The killer swarms that armies can’t defeat

John Arquilla writes: Today marks the bicentennial of the culminating catastrophe that befell the Grande Armée as it retreated from Russia. This past weekend one of the French Emperor’s descendants, Charles Napoleon, traveled to Minsk in Belarus to attend ceremonies commemorating the disaster at the nearby Beresina River crossing, where thousands died — many by drowning — in a final, panicked rout in freezing weather. Bonaparte had marched deep into Russia with nearly half a million soldiers; he returned with less than 25,000.

Given that Napoleon was the great captain of his time — perhaps of all time — and that his armies had conquered and held most of Europe, the tragic events on the Beresina demand explanation. His defeat is something of a puzzle, too, as the Grande Armée won the campaign’s pitched battles fought at Smolensk and Borodino. Harsh winter weather, the commonly assumed culprit, cannot explain the result either; the first frost didn’t arrive to bedevil the retreat until just a few weeks before the Beresina crossing.

The answer to the puzzle is that Napoleon and his forces were beaten by what a young Russian hussar, Denis Davydov, called his “indestructible swarm” of Cossacks and other raiders who constantly harried the French columns on the march. They also struck relentlessly, repeatedly, and to fatal effect at the Grande Armée‘s supply lines. As David Chandler, an eminent historian of Napoleon’s campaigns, put it: “raids of Cossacks and partisan bands did more harm to the Emperor than all the endeavors of the regular field armies of Holy Russia.”

Davydov, who probably inspired Tolstoy’s character “Denisov” in War and Peace, had lobbied his superiors hard for the creation of a small force of behind-the-lines raiders. General Pyotr Bagration, not long before his death in battle at Borodino, gave Davydov permission to launch his swarm — though he detached only a single troop of riders to accompany him. This was all that Davydov needed, though, as he picked up Cossacks, freed Russian soldiers taken prisoner, and recruited willing peasants along the way. Soon the French knew no rest. In Davydov’s own words, they “had no choice but to retreat, preceded and surrounded by partisans.”

The Beresina bicentennial provides us a moment to contemplate one of history’s greatest military debacles from an alternative point of view: as an outcome driven not by the clash of hundreds of thousands of troops massed tightly on some constricted battlefield, but rather as the result of constant pinprick attacks from all directions, mounted by a relative handful of irregulars. Who acted like a swarm of bees.

Davydov’s concept of operations portended an entirely different approach to military affairs, one that would grow ever more valuable with the advance of technology. The Russian partisans of 1812 attacked French wagon convoys. Fifty years later, in the Civil War, Confederate raiders disrupted rail lines, imposing near-fatal delays on the advance of Federal forces. In World War I, T.E. Lawrence and his Arab irregulars swarmed the 800-mile-long rail line from Damascus to Medina, contributing mightily to the eventual Turkish collapse. At sea in World War II, U-boat wolf packs swarmed Allied convoys, nearly winning the war for Hitler.

Throughout the Cold War, and on into the post-9/11 era, the swarm — simultaneous attack from several directions — has been the favored fighting method of insurgents and terrorists. [Continue reading...]
