1944: Jargon Code Message Announced D-Day Invasion

On 1 June 1944, perhaps the most famous jargon code message announced the impending D-Day invasion. It was intercepted and recognized by the German 15th Army, but was ignored at higher headquarters.

The message read, "Les sanglots longs des violons de l'automne."

"Chanson d'automne" ("Autumn Song") is a poem by Paul Verlaine, one of the best known in the French language. It is included in Verlaine's first collection, Poèmes saturniens (1866).

The first and second lines of the poem (Les sanglots longs des violons de l'automne blessent mon coeur D'une langueur Monotone) were broadcast by the Allies in 1944 as a code message to the French Resistance in preparation for D-Day. When the second line was broadcast over the radio waves, it signaled that the invasion was to come in 24 hours.

  • Birthday of cryptologic machine designer Edward Hebern. Hebern's five-rotor cipher machine is cryptologically significant as part of the overall evolution in U.S. manufactured rotor devices. The National Cryptologic Museum has two very rare five-rotor Hebern cipher machines in its collection.

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.
