Burnside Takes Over
The new commander, a reluctant Ambrose Burnside, was immediately put under pressure to announce his plans by General in Chief Henry Halleck in afternoon telegram of the same day;
WAR DEPARTMENT, Washington City, November 5, 1862. Major-General BURNSIDE, Commanding, &c.:
GENERAL: Immediately on assuming command of the Army of the Potomac you will report the position of your troops and what you purpose doing with them.
Very respectfully, your obedient servant, H. W. HALLECK,
Burnside submitted a plan that was not radically changed from the course of operations envisioned by the departed McClellan. Once established near Falmouth, he proposed to strike out towards Richmond forcing Lee to rush to the defense of the capital. Stretched out in this manner Burnside believed Lee could be defeated piecemeal. Halleck was doubtful but nevertheless avoided the decision making process by submitting the plan to President Lincoln for approval. An equally dubious President Lincoln, anxious for some action, reluctantly agreed to the proposed course of action. Halleck relayed the approval to Burnside in a telegram on November 14, 1862.
Maj. Gen. AMBROSE E. BURNSIDE, Commanding Army of the Potomac:
The President has just assented to your plan. He thinks it will succeed if you move rapidly; otherwise not.
H. W HALLECK
Burnside wasted no time moving his forces. By November 17th his vanguard (Sumner's Grand Division) entered Falmouth. The Army of the Potomac had managed to sneak a march on the unsuspecting Confederates. Work on the new supply system was begun and everything seemed to be in motion for a successful campaign … except one thing! The very thing that was expected to improve their supply situation now presented the greatest obstacle to their plans. The move east had taken the army away from the narrow fordable portion of the river and situated it where bridges would be needed to pass over the river. The means to bridge the river was critical and did not go unnoticed by Burnside. The Engineer Battalion, then at Warrenton with the bulk of the army, began its move from Warrenton on November 17th. Moving separately as not to slow the other forces the regular engineers made Catlett's Station that night. The end of the second day of the march found them securing their campsite with pickets as they continued to find themselves alone in unfamiliar territory. By the 20th they had passed through Stafford Court House and were camped two miles from Falmouth. Abutment sills for a bridge was started on the 24th but was abandoned when the other bridging assets failed to appear as expected. After a Thanksgiving that was celebrated "as well as possible" the camp was then moved adjacent to the General Headquarters of the army.
The army still lacked the required bridging material to begin. Burnside was frustrated as he had expected to see the Engineer Brigade bridges waiting for him as he occupied Falmouth. Preliminary orders for the Engineer Brigade to move their bridging material from Berlin, Maryland (opposite Harper's Ferry) by water to Washington had been previously issued by McClellan.
The orders read in part:
The commanding general directs that you will take such steps as you deem advisable to accomplish the following objects: Detail a competent officer and one company from your command to take charge of the pontoon bridges at Harper's Ferry. Send such additional boats and material to Harper's Ferry as may be necessary to secure the maintenance of these bridges and provide for contingencies Send the balance of your bridge material to Washington.
Proceed to Washington with the balance of your command and make up a pontoon train on wheels as speedily as possible, with the necessary transportation, and be prepared to march with the train at a moment's notice. Have the bridge at Berlin dismantled and sent to Washington as soon as practicable.
The pontoon issue was again raised at a November 12th meeting between Burnside and Halleck at Warrenton. Burnside reported that;
"In my interview with General Halleck I represented to him that soon after commencing the movement in the direction of Fredericksburg my telegraphic communication with Washington would be broken, and that I relied upon him to see that such parts of my plan as required action in Washington would be carried out. He told me that everything required by me would receive his attention and that he would at once order, by telegraph, the pontoon trains spoken of in my plan and would, upon his return to Washington, see that they were promptly forwarded."
