The Austrians under Karl Josef Batthyány defeated the outnumbered French under General Ségur, ending the war in Bavaria.

His 18-year-old son and heir Maximilian III Joseph wavered between the Peace-party, led by his mother Maria Amalia, Holy Roman Empress and Army Commander Friedrich Heinrich von Seckendorff and the War-party, led by Foreign Minister General Ignaz von Törring and the French envoy Chavigny.

The French Army commander Henri François de Ségur was not informed of this manoeuver and waited unaware and unprotected near Pfaffenhofen on Palatinate reinforcements under General Zastrow, which arrived on 14 April.

But the Austrians took the town in house-to-house combat in which the fierce Croatian Pandurs inflicted heavy casualties on the French defenders.

de Ségur had lost many troops and material, but his maintenance of discipline had prevented the total destruction of his army.
