The strategy of destruction: how the Black Prince broke France's economy
In short: In 1355, the Black Prince launched a campaign that avoided major battles but achieved devastating results. By systematically burning the "fattest land in the world," he weaponized economic attrition, proving that sometimes the most effective way to defeat an army is to destroy its ability to feed itself.
Between 4,000 and 6,000 soldiers from an Anglo-Gascon army carried out a massive cavalry raid during the 1355 chevauchée. Led by Edward, the Black Prince, the expedition marched 300 miles from Bordeaux to Narbonne and back. Unlike traditional warfare, the objective was not to capture territory or engage in pitched battles; instead, it focused on "economic attrition." The French commander, Count John I of Armagnac, deliberately avoided confrontation, allowing the English to devastate a wide swathe of French territory. The campaign targeted the agricultural heartland of southern France, described by contemporaries as the "fattest land in the world." The Black Prince's forces divided into three parallel columns to maximize destruction, burning crops and specifically targeting windmills. This was a calculated move to ensure the region could not grind grain for a military surplus.
They also sacked numerous towns, including the cultural and financial center of Carcassonne, which was thoroughly fired after its population fled to the citadel. The English even captured tax records during the raid to monitor the precise scale of the economic damage they were inflicting. This strategy took the French completely by surprise due to the timing and the audacity of the march. The expedition forded rivers like the Garonne and Ariège, which the French considered impassable for large bodies. By pushing 30 miles out from their base at Narbonne, English foragers and arson parties caused panic in towns up to 100 miles away. While no territory was permanently seized, the campaign succeeded in financially crippling the French war effort by systematically dismantling its economic foundations.
The importance of this attrition is underscored by the fact that the Black Prince's treasury was in an "unusually favourable" position at the start of 1355. By choosing to burn the granaries rather than fight for every castle, he leveraged mobility and fire to create a strategic vacuum. This method of warfare—targeting the infrastructure of survival rather than the strength of the enemy's shield—remains a chillingly effective study in total war.
