context_page_description: The Richmond–Petersburg campaign was a series of battles around Petersburg, Virginia, fought from June 15, 1864, to April 2, 1865, during the American Civil War. Although it is more popularly known as the siege of Petersburg, it was not a classic military siege, in which a city is usually surrounded and all supply lines are cut off, nor was it strictly limited to actions against Petersburg. The campaign consisted of nine months of trench warfare in which Union forces commanded by Lt. Gen. Ulysses S. Grant assaulted Petersburg unsuccessfully and then constructed trench lines that eventually extended over 30 miles from the eastern outskirts of Richmond, Virginia, to around the eastern and southern outskirts of Petersburg. Petersburg was crucial to the supply of Confederate Gen. Robert E. Lee's army and the Confederate capital of Richmond. Numerous raids were conducted and battles fought in attempts to cut off the Richmond and Petersburg Railroad. Many of these battles caused the lengthening of the trench lines.
  Lee finally gave in to the pressure and abandoned both cities in April 1865, leading to his retreat and surrender at Appomattox Court House.
context_section_description: While Lee and Grant faced each other after Cold Harbor, Benjamin Butler became aware that Confederate troops had been moving north to reinforce Lee, leaving the defenses of Petersburg in a vulnerable state. Sensitive to his failure in the Bermuda Hundred Campaign, Butler sought to achieve a success to vindicate his generalship. He wrote, "the capture of Petersburg lay near my heart."
  Petersburg was protected by multiple lines of fortifications, the outermost of which was known as the Dimmock Line, a line of earthworks and trenches 10 miles (16 km) long, with 55 redoubts, east of the city. The 2,500 Confederates stretched thin along this defensive line were commanded by a former Virginia governor, Brig. Gen. Henry A. Wise. Despite the number of fortifications, because of a series of hills and valleys around the outskirts of Petersburg there were several places along the outer defenses where cavalry could easily ride through undetected until they reached the inner defenses of the city.
  Butler's plan was formulated on the afternoon of June 8, calling for three columns to cross the Appomattox and advance with 4,500 men. The first and second consisted of infantry from Maj. Gen. Quincy A. Gillmore's X Corps and U.S. Colored Troops from Brig. Gen. Edward W. Hinks's 3rd Division of XVIII Corps, which was to attack the Dimmock Line east of the city. The third was 1,300 cavalrymen under Brig. Gen. August Kautz, who were to sweep around Petersburg and strike it from the southeast. The troops moved out on the night of June 8, but made poor progress. Eventually the infantry crossed by 3:40 a.m. on June 9 and by 7 a.m., both Gillmore and Hinks had encountered the enemy, but stopped at their fronts. Gillmore told Hinks that he would attack but that both of the infantry columns should await the cavalry assault from the south.
  Kautz's men did not arrive until noon, however, having been delayed en route by numerous enemy pickets. They assaulted the Dimmock Line where it crossed the Jerusalem Plank Road (present-day U.S. Route 301, Crater Road). The Confederates' Battery 27, also known as Rives's Salient, was manned by 150 militiamen commanded by Maj. Fletcher H. Archer. Kautz first launched a probing attack, then paused. His main attack was by the 11th Pennsylvania Cavalry against the Home Guard, a group consisting primarily of teenagers, elderly men, and some wounded soldiers from city hospitals. The Home Guards retreated to the city with heavy losses, but by this time Beauregard had been able to bring reinforcements from Richmond to bear, which were able to repulse the Union assault. Kautz, hearing no activity on Gillmore's front, presumed that he was left on his own and withdrew. Confederate casualties were about 80, Union 40. Butler was furious with Gillmore's timidity and incompetence and arrested him. Gillmore requested a court of inquiry, which was never convened, but Grant later reassigned him and the incident was dropped.
