His name was associated with the Battle of Dong Khe during the Autumn-Winter Border Campaign of 1950. Assigned to carry an explosive charge to destroy an enemy bunker and open the way for his unit, he suffered catastrophic injuries when enemy fire shattered his right arm.
Determined to continue fighting despite his severe wounds, he asked a fellow soldier to amputate his mangled arm and used his remaining arm to carry the explosives forward and destroy the bunker, enabling his unit to advance and secure victory. His actions became an enduring symbol of courage, determination, and revolutionary heroism in Vietnam.
In recognition of his exceptional service, in 1952 La Van Cau was among the first soldiers nationwide to receive the title of People's Armed Forces Hero.
After the war, despite his physical trauma, Cau continued serving in the military in roles related to political education, youth affairs, and personnel management and rose to the rank of Colonel before retiring in 1996.
