A king's victory at Fontenoy cost thousands of lives and yielded almost nothing
In 1745, the French army secured a hard-fought triumph against British-led forces at Fontenoy. While the battle cemented the reputation of Marshal Saxe and boosted French morale, the strategic gains were fleeting. By 1748, the exhausted nation surrendered its hard-won territorial conquests for virtually no return, leaving observers baffled.
The Battle of Fontenoy, fought on 11 May 1745, was a pivotal clash in the War of the Austrian Succession. Marshal Saxe, commanding 50,000 French troops, established a fortified position near Tournai to draw the Pragmatic Army into a decisive engagement. The Allied force, led by the 24-year-old Duke of Cumberland, consisted of 50,000 men, including British, Hanoverian, and Dutch contingents. Cumberland’s command was hampered by internal divisions, his own inexperience, and a failure to properly scout the French defenses, which included hidden redoubts.
The fighting reached a climax when a massive Allied infantry column pushed toward the French center. In a famous, though debated, anecdote, the British Guards allegedly invited their French counterparts to fire first. The resulting exchange decimated the front lines, but the Allied column eventually stalled. Saxe utilized his reserves and artillery to force a retreat, inflicting heavy casualties on both sides. Total losses reached up to 12,000 for the Allies and 8,000 for the French, making it the bloodiest engagement in Western Europe since 1709.
Despite the tactical victory, France faced severe economic strain from a British naval blockade. By the time the Treaty of Aix-la-Chapelle was signed in November 1748, the French economy was failing and food shortages were widespread. Louis XV ultimately returned the captured Austrian Netherlands, a move so unpopular it inspired the derisive phrase 'as stupid as the Peace.' The conflict also signaled the waning influence of the Dutch Republic, which struggled to maintain its status as a leading European power throughout the campaign.
The battle left a complex legacy. For Irish nationalists, the participation of the Irish Brigade became a symbol of military pride, leading to memorials in the village of Fontenoy. Conversely, Louis XV reportedly reflected on the human cost of the triumph, a sentiment later commemorated by a memorial in Vezon. While Saxe was celebrated by contemporaries like Frederick the Great, the battle ultimately served as a reminder of the futility of 18th-century warfare when decoupled from sustainable statecraft.
