There were in fact two engagements at Landshut. The first occurred on 16 April when Hiller pushed a defending Bavarian division out of the town. Five days later, after the French victory at Abensberg, the left wing of the Austrian army (36,000 men) withdrew on Landshut (this force was once more led by Hiller). Napoleon believed that this was the main Austrian army and ordered Lannes to pursue the enemy. Lannes’s troops caught up with Hiller on the twenty-first. Hiller had decided to defend Landshut to allow his baggage train to withdraw. The Battle of Landshut took place on 21 April 1809 between the French, Württembergers (VIII Corps) and Bavarians (VII Corps) 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.
