Dear Mr. Wulfkuhle,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Records of Ground Combat Units, Support Units and Other Commands, 1939-1950 in the Records of the U.S. Marine Corps (Record Group 127) that consists of war diaries, readiness reports, station lists, unit histories, action reports, operational plans and orders, and related documentation gathered by the Historical Division for various Marine Corps units, mostly during WWII. For example, the series includes 14 files related to the 1st Provisional Marine Brigade that was one of the first Marine units to serve in Europe. We also located the series Records Relating to United States Marine Corps Operations in World War II, 1939-1949 in Record Group 127 that consists of records documenting the principal amphibious assaults and ground combat operations of the Marine Corps during the World War II era, as well as occupation of formerly enemy-controlled areas. These records have not been digitized. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org. Please include as much information as possible in your inquiry, such as specific engagements, unit numbers, and dates of interest.
Next, we located the series Muster Rolls of US Navy Ships, Stations, and Other Naval Activities, 1/1/1939-1/1/1949 in the Records of the Bureau of Naval Personnel (Record Group 24) that contains 5 files related to the 1st Provisional Marine Brigade. These files have been digitized and may be viewed online using the Catalog, and you also may search within the series for records related to other relevant Marine units. In addition, the series Logbooks of U.S. Navy Ships and Stations, 1941-1983 may contain deck logs of ships that were assigned Marine detachments, and the series World War II War Diaries, Other Operational Records and Histories, ca. 1/1/1942 - ca. 6/1/1946 in the Records of the Office of the Chief of Naval Operations (Record Group 38) contains war diaries and reports concerning the activities of ships during World War II, including 52 files related to the USS Philadelphia. Many of these records have been digitized and may be viewed online using the Catalog. Please contact RDT2 with questions about the non-digitized records.
Plus, we located 8 files related to the Marine Corps in various series in the Records of the Office of Strategic Services (OSS) (Record Group 226) that may be of interest to you as some members of the Marine Corps worked as intelligence officers with the OSS in Europe during World War II. Some of these records have been digitized and may be viewed online using the Catalog. Please contact RDT2 for assistance with the non-digitized records.
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.
Further, we located the National Park Service online publication A Different War: Marines in Europe and North Africa (Assignment to London), and we located information about the OSS Maritime Unit on the U.S. Special Operations Command (USASOC) website.
Finally, we located a Brief History of Marines in the Atlantic, Europe, and Africa during World War II on the website of the U.S. Marine Corps History Division. We suggest that you contact them directly for additional assistance.
We hope this is helpful. Best of luck with your research!
