American Civil War prison camps


American Civil War Prison Camps were operated by both the Union and the Confederacy to handle the 409,000 soldiers captured during the war from 1861 to 1865. The Record and Pension Office in 1901 counted 211,000 Northerners who were captured. In 1861-63 most were immediately paroled; after the parole exchange system broke down in 1863, about 195,000 went to prison camps. Some tried to escape but few succeeded. By contrast 464,000 Confederates were captured and 215,000 imprisoned. Over 30,000 Union and nearly 26,000 Confederate prisoners died in captivity. Just over 12% of the captives in Northern prisons died, compared to 15.5% for Southern prisons.

Parole

Lacking means for dealing with large numbers of captured troops early in the American Civil War, the Union and Confederate governments both relied on the traditional European system of parole and exchange of prisoners. A prisoner who was on parole promised not to fight again until his name was "exchanged" for a similar man on the other side. Then both of them could rejoin their units. While awaiting exchange, prisoners were briefly confined to permanent camps. The exchange system broke down in mid 1863 when the Confederacy refused to treat captured black prisoners as equal to white prisoners. The prison populations on both sides then soared. There were 32 major Confederate prisons, 16 of them in the Deep South states of Georgia, Alabama, and South Carolina. Training camps were often turned into prisons, and new prisons also had to be made. The North had a much larger population than the South, and Gen. Ulysses S. Grant was well aware that keeping its soldiers in Northern prisons hurt the Southern economy and war effort.

Prisoner exchanges

At the outbreak of the War the Federal government avoided any action, including prisoner exchanges, that might be viewed as official recognition of the Confederate government in Richmond. Public opinion forced a change after the First Battle of Bull Run, when the Confederates captured over one thousand Union soldiers.
Union and Confederate forces exchanged prisoners sporadically, often as an act of humanity between opposing commanders. Support for prisoner exchanges grew throughout the initial months of the war, as the North saw increasing numbers of its soldiers captured. Petitions from prisoners in the South and editorials in Northern newspapers brought pressure on the Lincoln administration. On December 11, 1861, the US Congress passed a joint resolution calling on President Lincoln to "inaugurate systematic measures for the exchange of prisoners in the present rebellion." In two meetings on February 23 and March 1, 1862, Union Major Gen. John E. Wool and Confederate Brig. Gen. Howell Cobb met to reach an agreement on prisoner exchanges. They discussed many of the provisions later adopted in the Dix-Hill agreement. However, differences over which side would cover expenses for prisoner transportation stymied the negotiations.

Dix-Hill Cartel of 1862

Prison camps were largely empty in mid-1862, thanks to the informal exchanges. Both sides agreed to formalize the system. Negotiations resumed in July 1862, when Union Maj. Gen. John A. Dix and Confederate Maj. Gen. D. H. Hill were assigned the task. The agreement established a scale of equivalents for the exchange of military officers and enlisted men. Thus a navy captain or an army colonel was worth fifteen privates or ordinary seamen, while personnel of equal ranks were exchanged man for man. Each government appointed an agent to handle the exchange and parole of prisoners. The agreement also allowed the exchange of non-combatants, such as citizens accused of "disloyalty", and civilian employees of the military, and allowed the informal exchange or parole of captives between the commanders of the opposing forces.
Authorities were to parole any prisoners not formally exchanged within ten days following their capture. The terms of the cartel prohibited paroled prisoners from returning to the military in any capacity including "the performance of field, garrison, police, or guard, or constabulary duty."

End of exchanges

The exchange system collapsed in 1863 because the Confederacy refused to treat black prisoners the same as whites. They said they were probably ex-slaves and belonged to their masters, not to the Union Army. The South needed the exchanges much more than the North did, because of the severe manpower shortage in the Confederacy. In 1864 Ulysses Grant, noting the "prisoner gap", decided that the growing prisoner gap gave him a decided military advantage. He therefore opposed wholesale exchanges until the end was in sight. Around 5600 Confederates were allowed to join the Union Army. Known as "Galvanized Yankees" these troops were stationed in the West facing Native Americans.
Prisoner exchanges resumed early in 1865, just before the war's end, with the Confederates sending 17,000 prisoners North while receiving 24,000 men. On April 23, after the war ended, the riverboat Sultana was taking 1900 ex-prisoners North on the Mississippi River when it exploded, killing about 1500 of them.

Death rates

The overall mortality rates in prisons on both sides were similar, and quite high. Many Southern prisons were located in regions with high disease rates, and were routinely short of medicine, doctors, food and ice. Northerners often believed their men were being deliberately weakened and killed in Confederate prisons, and demanded that conditions in Northern prisons be equally harsh, even though shortages were not a problem in the North.
About 56,000 soldiers died in prisons during the war, accounting for almost 10% of all Civil War fatalities. During a period of 14 months in Camp Sumter, located near Andersonville, Georgia, 13,000 of the 45,000 Union soldiers confined there died. At Camp Douglas in Chicago, Illinois, 10% of its Confederate prisoners died during one cold winter month; and Elmira Prison in New York state, with a death rate of 25%, very nearly equaled that of Andersonville.
