On 7 January 1947, its first regiment, the 102nd 'Capital' Regiment, was created for operations around Hanoi. Over the next two years, the first division, the 308th Division, later well known as the Pioneer Division, was formed from the 88th Tu Vu Regiment and the 102nd Capital Regiment. By late 1950 the 308th Division had a full three infantry regiments, when it was supplemented by the 36th Regiment. At that time, the 308th Division was also backed by the 11th Battalion that later became the main force of the 312th Division. In late 1951, after launching three campaigns against three French strongpoints in the Red River Delta, the PAVN refocused on building up its ground forces further, with five new divisions, each of 10–15,000 men, created: the 304th Glory Division at Thanh Hóa, the 312th Victory Division in Vinh Phuc, the 316th Bong Lau Division in the northwest border region, the 320th Delta Division in the north Red River Delta, the 325th Binh Tri Thien Division in Binh Tri Thien province. Also in 1951, the first artillery Division, the 351st Division was formed, and later, before Battle of Dien Bien Phu in 1954, for the first time in history, it was equipped with 24 captured 105mm US howitzers supplied by the Chinese People's Liberation Army. The first six divisions (308th, 304th, 312th, 316th, 320th, 325th) became known as the original PAVN 'Steel and Iron' divisions. In 1954, four of these divisions (the 308th, 304th, 312nd, 316th, supported by the 351st Division's captured US howitzers) defeated the French Union forces at the Battle of Dien Bien Phu, ending 83 years of French rule in Indochina.
