On December 15, 1862, Burnside's Union army withdrew from the Battle of Fredericksburg back to Falmouth, Virginia. It was a defeat for Burnside and a win for Lee. Lee suffered 5,300 casualties defending Fredericksburg. Union losses were more than twice as many. In total Burnside lost about 12,600 Union soldiers; killed, wounded, or missing. Morale in the Union army was very low that winter. There was political pressure from Washington to continue the “On to Richmond” offensive that had failed up that point in time. The Northern newspapers reported that 75,000 Confederate soldiers from Lee's army had been sent to reinforce the North Carolina coast. Burnside wanted to move against Lee while the Army of Northern Virginia was weakened. He personally scouted the area above Falmouth for the best place for his army to cross the Rappahannock. As late as January 15, he was still looking at places to cross. Confederate sharpshooters reported seeing Burnside near Banks ford and wondered what the General was up to. Finally, Burnside decided on Banks ford and U.S. ford. He sent troops to Muddy ford to draw attention away from his planned crossing points. On the morning of January 20 the army began to move.
