At dawn on February 17, 1979, more than 500,000 Chinese troops and thousands of tanks and vehicles entered Vietnam across the border and simultaneously attacked six northern provinces from Pa Nam Cum (Lai Chau) to Po Hen (Quang Ninh) on a length of 1,200 km.

The eastern wing had a forward headquarters located in Nanning (China) with Lang Son as the main target. Chinese troops moved in two directions, the first towards Dong Dang and the second towards Dong Khe and Cao Bang. They faced strong resistance from the Vietnamese army and people.

Determined to protect the country and its territorial integrity, the Vietnamese army and people fought back, bringing about the end of the war on March 18 the same year.
