Battle of the American Civil War
The Third Battle of Petersburg, also known as the Breakthrough at Petersburg or the Fall of Petersburg, was fought on April 2, 1865, south and southwest Virginia in the area of Petersburg, Virginia, at the end of the 292-day Richmond–Petersburg Campaign (sometimes called the Siege of Petersburg) and in the beginning stage of the Appomattox Campaign near the conclusion of the American Civil War. The Union Army (Army of the Potomac, Army of the Shenandoah and Army of the James) under the overall command of General-in-Chief Lieutenant General Ulysses S. Grant, launched an assault on General Robert E. Lee's Confederate Army of Northern Virginia's Petersburg, Virginia, trenches and fortifications after the Union victory at the Battle of Five Forks on April 1, 1865. As a result of that battle the Confederate right flank and rear were exposed. The remaining supply lines were cut and the Confederate defenders were reduced by over 10,000 men killed, wounded, taken prisoner or in flight.
The thinly held Confederate lines at Petersburg had been stretched to the breaking point by earlier Union movements that extended those lines beyond the ability of the Confederates to man them adequately and by desertions and casualties from recent battles. As the much larger Union forces assaulted the lines, desperate Confederate defenders held off the Union breakthrough long enough for Confederate government officials and most of the remaining Confederate army, including local defense forces and some Confederate Navy personnel, to flee Petersburg and the Confederate capital of Richmond, Virginia, during the night of April 2–3. Confederate corps commander Lieutenant General A.P. Hill was killed during the fighting.
Union soldiers occupied Richmond and Petersburg on April 3, 1865, but most of the Union Army pursued the Army of Northern Virginia until they surrounded it, forcing Robert E. Lee to surrender that army on April 9, 1865, after the Battle of Appomattox Court House, Virginia.
Background.
Siege of Petersburg.
The 292-day Richmond–Petersburg Campaign (Siege of Petersburg) began when two corps of the Union Army of the Potomac, which were unobserved when leaving Cold Harbor at the end of the Overland Campaign, combined with the Union Army of the James outside Petersburg, but failed to seize the city from a small force of Confederate defenders at the Second Battle of Petersburg on June 15–18, 1864. Union General-in-Chief Ulysses S. Grant then had to conduct a campaign of trench warfare and attrition in which the Union forces tried to wear down the smaller Confederate Army, destroy or cut off sources of supply and supply lines to Petersburg and Richmond and extend the defensive lines which the outnumbered and declining Confederate force had to defend to the breaking point. The Confederates were able to defend Richmond and the important railroad and supply center of Petersburg, Virginia, south of Richmond for over nine months against a larger force by adopting a defensive strategy and skillfully using trenches and field fortifications.
After the Battle of Hatcher's Run on February 5–7, 1865, extended the lines another , Lee had few reserves after manning the lengthened defenses. Lee knew that his forces could not sustain the defenses much longer and the best chance to continue the war was for part or all of his army to leave the Richmond and Petersburg lines, obtain food and supplies at Danville, Virginia, or possibly Lynchburg, Virginia, and join General Joseph E. Johnston's force opposing Major General William T. Sherman's army in North Carolina. If the Confederates could quickly defeat Sherman, they might turn back to oppose Grant before he could combine his forces with Sherman's. Lee began preparations for the movement and informed Confederate President Jefferson Davis and Confederate States Secretary of War John C. Breckinridge of his conclusions and plan.
Under pressure from President Jefferson Davis to maintain the defenses of Richmond and unable to move effectively over muddy roads with poorly fed animals in winter in any event, General Lee accepted a plan by Major General John B. Gordon to launch an attack on Union Fort Stedman designed to break Union lines east of Petersburg or at least compel Grant to shorten the Union Army lines. If this were to be accomplished, Lee would have a better chance to shorten the Confederate lines and send a substantial force, or nearly his whole army, to help Joe Johnston.
Gordon's surprise attack on Fort Stedman in the pre-dawn hours of March 25, 1865, captured the fort, three adjacent batteries and over 500 prisoners while killing and wounding about 500 more Union soldiers. The Union IX Corps under Major General John G. Parke promptly counterattacked. The IX Corps recaptured the fort and batteries, forced the Confederates to return to their lines and in places to give up their advance picket line. The IX Corps inflicted about 4,000 casualties, including about 1,000 captured, whom the Confederates could ill afford to lose.
On the afternoon of March 25, 1865, at the Battle of Jones's Farm, the II Corps and VI Corps captured Confederate picket lines near Armstrong's Mill which extended the left end of the Union line about closer to the Confederate fortifications. This put the VI Corps within about of the Confederate line. After the Confederate defeats at Fort Stedman and Jones's Farm, Lee knew that Grant soon would move against the only remaining Confederate supply lines to Petersburg, the South Side Railroad and the Boydton Plank Road, and possibly cut off all routes of retreat from Richmond and Petersburg.
Beginning of Appomattox Campaign.
Grant's orders.
On March 24, 1865, the day before the Confederate attack on Fort Stedman, Grant already planned for an offensive to begin March 29, 1865. The objectives were to draw the Confederates out into an open battle where they might be defeated and, if the Confederates held their lines, to cut the remaining road and railroad supply and communication routes between areas of the Confederacy still under Confederate control and Petersburg and Richmond. The Battle of Fort Stedman had no effect on Grant's plans. The Union Army lost no ground due to the attack, did not need to contract their lines and suffered casualties that were only a small percentage of their force.
Grant ordered Major General Edward Ord to move part of the Army of the James from the lines near Richmond to fill in the line to be vacated by the II Corps under Major General Andrew A. Humphreys at the southwest end of the Petersburg line before that corps moved to the west. This freed two corps of Major General George Meade's Army of the Potomac for offensive action against Lee's flank and railroad supply lines: Major General Andrew A. Humphrey's II Corps and the V Corps commanded by Major General Gouverneur K. Warren. Grant ordered the two infantry corps, along with Major General Philip Sheridan's cavalry corps, still designated the Army of the Shenandoah under Sheridan's command, to move west. Sheridan's cavalry consisted of two divisions commanded by Brigadier General Thomas Devin and Brigadier General (Brevet Major General) George Armstrong Custer but under the overall command of Brigadier General (Brevet Major General) Wesley Merritt, as an unofficial corps commander, and the division of Major General George Crook detached from the Army of the Potomac. Grant's objectives remained the same although he thought it unlikely the Confederates would be drawn into open battle.
Lee's orders.
Confederate General-in-chief Robert E. Lee, who was already concerned about the ability of his weakening army to maintain the defense of Petersburg and Richmond, realized that the Confederate defeat at Fort Stedman would encourage Grant to make a move against his right flank and communication and transportation routes. On the morning of March 29, 1865, Lee prepared to send some reinforcements to the western end of his line and began to form a mobile force of about 10,600 infantry, cavalry and artillery under the command of Major General George Pickett and cavalry commander Major General Fitzhugh Lee. This force would go beyond the end of the line to protect the key junction at Five Forks in Dinwiddie County from which a Union force could access the remaining open Confederate roads and railroads.
Union troop movements.
Before dawn on March 29, 1865, Warren's V Corps moved west of the Union and Confederate lines while Sheridan's cavalry took a longer, more southerly route toward Dinwiddie Court House. Humphrey's II Corps filled the gap between the existing end of the Union line and the new position of Warren's corps. Warren's corps led by Brigadier General Joshua Chamberlain's First Brigade of Brigadier General (Brevet Major General) Charles Griffin's First Division of the V Corps proceeded north on the Quaker Road toward its intersection with the Boydton Plank Road and the Confederates' nearby White Oak Road Line.
Battle of Lewis's Farm.
Along Quaker Road, across Rowanty Creek at the Lewis Farm, Chamberlain's men encountered brigades of Confederate Brigadier Generals Henry A. Wise, William Henry Wallace and Young Marshall Moody which had been sent by Fourth Corps commander Lieutenant General Richard H. Anderson and his only present division commander, Major General Bushrod Johnson, to turn back the Union advance. A back-and-forth battle ensued during which Chamberlain was wounded and almost captured. Chamberlain's brigade, reinforced by a four-gun artillery battery and regiments from the brigades of Colonel (Brevet Brigadier General) Edgar M. Gregory and Colonel (Brevet Brigadier General) Alfred L. Pearson, who was later awarded the Medal of Honor, drove the Confederates back to their White Oak Road Line. Casualties for both sides were nearly even at 381 for the Union and 371 for the Confederates.
After the battle, Griffin's division moved up to occupy the junction of the Quaker Road and Boydton Plank Road near the end of the Confederate White Oak Road Line. Late in the afternoon of March 29, 1865, Sheridan's cavalry occupied Dinwiddie Court House on the Boydton Plank Road without opposition. The Union forces had cut the Boydton Plank Road in two places and were close to the Confederate line and in a strong position to move a large force against both the Confederate right flank and the crucial road junction at Five Forks in Dinwiddie County to which Lee was just sending Pickett's mobile force defenders. The Union Army was nearly in position to attack the two remaining Confederate railroad connections with Petersburg and Richmond, if they could take Five Forks.
Encouraged by the Confederate failure to press their attack at Lewis's Farm and their withdrawal to their White Oak Road Line, Grant decided to expand Sheridan's mission to a major offensive rather than just a possible battle or a railroad raid and forced extension of the Confederate line.
Battle of White Oak Road.
On the morning of March 31, General Lee inspected his White Oak Road Line and learned that the Union left flank held by Brigadier General Romeyn B. Ayres's division had moved forward the previous day and was "in the air." A wide gap also existed between the Union infantry and Sheridan's nearest cavalry units near Dinwiddie Court House. Lee ordered Major General Bushrod Johnson to have his remaining brigades under Brigadier General Henry A. Wise and Colonel Martin L. Stansel in lieu of the ill Young Marshall Moody, reinforced by the brigades of Brigadier Generals Samuel McGowan and Eppa Hunton, attack the exposed Union line.
Stansel's, McGowan's and Hunton's brigades attacked both most of Ayres's division and all of Crawford's division which quickly had joined the fight as it erupted. In this initial encounter, two Union divisions of over 5,000 men were thrown back across Gravelly Run by three Confederate brigades. Brigadier General (Brevet Major General) Charles Griffin's division and the V Corps artillery under Colonel (Brevet Brigadier General) Charles S. Wainwright finally stopped the Confederate advance short of crossing Gravelly Run. Adjacent to the V Corps, Major General Andrew A. Humphreys conducted diversionary demonstrations and sent two of Brigadier General (Brevet Major General) Nelson Miles's brigades from his II Corps forward. They initially surprised and, after a sharp fight, drove back Wise's brigade on the left of the Confederate line, taking about 100 prisoners.
At 2:30 p.m., Brigadier General Joshua Chamberlain's men forded the cold, swollen Gravelly Run, followed by the rest of Griffin's division and then the rest of Warren's reorganized corps. Under heavy fire, Chamberlain's brigade, along with Colonel (Brevet Brigadier General) Edgar M. Gregory's brigade, charged Hunton's brigade and drove Hunton's troops back to the White Oak Road Line, which allowed Chamberlain's and
