The title "Veteran Reserve Corps" was substituted for that of "Invalid Corps" by General Order No. 111, dated March 18, 1864. The men serving in the Veteran Reserve Corps were organized into two battalions; the First Battalion including those whose disabilities were comparatively slight and who were still able to handle a musket and do some marching, also to perform guard or provost duty. The Second Battalion was made up of men whose disabilities were more serious, who had perhaps lost limbs or suffered some other grave injury. These latter were commonly employed as cooks, orderlies, nurses, or guards in public buildings.
