The Battle of Landshut took place on 21 April 1809 between the French, Württembergers and Bavarians under Napoleon which numbered about 77,000 strong, and 36,000 Austrians under the General Johann von Hiller. The Austrians, though outnumbered, fought hard until Napoleon arrived, when the battle subsequently became a clear French victory.

Johann Baron von Hiller was an Austrian general during the French Revolutionary Wars and the Napoleonic Wars. He held an important command during the 1809 campaign against France, playing a prominent role at the Battle of Aspern-Essling.
