The Battle of Festenburg was fought in 1759 between the armies of France and Great Britain amid the Seven Years' War.
Having defeated two Anglo-German armies near Lutter, Victor-Francois de Broglie marched his army south to confront an encamped field army in the Upper Harz Mountains. Along the way, he was confronted by an Anglo-German army near the village of Festenburg. In the ensuing battle, the French right-wing cavalry broke through their Hessian counterparts before slaughtering the British cannoneers. The French left-wing cavalry broke the British veteran foot facing them, and the combined French cavalry forces helped relieve the embattled French infantry in the center by charging the vulnerable rears of the British and German regiments. The French won a costly victory, and they quickly replenished their losses with their deep reserves of around 15,000 men, even as they ran out of ammunition reserves.
