Ulm Campaign, John's army beat a hasty retreat eastward from its position in the mountainous Vorarlberg. He successfully linked up with the Army of Italy, led by his brother, Archduke Charles. Unfortunately for Austria, Napoleon's crushing victory at the Battle of Austerlitz ended the war before Charles and John could intervene in the Danube valley. At the beginning of the 1809 war, John controlled Feldmarschall-Leutnant Johann Gabriel Chasteler de Courcelles's VIII Armeekorps of 24,500 infantry and 2,600 cavalry, and Feldmarschall-Leutnant Ignaz Gyulai's IX Armeekorps of 22,200 infantry and 2,000 cavalry. The VIII Armeekorps assembled at Villach in Carinthia, while the IX Armeekorps massed to the south at Ljubljana (Laibach) in Carniola (now Slovenia). General-major Andreas Stoichevich with 10,000 troops faced General of Division Auguste Marmont's XI Corps in Dalmatia, a French possession since 1806. A body of 26,000 Landwehr stood ready to man garrisons and defend the Austrian heartland. John planned to have the VIII Armeekorps move southwest from Villach and the IX Armeekorps advance northwest from Ljubljana. The two forces would unite near Cividale del Friuli. Another source gave a somewhat different Austrian organization at the outbreak of war. Chasteler's VIII Armeekorps possessed 20,100 men and 62 guns in two divisions. Feldmarschall-Leutnant Albert Gyulay led the 1st Division while Feldmarschall-Leutnant Johann Maria Philipp Frimont commanded the 2nd Division. Ignaz Gyulai 's IX Armeekorps counted 22,290 soldiers and 86 guns in three divisions. The 1st Division was led by Feldmarschall-Leutnant Franz Gorup von Besanez, the 2nd Division was under Feldmarschall-Leutnant Christian Wolfskeel von Reichenberg, and the 3rd Division was directed by Feldmarschall-Leutnant Vinko Knežević. Feldmarschall-Leutnant Guido Lippa was responsible for 30,000 Landwehr and reserves. These numbers differ somewhat from Schneid's list and include Stoichevich's force as part of Knesevich's division. Before the Austrians launched the war, the Tyrol flared in a spontaneous revolt. The German-speaking Tyrolese under leaders like Andreas Hofer began driving out the Bavarian garrisons. Desiring to aid the rebellion, Charles ordered John to send Chasteler and 10,000 Austrian troops to help the Tyrolese. Ignaz Gyulai's brother Albert replaced Chasteler as the commander of a reduced VIII Armeekorps. The organization of Chastler's force is shown in the Tyrol 1809 order of battle. French strategy Aware that Austria probably intended to make war, Napoleon reinforced the Army of Italy under Eugène de Beauharnais, building the French component up to a strength of six infantry and three cavalry divisions.
