The Battle of Kaiserslautern saw a Coalition army under Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel oppose a Republican French army led by Lazare Hoche. Three days of conflict resulted in a victory by the Prussians and their Electoral Saxon allies as they turned back repeated French attacks. The War of the First Coalition combat was fought near the city of Kaiserslautern in the modern-day state of Rhineland-Palatinate, Germany, which is located about 60 kilometres (37 mi) west of Mannheim.

Louis Lazare Hoche was a French military leader of the French Revolutionary Wars. He won a victory over Royalist forces in Brittany. His surname is one of the names inscribed under the Arc de Triomphe, on Column 3. Richard Holmes describes him as "quick-thinking, stern, and ruthless... a general of real talent whose early death was a loss to France."
