How many men were in Confederate Army?

Because of poor record-keeping, there is no accurate number that represents the strength of the Confederate States Army. Estimates range from 500,000 to 2,000,000 men who were involved at any time during the war. Reports from the War Department began at the end of 1861 (326,768 men), 1862 (449,439), 1863 (464,646), 1864 (400,787), and "last reports" (358,692). Estimates of enlistments throughout the war were 1,227,890 to 1,406,180.[2]
