I was captured on the 13th of July, heavily ironed with log chain and ball, transported to this prison, thrown into a cell 6 X 3 feet with my iron fetters on, kicked, cuffed, taunted, jeered and maltreated in every conceivable form. I remained the inmate of this living tomb until my life was despaired of. I was then removed to the hospital where I have remained ever since, denied the priviledge of a common culprit, denied a parole, denied exchange; I have had to run the gauntlet of every disease which human flesh is heir to--smallpox, measles, mumps, pneumonia; in a word, all the ills of Pandora. Oh! The horrors of this place, the cruelty of my prosecutors, tongue cannot tell, neither hath it entered into the hearts of man to conceive. I have seen hundreds of my companions in arms consigned to a premature and untimely grave here by the cruelty and injustice of my enemies, murdered in cold blood in this terrible house of disease and death."

if any one has any additional info on Capt Melton, I would indeed be in your debt.
