Sassi's objective was "to allow a kind of breakthrough with the help of the French Union troops based at Éliane hill in order to surround the coolies supplying the Viet Minh combatants" and "to suddenly attack these weak enemies with the benefit of surprise". Achieved, this operation would have brought a great confusion among the enemy line.[1][2]
Like their fellow North Vietnam Commandos, GCMA French paratroopers were dressed with the Viet Minh regular black outfit "Cu Nao" to confuse the enemy and lightly equipped with submachine guns and rifles which are suitable weapons to perform hit-and-run ambushes against out of guard logistical convoys. Hmong partisans were dressed with their traditional black costume with a red silk belt and most of them were barefoot.
Failure
The Sam Neua team, which was in advance, as it was closer to Dien Bien Phu, joined Sassi's GCMA and taped it into the outpost. According to Sassi, the heading commandos were only a few dozens of kilometers from Éliane.
Éliane fell on May, 1st. Eventually, Dien Bien Phu surrendered on May 7, 1954, though Sassi's emergency column found rare Dien Bien Phu survivors who had escaped through the jungle, approximatively 150.[3]
After the war, the military jury charged General Cogny—who ordered the Dien Bien Phu garrison to surrender from his base in Hanoi—for the operation's failure as the "emergency column" GCMA was parachuted too late.[1]
