6.3 The Siege of Petersburg and the Fall of Richmond
4 min read•august 15, 2024
The siege of Petersburg and fall of Richmond marked a pivotal turning point in the Civil War. Union forces under Grant besieged the Confederate stronghold for nearly 10 months, slowly cutting off vital supply lines and wearing down Lee's army.
The loss of Petersburg and Richmond dealt a devastating blow to the Confederacy. It forced the Confederate government to flee, crippled their industrial capacity, and left Lee's army isolated. This paved the way for the final Confederate surrender at Appomattox Court House shortly after.

Key Terms to Review (19)
Attrition warfare: Attrition warfare is a military strategy that aims to wear down the enemy's strength through continuous losses in personnel and material. This approach focuses on depleting the opponent's resources rather than seeking quick victories, leading to a prolonged conflict. This tactic is often characterized by high casualty rates and heavy resource expenditure, and it plays a significant role in campaigns where one side seeks to outlast the other.
Battle of Globe Tavern: The Battle of Globe Tavern was a military engagement during the Siege of Petersburg, occurring from August 18 to August 21, 1864. This battle was part of the larger campaign aimed at cutting off Confederate supply lines and seizing control of vital transportation routes. The Union forces, under General Gouverneur K. Warren, aimed to capture a critical railroad junction, which played a key role in the ongoing efforts to secure Petersburg and ultimately Richmond.
Battle of the Crater: The Battle of the Crater was a significant military engagement that occurred on July 30, 1864, during the Siege of Petersburg in the American Civil War. This battle marked a pivotal moment where Union forces attempted to break the Confederate lines by detonating a massive mine beneath their fortifications, creating a large crater. The ensuing chaos and mismanagement led to heavy casualties and ultimately a failed assault for the Union army, demonstrating the complexities and difficulties of wartime leadership and strategy.
Blockade running: Blockade running refers to the act of ships attempting to evade naval blockades set up by opposing forces, particularly during wartime, to transport goods and supplies. This practice was crucial for the Confederacy during the Civil War as it allowed them to obtain necessary supplies and materials despite Union efforts to cut off their resources. Blockade runners often took advantage of their speed and knowledge of coastal geography to navigate through enemy lines.
Civilian suffering: Civilian suffering refers to the widespread pain, hardship, and trauma experienced by non-combatants during times of conflict, particularly in the context of warfare. This suffering can arise from direct violence, such as bombings and sieges, as well as from indirect effects like food shortages, displacement, and disease. During significant battles and military campaigns, the impact on civilians is profound, highlighting the often-overlooked human cost of war.
Confederate Army: The Confederate Army was the military force organized by the Confederate States of America during the American Civil War, primarily made up of soldiers from Southern states that seceded from the Union. This army was established to defend the Confederacy against Union forces and aimed to maintain slavery and Southern autonomy. The Confederate Army's structure included various branches, such as infantry, cavalry, and artillery, and it played a crucial role in significant battles throughout the war.
Destruction of infrastructure: Destruction of infrastructure refers to the severe damage or complete loss of essential facilities and systems that support a community's functionality, such as transportation networks, communication systems, and public services. In the context of military conflicts, particularly during the Civil War, this destruction often resulted from battles, sieges, and strategic attacks intended to cripple an opponent's ability to sustain war efforts. This not only affected immediate military operations but also had long-lasting impacts on civilian life and post-war recovery.
Evacuation of Richmond: The evacuation of Richmond occurred on April 2, 1865, when Confederate forces abandoned the capital of the Confederacy in response to Union advances. This significant event marked the collapse of Confederate defenses after a prolonged siege and led to the fall of Richmond, symbolizing a major turning point in the Civil War as Union forces closed in on the city and ultimately captured it shortly thereafter.
General Orders No. 1: General Orders No. 1 was an official directive issued by Union General Ulysses S. Grant on April 9, 1865, immediately following the surrender of Confederate General Robert E. Lee at Appomattox Court House. This order provided instructions to Union troops regarding the treatment of Confederate soldiers and emphasized the importance of maintaining order and discipline during the transition period following the end of hostilities. The order aimed to facilitate a peaceful reconciliation between the North and South as the Civil War came to a close.

These tactics were crucial during the prolonged engagement at Petersburg, where both the Union and Confederate forces employed various methods to either hold or break the siege, affecting the outcome of the Civil War significantly.
Strategic Supply Lines: Strategic supply lines refer to the routes and networks used to transport essential resources, such as food, ammunition, and equipment, to military forces during a conflict. In the context of the Siege of Petersburg and the Fall of Richmond, controlling these supply lines was vital for sustaining the Union and Confederate armies, as it directly impacted their ability to fight effectively. Disrupting the enemy's supply lines was a key strategy employed by both sides, highlighting the importance of logistics in warfare.
The terms of surrender: The terms of surrender refer to the specific conditions and agreements that are established when one party agrees to cease hostilities and capitulate to another party, often during military conflict. In the context of the Siege of Petersburg and the Fall of Richmond, these terms played a critical role in determining how the Confederate forces would formally acknowledge their defeat and transition to peace after years of warfare. Understanding the terms of surrender is vital for grasping the broader implications of military engagements and the eventual end of hostilities.
Total War: Total war is a military strategy that involves the complete mobilization of society's resources and the targeting of both enemy combatants and non-combatants to achieve total victory. This approach blurs the lines between soldiers and civilians, as it seeks to undermine the enemy's will to fight by destroying their economic and social infrastructure. In the context of the Civil War, this strategy marked a shift in warfare, reflecting the intense political and emotional stakes of the conflict.
Trench warfare: Trench warfare is a military strategy characterized by the construction of deep trenches to protect soldiers from enemy fire while they engage in combat. This method became prominent during the Civil War, particularly due to the high casualty rates and advances in weaponry, leading to prolonged standoffs where neither side could gain significant ground without incurring heavy losses.
