During the ceremony, the delegates recalled the history and traditions of Division 391. Fifty years ago, on March 15, 1975, Division 341B was established in Yen Thanh commune, Yen Mo district, the northern province of Ninh Binh, consisting of three regiments, four battalions, and subordinate companies. Immediately after its establishment, Division 341B participated in the campaigns to liberate Khanh Hoa and Ba Ria - Vung Tau provinces in the South. It then continued to serve as a strategic reserve force for the 1975 Spring Offensive and Uprising. Following the complete liberation of the South, the division was reassigned to the General Department of Economic Construction with the mission of restoring the North-South Railway’s section in the central province of Quang Binh.

In 1977, the division was renamed Division 391 and became part of Corps 12. It undertook many important missions, such as ensuring border security in the North, opening transportation routes in neighbouring Laos and the provinces of Son La and Dien Bien, and building National Road 279. After successfully completing these tasks, the division reduced its personnel and became Brigade 391, which was officially disbanded in 1990.
