Eckmühl (formerly known in English as "Eggmuhl", in Bavaria officially as Eggmühl) is a village of Germany, in Bavaria, on the Große Laaber, 20 km S.E. of Regensburg. It is famous as the site of a battle fought on the 22 April 1809 during the War of the Fifth Coalition between the French, the Bavarians, the Württembergers under Napoleon, and the Austrians under the Archduke Charles, which resulted in the defeat of the latter. Napoleon, in recognition of Marshal Davout's great share in the victory, conferred on him the title of Prince of Eckmühl.
