Petersburg National Battlefield, which honors the U.S. Colored Troops who fought in the Civil War, is the site of Gen. Robert E. Lee's surrender.
Petersburg, Virginia, became the setting for the longest siege in American history when General Ulysses S. Grant failed to capture Richmond in the spring of 1864. Grant settled in to subdue the Confederacy by surrounding Petersburg and cutting off General Robert E. Lee's supply lines into Petersburg and Richmond.
On April 2, 1865, 292 days after the siege began, Lee evacuated Petersburg.
