On 5 January 1954 General Võ Nguyên Giáp ordered the Division's 57th Regiment to move from Phú Thọ to Điện Biên Phủ and after a 10-day, march, by 23–24 January they were in position in the south of the valley. 57th Regiment's main role during the Battle of Dien Bien Phu was to isolate the French garrison at Strongpoint Isabelle to the south of the main position in the valley. In late April following the heavy losses in the previous month's fighting, General Giáp ordered the Division's 9th Regiment to Điện Biên Phủ as reinforcements. Total estimated losses among the Division at Điện Biên Phủ are 490 killed.
