The Overland Campaign, also known as Grant's Overland Campaign and the Wilderness Campaign, was a series of battles fought in Virginia during May and June 1864, in the American Civil War. Lt. Gen. Ulysses S. Grant, general-in-chief of all Union armies, directed the actions of the Army of the Potomac, commanded by Maj. Gen. George G. Meade, and other forces against Confederate Gen. Robert E. Lee's Army of Northern Virginia. Although Grant suffered severe losses during the campaign, it was a strategic Union victory. It inflicted proportionately higher losses on Lee's army and maneuvered it into a siege at Richmond and Petersburg, Virginia, in just over eight weeks.
Crossing the Rapidan River on May 4, 1864, Grant sought to defeat Lee's army by quickly placing his forces between Lee and Richmond and inviting an open battle. Lee surprised Grant by attacking the larger Union army aggressively in the Battle of the Wilderness, resulting in heavy casualties on both sides.
