Confederate end of war paroles are reported as if soldiers were captured at one point and released later. No 'captures' or prisoner-of-war camps were involved. Here's what really happened.

General Jones surrendered all troops under his command in the Department of South Georgia and Florida to General Edward M McCook. Serving under his command, Middleton's cavalry battalion was included in the agreement Jones signed at Tallahassee FL, May 10, 1865. Whether they knew it or not, soldiers had been officially surrendered.

Next step: notifiy all Confederate soldiers in this department.
Troops surrendered were notified as soon as possible. Officers then assembled their men to receive paroles at the nearest U S military post. For example, many soldiers came to Albany GA to be paroled. A soldier identified himself, his rank and command to U S authorities. A clerk prepared a parole, usually on a printed form. The soldier signed his parole, received an official copy, and went home. U S authorities kept a list of paroled men for future reference. A parole was a promise of loyalty and good behavior under penalty of law. If a former Confederate was arrested in violation of parole or did not have a parole, he could be arrested and jailed. He could then be tried and punished, possibly by hanging.
