Viet Minh Logistics, 1954

From Embers of War: The Fall of an Empire and the Making of America's Vietnam, by Fredrik Logevall (Random House, 2012), Kindle pp. 530-534:

THERE FOLLOWED TEN DAYS OF RELENTLESS PREPARATION, AS ferocious as any in the history of warfare. The general mobilization of labor initiated a month earlier now took on a breathtaking pace. For on this day, January 14, nothing was yet ready. The artillery was not in place on the crests above Dien Bien Phu, and the trails to get it there had not been made ready nor even fully marked out. Farther away, huge tasks remained to get materials to the highlands, from the Chinese border at Mu Nam Quam over Provincial Route 13 to the Red River and thence via Provincial Route 41 to the area of Dien Bien Phu—a total distance of almost five hundred miles. All along this route, engineering crews and soldiers, assisted by porters, worked day and night to clear and widen and repair the roads and to keep convoys moving. The route was divided into eight sections, their endpoints marked by major obstacles such as ravines or waterways where checkpoints were set up. The Russian-made Molotova two-and-a-half-ton trucks, now numbering about six hundred, as well as a smaller number of American Dodge trucks captured by the Chinese in Korea or the Viet Minh in Vietnam, traveled only one section each; at the checkpoints, their contents were taken off by porters and reloaded on the vehicles assigned to the next stretch.

French aircraft were a constant menace, and the casualties among the porters, though never published or perhaps tallied, were undoubtedly high. (A particular menace: the new American antipersonnel bombs that spread lethal showers of small steel splinters.) But the work continued, as thousands of porters stood ready to fill in the craters or build bypasses; French crews reported with dismay that the cuts they succeeded in making in roads were often repaired within hours. To complicate the pilots’ task, elaborate efforts were made to camouflage the route wherever possible. Log bridges were constructed just under the surface of a stream to hide them, and treetops were pulled together with ropes and cables to screen the roads. Vehicles were covered with leafy branches, and tire tracks were rubbed out as soon as the trucks had passed. A primitive but effective air-warning system was fashioned, whereby spotters in treetops clanged alarm triangles or blew whistles to warn of approaching planes (none of which were jets and thus could be heard well in advance of arrival). Pilots would report seeing long lines of truck headlights suddenly go dark, long before they reached the target.

When bomb damage or natural obstacles proved too great to overcome quickly, porters were called in to carry loads themselves, often over considerable distances. They would don makeshift shoulder pads and bamboo carrying rigs, and frequently they would team up. Photographs exist of four-man teams using shoulder poles to carry the barrels and the breechblocks of 75mm Japanese mountain guns up steep wooded hillsides.

Bicycles, for years a favored mode of transport for the Viet Minh, were again called into service. Most were French-made, manufactured at Saint-Étienne or in the Peugeot factories. A specially equipped bicycle—with wooden struts to strengthen the frame and bamboo poles to extend the handlebars and the brake levers—could take more than an elephant could carry. “We mobilized all available supply bicycles,” Vo Nguyen Giap would recall, “reaching a total of 20,000.”

Every supply bicycle was initially capable of transporting 100 kilograms, and this was later increased to 200 or even 300 kilograms. One civilian coolie laborer from Phu Tho named Ma Van Thang was able to transport a total of 352 kilograms on his bicycle. The carrying capacity of transport bicycles was more than ten times greater than that of porters carrying loads on “ganh” [bamboo or wooden] poles, and the amount of rice consumed by the people transporting the supplies was reduced by a similar amount. The superiority of the transport bicycles also lay in the fact that they could operate along roads and trails that trucks could not use. This method of transportation greatly surprised the enemy’s army and completely upset his original calculations.

But the most dramatic feats were accomplished at the end, after the trucks had snaked their way to the endpoint, at Na Nham on Route 41. From here, in order to avoid detection by the French, the artillery pieces had somehow to be dragged to their emplacements, on a trail that ten days before the attack date had still to be blazed. Unloaded from the trucks, the cannons were to be transported through a chain of mountains without going through a valley, in order to cut through the foothills of the 1,100-meter-high Pu Pha Song mountain; then they were to descend again in the direction of the Pavie Piste, which linked Dien Bien Phu to Lai Chau, which they would cross near Ban To; then they were to scale another new height in order to position the battery at Ban Nghiu, from where they would fire on the French garrison at point-blank range.

...

It took seven days and nights of nonstop labor to get the heavy guns in place, with the use of block and tackle, drag ropes, and braking chocks to keep them from careening back down the slopes. The half-ton 75mm mountain guns were not the problem; they could be broken down into eleven loads that, while heavy and cumbersome, were manageable. The 105mm howitzers, however, represented an almost absurd challenge on inclines that reached as steep as sixty degrees. Commander Tran Do of the 312th Division was among the infantry pressed into this “silent battle” of “cannon-pulling” of the 105s. “Every evening when the white fog … began to descend over the plains, columns of human beings set out on the road,” he later wrote. “The [six-mile] track was so narrow that if a slight deviation of the wheels took place the artillery piece would have fallen into the deep ravine. The newly-opened track was soon an ankle-deep bog. With our own sweat and muscles, we replaced the trucks to haul artillery pieces into position.”

Fatigue and lack of supplies were a constant concern, Tran continued. Meals consisted only of rice, often undercooked, as the kitchens had to be smokeless by day and sparkless by night. And yet the work went on: “To climb a slope, hundreds of men crept before the gun, tugging on long ropes, pulling the piece up inch by inch. On the crest, the winch was creaking, helping to prevent the piece from slipping.” Then it got worse: “It was much harder descending a slope. The sight was just the reverse: Hundreds of men held onto long ropes behind the piece, their bodies leaning backwards, and the windlass released the ropes inch by inch.” In this way, whole nights were spent toiling by torchlight to gain five hundred or a thousand meters.
