The Battle of Limonest (20 March 1814) saw 30,000-53,000 Austrian and Hessian troops led by Prince Frederick of Hessen-Homburg defeat 20,000-23,000 French troops under Marshal Pierre Augereau.
Background
While Napoleon faced the main Allied armies of Karl Philipp, Prince of Schwarzenberg and Gebhard Leberecht von Blücher to the east of Paris, a secondary campaign was conducted near Lyon to the south. In January 1814 the Austrians easily captured large swaths of territory, but failed to seize Lyon. By mid-February, a reinforced Augereau managed to recapture some towns, posing a threat. Anxious for his supply line back to Germany, Schwarzenberg sent Prince Hessen-Homburg large forces to protect his southern flank.
Battle
After some stiff fighting, the Allies forced the outnumbered French defenders to withdraw from a line of hills north of Lyon in this War of the Sixth Coalition action.
Aftermath
Lyon, in 1814 the second largest city in France, was abandoned to the Allies as a direct result of the defeat. With greatly superior forces, Hessen-Homburg pressed the French back in a series of battles and captured Lyon on 22 March.
