Can anyone help me? US 40th Tented General Field Hospital

Hello, I've started a separate thread for the 40th General Hospital on this forum (40th General Hospital - ETO). I recently obtained several photos and documents pertaining to my grandfather’s (Conan J. Peisen, MD) service as a medical officer at the 40th GH that I will share here and post to my Facebook group (https://www.facebook.com/groups/40thGH/) dedicated to the 40th GH that I created as a way to be in touch with relatives of men and women who served with the 40th GH. My goal is to document the unit history of the 40th GH and I am in touch with the U.S. National Archives to obtain copies of records and other documents that I will share after I receive them.
