During the night of the 10th of December, therefore, the pontoons were conveyed to the river, and the artillery to the number of one hundred and forty-three pieces was placed in position opposite the city. Between four and five o’clock on the morning of the 11th, the work of building four bridges was commenced. One was to be made at the point where the railroad bridge formerly crossed, and two others opposite the city but nearer Falmouth, and the fourth nearly two miles below for the crossing of the left wing under General Franklin. A dull haze so obscured the movement, that it was not discovered for some time by the Confederate pickets. The bridges were thus partly constructed, when a brisk and deadly fire of musketry from along the banks of the river and windows of the houses was opened, which compelled the workmen to stop. They fled to the cover of the surrounding hills where they formed again, and about six o’clock the work was recommenced. The Confederates had now become aroused to a sense of what was going forward, and with reinforcements of sharpshooters swarmed the opposite bank and houses. The pontonniers, nothing daunted by the hot fire poured upon them, went bravely to work. A storm of bullets covered them. The planks and boats were riddled by every volley. Once more they were compelled to withdraw, and again fell back to the cover of the ridge of hills running parallel with the river. Orders were now given to the artillery to open fire on the city. The Federal batteries commenced an almost simultaneous bombardment, directing their fire chiefly at the houses in which the sharpshooters had concealed themselves. At the first fire they became untenable, and the riflemen retreated to the rear of the town, and took shelter behind the buildings unharmed. The fire of the artillery, which commenced at seven o’clock, was continued incessantly until one o’clock. The fog somewhat obscured its results, but bodies of the Confederates with great stubbornness still kept within the city. The Confederate batteries on the heights in the rear continued silent. Not a gun was fired. About ten o’clock, the workmen were again formed for a third attempt to build the bridges. Volunteers joined them from the Eighth Connecticut. Some planks were seized and carried out to the end of a string of boats and placed in position, when a galling fire from sharpshooters in rifle pits near the edge of the water again interrupted them, and they were recalled. Meantime the bombardment was continued, and several houses in the city had taken fire. In the afternoon, several pontoon boats, loaded with volunteers from the Seventh Michigan and Nineteenth Massachusetts, were sent over. They chased the Confederate sharpshooters from their hiding places, and the bridges were finished without further interruption. On the other side a scene of destruction presented itself. The walls of houses were breached, roofs had fallen in, and the interiors were destroyed.
No sooner were the bridges completed than the troops began to cross, and before dusk General Sumner’s grand division had gone over, and a section of General Hooker’s. All had rations for three days, and blankets for a bivouac. The grand division of General Franklin, consisting of the corps of General Reynolds and Smith, crossed over at the lower bridge, which was built earlier in the day, without interruption, as there was a plain before it which the artillery could have easily swept. The troops commenced crossing again early on the morning of the 12th without molestation. Some sharp resistance had been made by the Confederate soldiers to those who crossed on the previous day, but those were driven out of the city, or killed. During the afternoon fire was opened upon the city by the Confederate batteries on the nearest heights, which was replied to by the Federal batteries, and soon ceased. The occupation of Fredericksburg had now been successfully made. No greater opposition had been presented by the forces of General Lee than was sufficient to tempt the Federal troops to press forward with greater ardor.
The next movement was to drive the Confederate forces from their positions on the heights. These positions consisted of two lines of batteries, one a mile in rear of the other, and both overlooking the city. They extended, in the form of a semicircle, from Port Royal to a point about six miles above Fredericksburg. Their right wing, under General Jackson, extended from Port Royal to Guinney’s Station on the Richmond and Fredericksburg railroad; the centre, under General Longstreet, extended to the telegraph road; the left, under General Stuart, was west of Massaponax creek. A reserve corps was commanded by General A. P. Hill. This was the force which had fought at Richmond and in Maryland.
Friday night and Saturday morning, the 13th, were spent by General Burnside in making a proper disposition of his forces. The left was occupied by General Franklin with his grand division, the centre by General Hooker, and the right by General Sumner.
The right of General Franklin rested on the outskirts of the city, his centre was advanced about a mile from the river, and his left was on the Rappahannock, about three miles below. The action commenced on the extreme left by an annoying fire from a rebel battery, which the Ninth New York was ordered to charge and capture. In this attempt they were repulsed. A brigade was brought to their aid by General Tyler, and another attempt made, but the fire was so deadly that it failed of success. The battle now became more general, and another attempt was made to capture the battery. No advantage was gained at this time, but a severe loss was suffered. The conflict now extended along the whole line of the left, and a desperate effort was made to drive the Confederates across the Massaponax creek by turning their position. The ground was contested most obstinately, but the Confederates gradually fell back, occasionally making a most desperate stand, until night, when General Franklin had succeeded in gaining nearly a mile, and his troops occupied the field. The right of General Franklin’s division, under General Reynolds, encountered the fire of the Confederate artillery on the heights, and although the conflict was most deadly, no advantage was gained.
On the right, under command of General Sumner, the action commenced about ten o’clock and was furious during the rest of the day. The Confederate forces occupied the woods and hills in the rear of the city, from which it soon became evident they could not be driven except at the point of the bayonet. The charge was ordered to be made by the division of General French supported by that of General Howard. Steadily the troops moved across the plain, until they were within a dozen yards of the ridge, when they were suddenly met by a galling fire from the Confederate infantry posted behind a stone wall. For a few minutes the head of the column exhibited some confusion; but quickly forming into line it retired back to a ravine within musket shot of the rebels. Here they were reinforced by fresh troops who fearlessly advanced to their aid under a most destructive fire of artillery. The line of assault was now formed again, and with bayonets fixed and a double quick step, they rushed forward to seize the Confederate artillery. From the first step they encountered a terrific fire of infantry and artillery. No veterans could face that shock. They were thrown into confusion and brought to a sudden halt. At this juncture the centre quivered, faltered, and fled in disorder, but was afterwards rallied and brought back. Three times was the attack thus made to dislodge those batteries. But each time it was in vain. The ranks of the storming party, shrunk to small limits, retired. The entire force of his artillery was now brought by General Sumner to bear upon the enemy, and thus the contest was kept up until dark. At night the Confederate force occupied their original position, and the wounded and the dead remained where they had fallen. Every attempt to remove them by the Federal troops was defeated by the rebel infantry.
In the centre under the command of General Hooker, skirmishing commenced early in the morning; and during the forenoon, while the fog prevailed, a terrific contest, chiefly with artillery, was kept up on both sides. The Confederate position appeared to be invulnerable to artillery, and about noon preparations were made for storming it. The troops marched steadily up within musket shot of the batteries, and were there met by such a destructive fire of artillery and rifles as drove them back with a heavy loss. Reinforcements were obtained, and the attempt to take the batteries was repeated in the afternoon, but without success. The contest continued with great fierceness until night. About half past five the firing of the musketry ceased, but that of the artillery continued until long after dark.
On the next day, Sunday the 14th, both armies remained comparatively quiet. Some skirmishing and artillery fire took place for a short time.
On Monday, both armies continued in the same position. The Confederates had strengthened some of their works. During the ensuing night, the army evacuated Fredericksburg and retired across the river to its former position. The artillery crossed first, followed by the infantry, the last of whom left about daylight. The pontoon bridges were then removed and all communication cut off. The movement was not perceived by the Confederates until it was too late to do any injury to the retreating force. The following is the despatch of General Burnside announcing this movement:
