Battle of Nashville
From Historic Maps to Geophysics

Why Nashville?
On the eve of the Civil War, the North boasted a well-developed and interconnected transport infrastructure of railways and canals. The South lacked a comparably unifying infrastructural network. A rare Southern city possessing both railroad and riverine transportation infrastructure, and the key to entering the rest of Tennessee and the Lower South, Nashville became a coveted target for both the Union and the Confederacy.
Pre 1862
Nashville emerged as an important commercial center, thanks to its strategic location along the Cumberland River and major railroads. It became a hub for trade and transportation in the South, with industries like tobacco, cotton, and livestock contributing to its economy.
The city had a diverse population, including a significant number of free African Americans, as well as enslaved people. This mix contributed to a complex social fabric, with both pro-Union and pro-Confederate sentiments present among residents.
Nashville was part of a slave-holding state, and tensions were rising in the years leading up to the Civil War. Debates over states' rights and slavery were prominent, reflecting the broader national conflict.
The city developed robust infrastructure, including railroads, telegraph lines, and roads, which facilitated communication and transportation and made it an attractive target for military operations during the war.
Nashville 1862
In February 1862, after the Union victories at Fort Henry and Fort Donelson, Nashville fell to Union forces under General Don Carlos Buell. This marked the first Confederate state capital to be captured by Union troops.
The Union forces fortified Nashville with extensive defensive works, including fortifications that would protect the city from potential Confederate counterattacks. Notable forts included Fort Negley, which was one of the largest earthwork forts built during the war.
"We are informed that Nashville will make no resistance and we again hope that we may not be disturbed but everybody is on the move...thousands have left town and are still going, leaving their houses empty."
The occupation brought significant social changes. The local population faced shortages of goods and rising prices. The presence of Union soldiers also affected daily life, leading to tensions between Unionists and Confederate sympathizers.
The city became a refuge for freed slaves and those seeking safety from the conflict. Nashville’s cultural landscape began to change, influenced by the influx of soldiers and displaced individuals.
Nashville 1863
Nashville continued to serve as a crucial Union stronghold during the Civil War, marked by several significant developments. The city became a key logistical hub for Union operations in the Western Theater. It supported major campaigns, including the Battle of Chattanooga, where Union forces aimed to secure control over strategic routes.
The city’s defenses were further strengthened, with extensive fortifications built to protect against potential Confederate attacks. Fort Negley, in particular, was expanded and became one of the largest forts in the South.
The Union occupation altered the social dynamics of Nashville. Many residents experienced economic hardship due to wartime shortages, while the presence of Union troops led to increased tensions, especially among Confederate sympathizers.
The occupation created opportunities for freed African Americans, who flocked to Nashville seeking refuge and employment. The city became a center for education and activism within the African American community.
Nashville 1864
Nashville was fortified and served as a critical supply base for Union forces. The city housed a large garrison, which helped support military campaigns throughout Tennessee and beyond.
The most significant event of the year was the Battle of Nashville, fought from December 15 to 16, 1864. Union General George H. Thomas led the Army of the Cumberland in a decisive victory against Confederate General John Bell Hood’s Army of Tennessee. This battle effectively crushed Hood's forces and marked a turning point in the Western Theater.
The ongoing military presence and battles brought challenges for Nashville's civilian population, including shortages of goods, inflation, and disruptions to daily life. However, the Union occupation also provided some stability compared to the chaos of wartime.
The African American community in Nashville continued to grow, with many freed slaves joining the Union Army or finding work in support roles. The city became a center for education and social activism within the African American community.
Nashville 1865
"Thomas, in the meantime, was making his preparations to receive Hood. The road to Chattanooga was still well guarded with strong garrisons at Murfreesboro, Stevenson, Bridgeport and Chattanooga. Thomas had previously given up Decatur and had been reinforced by A. J. Smith’s two divisions just returned from Missouri. He also had Steedman’s division and R. S. Granger’s, which he had drawn from the front. His quartermaster’s men, about ten thousand in number, had been organized and armed under the command of the chief quartermaster, General J. L. Donaldson, and placed in the fortifications under the general supervision of General Z. B. Tower, of the United States Engineers"
As the war came to an end in April 1865, Nashville remained under Union control. The city was a base for Union troops and played a role in the final campaigns against Confederate forces.
The end of the war brought significant changes for Nashville's African American community. Many freedmen sought education and economic opportunities, leading to the establishment of schools and churches focused on community development.
While the war had officially ended, the Union military presence remained in Nashville for some time to maintain order and oversee the Reconstruction process. This continued military presence influenced local politics and social dynamics.
Ground Penetrating Radar
Survey work focused on several sites of historical and military importance from the occupation, fortification, and confrontation during the Battle of Nashville (Figure 3A and 3B). Site selection focused first on sites at threat from disturbance, and second on sites where private property access was attainable through access agreements. Surveys at Fort Negley and Shy’s Hill hoped to expand on prior 2021 & 2022 geophysical investigations to further characterize the nature and extent of fortification at Fort Negley, as well as military strategy and fortification at Shy’s Hill. Other sites—such as Granbury’s Lunette, and Redoubts 1, and 4—were crucial to Confederate defenses and may provide context to military strategy that led to Confederate defeats in the Battle of Nashville. All sites selected for the survey, except for Fort Negley, were locations of significant military engagement during the battle.
