14 March 1951: Seoul, South Korea, recaptured by UN forces.

Excerpt from Wikipedia: Operation Ripper, also known as the Fourth Battle of Seoul, was a United Nations military operation conceived by the commander US Eighth Army, General Matthew Ridgway, during the Korean War. Operation Ripper was preceded by the largest artillery bombardment of the Korean War. On the middle, the U.S. 25th Infantry Division quickly crossed the Han and established a bridgehead. Further to the east, IX Corps reached its first phase line on 11 March. Three days later the advance proceeded to the next phase line. During the night of March 14–15, elements of the South Korean 1st Infantry Division and the US 3rd Infantry Division liberated Seoul, marking the fourth and last time the capital would have changed hands since June 1950. The Communist forces were compelled to abandon it when the UN approach to the east of the city threatened them with encirclement.

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.
