My gggrandfather Pvt. Calvin Davis, age 18, was captured on May 25, 1864, near Dallas, Ga., sent to Rock Island for the duration of the war. (I spent a week in the Quad Cities on business a few years ago, and everyone I encountered had no idea thare had been a prison there.)
My gggrandfather, 2Lt Lewis Washington Myers (the one I had so much trouble finding out about), was captured at Manchester in Middle Tennessee on the morning of June 27, 1863, by Col. John T. Wilder's mounted infantry brigrade. He was sent to Johnson Island in Sandusky Bay, Lake Erie, and was released at City Point, Virginia in January 1865 as part of the mutual releases that resulted from pressure on the Lincoln Administration from reports of conditions at Andersonville, at least that's what I've read.
Davis's son and Myers' daughter were my grandparents. Both thir came from around Chickamauga and Rock Springs in NW Ga. The first map produced of the Chickamauga National Military Park shows the Myers home on it, just north of the town.
My grandparents eventually moved to Chattanooga and lived on the east slope of Missionary Ridge about 1/4 mile from the Ohio monumnet. My mother attended the school that stood on the site of Bragg's HQ on the ridge.
(Hope this is not TMI)
