"The Confederate States never had in their defense more than 200,000 men in the field at one time. Third—From 1861 to 1865 the Confederate forces actively engaged were only 600,000."

600,000.
I've seen that estimate before but it can't be right. On April 30, 1863, the army had almost 500,000 on the rolls. How many died or were discharged prior to that date?...and how many joined after that date? Both of those numbers would have to be added to the 500,000.

"These facts are taken from calculations, made with great care by Dr. Joseph Jones, submitted to arid approved by General S. Cooper, Adjutant-General of the Confederate army."

I sort of doubt that Samuel Cooper approved the calculations since he was adjutant and inspector general for most of the war.
