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 observer radioed laconically: ‘The Thais are off.’ Anne-Marie 1 and 2 fell into Giap’s hands almost bloodlessly, and he promptly repositioned there his own mortars and recoilless rifles.
Garrison morale was now crumbling in such a fashion that Giap’s formations could probably have overrun the entire camp – as his subordinate officers chafed to do. De Castries wrote later of the chasm between the spirit of the defenders and that of the enemy as being ‘between the men of a national army fighting for independence … and a mercenary force honouring a contract’. Giap, however, refused to be hurried. Dogged, methodical preparation had served him well. Moreover, his formations had bled heavily for their early successes: around a quarter of the infantry attacking Béatrice are thought to have fallen, and one of the battalions assaulting Gabrielle lost 240 dead. Six half-trained Vietminh medics struggled to tend seven hundred wounded.
Amid cascades of shell and mortar fragments, the besiegers paid dearly for their lack of steel helmets, and for early ‘human wave’ attacks. They laboured all night, every night to deepen trenches and extend saps: timber props were carried miles from the nearest forest to the battlefield. A wholesale call-up of reinforcements, many of them untrained teenagers, was undertaken across communist-controlled northern Vietnam: the martyrdom which took place at Dienbienphu was by no means exclusively a French one.
Giap each day studied graphs of supply deliveries – ‘the moving red line’. One morning he demanded of his logistics chief why not a single ton of rice had been delivered the previous night, and was told there had been torrential rain. The general responded, ‘Whether it rains or hails, we cannot allow our soldiers to fight on empty stomachs!’ This was cynical verbiage: he knew full well that many of his men were starving. They received scarcely any meat or vegetables, and by mid-March were eating ‘rice so rotten that we did not know how to cook it’, in the words of a man of the 312th Division. They were deprived of cigarettes, reduced to foraging for edible wild roots and plants.
Yet Giap chose to persist with his assault in the manner he had started it, painstakingly ensuring the success of each thrust, denying to the French any revival of hope. His 37mm flak guns inflicted a crippling toll on aircraft, so that scarcely one returned from the camp unscathed. Through the days and weeks that followed the fall of three of de Castries’ nine hills, Vietminh artillery harried the airstrip. The landing of each of the diminishing procession of medevac flights precipitated a panic-stricken surge of would-be passengers, wounded and otherwise. Photojournalist Jean Péraud filed a dispatch describing the scene, which he likened to 1945 Germany: ‘Cries. Tears. Stampede of wounded towards the door. Never seen anything like it since concentration camp.’ On the 17th the Vietminh made another skilfully-judged ‘humanitarian gesture’, presenting the garrison with eighty-six wounded prisoners. These, of course, merely increased the pressure on the camp’s overburdened medical facilities: among the doctors’ embarrassments was disposal of a mound of amputated limbs.
French medevac crews earned no plaudits: on 23 March an H-19 helicopter landed against orders on a notoriously exposed site. As it was being loaded with wounded its crew wandered away, thus escaping the destruction by shellfire of their machine and its helpless occupants, including general’s son Alain Gambiez. A French writer observed bitterly, ‘Certainement, the helicopter crews had not been chosen from the best elements of the Air Force,’ and de Castries deplored their lack of guts. Soon, hard things were also being said about fixed-wing aircrew, who were both exhausted and demoralised. American mercenary pilots of the CIA’s airline CAT flew a growing number of resupply missions, displaying more skill and steel than their French counterparts. Especially hair-raising were napalm sorties: as one C-119 roared down the runway towards take-off, its pilot raised the undercarriage prematurely, causing the plane to career on its belly along the tarmac in a cascade of sparks, amid four tons of ‘hell-jelly’ and 1,500 gallons of aviation spirit. By some freak of fortune, the crew survived.
As for the garrison of Dienbienphu, most of the French units remained staunch, but contempt for their colonial brethren rose by the day. Not only had the Vietnamese paras failed to regain Gabrielle on the 15th, but their French officers ‘had given a deplorable example’, in the words of Pierre Rocolle. An Algerian battalion abandoned its positions and drifted away into the scrub and villages beyond the perimeter, where some hundreds of ‘the rats of Nam Youm’, as they became known, lingered for the rest of the battle, living off pillaged supplies. North African gunners and engineers remained impressively steady, but suffered fifty casualties a day even when no big attack was taking place.
It was not de Castries who became the soul of the defence, but instead Langlais, who in the words of an admiring fellow-Legionnaire ‘sang the Marseillaise for fifty-six days. He never weakened.’ The colonel, however, was no more a thinking soldier, nor indeed a tactician, than are most career heroes. De Castries confided to Navarre, ‘He has the weaknesses of his virtues.’ On the 16th Langlais was joined by Maj. Marcel Bigeard, a new arrival though an old comrade, who became another legend of the siege. The son of an impecunious Toul railway worker, after one bloody action Bigeard had recommended every para in his unit for a Croix de Guerre. This man of iron was always known by his radio call-sign, Bruno. Yet both Langlais and ‘Bruno’ were better suited to enduring a crucifixion than inspiring a resurrection.
A couple of successful sorties gave a modest boost to the garrison’s morale, but de Castries was obliged to weigh the gains of such actions, and even of routine patrolling, against the lives they cost. The plight of the wounded worsened: a certain Sgt. Leroy suffered shrapnel wounds on Isabelle on 16 March, and was at the hospital recovering when it was shelled, wounding him again. He was driven back to Isabelle in time to encounter a new bombardment which killed the driver of his truck. After rescue from the wreckage he somehow survived a stomach operation, then spent the ensuing three nights in a drainage ditch before being flown to Hanoi on 25 March.
Between the 13th and the 27th, 324 casualties were evacuated, but on the 28th Vietminh artillery wrecked a Dakota on the airstrip. Giap’s guns now ranged at will, and Maj. Bigeard led twelve hundred paras in a desperate sortie against them. In that day’s fighting the Vietminh were reckoned to have lost 350 men killed, together with many flak mountings destroyed. But the French suffered 110 casualties – a company written off, for no decisive result – and de Castries had fewer lives to play with. The airstrip’s utility was at an end: the ‘air bridge’, on which the whole Dienbienphu plan had been founded, was rent asunder. Soldiers began to lift pierced steel plank from the runway to roof trenches and bunkers: planes would not again need them.
Thereafter, the sufferings of the wounded became terrible indeed. Supplies ran short of vinogel, wine concentrate, which provided the stimulant that had been the lifeblood of generations of French soldiers. On 29 March the miseries of both sides were intensified by torrential rain, which persisted through the remaining weeks of the battle: men fought and died in a sea of mud. Now
