1918: "Allegheny" Field Code was issued.

12 August 1918: The "Allegheny" field code was issued. Learn about American Army Field Codes in a document by William Friedman via the link at the bottom of the page.

Trench codes were codes used for secrecy by field armies in World War I. A reasonably-designed code is generally more difficult to crack than a classical cipher, but of course suffers from the difficulty of preparing, distributing, and protecting codebooks. The Americans adopted a series of codes named after rivers, beginning with "Potomac". They learned to print the codebooks on paper that burned easily and degraded quickly after a few weeks, when the codes would presumably be obsolete, while using a font that was easy to read under trench conditions.

  • Maj. Albert J. Myer, founder of the "wig-wag," or aerial telegraphy, flag signaling system, was appointed first chief of the U.S. Army Signal Corps. Myer's flag "wig-wag" code was first used in the first Battle of Bull Run or Battle of First Manassas. The code was used extensively by both the Union and Confederate armies throughout the war.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
