Good job as usual Hugh, most interesting story. There was and is a large collection of letters from Camp Chase. However the letters were the by product of a failed Confederate spy misson by Mrs. Charlotte (Lottie Moon) Clark. The letters in question were dated in April of 1862 just prior to the opening of Johnson's Island and the transfer of some of the junior officers from Chase to that location. The bag of letters were found in the Statehouse in 1906 long after the War, after Mrs. Clark's true purpose for visiting Camp Chase had been established. The letters were then donated to a historical society in Virginia in 1948 where they are housed to this day. The gentleman who donated the letters was murdered a few years later in Cleveland, Ohio and the case has NOT been completely closed. As for Mrs. Clark, she would go on and become a famous Confederate spy with her sister Virginia. At least one if NOT both of them had early acting careers in Califorina at the turn of the century.

Aside from the hundreds of Camp Chase letters found on the internet and E-bay from time to time, there is as far as I know of any large collection of Camp Chase letters
