This series of World War I Military Intelligence records is mainly comprised of attache reports. The scope and content of the intelligence materials contained within the reports is vast; however, the greater part of the material bears on military conditions and the military might and preparedness of European nations both allied and unfriendly. Some intelligence data also exists for the countries of the Far East and Latin America.

The information contained in the attache reports was derived from various sourced: U.S., British, French and Italian Naval Attaches, German deserters, and British Admiralty reports to name a few. Much of the information was supplied by nameless individuals who were merely identified by a letter symbol.

The attache reports are found in two forms: the original copies of the reports and bimonthly compilations of the derived intelligence data. The reports, despited the form and organization they assume, generally contain the same type of information and are arranged chronologically. There is a card catalog index to these records in four file drawers. The cards are filed alphabetically by subject with references to volume and page numbers. This card catalog is available and assessible only onsite at the Naval Historical Collection.
