Abensberg 1809 order of battle

The Battle of Abensberg was fought on 20 April 1809, between an Allied force under the command of Emperor Napoleon I of France on one side and three Austrian corps led by Johann von Hiller, Archduke Louis of Austria, and Michael von Kienmayer. The Austrians formed the left wing of Archduke Charles, Duke of Teschen's main army and were under the overall command of Hiller. Napoleon's French troops, reinforced by troops from the Kingdom of Bavaria and the Kingdom of Württemberg outfought their opponents, inflicted heavy losses, and forced the Austrians to retreat to the southeast.

During the fighting, 55,000 French and Germans faced 42,000 Austrians. Of these, only about 25,000 on each side became involved in the fighting. The Austrians lost 2,710 killed and wounded, plus about 4,000 captured. Allied losses were 215 Frenchmen, 146 Württembergers, and 746 Bavarians, for a total of 1,107.
