Final attacks The Viet Minh launched a massed assault against the exhausted defenders on the night of 1 May, overrunning Eliane 1, Dominique 3, and Huguette 5, although the French managed to beat back attacks on Eliane 2. On 6 May, the Viet Minh launched another massed attack against Eliane 2, using, for the first time, Katyusha rockets. The French artillery fired a "TOT" (time on target) mission, so that artillery rounds fired from different positions would strike on target at the same time.Davidson, p. 261 This barrage defeated the first assault wave, but later that night the Viet Minh detonated a mine under Eliane 2, with devastating effect. The Viet Minh attacked again, and within a few hours the defenders were overrun.
