On November 19, 1864, General E. Kirby Smith, commanding the Confederate Trans-Mississippi Department, issued Special Orders No. 290, organizing the artillery of the department into battalions. The component
batteries rarely, if ever, operated together. They were usually assigned individually to an infantry or cavalry brigade to provide fire support. Following is the organization of the artillery:
