The silent city of military graves at Fredericksburg is a memorial of one of the bloodiest battles of the Civil War. The battle of Antietam had been regarded a victory by the Federals and a source of hope to the North, after a wearisome period of inaction and defeats. General George B. McClellan, in command of the Army of the Potomac, failed to follow up this advantage and strike fast and hard while the Southern army was shattered and weak. President Lincoln's impatience was brought to a climax; McClellan was relieved and succeeded by General Ambrose E. Burnside, who was looked upon with favor by the President, and who had twice declined this proffered honor. It was on November 5, 1862, nearly two months after Antietam, when this order was issued. The Army of the Potomac was in splendid form and had made plans for a vigorous campaign. On the 9th Burnside assumed command, and on the following day McClellan took leave of his beloved troops. Burnside at once changed the whole plan of campaign, and decided to move on Fredericksburg, which lay between the Union and Confederate armies. He organized his army into three grand divisions, under Generals Sumner, Hooker, and Franklin, commanding the right, center, and left, and moved his troops from Warrenton to Falmouth. A delay of some two weeks was due to the failure of arrival of the pontoons. In a council of war held on the night of December 10th the officers under Burnside expressed themselves almost unanimously as opposed to the plan of battle, but Burnside disregarded their views and determined to carry out his original plans immediately. After some delay and desultory fighting for two days, the crossing of the army was effected by the morning of December 13th. By this time General Robert E. Lee, commanding the Confederates, had his army concentrated and entrenched on the hills surrounding the town. In their efforts to place their bridges the Federals were seriously hindered by the firing of the Confederate sharpshooters--"hornets that were stinging the Army of the Potomac into a frenzy." The Confederate fire continued until silenced by a heavy bombardment of the city from the Federal guns, when the crossing of the army into Fredericksburg was completed without further interference.
