Old map of Chancellorsville, Fredericksburg, Fredericksburg Region, United States, Virginia. Area depicted includes the Rappahannock River to the northeast, Taylor Hill to the northwest and Deep Run to the south. The Fredericksburg & Potomac Railroad is also indicated. As part of Gen. Hooker's plan to drive the Confederate Army back toward Richmond, Gen. Sedgwick was to undertake a diversionary attack across the Rappahannock River toward the Confederate entrenchments above Fredericksburg. On May 3rd, having started late and after meeting tougher opposition than anticipated, he did finally succeed in overrunning Marye's Heights and moved to reinforce Hooper's troops camped outside Chancellorsville in an area known as the Wilderness.
