Jean-Baptiste d'Autriche
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.
