@saab,
I have a journal kept by a wounded Union prisoner who was detained in Libby Prison and was released when the prison was moved to Andersonville (due to reasons not discussed by the prisoner). Its a heart rending day by day account of being an attendent to prisoners , who, alive one day, and then dead the next were known to the prisoner who was junior artllery officer..
He addressed his journal to a "Mary" who wold be given the journal on the event of his death . As the news of the war gradually turned away from the Confederacy , and the raid on Richmond had speeded up the completion of the more notorios Andersonville, His spirit improved and he apparently spent time keeping spirits high among his other officers. (Libby prison, according to the journal, was mostly officers and "spies").
The journal is written in fantastic penmanship and some left over "Elizabethan " spelling of words.
The flourishes and obvios calligraphgic thickenings of lines are amazing. I dont know what kind of ink he used , but its brownish rather than black or blue, so I dont think he made it from berries.,
