Formerly Sheriff of Decatur County, Capt. John T. Wimberly made it to Virginia, but not the way you might guess. He was captured near Sunbury in Liberty County GA on Dec. 13, 1864, and taken to Old Capitol Prison in Washington DC. He may have seen the Virginia shore while aboard a prison ship in the Potomac River, taking the oath of allegiance at Fort Delaware, June 10, 1865.

Here's a map of Liberty County made in 1864 --

The report of Col O L Baldwin, 5th Kentucky Cavalry (U.S.), mentions pursuit Confederates belonging to Co B, 29th Georgia Cavalry Battn. His advance encountered pickets at Midway, and pressed forward through Dorchester to Sunbury, capturing 17 officers and men.

On July 1, 1864, five companies of the battalion had been ordered to report to General McLaws, commander of the defenses of Savannah. Hood's men were assigned to picket the coastline between St. Marys and the Ogechee River. Two companies remained in Florida. Lt Col Hood reported 300 officers and men, plus three South Carolina companies amounting to 134 troopers. At one point Capt Wimberly served as battalion commander.

The company reported from nearby Madison FL on Apr 26 and May 19, 1864. Officers and men drew rations from a QM depot at Madison, reporting 59 horses on June 24th, 1864. The eastern camp of the company was located at Station #3 on the railroad, June 4, 1864. At that time the company included 54 horses and four mules. The battalion's mission was to picket the coastal region and operate in disloyal neighborhoods. During this period Capt Wimberly reported to Brig. Gen. W. M. Gardner.

The company organized by election of officers at Bainbridge on Sept 23, 1863. 1st Lt Samuel E Conyers, age 38, came from Co E, 2nd Florida Cavalry, also known as the Beauregard Rangers. 2nd Lt James H, Campbell came from Co B, 2nd Georgia Battn, and had been wounded in Virginia. 2nd Lt Jacob Harrell, also came from Co K, 2nd Georgia Cavalry, Wimberly's old company. The company remainded at Bainbridge during 1863, receiving cavalry sabers, canteens, saddles, halters and bridles, along with other camp equipment. These items were issued by the QM depot at Quincy FL, Sept 30 and Oct 14, 1863. Lt Conyers drew rations for 41 horses in Nov 1863.

John T. Wimberly originally entered Confederate service as 2nd Lt of Co K, 2nd Georgia Cavalry Regt. He enlisted at Bainbridge on Mar 10, 1862, age 30, value of horse stated as $275. Incidentally 3rd Cpl Christopher C Wimberly, age 19, enrolled with John T Wimberly, value of horse stated as $235.

Hopefully this provides some detail on Capt Wimberly and his company. In 1870 he and his family are reported as residents of Harrell, a community between Cairo and Bainbridge.
