Fredrick Kronenberger (2nd New Jersey - 6th Corps) 1864 Letters?

[Moonshine]

After reading some of the Frassanito book "Grant vs. Lee" I looked to see if some of the letters Frederick Kronenberger wrote was available and all I can find is just basic information. I can't seem to find any of the letters themselves.

Does anyone have a link or access to these letters written between he, his family, friends and with the assistance of Miss Robison?

Thanks for any help, assistance or direction.
