Diên Biên Phu - The Lessons of a Defeat

The long ordeal of the French Expeditionary Corps, from Diên Biên Phu to its departure from Indochina.

7 May 1954. The fall of Diên Biên Phu. The Viet Minh's spectacular victory after fifty-six days of fighting seals France's departure from a part of the world where it had been present for more than a century. Seventy years on, Pierre Servent does not exhume this Indochina battle merely to observe the customary ritual of anniversaries, but examines the lessons it still has to offer us, including for today.

Despite the singular features specific to this Indochina conflict, the author identifies the same "French malaise" already identified in national wars — the great recurring failings that fostered failure: the same endless quarrel among commanders while the conflict rages, the same misalignment between political power and the military sphere, the same arrogance that leads to underestimating the enemy and overestimating oneself, the same taste for ready-made ideas instead of a reality-based approach on the ground, the same refusal to take into account the weak or strong danger signals sent by intelligence officers, the same carelessness allowing enemies to know plans in advance, the same permanent gap between ambitions and the means allocated, the same political flippancy preventing any sustained continuity of effort.

But the defeat can also be explained by the fact that, structurally, the Marxist enemy was spared many of these French failings, benefiting from certain advantages inherent in the very nature of its ideological regime. If Diên Biên Phu did not bring about an immediate end to the fighting — the last French soldier did not leave Indochinese soil until 14 September 1956 — it was a highly symbolic battle whose full intensity Pierre Servent brings back to life for the reader, before recounting the final months of France in Indochina.
