During the battle of Fredericksburg, December 11-15, 1862, Major General Ambrose E. Burnside ordered brigade after brigade to attack across open ground against General Robert E. Lee’s Confederates, who were protected behind strong defenses on Marye’s Heights. The Federals suffered more than 12,000 casualties in the battle and retreated back across the Rappahannock River.
The Conservation Fund purchased a key property on Marye’s Heights, made possible by the Battlefield Revolving Fund established by grants from The Gilder Foundation, and held it until the National Park Service had the funding to purchase it and add it to the park. Nearby on the battlefield, the Fund used the Revolving Fund again to purchase twelve acres, which include Confederate earthworks constructed by General Pickett's soldiers in the 1862 battle, and held them for NPS purchase and addition to the park.
