Someone told me recenly that a Confederate ancestor of his- a politician, and not a soldier- was captured in 1861 and not released until 1865. I found this odd, because of the prisoner exchanges that took place early in the war (before then end of prisoner exchanges over the refusal to exchange Confederates for USCT soldiers). Anyway, I'm really wondering if a politician was actually a POW (held at Camp Chase) during the entire war.
Civilian prisoners in US military custody were not included in the Prisoner exchanges between the US and Confederate authorities generally because they were not "belligerent" combatants related to the civil war as recognized by the US Government.
The United States did not recognize the Confederate civil authorities as any kind of Political government, but to the extent of its resistance to the United States an insurrectionary combination, etc. Given the scale of the situation, after mid-August, 1861, the entire inhabitants of the Southern States under Confederate sway were declared in insurrection against the laws of the Union, etc., until the conclusion of the conflict (unless the persons subscribed to the oath of allegiance, etc. in the mean time) and the Presidential proclamations of 1866 declaring a conclusion to that insurrection.
The US, however, did concede a recognition of belligerent status upon the Confederate military forces, 1861-1865, as in civil war generally, and the US Government consequently treated with the Confederate military authorities, including the subject of
Prisoner of war exchanges.
Civilian non-combatants arrested by US military authorities were sometimes sent to the military prisons for incarceration, and a large number were held at Camp Chase and many of the other military facilities in the North generally holding P.O.W.'s. For example, Lucious Desha of the Kentucky legislature was arrested and held at Camp Chase for several months in 1862-63 for his pro-Confederate sympathies.
During 1863 Congress passed an act requiring that civilian or political prisoners arrested by the authority of the President "otherwise than of prisoners of war" be referred to the civil courts for charges, etc. or released after a certain period of time...
In 1863, Judge Advocate Holt reported his understanding that the 1863 act had no particular bearing upon persons, even civilian, arrested for military rather than strictly political violations, or who were imprisoned upon the decisions of military tribunals...
By 1865 the Secretary of War stated he was having all such arrests investigated to see if they were subject to the March, 1863 act requiring release to the civil courts, etc.
