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.
Frederick II, Duke of Austria Frederick II (German: "Friedrich II." ; 25 April 1211 – 15 June 1246), known as Frederick the Quarrelsome ("Friedrich der Streitbare"), was Duke of Austria and Styria from 1230 until his death. He was the fifth and last Austrian duke from the House of Babenberg, since the former margraviate was elevated to a duchy by the 1156 "Privilegium Minus". He was killed in the Battle of the Leitha River, leaving no male heirs.
