Seeking information on WWII Aleutian's code breakers

Dear Ms. Martin,

Thank you for posting your request on History Hub!

We searched the National Archives Catalog and located a series titled Summaries of Radio Intelligence Japanese Naval Attache Messages in the Records of the National Security Agency/Central Security Service (Record Group 457) that includes the work of the Aleutian Task Force. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at archives2reference@nara.gov.

We also located a pamphlet by the U.S. Army Center of Military History on the Aleutian Islands that may be of interest plus the Navy role in the Aleutians.

We hope this information is helpful. Best of luck with your research!
