The Wilderness of Spotsylvania was a tightly forested area nearly twelve miles wide by six miles long; it was located south of the Rappahannock and Rapidan rivers, ten miles west of Fredericksburg, in Spotsylvania County, Virginia. During the(1861–1865), two major battles were fought there: , in May 1863, where Confederate general famously outflanked Union forces under ; and the , in May 1864, where the Union’s new general-in-chief, , initiated the Overland Campaign. The topography of the Wilderness—dense woods and thick undergrowth broken up by a number of small clearings—made the maneuvering of large armies particularly difficult and the experience of fighting claustrophobic. In both battles, burst shells ignited the woods, burning wounded soldiers. At Chancellorsville, Jackson was killed by a volley from his own men and, a year later, Confederate general was wounded, also by friendly fire.
