The Confederate States, however, could send to the war a far greater proportion of their military population than the Northern States, as they possessed a large agricultural population of blacks who were exempt from military service. The aggregate enrollment of the Confederate Armies during the whole war, according to their best authorities, numbered over 600,000 effective men; of whom not over 400,000 were enrolled at any time. These eleven States furnished, also, 86,009 men to the Union Armies, receiving in return over 19,000 men from the Border.
Many will hold, and with good reasons, that 600,000 is too low an estimate for the total number that served in the Confederate Armies. Their military population and sweeping conscription acts indicate more. The number of regiments which served continuously during the war indicate more.
A compilation made from the official rosters of the Confederate Armies as they stood at various battles, and at various dates covering the entire period of the war, shows that the different States kept the following number of regimental organizations in almost continuous service in the field:

ALABAMA -- 55 regiments, and 11 battalions of infantry; 5 regiments of cavalry; 3 regiments of partisan rangers; and 16 batteries of light artillery.

ARKANSAS--35 regiments, and 12 battalions of infantry; 6 regiments, and 2 battalions of cavalry; and 15 batteries of light artillery.

FLORIDA--10 regiments, and 2 battalions of infantry; 2 regiments, and 1 battalion of cavalry; and 6 batteries of light artillery.

GEORGIA--68 regiments, and 17 battalions of infantry; 11 regiments, and 2 battalions of cavalry; 1 regiment, and 1 battalion of partisan rangers; 2 battalions of heavy artillery; and 28 batteries of light artillery.

LOUISIANA--34 regiments, and 10 battalions of infantry; 2 regiments, and 1 battalion of cavalry; 1 regiment of partisan rangers; 2 regiments of heavy artillery; and 26 batteries of light artillery.

MISSISSIPPI-- 49 regiments, and 6 battalions of infantry; 7 regiments, and 4 battalions of cavalry; 2 regiments of partisan rangers; and 20 batteries of light artillery.

NORTH CAROLINA-- 69 regiments, and 4 battalions of infantry; 1 regiment, and 5 battalions of cavalry; 2 battalions of heavy artillery; and 9 batteries of light artillery.

SOUTH CAROLINA-- 33 regiments, and 2 battalions of infantry; 7 regiments and 1 battalion of cavalry; 1 regiment, and 1 battalion of heavy artillery; and 28 batteries of light artillery.

TENNESSEE--61 regiments, and 2 battalions of infantry; 21 regiments, and 11 battalions of cavalry; 1 regiment, and 1 battalion of heavy artillery; and 32 batteries of light artillery.

BORDER STATES-- 21 regiments, and 4 battalions of infantry; 9 regiments, and 5 battalions of cavalry; and 11 batteries of light artillery.

C. S. REGULARS-- 7 regiments of infantry; 6 regiments of cavalry; and one battery of light artillery.

AGGREGATE--529 regiments, and 85 battalions of infantry; 127 regiments and 47 battalions of cavalry; 8 regiments and 1 battalion of partisan rangers 5 regiments and 6 battalions of heavy artillery; and 261 batteries of light artillery. In all, equivalent to 764: regiments of 10 companies each.

These were all troops of the line, and they served during the whole, or the greater part of the war. The number does not include regiments which served a short time only; neither does it include disbanded or consolidated regiments; nor State militia, Junior Reserves, Senior Reserves, Home Guards, Local Defense regiments, and separate companies.
