Dear Mr. Gibson,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the World War II Combat Operations Reports, 1941-1946 in the Records of the Army Air Forces (Record Group 18) that includes 26 mission reports related to the 100th Bomb Group for 1945 only. For more information about these non-digitized records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org. We were unable to locate specific records of the 350th Bomb Squadron. Records of lower echelon units sometimes were incorporated into the files of the Bomb Group.
Also, RDT2 has custody of microfilm copies of operational records relating to U.S. Army Air Force units. We searched the Air Force History index to the microfilm and located 85 files related to the 100th Bomb Group from February-August 1944, including 2 files related to Thorpe Abbots that may be of interest to you. Plus, we located one file with squadron histories. 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. Since the reel numbers begin with A or B, please contact RDT2 via email at email@example.com for more information about them.
Next, we located the series Black and White and Color Photographs of US Air Force and Predecessor Agencies Activities, Facilities and Personnel - World War II and Korean War in the Records of U.S. Air Force Commands, Activities, and Organizations (Record Group 342) that contains 30 images related to the 100th Bomb Group. These photographs have been digitized and may be viewed online using the Catalog.
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.
Finally, we searched online and located Air Force Combat Units of WWII and Combat Squadrons of the Air Force WWII that provide listings of US Army Air Force units with information about the types of aircraft assigned in given years, and the campaigns in which they participated.
We hope this is helpful. Best of luck with your family research!
Awesome! Thank you very much for this information. I'm going through it all now. Cheers!
