Dear Mr. Stevenson,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Logbooks of U.S. Navy Ships and Stations, 1941 - 1983 in the Records of the Bureau of Naval Personnel (Record Group 24) that include the deck log Agerholm (DD-826) - May, 1966. This deck log has been digitized and can be viewed online through the Catalog. Please note that the Catalog does not always list logs in chronological order. When viewing logs for each month, you may wish to click on the red PDF icon under the “Documents” heading. This will allow you to view the entire month’s logs as a single file. Once you have done so, you may use the blue download button to download the PDF. Due to the size of the files involved, it may take a little while for them to load in full. Please be patient. If you have any problems accessing these files, please email Catalog@nara.gov.
We also suggest reviewing the blog Update on Availability of Vietnam Era (1956-1978) US Navy Deck Logs, which includes instructions on how to find deck logs in the National Archives Catalog as well as information on how to request information about logs not yet in the Catalog.
We hope this is helpful. Best of luck with your research!
Jason, this is what I need. Many, many thanks.
