Henry Wirz was an officer from the Confederate Army during the American Civil War. He is best known for being the commandant of the stockade of Camp Sumter, a camp for prisoners of war near Andersonville, Georgia. This site was famous for its terrible conditions and the high mortality rate of the prisoners which were confined here. The place had not been constructed as it was originally designed. It was smaller than what was originally planned. Due to this, its capacity was rapidly surpassed by the arrival of Union prisoners. The construction of wooden barracks were one of the tasks that were originally planned. However, this never materialized. This caused the Confederates to incarcerate the prisoners in a vast stockade with no roof. It had 16 and a half acres and had been intended to be used as a temporary prison for future exchanges of prisoners with the Union.

The place, nicknamed "Andersonville", suffered from overcrowding, poor sanitary conditions, a lack of food, tools, medical supplies, and potable water. Wirz recognized that the conditions were inadequate and petitioned his superiors to provide more support, but was denied.  At its peak in August 1864, the camp held approximately 32,000 Union prisoners. The monthly mortality rate reached 3,000 people. Causes of mortality were related to disease, dysentery, and malnutrition  Around 45,000 prisoners were incarcerated during the existence and operation of the camp. 13,000 of those, representing around 28%, died. As a result, he was charged for "combining, confederating, and conspiring to injure the health and destroy the lives of soldiers of the United States".
