During the resistance war against the US invaders from 1954 – 1975, the North served as the country’s major rear base, providing comprehensive political, military, economic, and moral support for the southern battlefield. During the 1975 Spring General Offensive and Uprising, the North’s role became even more prominent, making a decisive contribution to the liberation of the South and national reunification.

Post-war economic recovery and reconstruction
After the 1954 Geneva Agreement, the North entered a period of post-war economic recovery and reconstruction, and socialist building. This was not only a national development task but also a solid foundation for the struggle to liberate the South.
For agriculture, irrigation systems were expanded, cultivated land increased, and food production gradually improved, ensuring supplies for both the home front and the battlefield. The establishment of agricultural cooperatives transitioned the economy from individual farming to collective production, aligning with the socialist model.
In industry, many factories and enterprises were restored or newly built to produce essential goods and materials for the resistance war. At the same time, attention was paid to upgrading transport infrastructure, bridges and roads, and storage facilities, facilitating logistics and support for the South.
Apart from promoting economic development, the North also focused on education, healthcare, and science and technology, improving the quality of human resources to serve both the resistance war and national reconstruction. Thanks to these efforts, by early 1975, the North had perfected its industrial and agricultural systems, ensuring maximum support for major military campaigns in the national struggle against the US invaders and for national liberation. Food, weapons, and military equipment were mobilised on an unprecedented scale, facilitating the Southern liberation army’s rapid, powerful, and decisive offensive during the spring 1975 campaign.

Comprehensive support for southern battlefield
During the resistance against the American imperialists (1954–1975), the North implemented a comprehensive support strategy for the South, mobilising both human and material resources to ensure the ultimate victory.

In terms of manpower, millions of young people enlisted to reinforce the forces for the Southern front. Recruitment campaigns were not only carried out in accordance with annual plans but also intensified during crucial moments of the resistance war. Especially as the struggle entered its decisive phase, the North committed all available forces to strengthen the South’s fighting power.
In terms of material resources, the North dedicated all of its efforts to supplying the Southern battlefield with massive amounts of materials, including food, weapons, ammunition, medicines, and military equipment. The production systems – from defence factories to agricultural cooperatives – were fully mobilised to meet the fight’s demands.
Especially, since early 1975, the North fully mobilised thousands of tonnes of food, weapons, and military supplies in preparation for key campaigns. Strategic transport systems were expanded to ensure continuous supply to the southern liberation forces. Trains and trucks worked day and night to transport necessities to the battlefield, while the “no-number ships”, defying the enemy’s tight blockade, secretly transported thousands of tonnes of weapons and military supplies to the South.

To ensure a continuous flow of support from the North to the South, the crucial roles of two strategic transport routes – the Ho Chi Minh trails on land and at sea – must be highlighted. The Ho Chi Minh Trail on land was continuously expanded and upgraded, forming a vital transport network across the Truong Son mountain range. Despite bombs and the enemy’s fierce blockade, millions of tonnes of weapons and food, and hundreds of thousands of soldiers and young volunteers marched through this route. Additionally, to avoid the tight control of the US over land routes, a strategic sea transport route was established, using ships to carry weapons and supplies to the South. This sea route not only supported key battlefields in the South but also demonstrated the ingenuity, intelligence and creativity of the Vietnamese army and people in the resistance war.
Resolutely resisting US destruction campaigns
Recognising the strategic importance of the North, the US conducted two destruction campaigns in the North with the aim of cutting off support to the South. However, the Vietnamese military and people remained resilient, firmly defending the northern rear base while maintaining and strengthening the nation’s war-fighting capabilities.
The first destruction campaign (1965–1968): In 1965, the US made its first airstrike “Operation Rolling Thunder” against Northern Vietnam. Transport routes, factories, and warehouses were heavily bombed, yet the northern people remained resilient and stood their ground. The “Producing while fighting” movement developed strongly and gained momentum, and transport routes were urgently repaired under the slogan “The enemy destroys, we repair and move forward.” The air defence – air force, including the militia, shot down hundreds of American aircraft, foiling US efforts to cut off supplies from the North for the South. In 1968, after suffering heavy losses, the US was forced to halt its bombing campaign in the North. This victory paved the way for the General Offensive and Uprising in Spring 1968, which significantly altered the course of the war.
The second destruction strike (April – December, 1972): In an attempt to support the Saigon puppet regime amid the growing momentum of northern forces in the South, the US launched its second destructive airstrike “Operation Linebacker II” from December 18–30, 1972, aiming to bomb Hanoi, Hai Phong, and other key areas in order to put pressure on Vietnam in the negotiation round of the Paris Peace Accords.

However, with a solid air defence strategy, the northern military and people responded fiercely. During the “Dien Bien Phu in the Air” campaign, the northern air defence forces shot down 81 American aircraft, including 34 B-52 bombers, causing unprecedented losses for the US. The victory in the “Dien Bien Phu in the Air” campaign put immense pressure on the US, forcing it to sign the Paris Peace Accords in 1973, ending the war and withdrawing its troops from Vietnam.
With unwavering determination, solidarity, and great contributions in both manpower and resources, the North not only withstood two US bombing campaigns but also provided great assistance to the southern battlefield, playing a vital role in the great victory of Spring 1975.
This triumph was not only the result of courage and determination but also a powerful testament to the collective strength of the entire nation in the struggle for national independence and reunification./.
