(July 11, 1302), military engagement on the outskirts of Kortrijk in Flanders (now in Belgium) in which an untrained Flemish infantry militia, consisting mainly of members of the craft guilds (notably that of the weavers) defeated a professional force of French and patrician Flemish cavalry, thus checking the growth of French control over the area. It is so named for the spurs supposedly taken from the vanquished. The towns of Flanders rebelled against the occupying French army and besieged the French garrison at Courtrai castle. France then sent a relief army. The ill-armed militia prevailed over the mounted force by making its stand on a patch of ground surrounded by streams and moats, thus frustrating any attempt at a rapid cavalry charge; the marshy terrain also impeded other efforts of the horsemen. This victory led to a generation of political ascendancy of the weavers' guild in the urban centres and ended the threat of French annexation. It also began the “infantry revolution” of the 14th century. The Scots, at the Battle of Bannockburn (Bannockburn, Battle of) (1314), consciously emulated the Flemings, and their victory led the English to fight on foot—and win—against the French at the Battle of Crécy (Crécy, Battle of) (1346) and the Battle of Poitiers (Poitiers, Battle of) (1356).
