American Civil War: The Appomattox campaign opened with the Battle of Lewis's Farm, in which the Confederate Army of Northern Virginia was forced into a series of retreats that would culminate in their surrender.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

The Appomattox campaign was a series of American Civil War battles fought March 29 – April 9, 1865, in Virginia that concluded with the surrender of Confederate General Robert E. Lee's Army of Northern Virginia to forces of the Union Army under the overall command of Lieutenant General Ulysses S. Grant, marking the effective end of the war.

The Battle of Lewis's Farm was fought on March 29, 1865, in Dinwiddie County, Virginia near the end of the American Civil War. In climactic battles at the end of the Richmond–Petersburg Campaign, usually referred to as the Siege of Petersburg, starting with Lewis's Farm, the Union Army commanded by Lieutenant General Ulysses S. Grant dislodged the Confederate Army of Northern Virginia commanded by General Robert E. Lee from defensive lines at Petersburg, Virginia and the Confederate capital of Richmond, Virginia. Many historians and the United States National Park Service consider the Battle of Lewis's Farm to be the opening battle of the Appomattox Campaign, which resulted in the surrender of Lee's army on April 9, 1865.

The Army of Northern Virginia was a field army of the Confederate States Army in the Eastern Theater of the American Civil War. It was also the primary command structure of the Department of Northern Virginia. It was most often arrayed against the Union's Army of the Potomac.
