Towards the latter part of the month General Jackson was called down and assigned position on the right near Hamilton's Crossing and the Massaponax. He objected to the position, preferring the North Anna, but General Lee had already weighed the matter, and had decided in favor of Fredericksburg. Hood's division, relieved at Hamilton's Crossing, was drawn to my right and stretched across the valley of Deep Run, a little to the rear of Jackson's left and McLaws's right.
Batteries of position were assigned from the reserve artillery along the heights, with orders to cover the guns, by epaulements or pitting them. The work was progressing while the guns were held under cover remote from the enemy's better appointed artillery until the positions were covered by solid banks or good pits. The small field pieces were removed for safety to convenient points for field service in case opportunity called for them. The Confederates had three hundred and six guns, including two thirty-pound Parrotts of Richmond make. These were covered by epaulements on Lee's Hill.
On the 1st of December the batteries of reserve artillery were relieved from the First Corps by those of the Washington and Alexander's artillery. Orders were given to examine all lines of approach, and to measure particularly the distance of the crossings of the canal on the Plank and Telegraph roads; to inspect and improve the parapets and pits along the front, and to traverse all batteries not securely covered against the batteries opposite Taylor's Hill, and others within range of our lines, and McLaws was directed to open signal line with his brigade and guards along the river bank.
The day after Jackson joined us several gun-boats were reported in the lower river at Port Royal. D. H. Hill's division was detached with several select batteries to watch and guard at that point against a crossing, should it be attempted, and to engage and try the metal of the gun-boats. After some little practice the boats drew off and dropped down-stream; but Hill's division was left near the point in observation with W. H. F. Lee's cavalry. The brigade of cavalry under General Hampton kept careful watch of the fords of the upper Rappahannock. To guard against further encroachments of the gun-boats, a battery was intrenched on the river bank under direction of Major T. M. R. Talcot, of the general staff. At the river, sharp-shooters, by concealing themselves in the ravines and pits, could escape artillery fire and lie in secure readiness to attack parties engaged in laying bridges. After driving off working parties they were to seek cover till again needed. By such practice they were to delay the bridge-builders till the commands had time to assemble at their points of rendezvous. The narrow, deep bed of the stream, a mile away from any point of the Confederate lines where batteries could be planted, and covered as it was by the guns of Stafford Heights, prevented the thought of successful resistance to laying bridges at any point from Falmouth to the extreme left of the Federal line; but the strong ground upon which the Confederates were to accept battle offset the uncomfortable feeling in regard to the crossing of the river.
