Dear Ms. Drummond,
Thank you for posting your request on History Hub!
According to The Last Offensive (1973) that is available online from the US Army Center of Military History, the 4th Armored Division, 10th Armored Infantry Battalion and 37th Tank Battalion were involved in Task Force Baum (or the Hammelburg Mission) to rescue American prisoners of war from OFLAG XIII-B.
We searched the National Archives Catalog and located the series 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 one file for the 37th Medium Tank Battalion in the 1940s and 110 files related to the 4th Armored Division in the 1940s that may contain some information related to your research. The series World War II Operations Reports, 1940-1948 in the Records of the Adjutant General's Office, 1917-1985 (Record Group 407) may also include records of these units during WWII. Please note that these records typically do not include records about individual soldiers but they provide information about the orders, actions, and engagements of a unit as a whole. For more information about these non-digitized records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at email@example.com. Please include as much information as possible (e.g. specific unit numbers, dates, names of individuals) in your inquiry.
We also located the series War Crimes Committed Against American Prisoners of War Index to the Series "Case Files, 1944-1949" in the Records of the Office of the Judge Advocate General (Army) (Record Group 153) that includes 4 references to "OFLAG 13 B" and 2 references to "OFLAG XIII B" that might be of interest to you. The series European Name Index to the Series "Case Files, 1944-1949" in Record Group 153 contains 53 references to "OFLAG XIII B" and 33 references to "OFLAG 13 B", as well. These indexes have been digitized and may be viewed online using the Catalog. Plus, we located the series Stalag Name Index to the Series "Case Files, 1944-1949" in Record Group 153 that includes information about prisoners held at OFLAG camps, too. These three indexes relate to several series, including the series Case Files, 1944-1949 in Record 153 that may contain more relevant information. These records have not been digitized. In addition, we located the series Persons and Places Dossier Files in Record Group 153 that includes the file 100-526 - OFLAG XIII-B (Hammelburg, Germany - American POWs Killed). Please contact RDT2 for assistance with these and similar records.
Next, we located the series Index to Personalities in the U.S. Army Signal Corps Photographic Files in the Records of the Office of the Chief Signal Officer (Record Group 111) that includes 10 references to Hammelburg that may be of interest. This index has been digitized and may be viewed online using the Catalog. For access to and information about the images it relates to, please contact the National Archives at College Park - Still Pictures (RDSS) at firstname.lastname@example.org.
If you have not already done so, we suggest that you request a copy of your relative’s Official Military Personnel File (OMPF). OMPFs and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and before 1959 and for officers of the U.S. Army who were separated from the service after June 1917 and before 1959 are in the custody of NARA's National Personnel Records Center (NPRC) in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. Veterans and their next of kin also may use eVetRecs to request records. See eVetRecs Help for instructions. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
We searched the Access to Archival Databases (AAD) and located the Records of World War II Prisoners of War, 12/7/1941 - 11/19/1946 in the Records of the Office of the Provost Marshal General (Record Group 389) and the World War II Army Enlistment Records database that may include files for your relative. If you locate a record for him, you may use this information when submitting a request for his OMPF.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2 and RDSS. Also, NPRC will continue servicing requests ONLY associated with medical treatments, burials, homeless veterans seeking admittance to a homeless shelter, and those involving the VA Home Loan program. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
Thanks! That’s a lot more information than I expected.
