The Franco-Italian army led by Eugène de Beauharnais was defreated by an Austrian army commanded by a member of what house?
Battle of Sacile The Battle of Sacile (also known as the Battle of Fontana Fredda) on 16 April 1809 and its companion Clash at Pordenone on 15 April saw an Austrian army commanded by Archduke John of Austria defeat a Franco-Italian army led by Eugène de Beauharnais and force it to retreat. Sacile proved to be the most notable victory of John's career. The action took place east of the Livenza River near Sacile in modern-day Italy during the War of the Fifth Coalition, part of the Napoleonic Wars.
Battle of Montereau The Battle of Montereau (18 February 1814) was fought during the War of the Sixth Coalition between an Imperial French army led by Emperor Napoleon and a corps of Austrians and Württembergers commanded by Crown Prince Frederick William of Württemberg. While Napoleon's army mauled an Allied army under Gebhard Leberecht von Blücher, the main Allied army commanded by Karl Philipp, Prince of Schwarzenberg advanced to a position dangerously close to Paris. Gathering up his outnumbered forces, Napoleon rushed his soldiers south to deal with Schwarzenberg. Hearing of the approach of the French emperor, the Allied commander ordered a withdrawal, but 17 February saw his rear guards overrun or brushed aside.
