During the American Civil War, no military prison gained a darker reputation than Camp Sumpter, better known as Andersonville. Located in Georgia, this Confederate stockade became the site of one of the conflict’s most severe humanitarian catastrophes, holding tens of thousands of Union soldiers in conditions so brutal that an estimated 100 prisoners died per day at the height of its overcrowding in 1864. The camp was originally designed to hold about 10,000 captives. By mid-1864, that number had swelled past 30,000, and over the course of the war, roughly 45,000 Union soldiers were held within its walls.
This overcrowding created a breeding ground for disease, exhaustion, and death on a scale that shocked even those who had already witnessed the war’s devastation. Union Private Prescott Tracy, held captive at Andersonville, left detailed accounts of the conditions. He described prisoners arriving with nearly no clothing, noting that footwear was rare and that only recent arrivals typically had both coats and pants. Most men had only partial clothing, and many had almost none at all.
Shelter was equally scarce, with prisoners fashioning makeshift tents from thin coats or scraps of cloth, while the majority remained fully exposed to rain and sun. The only water source for the entire camp was a narrow stream that ran through the center of the stockade. Tracy recalled that the water was dark in color with heavy sediment settling at the bottom of any container. The contamination was worsened by the camp’s layout: the Confederate cookhouse sat directly upstream and regularly dumped spoiled food waste into the water, creating a greasy film across the surface.
Confederate guards also disposed of large amounts of unsanitary waste into the same stream. Despite being more like an open drainage channel than a waterway, it remained the prisoners’ only option for drinking, cooking, and washing. A system known as the deadline further enforced the camp’s grim reality. A wooden board nailed to waist-high stakes ran around the entire perimeter.
Guards had standing orders to shoot anyone who crossed or even touched the line. Union soldier John Levi Mail described how a sick prisoner who merely leaned against the boundary for support could trigger a lethal response. Since warning shots were not part of the protocol, stray bullets also endangered nearby prisoners. Discipline was harsh.
Prisoners caught stealing from fellow inmates were placed in wooden stocks or made to wear heavy chains. If even one prisoner was unaccounted for during roll call, guards withheld rations from the entire group, worsening an already desperate food situation. John L. Ransom, a Union prisoner, recorded witnessing a fellow inmate who was ill, disoriented, and lightly clothed walking slowly toward the camp’s boundary.
The guards responded immediately with force, and the man collapsed near the edge of the camp. Ransom wrote that perhaps the man had chosen a quicker end over prolonged suffering. Food rations were shockingly inadequate. Weekly provisions consisted mainly of cornbread made from ground corn cobs and only four tablespoons of rice.
When meat was included, it was often spoiled pork. Tracy described how guards dropped the rations directly onto the ground each day at 4 p. m. Most prisoners ate everything at once because there was no guarantee food would come the next day, and uneven distribution meant some received nothing at all.
The hardships began even before reaching the prison; Tracy recalled that on a five-day march to the camp, prisoners received only 13 crackers in total. The physical environment added another layer of torment. Almost all vegetation had been worn away by thousands of footsteps, leaving dry, dusty earth with no natural shade. Private Ezra H.
Ripple described how prisoners used scraps of fabric to build small shelters. He and eight others huddled in one tiny structure, their feet stretched outward like the spokes of a wheel, each man trying to claim a sliver of shade. Albert Harry Shatzel wrote in his diary about the intense heat, sandy ground, and the overpowering odor from the lack of sanitation, noting the air was so thick with unpleasant smells it was hard to breathe. Disease swept through the overcrowded camp with devastating effect.
Dr. John M. Howell, an acting assistant surgeon at Andersonville, documented the physical state of prisoners upon his arrival. He described men as barely recognizable, sick, frail, often lacking clothing, and many near the end of their strength, expected to die within hours or days.
Cases of gangrene alarmed Howell the most. In some individuals, the infection had eroded tissue down to the bone. Ezra Ripple later recalled that aside from death itself, the thing most dreaded by prisoners was gangrene. In severe cases, surgeons had to remove affected limbs, and Ripple remembered seeing the exposed bone appear pale and gleaming during procedures, an image that stayed with him for life.
The hospital offered little refuge. Between February 25 and May 9, 1864, the prison hospital saw 4,588 patients, with 1,026 dying from illness. Tracy, who worked as a hospital clerk, described witnessing collections of bodies waiting to be taken for burial. The death rate in the earlier months was around 30 per day, but by the time he left, it had risen sharply to an average of over 130 daily deaths.
On one particularly grim day, the total reached 146. The main causes were diarrhea, dysentery, and scurvy, made deadly by poor sanitation, inadequate nutrition, and a lack of medical supplies. When prisoners died, their fellow inmates were responsible for burial. Tracy described how these duties were performed under guard with little time for reflection.
Twenty-five bodies were placed in a single pit without markers. In some cases, prisoners were given a few sticks of firewood as payment for the grim work, which occasionally led to quarrels among desperate men competing for the opportunity. Union soldier Albert Harry Shatzel wrote in his diary about the grim regularity of death, noting that many men would go to sleep and never wake again. On average, between 25 and 30 individuals were carried out each day by their fellow prisoners and placed into prepared burial trenches with a simple board laid across the top.
Despite the suffering, most prisoners refused offers of release that came at a moral price. Confederate authorities occasionally allowed Union soldiers to secure freedom by pledging loyalty to the Confederacy, some with financial incentives offered. Tracy observed that very few accepted. He recounted a fellow prisoner who sent a message home to his mother: “My time here is taking a toll on me, mother, but I face it with pride for the sake of my country.
”
Some prisoners attempted escape by digging tunnels under the walls. Union soldier John Levi Mail recalled how men worked at night using whatever tools they could find, concealing fresh earth by placing it in their pockets and scattering it as they walked during the day. Prisoners too ill to move lay across tunnel openings to hide them from guards. Eventually, Confederate officials responded by ordering enslaved laborers to stack pitch pine logs around the stockade and set them on fire at night, creating a bright ring of light that made digging or moving undetected nearly impossible.
The dense smoke drifted over the prison, deepening the sense of isolation. Other escape attempts were desperate and dangerous. John Ransom described a method where a man would pretend to be dead and allow himself to be carried on a stretcher and left among the bodies. Once darkness fell, the “dead man” would rise and attempt to run away, hoping to evade the guards.
It was a strategy born of extreme desperation, reflecting both the will to escape and the dehumanizing nature of the camp. Samuel J. Gibson, a prisoner who kept a diary, described Andersonville as a place of overwhelming misery and hardship, a place testing the very limits of human endurance. As the heat grew worse, he noted that three out of four men in his small group had fallen ill.
Weeks later, he reflected that if the camp was not the worst place imaginable, it was close to it, writing that he hoped never to encounter anything more severe. Camp Sumpter Cemetery, filled with mass graves from the prison, became one of the most sobering symbols of Civil War captivity. The camp’s history stands as a documented record of how overcrowding, neglect, and inadequate resources turned a prison into a site of immense tragedy, remembered through the firsthand accounts of the men who endured it and, in many cases, did not survive to tell their stories.
