Union columns converged on Petersburg on April 2, pushing through a large section of the Confederate defensive entrenchments. As Robert E. Lee desperately sought to buy time to allow his army to withdraw, Ulysses S. Grant launched several other attacks. Stubborn Confederate resistance at Fort Gregg delayed Grant's progress. Meanwhile, Maj. Gen. Nelson A. Miles's Union division battered Henry Heth's Confederates near Sutherland's Station and drove them off the field. The Confederate defenders were scattered and driven northwestward. With this victory, the Federals possessed the South Side Railroad, Gen. Robert E. Lee's last supply line into Petersburg. However, the lengthy defense of Fort Gregg and Grant's hesitation in aggressively following up on his success at Sutherland's Station permitted Lee to evacuate his army that night.
