To continue to highlight new digital series available on the National Archives Catalog, World War II War Diaries, Other Operational Records and Histories, 1942-1946 is another series that has come from NARA’s digital partners. This series includes some war diaries, some action reports, some submarine patrol reports and some battle histories of various naval, Marine, and other Allied commands during World War II. These records were scanned from a microfilm series that the Navy created from select war diaries and other reports.
This series is the first step in researching a Naval and some Marine operations during World War II, but remember this is not a comprehensive series of war diaries and so its title is a little misleading. If you cannot find a war diary or an operational report for the Naval command you are interested in the digitized war diary series, then please be aware that there are larger textual series of War Diaries, Action and Other Operational Reports, World War II Command Files in the Records of the Chief of Naval Operations (Record Group 38) and the U.S. Marine Corps Operations in World War II (a. k. a. Geographic Files) in the Records of the US Marine Corps (Record Group 127) where you might find what you are looking for.
One of the interesting tricks to the textual series of war diaries is that there are some command war diaries that have been stamped saying that a certain portion of the war diary has been microfilmed. Those microfilmed portions can be found in this series. As a follow-up to this statement, please do not assume that in all cases where one series ends the other begins. There are several cases where there is duplication and in others there are exclusively solitary copies of reports - meaning they exist solely in one series and not in the other.
The duplication of reports in multiple series or the isolation of unique reports in individual series can be said for action and other operational reports. Again If you cannot find a particular action report or Marine operational report, then you might try to look at the associated textual record series.
If you need to check for the availability of a war diary, action report, or another type of operational report, then please contact the National Archives at College Park - Textual Reference (RDT2) via email email@example.com, and RDT2 can check their holdings. If you are interested in getting a copy, then please provide your mailing address and phone number in your request in case RDT2 needs to draft a reproduction order form for you.
