George, I was only going by what I had saw on his Compiled Military Service Records as Columbus which are not always accurate and it does make more sense that he would have enlisted in Columbia, Mississippi.
Camp Chase had three separate prisons numbering 1, 2 and 3. Prison number 1 was the smallest and for the 1st half of the war was generally used to house political prisoners. Toward the latter part of the war some Confederate Officers were housed there. That is the reason why I believe James A. Pitman was either in Prison number 2 or 3. Prison number two was the larger of the 3 prisons at Camp Chase.
Prison number 2 and 3 were together but separated by a large petition thus preventing prisoners from talking to each other.
Each prison had their own hospital. It appears that of April 1862 the Confederates looked after their own sick and wounded in each hospital but I would guess they had a Union doctor overlooking the hospital. When a seriously ill or wounded prisoner at one of the hospitals they appear sometimes to be taken to the Camp Chase General Hospital. Of course prisoners with small-pox were taken to the Pest House at Camp Chase located not too far from what is now the Camp Chase Cemetery about 1/3 of a mile from the prisons.
In my opinion the Union doctors did everything possible to save a Confederate life while Union authorities did not. The treatment of Confederate prisoners came down from Hoffman and Secretary of War Stanton and carried out by various prison commanders.
Andersonville verses Camp Chase insofar as small-pox. Andersonville stated 67 Union POW's died there of small-pox for about 1/2 of 1%
While at Camp Chase 372 Confederates died of small-pox for about 17.15%
The following is only my opinion and should not be taken for fact. Doctor White at Andersonville took prisoners who had small-pox and put them all into a separate holding area about three miles away.
The doctors at Camp Chase took their small-pox prisoners to a Pest House about 1/3 of a mile away.
Although each side could vaccinate their prisoners for small-pox neither side did not know what caused small-pox.
It is my opinion that whenever a Confederate at Camp Chase went to the pest house his blanket was given to a new Confederate prisoner thus infecting them with small-pox.
At Andersonville the Confederate authorities did not have blankets to give to their prisoners.
At any rate the Confederates faired much better with small-pox prisoners than the Union did and all this with the blockade in effect and a lack of medical supplies.
As for James A. Pittman somewhere I'm sure there is mention of him of being in prison number 2 or 3 probably on ancestry. But many of the names are faded and I only looked for James A. Pittman and J. A. Pittman. He could have been listed in other ways such as J. Pittman etc. and his name may have also been misspelled. When I get back to the Camp Chase prisons again I'll keep an eye out for him and if I find him I'll let you know.
