Breakthrough At Petersburg (April 2)Further information: Third Battle of Petersburg
Back at the entrenchments around Petersburg, Grant ordered a general assault against the Petersburg lines by the II, VI Corps, IX, and XXIV Corps on April 2. A heroic defense of Fort Gregg by a handful of Confederates prevented the Federals from entering the city that night. Confederate Lt. Gen. A.P. Hill was killed trying to reach his troops in the confusion. After dark, Lee ordered the evacuation of Petersburg and Richmond.
