Southern Germany Strategic Map
On 15 February 1813 Marshal Schwartzenberg crossed the Bavarian border and dispersed the small covering force and took the city of Passau
The majority of the Bavarian Army was in northern Germany as part of Napoleon’s new Grande Armee. He considered the Austrian’s to be allies, and only a small reserve Army was left in Bavaria to contain the ongoing rebellion in the Tyrol.
Schwartzenberg defeated the Bavarian Army and entered Munich on 20 February 1813.
On receiving news of the Austrian betrayal and invasion of Bavaria, Napoleon ordered Marshal Oudinot to form the Third French Army from the Bavarian and Baden troops forming part of the Grande Armee and march south to drive Schwartzenberg out of Bavaria.
By the end of February 1813 Oudinot had concentrated the newly formed Third French Army at Ulm and was ready to cross into Bavaria and engage the Austrians.
Schwartzenberg had secured Munich and deployed his Army just west of the city.
