At 19:00 on 30 March, the Viet Minh 312th Division captured "Dominique" 1 and 2, making "Dominique" 3 the final outpost between the Viet Minh and the French general headquarters, as well as outflanking all positions east of the river. At this point, the French 4th Colonial Artillery Regiment entered the fight, setting its 105 mm howitzers to zero elevation and firing directly on the Viet Minh attackers, blasting huge holes in their ranks. Another group of French soldiers, near the airfield, opened fire on the Viet Minh with anti-aircraft machine guns, forcing the Viet Minh to retreat.
