Dear Mr. Tillery,
Thank you for posting your request to History Hub!
We searched the WWII Operations Reports in the Records of the Adjutant General's Office, 1905-1981 (Record Group 407) and located a history of the 23rd Headquarters Special Troops for July 1944 to March 1945. It consists of approximately 150 pages and the file number is SPHQ-23-0.1. To order a copy of this file, please contact the National Archives at College Park - Textual Reference via email at firstname.lastname@example.org.
We hope this information is helpful. Best of luck with your research!
