Dear Mr. Young,
Thank you for posting your request on History Hub!
Most of the finding aids to the records of the Office of Strategic Services (Record Group 226) are available in hard copy in the Textual Research Room at the National Archives at College Park, MD. However, there are some finding aids that can be viewed online. Therefore, we would suggest reviewing these finding aids at https://www.archives.gov/iwg/declassified-records/rg-226-oss. A full list of series located in RG 226 may be found at: https://www.archives.gov/research/military/ww2/oss/series.html.
Further, we searched the series titled “World War II Combat Operations Reports, 1941-1946” in the Records of the Army Air Forces (Record Group 18). We were unable to locate any records relating to your research.
We also searched the National Archives Catalog and located the series titled “Missing Air Crew Reports (MACRs), 1942-1947” in the Records of the Office of the Quartermaster General (Record Group 92) that includes Missing Air Crew Report number 6914 for the crew your father was part of. Please note that records in this series are digitized and may be viewed online.
The National Archives at College Park - Textual Reference (RDT2) has custody of microfilm copies of operational records relating to U.S. Army Air Force/U.S. Air Force units. We searched the Air Force History index to the microfilm and located 12 files that pertain to the 485th Bombardment Group . Please read the brief Abstract to determine which records you are interested in and click on the specific PDF icon. In the PDF listing, the IRISREF is the microfilm reel number and note the FRAME and FRAMELST numbers for the location on the reel. For the reel numbers beginning with A or B, please contact RDT2 via email at firstname.lastname@example.org for access to them. For the reel number that begins with K, the microfilm is still security classified and RDT2 will not be able to make the reel available to you. The original paper copy from which the film was created is still in the custody of the Air Force Historical Research Agency (AFHRA) and has been declassified. To obtain copies of these records, please follow the instructions on this page.
Please note that 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. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this information is helpful. Best of luck with your research!
