The Siege of Petersburg, encompassing several battles and smaller actions, was fought between June 9, 1864 and March 25, 1865, around Petersburg, Virginia, between Confederate Gen. Robert E. Lee’s Army of Northern Virginia and Union Lt. Gen. Ulysses S. Grant’s Army of the Potomac in the American Civil War. The siege ended in a decisive Union victory and resulted in approximately 70,000 total casualties.
Today, only a small portion of the battlefield, mainly northeast of the city, has been preserved as Petersburg National Battlefield. It would be impossible to preserve all the extensive earthworks that ringed the city south of the Appomattox River, but many forts and landmarks have been turned into city parks. The battlefield has been divided into two fronts: Eastern and Western. The Eastern Front Driving Tour is four miles and the Western Front Driving Tour is 16 miles.
The Siege of Petersburg wasn’t technically a siege because the city wasn’t entirely surrounded, but it shared similar characteristics, including fortifications, mortar bombardments, and near-constant, low-intensity fighting. It lasted 9 months, 2 weeks, and 2 days. Over time, the battle lines crawled westward as Ulysses S. Grant tried to find a way to cut Lee’s main supply line to the west and south.
