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.
