Meanwhile, the enemy drew ever closer. Two weeks earlier Vo Nguyen Giap had abandoned mass assaults in favor of grignotage, or “nibbling away” of the French positions, in a replay of the trench warfare tactics of the Ypres salient in World War I. Hundreds of sappers were deployed to push assault trenches ever closer to the fortifications, a practice, Giap told associates, that would allow the Viet Minh “completely to intercept reinforcements and supplies.” Lead elements would dig a deep hole at the bottom of the trench and pass the dirt to the rear, where it would be immediately put in sandbags, while other workers brought forward logs and wooden beams to provide the diggers with overhead cover. It was a simple, beautifully efficient system. On most nights the defenders of Eliane could hear the clinking of picks and shovels almost under their feet, sometimes with their naked ears and sometimes using crude geophones made of a combination of wine canteens and medical stethoscopes. This too was reminiscent of Passchendaele forty years earlier, when German troops heard miners from Wales digging beneath them on Messines Ridge, in preparation for blasting them out.
Why did Giap shift tactics? With the French seemingly on the ropes in the second week of April, why did he not seek a swift and conclusive victory, a coup de grâce? Mostly because neither he nor his subordinate commanders could accept the casualty rates the French had been inflicting on them in the first month of the fighting. They needed a respite. Of the total number of dead and wounded that the Viet Minh suffered during the battle for Dien Bien Phu, close to half had been suffered already by April 5. Roughly four thousand of these were fatalities. Many of the losses occurred during intense fighting on strongpoints Dominique, Eliane, and Huguette, but French aerial attacks also could have devastating effect. C-47 transports were equipped with depth-charge racks to allow napalm drums to be unloaded swiftly. These were fused to explode twenty yards above the ground. Larger C-119s swept low, then pulled up abruptly while napalm cans slid out. The actual damage done by these attacks was often marginal, especially when poor weather and antiaircraft fire made accurate targeting impossible, but the mere anticipation that such a weapon could fall from the sky was acutely unnerving to defenders.
By mid-April, various reports indicated growing despondency among Viet Minh troops. Fiery speeches by political commissars about sacrifice, duty, and the need to stamp out Franco-American imperialism were duly given, but these worked best on new recruits anticipating quick success; they rang hollow to weary veterans of the frontal attacks who had witnessed comrades being slaughtered all around them and who themselves might have sustained wounds. French radio intelligence picked up agitated dispatches from lower-unit commanders reporting that some units were refusing orders, and a Viet Minh deserter told the French on April 20 that new recruits were despondent about the difficulties of the struggle. The commissars had to press all the harder, especially at recovery stations where soldiers were convalescing, insisting that the fight must go on as long as necessary, regardless of losses.
Many of the new recruits had walked to Dien Bien Phu, often in groups of about a hundred, usually for long distances through difficult terrain, only to find conditions worse after they arrived. Though the People’s Army had the luxury of rotating units between the trenches and rest areas in the surrounding jungle, this brought only limited relief. Even in the rear areas, men generally slept only on bamboo mats or banana leaves on plastic mats. Few had mosquito nets, and malaria was endemic. Quinine to treat the illness was in short supply, so much so that soldiers would have to pass around a cup of water containing one dissolved tablet, take a sip, and send it on. When the rains started for real about April 25, the conditions deteriorated, and not only for those in the trenches. Sickness increased, and the situation for the wounded, deplorable to begin with, deteriorated further. Gangrene cases proliferated. Ton That Tung remained the only real surgeon on his side, and along with his six assistants he waged a hopeless struggle to treat the wounded, lacking modern drugs and instruments and sometimes forced to operate while standing knee-deep in water. As before, head injuries were a particular problem, and Tung taught the assistants his method of removing foreign bodies by suction and then closing the skull. With no electrocoagulators at their disposal, the team resorted to touching the blood vessels with white-hot platinum wire.

THE ASSAULT BEGAN ON MAY 1, AT THE USUAL TIME: LATE AFTERNOON. All day long evidence had accumulated in General de Castries’s command bunker that something was afoot, and by early afternoon the deadly smell of all-out assault hung in the air. Probing attacks down the trench lines were being made in greater strength, and radio intercepts detected the presence of Viet Minh battalions in concentration. The previous three nights had seen more downpours, and on April 29 some parts of the garrison reported three feet of standing water in the trenches. Their boots and clothing perpetually soaked, the men were also hungry, for everyone was now on half rations. April 30 brought a modicum of good news, in the form of an agreement by the American crews from CAT to resume their C-119 flights, in exchange for a promise from the French Air Force to do a better job of suppressing enemy flak (a promise it failed to keep). Supply drops increased dramatically that day and on May 1, and when the assault began, there was again three days of food available, along with desperately needed ammunition.
Just before five o’clock in the afternoon, the artillery barrage commenced. More than one hundred Viet Minh field guns opened up over the whole area of the camp. Bunkers and soggy trenches collapsed under the bombardment, many of their occupants buried alive. After three hours, the firing slackened, whereupon the entire 312th and 316th Divisions stormed up the eastern hill positions of Eliane and Dominique and the 308th targeted Huguette. Dominique 3, defended by a motley mix of Algerians and Tai, fell quickly, and by 2 A.M. Eliane 1 had succumbed as well. In nine hours of fighting, the garrison had lost 331 killed or missing. Was this the beginning of the end? Senior French commanders feared it was. Colonel Langlais wired Hanoi soon after the assault began: “No more reserves left. Fatigue and wear and tear on the units terrible. Supplies and ammunition insufficient. Quite difficult to resist one more such push by Communists, at least without bringing in one brand-new battalion of excellent quality.”
…
What a task they faced! Giap’s attacking force consisted of four infantry divisions, plus thirty artillery battalions and some one hundred guns. In response, the defenders could offer very little except the courage and fortitude borne of desperation. In this respect it was to their advantage that their perimeter had shrunk: It now consisted mostly of portions of Huguette, Claudine, and Eliane, perhaps one thousand yards square, plus the isolated Isabelle three miles to the south. To cover the approach to the hospital, which that morning held more than sixteen hundred wounded, and improvised strongpoint christened Juno had been created between Claudine and Eliane. Total troop strength stood at roughly 4,000, though in terms of infantry in the central sector it was closer to 2,000. There were Foreign Legion and Vietnamese parachutists, Moroccan Rifles, Tai from various dissolved units, French paratroop battalions (half of them Vietnamese), Arab and African gunners, and, down on Isabelle, still some Algerians. The greatest concentration of men, some 750 parachutists, was deployed at the point of maximum import and danger, the top of Eliane.
At four P.M., the Viet Minh artillery bombardment began. Its purpose was mostly to cover the assembly of assault infantry in forward positions, and it featured the unleashing of a wholly new weapon in the 351st Heavy Division’s arsenal: the “Stalin Organs.” Modeled on the twelve-tubed Katyusha rocket launchers that the Red Army had used with devastating effect against the Wehrmacht in World War II, these projectors announced their presence with the terrifying screeching noise of their rockets, which one legionnaire likened to the sound of a passing train. The explosions that followed were louder and often more destructive than those of shells of larger caliber, for the explosive made up a greater proportion of the rocket’s weight. Several of the rockets scored direct hits, destroying munitions stores, pulverizing sodden earthworks, and doing serious damage to the medical supplies depot. That night the garrison’s senior medical officer cabled Hanoi: “Situation of the wounded extremely precarious due to flooding and collapse of several dugouts.… Urgent need of all medical supplies; my stocks are destroyed.”
…
Sometime before eleven (accounts differ on the exact time), a massive explosion shook the earth under Eliane 2. In a tactic reminiscent of the Union at Petersburg in 1864 and the British at the Hawthorn Redoubt in 1916, the Viet Minh had driven a mine shaft under Eliane 2 and loaded it with three thousand pounds of TNT. Veterans recalled a muffled rumbling under their feet, followed after a pause by a giant geyser of earth and stones thrown into the air. The garrison suffered massive casualties, but the key French blockhouse did not fall, and the Viet Minh foolishly paused before advancing. This delay gave the defenders under Captain Jean Pouget precious time to man the lip of the crater and open a murderous fire on the approaching infantry. Three hours later, with Pouget’s men still holding out, he asked for reinforcements. He could hold Eliane 2, he told HQ over the wireless, with just one additional company. None was available, replied the major on the other end. “Not another man, not another shell, my friend. You’re a para. You’re there to get yourself killed.”
Pouget did not die. After acknowledging the major’s message, he announced his intention to sign off and to disable the radio. A Viet Minh operator who had been eavesdropping broke in and told him not to wreck the set just yet—a song was coming on. Through the static Pouget could hear the strains of “Chant des Partisans,” a wartime anthem of the French Resistance. “The swine,” he grumbled, grasping the irony. He put three bullets through the radio and went out to join his men. A few minutes before five o’clock, he and his last handful of soldiers were surrounded and captured.
The end was near. On May 7, the sun went up for the last time on the fortified French camp. Eliane 4 and 10 were still holding out at daybreak, but by midmorning both were gone.
…
The Battle of Dien Bien Phu was over. The Viet Minh had won. Vo Nguyen Giap had overturned history, had accomplished the unprecedented, had beaten the West at its own game. For the first time in the annals of colonial warfare, Asian troops had defeated a European army in fixed battle.
