list the following two fellows as contacts (experts?) on the 52nd. They may be able to assist in your quest. Hopefully their email addresses are current.
I also copy the unit bibliography found at the US Army History Military Institute, Carlisle Barracks.
It would be a great find if you could locate a soldiers diary, the Vicksburg Military Battlefield Park would be one place to look.
