History & Significance

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.

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, 23 miles (37 km) south of Richmond for over nine months against a larger force by adopting a defensive strategy and skillfully using trenches and field fortifications.

Historical context

The American Civil War (1861–1865) was the deadliest conflict in American history, killing an estimated 620,000 to 750,000 soldiers and an unknown number of civilians. The Confederate States of America, formed by eleven seceding Southern states, faced the Union in four years of warfare across 23 states and territories. Major engagements included First and Second Bull Run, Antietam (the bloodiest single day in American history, September 17, 1862), Chancellorsville, Gettysburg (July 1–3, 1863), Vicksburg (surrendered July 4, 1863), and Sherman's March through Georgia and the Carolinas (1864–1865). President Lincoln issued the Emancipation Proclamation on January 1, 1863, transforming the war's stated purpose to include the abolition of slavery and enabling the enlistment of approximately 180,000 Black men in the United States Colored Troops. Confederate General Robert E. Lee surrendered to Ulysses S. Grant at Appomattox Court House on April 9, 1865. The war resolved the question of secession and ended American slavery, though Reconstruction would face sustained resistance in its attempt to secure civil rights for formerly enslaved people.
