Archduke John of Austria Archduke John of Austria (German: "Erzherzog Johann Baptist Joseph Fabian Sebastian von Österreich" ; 20 January 1782 – 11 May 1859), a member of the House of Habsburg-Lorraine, was an Austrian field marshal and Imperial regent ("Reichsverweser") of the short-lived German Empire during the Revolutions of 1848.
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.
