The Battle of the Golden Spurs (Dutch: Guldensporenslag; French: Bataille des éperons d'or) or 1302 Battle of Courtrai was a military confrontation between the royal army of France and rebellious forces of the County of Flanders on 11 July 1302 during the 1297–1305 Franco-Flemish War. It took place near the town of Kortrijk in modern-day Belgium and resulted in an unexpected victory for the Flemish.
On 18 May 1302, after two years of French military occupation and several years of unrest, many cities in Flanders revolted against French rule, and the local militia massacred many Frenchmen in the city of Bruges. King Philip IV of France immediately organized an expedition of 8,000 troops, including 2,500 men-at-arms, under Count Robert II of Artois to put down the rebellion. Meanwhile, 9,400 men from the civic militias of several Flemish cities were assembled to counter the expected French attack.
When the two armies met outside the city of Kortrijk on 11 July, the cavalry charges of the mounted French men-at-arms were unable to defeat the mail-armoured and well-trained Flemish militia infantry's pike formation. The result was a rout of the French nobles, who suffered heavy losses at the hands of the Flemish. The 500 pairs of spurs that were captured from the French horsemen gave the battle its popular name. The battle was a famous early example of an all-infantry army defeating an enemy force reliant on heavy cavalry by means of superior numbers, the environment, and by taking advantage of their foes' overconfidence.
While France was victorious in the overall Franco-Flemish War, the Battle of the Golden Spurs became an important cultural reference point for the Flemish Movement during the 19th and 20th centuries. In 1973, the date of the battle was chosen for the official holiday of the Flemish Community in Belgium. A 1984 film called De leeuw van Vlaanderen (The Lion of Flanders) depicts a vision of the battle, and the politics that led up to it.
The origins of the Franco-Flemish War (1297–1305) can be traced back to the accession of Philip IV "the Fair" to the French throne in 1285. Philip hoped to reassert control over the County of Flanders, a semi-independent polity notionally part of the Kingdom of France, and possibly even to annex it into the crown lands of France. In the 1290s, Philip attempted to gain support from the Flemish aristocracy and succeeded in winning the allegiance of some local nobles, including John of Avesnes (Count of Hainaut, Holland and Zeeland). He was opposed by a faction led by the Flemish knight Guy of Dampierre, who attempted to form a marriage alliance with the English against Philip. Many of Flanders cities were split into factions known as the "Lilies" (Leliaerts), who were pro-French, and the "Lions" (Liebaards), who would later be referred to as the "Claws" (Klauwaerts), led by Pieter de Coninck in Bruges and seeking independence.
In June 1297, the French invaded Flanders and gained some rapid successes. King Edward I of England had been at war against Philip for three years but was obliged to withdraw most of his attention from France to face the First War of Scottish Independence. He entered negotiations with France leading to the 1299 Treaty of Montreuil, while the Flemish and French signed the 1297 Truce of Sint-Baafs-Vijve, a temporary armistice which halted their conflict. When the truce expired in January 1300, Edward had just married Philip's sister Margaret and the French invaded Flanders again. By May, they were in total control of the county. Guy of Dampierre was imprisoned and Philip himself toured Flanders while setting up a French-controlled administrative apparatus.
After Philip left Flanders, unrest broke out again in the Flemish city of Bruges in the form of a rebellion against the new French governor, Jacques de Châtillon. On 18 May 1302, rebellious citizens who had fled Bruges returned to the city and murdered every Frenchman they could find, an act known as the "Bruges Matins". With Guy of Dampierre still imprisoned, command of the rebellion fell to his allies John and Guy of Namur. Most of the towns of the County of Flanders agreed to join the Bruges rebellion, except for the city of Ghent which refused to take part. Most of the Flemish nobility also took the French side, fearful of what they perceived as an attempt by the lower classes to seize power.
To quell the revolt, Philip sent a powerful force led by Count Robert II of Artois to march on Bruges. Against the French, the Flemish under William of Jülich fielded an army of mostly infantry, drawn mainly from Bruges, West Flanders, and the east of the county. The city of Ypres sent a contingent of five hundred men under Jan van Renesse, and despite their city's refusal to join the revolt, Jan Borluut arrived with seven hundred volunteers from Ghent.
The Flemish forces were primarily town militia who were well equipped and trained. The militia fought primarily as infantry, were organized by guild, and were equipped with steel helmets, mail haubergeons, spears, pikes, bows, crossbows and the goedendag, a specifically Flemish weapon consisting of a thick, five-foot-long (1.5 m) wooden shaft topped with a steel spike. All Flemish troops at the battle had helmets, neck protection, iron or steel gloves and effective weapons. Those who could afford it also had mail armor. They were a well-organized force of 8,000–10,000 infantry, as well as four hundred noblemen acting as officers, and the urban militias of the time prided themselves on their regular training and preparation. About 900 of the Flemish were trained crossbowmen. The Flemish militia formed a line formation against the French cavalry with goedendags and pikes pointed outward. Because of the high rate of defections among the Flemish nobility, there were few mounted knights on the Flemish side; the Annals of Ghent claimed that there were just ten cavalrymen in the Flemish force.
On the other side, the French fielded an army built around a core of 2,500 noble cavalry, including knights and squires, arrayed into ten formations of 250 armored horsemen. During the deployment for the battle, they were arranged into three battles, of which the first two were to attack and the third to function as a rearguard and reserve. They were supported by about 5,500 infantry, a mix of crossbowmen, spearmen, and light infantry. The French had about 1,000 crossbowmen, most of whom were from the Kingdom of France and perhaps a few hundred recruited from northern Italy and Spain. Contemporary military theory valued a knight as equal to roughly ten footmen.
The combined Flemish forces met at Kortrijk on 26 June and laid siege to the local castle, which housed a French garrison. Anticipating a French attempt to break the siege, they prepared to face their enemies in a field battle. The size of the French response was impressive, with 3,000 knights and 4,000–5,000 infantry being an accepted estimate. The Flemish ultimately chose to break off the siege and the two forces clashed on 11 July in an open field next to the Groeninge stream.
The field near Kortrijk was crossed by numerous ditches and streams dug by the Flemish as Philip's army assembled. Some drained from the river Leie (or Lys), while others were concealed with dirt and tree branches, resulting in an uneven terrain that made cavalry charges, the main French battle tactic, less effective by limiting the momentum and maneuverability of horsemen and their mounts. The French assigned scouting parties to cover the marsh with wood planks, but they were driven off before the task was finished. The Flemish placed themselves in a strong defensive position, in deeply stacked lines forming a square. The rear of the square was covered by a curve of the river. The front presented a wedge to the French army and was placed behind larger rivulets.
The 1,000 French crossbowmen began the battle by attacking their 900 Flemish counterparts and succeeded in forcing them back. Eventually, the French crossbow bolts and arrows began to hit the main Flemish infantry formations' front ranks, but inflicted little damage due to the strong defensive lines.
