Petersburg Breakthrough Battlefield

The Petersburg Breakthrough Battlefield is a historic district in Dinwiddie County, near Petersburg, Virginia. It was the location of the Third Battle of Petersburg, in which the Union Army broke through Confederate Army lines protecting Petersburg and Richmond on April 2, 1865, during the American Civil War. The success of the breakthrough led to abandonment of Richmond by General Robert E. Lee, a general retreat, and surrender at Appomattox Court House one week later. Portions of the area were listed on the National Register of Historic Places in 2003, and a different portion (overlapping the first) was designated a National Historic Landmark in 2006. Much of the battlefield area is part of Pamplin Historical Park, a private park that interprets the battle.

Description
The Petersburg Breakthrough Battlefield is located just southwest of Petersburg. It is a large area, roughly bounded on the northwest by United States Route 1, to the north by the Rohoic Woods Apartment complex on Virginia State Route 670, the east by Hofheimer Way and Church Road (Virginia State Route 672), and on the south by Arthur Swamp, an area that drains south into the Nottoway River. The battlefield area is located on private land just west of the Fort Fisher and Fort Welch area of Petersburg National Battlefield, a U.S. National Park Service-administered area. Much of this area is part of Pamplin Historical Park, a private park which interprets the battle.

The preserved portions of the battlefield include nearly 1700 ft of Confederate earthworks, which are among the best-preserved known. Archaeological evidence of the Confederate camps, located at the back of those works, is also present, as are a series of rifle pits dug by the Confederates. Some of these were taken over by Union forces in the action. Also included in the defenses are two dams (of an unknown number that would have been built) for the diversion of water in and around the defenses. On the east side of Arthur Swamp the Confederates built a large redan on one of the area's natural high points.

The battlefield area also now includes recreations of Confederate log cabins, built as part of their winter quarters, and the facilities of Pamplin Historical Park. The park area includes the Hart House, built 1859-61, which has been restored to its appearance of that time, and the c. 1812 Tudor Hall, a Federal period house that stood just outside the area where the battle took place.

The battlefield is the subject of two separate, overlapping designations. In 2003 "Petersburg Breakthrough Battlefield Historic District at Pamplin Historical Park" was listed on the National Register of Historic Places, encompasses about 422 acre, including all of Pamplin Historical Park and three adjacent residential properties. In 2006 an area of just over 647 acre was designated a National Historic Landmark. The latter designation includes larger areas of properties adjacent to Pamplin Park, and excludes portions of the park (such as Tudor Hall) that did not directly bear on the battle.
