Good post. As an example, during his Tennessee campaign in the winter of 1864/65, Hood had three infantry corps. The Order of Battle lists about 190 individual regimental numbers. This is very deceiving as 91 of these regiments were so depleted that combining several together became necessary to form effective combat units. These 91 regiments were formed into 36 "large" regiments, with 2 to 4 regiments in each "large" regiment. Still, the large number of regiments hide the truly depleted nature of Hood's army as he had no more than about 27,000 total infantry for the campaign, an seriously weak average of 9000 per corps. Manpower had become a huge problem for the Confederacy this late in the war. -- Al
