In the resistance war against American imperialists, Cipher Station A69 was tasked to ensure smooth information and communications for Lao, Cambodian and Vietnamese units operating in various theaters in South Vietnam, Laos and Cambodia. 

At the inaugural ceremony of the memorial house

With the slogan “Communication secured till the last breath,” troops of the cipher station braved all difficulties and hardships, even sacrificed their own lives to ensure timely, precise, secret and safe transmission of military information in any circumstances.

On July 2, 1972, US troops launched a large-scale air-strike on the station, causing huge losses and claiming lives of 13 troops and leaving many injured.

On May 7, 2009, Len Ha cave where 13 troops of Cipher Station A69 laid down their lives was recognized as a national relic site by the Ministry of Culture, Sports and Tourism.

To honor and pay gratitude to the 13 sacrificed troops, the Signal Corps built and upgraded various facilities in the relic site.

Last year, the Quang Binh Provincial People’s Committee approved a detailed master plan to build an over-12ha relic site with various important and meaningful facilities, including the memorial house - a culturally and spiritually significant place where domestic and international visitors, especially troops, could pay tribute to the fallen soldiers and learn more about the revolutionary tradition of the nation.

The house was put into operation after nine months of construction with high quality and good architecture.
