At approximately 7:00 a.m. on Sunday, April 2, 1865, Ulysses S. Grant’s army broke through Confederate lines and Lee decided to retreat. Lee sent a telegram to the Secretary of War: “I advise that all preparation be made for leaving Richmond tonight.”

Thus, the Petersburg Campaign, the longest of the Civil War, came to an end. The casualties for the entire period of the siege are estimated to be 42,000 for the Union, and 28,000 for the Confederates.
