AP Syllabus focus:
‘Union victory was also aided by the wartime destruction of the South’s infrastructure.’
The Union’s adoption of total war transformed the Civil War’s final years, targeting Confederate armies, resources, and civilian infrastructure to break Southern resistance and hasten surrender.
Total War and the Transformation of Union Strategy
Union military strategy evolved significantly after 1862 as leaders sought methods to end the prolonged conflict. By 1864, under General Ulysses S. Grant’s overall command, the Union embraced total war, a strategy that targeted not only enemy armies but also the economic and logistical structures enabling Confederate resistance. The shift marked a deliberate escalation that aimed to erode the South’s capacity and willingness to continue fighting.
Total War: A military strategy that targets an opponent’s armed forces as well as the economic, political, and civilian resources sustaining its war effort.
This approach grew out of frustration with previous limited war strategies, which had failed to break Confederate resolve or destroy its war-making capacity. Unlike earlier campaigns focused on occupying territory or forcing set-piece battles, total war sought systemic destruction.
Grant’s Coordinated Offensives
Grant’s direction introduced unprecedented coordination across multiple Union armies. Rather than allowing Confederate forces to shift troops between theaters, Grant ordered simultaneous offensives designed to apply continuous pressure.
Key elements included:
Overland Campaign (1864): Grant repeatedly engaged Robert E. Lee’s Army of Northern Virginia, accepting high casualties to prevent Confederate withdrawal or reinforcement.
Siege of Petersburg: Targeted the crucial rail networks supplying Richmond, attempting to sever the Confederacy’s logistical lifelines.
Western offensives under Sherman: Enabled parallel pressure on Confederate armies in the Deep South.
This unified approach reflected Grant’s belief that the Confederacy could be defeated only by destroying both its armies and its infrastructure.
Sherman and the Logic of Destruction
General William Tecumseh Sherman became the most prominent practitioner of total war. His campaigns in Georgia and the Carolinas targeted railways, factories, crops, and other assets essential to Southern survival. Sherman argued that crippling the Confederate home front would erode morale and hasten the end of the war.
The Atlanta Campaign and Its Aftermath
After months of maneuvering, Sherman captured Atlanta in September 1864—an industrial and railway hub vital to the Confederacy. The city’s fall:
Boosted Northern morale and helped secure Lincoln’s reelection.
Severed major Southern supply routes.
Demonstrated the vulnerability of the Deep South.
Sherman ordered the evacuation and destruction of military and industrial facilities, claiming such measures were necessary to ensure that Atlanta could not support Confederate operations again.
The March to the Sea
Sherman’s March to the Sea (November–December 1864) became the emblem of total war.

…destroying infrastructure to undermine the South’s will to fight.
Key characteristics included:
Destruction of railroads, often using “Sherman’s neckties,” twisted rails rendered unusable.
Foraging operations that seized food, livestock, and supplies to sustain Union troops while depriving Confederates.
Targeted burning of warehouses, mills, and factories linked to the Southern war economy.
Psychological warfare, demonstrating that Confederate armies could not protect the interior.
Sherman insisted civilians were not to be directly harmed, yet the campaign inflicted immense hardship by eliminating the material foundations of Southern life.
Impact on Southern Society and Infrastructure
The Union’s destructive campaigns produced widespread devastation in the Confederate states. Total war disrupted agriculture, transportation, and communication across the region.

The image includes specific details of Atlanta’s destruction not required by the syllabus but vividly illustrates total war in action. Source.
Major impacts included:
Collapse of plantation production as rail lines and supply networks disintegrated.
Shortages of food and goods, intensifying civilian suffering.
Destruction of public buildings, factories, and bridges, reducing the South’s capacity to sustain armies.
Displacement of enslaved people who fled plantations, further weakening the Confederate labor system.
The South’s dependence on railroads made it particularly vulnerable. Grant and Sherman targeted trunk lines and depots, knowing the Confederacy lacked the industrial capacity to replace destroyed equipment.
Undermining Confederate Morale and Military Capacity
Total war’s psychological effects were as significant as its economic consequences. As Union armies advanced and devastation increased, many Southern civilians doubted the Confederacy’s ability to protect them. This erosion of morale contributed to desertions within Confederate ranks and declining civilian support for the war.
Military consequences included:
Reduced ability to move and supply Confederate armies.
Loss of vital manufacturing sites for weapons and ammunition.
Forced dispersal of Confederate forces to defend key points, weakening their strategic coherence.
The destruction also directly supported Union battlefield success. For instance, the fall of Atlanta and the depletion of Confederate supplies accelerated the weakening of Lee’s army in Virginia.
How Total War Aided Union Victory
Total war helped achieve the Union’s overarching goal of breaking the Confederacy’s capacity to resist. This strategy:
Complemented battlefield victories by ensuring the South could not rebuild armies or infrastructure.
Shortened the conflict by making continued resistance untenable.
Strengthened Northern resolve as victories demonstrated progress.
Ensured that when Confederate armies surrendered in 1865, the South was incapable of sustaining further large-scale rebellion.
By systematically dismantling the South’s physical and psychological ability to wage war, total war became a decisive factor in securing Union victory and fulfilling the AP syllabus focus on the wartime destruction of Southern infrastructure.

FAQ
Civilians often resorted to informal networks of barter and mutual aid as traditional markets collapsed. The destruction of rail lines made it difficult to transport food and goods, forcing many communities into forms of local subsistence.
Women played a central role in maintaining household stability, managing scarce resources, and organising neighbourhood support, even as inflation and shortages worsened.
Some civilians fled approaching Union forces, while others complained directly to Confederate authorities, highlighting declining morale long before formal surrender.
Union troops frequently implemented systematic methods of destruction to ensure Confederate railways could not be repaired quickly.
Common tactics included:
Heating rails over fires and twisting them into “Sherman’s neckties”
Burning wooden sleepers to make reassembly impossible
Demolishing depots, switches, and machine shops
Uprooting track sections and scattering components
These practices aimed to break the logistical backbone of Confederate armies rather than merely delay their movement.
Enslaved people often approached Union columns seeking freedom, information, or protection. Many provided guides, labour, and intelligence that aided Union operations.
However, Sherman’s army could not always accommodate the large numbers who followed, leading to difficult decisions about mobility and supply.
Despite such challenges, the march significantly accelerated self-emancipation across Georgia and the Carolinas, undermining the labour force on which the Confederacy relied.
The destruction of infrastructure directly hindered the movement of officials, communication between departments, and the operation of courts.
Key effects included:
Loss of tax revenues due to collapsed agriculture
Inability to distribute supplies or enforce conscription
Displacement or death of local administrative staff
Breakdown of law enforcement as communities prioritised survival
By late 1864, several state governments were effectively paralysed, further eroding Confederate cohesion.
Many newspapers initially attempted to frame Union advances as temporary setbacks, but as destruction mounted, editorial tone shifted sharply.
Some editors warned readers of the Confederacy’s deteriorating situation, emphasising the inability of Confederate armies to protect civilians. Others encouraged continued resistance, portraying Sherman’s actions as evidence of Northern brutality.
These conflicting narratives reveal growing internal divisions and the psychological strain total war placed on the Confederate public.
Practice Questions
Question 1 (1–3 marks)
Explain one way in which the Union’s use of total war during Sherman’s March to the Sea weakened the Confederacy’s ability to continue fighting.
Mark Scheme:
1 mark for identifying a relevant way total war weakened the Confederacy (e.g., destruction of railways, seizure of supplies).
1 mark for describing how this action disrupted Confederate military operations or civilian support.
1 mark for explaining why this weakening made continued Confederate resistance more difficult (e.g., reduced mobility, supply shortages, collapse of morale).
Question 2 (4–6 marks)
Assess the extent to which the destruction of Southern infrastructure contributed to the Union victory in the later stages of the Civil War.
Mark Scheme:
1–2 marks for describing specific examples of infrastructure destruction (e.g., railroads, factories, public buildings, crops).
1–2 marks for explaining how these actions undermined Confederate military capacity or morale (e.g., inability to supply armies, loss of transportation networks, psychological impact).
1–2 marks for evaluating the significance of this factor compared with other contributors to Union victory (e.g., Grant’s overall strategy, manpower advantages, key battlefield victories).
Full marks require a balanced argument that references both infrastructure destruction and alternative factors.
