Jean-Jacques Ambert commanded a French division in several engagements during the French Revolutionary Wars. He embarked on a French ship of the line during the American Revolutionary War and saw several actions. At the start of the French Revolutionary Wars, he commanded a battalion and thereafter enjoyed a fast promotion. He led a division in action at Kaiserslautern in 1793, Kaiserslautern in 1794, Luxembourg, Handschusheim, and Mannheim in 1795, and Kehl in 1796. His career later suffered an eclipse because of his association with two French army commanders suspected of treason. He spent much of the Napoleonic Wars commanding a Caribbean island, clearing his name, and filling interior posts. His surname is one of the names inscribed under the Arc de Triomphe.

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.
