The Battle of Simbach on May 9, 1743, took place during the War of Austrian Succession near Simbach am Inn.

It ended with a heavy defeat of the Bavarian troops against the Austrians.

Altogether the loss of dead and captured Bavarians, Palatines and Hessians amounted to about 4,000 men, the Austrians only lost a little over a hundred men.

Simbach was completely destroyed except for one house, and the surrounding area was also devastated.

Soon after, the French-occupied towns of Dingolfing, Landau and Deggendorf were also taken by the Austrians.
