Unit history of 46th Quartermaster Regiment?

Dear Mr. Stewart-Winter,

Thank you for posting your request on History Hub!

We searched the World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office (Record Group 407) and located a history of the 46th Quartermaster Regiment for April 1942-January 1944. We also searched the National Archives Catalog and located a series titled Unit Histories, 1943 - 1967 in the Records of U.S. Army Operational, Tactical, and Support Organizations (World War II and Thereafter) (Record Group 338) that includes a file unit titled 46th Quartermaster Regiment: History. For access to and/or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at archives2reference@nara.gov.

We hope this information is helpful. Best of luck on your research!
