Pierre Langlais’ group survived only by a miracle. The colonel himself was standing naked beneath a pierced-fuel-drum shower when the barrage began, and ran unclad into his bunker, seconds before a shell exploded on its roof. He and his officers were left stunned in a chaos of fallen timbers, debris, earth and wrecked equipment; yet a second shell failed to explode. Elsewhere, a red and yellow fireball marked the eruption of the camp’s fuel and napalm dump. All but one of de Castries’ spotter aircraft were wrecked.
As the light faded on 13 March, defending commanders found themselves crippled. Many phone lines had been cut, and radios were working poorly in the usual evening atmospheric mush. The 450-strong Foreign Legion battalion holding Béatrice was understrength and short of officers. Commanders expected an attack, but not before nightfall. The Vietminh had excavated trenches within fifty yards of Béatrice’s perimeter, and from these their infantry stormed forward amidst a cacophony of cries and bugle calls, followed by detonations as bangalore torpedoes exploded beneath the defenders’ wire. Artillery dealt the deadliest blows: at 1830 a shell devastated Béatrice’s command post. As darkness deepened, the occupants of each bunker on the hill were obliged to fight isolated battles beneath the glow of flares. Some Legionnaires imposed heavy losses upon the attackers before succumbing. Within an hour, however, and exploiting a ruthless disregard for their own casualties, the Vietminh occupied positions deep inside the defences.
One French company commander continued to radio for gun support even as his trenches were overrun: ‘Right 100 … 100 nearer … 50 nearer … Fire on me! Les Viets are on top of us!’ Then there was only a hiss of static, as the voice fell silent. Col. Gaucher, who had gloomily predicted to his wife that he and his comrades were ‘destined for sacrifice’, was mortally wounded. Langlais was ordered to take over, but lacked phone and radio links. Soon after midnight the Vietminh secured control of Béatrice, having killed over a hundred defenders and captured twice as many, most of them wounded. Just a hundred men led by a sergeant-major made good their escape. When sunrise came at 0618 on the 14th, a strange silence overhung the battlefield, under a drizzle that turned to heavy rain. The camp’s medical staff emerged blinking and exhausted from their stifling bunker, having handled ten abdominal and ten chest cases, two cranials, fifteen fractures and fourteen amputations. Debris lay everywhere: blackened and burnt-out vehicles, smashed aircraft and equipment. A belated and futile air attack was launched against the Vietminh gun positions.
Then a wounded officer prisoner, Lt. Frédéric Turpin, staggered across from Béatrice to Dominique, bearing from the Vietminh the offer of a truce to evacuate casualties, which Cogny’s headquarters authorised. This was a shrewd psychological move by Giap, since it passed to the garrison responsibility for eight badly wounded men, and acknowledged his army as local victors. Turpin was fortunate enough to secure air evacuation to Hanoi. As for the men who remained, Pierre Rocolle wrote: ‘A stupor fell upon all those not engaged in urgent tasks. Officers and men could not stop asking themselves: “How could a Legion unit have been so swiftly overcome?”’ Cogny’s response was to reinforce the garrison with yet another battalion of paratroopers.
Giap prepared to repeat his success against Gabrielle, further north, defended by the 7th Algerian Tirailleurs, who ate supper in anticipation of a busy night. Sure enough, at 1800 on the 14th, just before sunset, men of the Vietminh’s 308th Division hurled themselves forward. A bitter struggle continued into darkness, lit by flares dropped from an orbiting Dakota. For some hours the defenders clung on, with French artillery harrowing the Vietminh infantry. At 0330 on the 15th, however, renewed communist fire fell on the hill, scoring a hit on the command post which killed or wounded most of its occupants. The French hoped to counter-attack at daybreak, and defending officers were heartened by news of tanks and paras concentrating in readiness. The Algerians had had enough, however. At 0700 on the 15th the first Vietminh soldiers appeared on the crest of Gabrielle. The Tirailleurs, including one company which had not been engaged, scrambled out of their trenches and ran pell-mell down the hill. The communists took possession, and found the battalion’s concussed colonel among 350 prisoners and eighty dead. The newly-arrived Vietnamese battalion was committed to counter-attack across open ground, but in the face of shellfire its men faltered: the assault was abandoned as Tirailleur fugitives trickled into the camp’s shrunken perimeter.
French leaders reeled under this second blow within twenty hours, and chose to attribute blame for Gabrielle’s loss to its officers. Navarre observed in a letter to Marshal Juin in Paris that the collapse of morale had been ‘most conspicuous in the command elements, which had previously displayed high confidence (too much of it, indeed) and tended to veer from one extreme to the other’. The general dispatched two volunteer colonels to Dienbienphu to replace those who had fallen. With the air force conspicuously failing to interdict Giap’s supply routes, Navarre instead proposed a ludicrous scheme to seed rainclouds over the jungle, inundating the communists.
In the camp, several of de Castries’ headquarters officers suffered nervous collapses: the chief of staff sat motionless in his bunker, refusing to remove his helmet. De Castries himself exercised command, but not leadership: he offered his men no ringing oratory nor comradely cheer, instead apparently resigning himself to the administration of a descent towards disaster. Communist howitzers turned their attentions upon French artillery, of which the gunners suffered terribly: one-third of 155mm crews and more than 50 per cent of de Castries’ 120mm mortarmen became casualties. By the third day of battle, half the garrison’s stock of twenty-seven thousand shells was already expended. The French had lost their forward observation positions, so that their remaining guns were forced to fire almost blind, dependent for targets on air photographs of Giap’s lines processed in Hanoi, then parachuted into the camp.
De Castries’ artillery commander, the jolly, roly-poly Col. Charles Piroth, had rashly promised that he could suppress any guns the communists deployed. Now he suffered a lacerating verbal assault from Langlais about the failure of his batteries during the first two nights’ fighting. The colonel retired to his bunker, sobbing despairingly, ‘I am completely dishonoured.’ In truth, it was his superiors who merited disgrace, for choosing to fight a battle in such a place, pitting twelve thousand French and colonial troops against five times their number of Vietminh, led by a commander of brilliance. Piroth nonetheless clutched a grenade to his body, then jerked forth the pin. De Castries sought to conceal the colonel’s suicide, but the news quickly leaked, and was published in Le Monde. On the night of 14 March several shells fell on the main dressing station, killing fourteen men in the triage room and nine post-operative cases, as well as destroying the X-ray facility. Thereafter the wounded suffered terribly: before the end, doctors and surgeons treated 2,665 men, performed 934 operations and watched 319 patients die. The camp’s airstrip continued to be raked by fire which destroyed ten aircraft stranded by bad weather.
The next two days, 15–16 March, passed almost without incident. Vietminh propaganda loudspeakers broadcast surrender appeals to the defenders in French, Vietnamese, Arabic and German. These were not without effect: Cogny had included in Dienbienphu’s garrison, against de Castries’ strongly-expressed wishes, one Vietnamese and two Thai battalions that were known to be unreliable. French officers had always feared that peace negotiations must precipitate a catastrophic unravelling of their local forces, and so it proved. Following the announcement of the looming Geneva conference, many Vietnamese in French service saw who was winning the struggle for Indochina – and that it was not the colonial power. During the night of 15 March, the first trickle of what swelled into a river of desertions took place from the Thai battalion manning position Anne-Marie, a mile and a half south-west of Gabrielle: one strongpoint was entirely abandoned. Shortly afterwards Vietminh bombardment precipitated a wholesale flight. A French forward
