole line pressed irresistibly. General Hooker's army was driven from all its fortified positions with heavy loss in killed, wounded, and prisoners, and retreated toward the Rappahannock. By 10 A.M. we were in full possession of the field. The troops, having become somewhat scattered by the difficulties of the ground and the ardor of the contest, were immediately reformed, preparatory to renewing the attack. The enemy had withdrawn to a strong position nearer to the Rappahannock, which he had fortified. His superiority of numbers, the unfavorable nature of the ground, which was densely wooded, and the condition of our troops, after the arduous and sanguinary conflict in which they had been engaged, rendered great caution necessary. Our operations were just completed, when further movements were arrested by intelligence received from Fredericksburg.
Before dawn, on the morning of the 3d, it was known that the enemy had occupied Fredericksburg in large force, and laid down a bridge at the town. He made a demonstration against the extreme right of the force left to hold our lines, which was easily repulsed by General Early. Soon afterward a column moved from Fredericksburg along the river-banks, as if to gain the heights on the extreme left which commanded those immediately in rear of the town. This attempt was foiled. Very soon the enemy advanced in large force against Marye's, and the hills to the right and left of it. Two assaults were gallantly repulsed. After the second, a flag of truce was sent from the town to obtain permission to provide for the wounded. Three heavy lines advanced immediately upon the return of the flag and renewed the attack. They were bravely repulsed on the right and left, but the small force at the foot of Marye's Hill, overpowered by more than ten times their numbers, was captured after an heroic resistance and the hill carried. The success of the enemy enabled him to threaten our communications by moving down the Telegraph road, or to come upon our rear at Chancellorsville by the plank-road. He began to advance on the plank-road, his progress being gallantly disputed by the brigade of General Wilcox, who fell back slowly until he reached Salem Church on the plank-road, about five miles from Fredericksburg.
In this state of affairs in our rear, General Lee led General McLaws with his three brigades to reënforce General Wilcox. He arrived at Salem Church early in the afternoon, where he found General Wilcox in line of battle, with a large force of the enemy—consisting, as was reported, of one army corps and part of another—in his front. The enemy's artillery played vigorously upon our position for some time, when his infantry advanced in three strong lines, the attack being directed mainly against General Wilcox, but partially involving the brigades on his left. The assault was met with the utmost firmness, and after a fierce struggle the first line was repulsed with great slaughter. The second then came forward, but immediately broke under the close and deadly fire which it encountered, and the whole mass fled in confusion to the rear. They were pursued by the brigades of Wilcox and Semmes, which advanced nearly a mile, when they were halted to reform in the presence of the hostile reserve, which now appeared in large force. It being quite dark, General Wilcox deemed it imprudent to push the attack with his small numbers, and retired to his original position, the enemy making no attempt to follow. The next morning General Early advanced along the Telegraph road, and recaptured Marye's and the adjacent hills without difficulty, thus gaining the rear of the enemy's left. In the mean time General Hooker had so strengthened his position near Chancellorsville, that it was deemed inexpedient to assail it with less than our whole force, which had been reduced by the detachment led to Fredericksburg to relieve us from the danger that menaced our rear.
It has been heretofore stated that General Longstreet had been sent with two divisions of Lee's array to coöperate with General French on the south side of the James River, in the capture of Suffolk, the occupation of which by the enemy interrupted our collection of supplies in the eastern counties of North Carolina and Virginia. When the advance of Hooker threatened General Lee's front, instructions were sent to General Longstreet to hasten his return to the army with the large force detached with him. These instructions were repeated with urgent insistence, yet his movements were so delayed that, though the battle of Chancellorsville did not occur until many days after he was expected to join, his force was absent when it occurred. Had he rejoined his command in due time, Lee need not have diminished his force in front of Hooker, so as to delay the renewal of the attack and force him to a precipitate retreat, involving the loss of his artillery and trains. It was accordingly resolved still further to reënforce the troops in front, in order, if possible, to drive Hooker across the Rappahannock. Some delay occurred in getting the troops into position, owing to the broken and irregular nature of the ground, and the difficulty of ascertaining the disposition of the opposing forces. The attack did not begin until 6 P.M., when the enemy's troops were rapidly driven across the plank-road in the direction of the Rappahannock. The speedy approach of darkness prevented General McLaws from perceiving the success of the attack, until the foe began to recross the river a short distance below Banks's Ford, where he had laid one of his pontoon-bridges. His right brigades advanced through the woods in the direction of the firing, but the retreat was so rapid that they could only join in the pursuit. A dense fog settled over the field, increasing the obscurity and rendering great caution necessary to avoid collision between our own troops. Their movements were consequently slow. The next morning it was found that the enemy had made good his escape and removed his bridges. Fredericksburg was evacuated, and our rear no longer threatened. But, as General Hooker had it in his power to recross, it was deemed best to leave a force to hold our lines as before. McLaws and Anderson being directed to return to Chancellorsville, they reached their destination during the afternoon, in the midst of a violent storm, which continued throughout the night and most of the following day. Preparations were made to assail the enemy's works at daylight on the 6th, but, on advancing our skirmishers, it was found that, under cover of the storm and darkness of the night, he had retreated over the river. A detachment was left to guard the battle-field, while the wounded were removed and the captured property collected. The rest of the army returned to its former position.
The loss of the enemy, according to his own statement, was 1,512 killed and 9,518 wounded; total, 11,030. His dead and a large number of wounded were left on the field. About 5,000 prisoners, exclusive of the wounded, were taken, and 13 pieces of artillery, 19,500 stand of arms, 17 colors, and a large quantity of ammunition fell into our hands.
