"The 1st Arkansas Light Artillery was merged with Green's Kentucky Battery, Co. B, 2nd Alabama Light Artillery Battalion and Cobb's Kentucky Battery in January, 1864. The Battery was surrendered by Lieutenant General Richard Taylor, Commanding the Department of Alabama, Mississippi, and East Louisiana, at Citronelle, Alabama on May 4, 1865.

Not sure why. Did the battery suffer heavy casualties during the Siege of Chattanoga?
