The Battle of Eckmühl took place from April 19 to April 22, 1809, during the War of the Fifth Coalition. This conflict involved the forces of Napoleon Bonaparte against the Austrian Empire. The battle was significant as it showcased Napoleon's military strategy and his ability to maneuver his troops effectively against a larger Austrian army. The French army achieved a decisive victory at Eckmühl, leading to the capture of the Austrian city of Regensburg. This battle was part of a larger campaign that ultimately resulted in the defeat of Austria and the signing of the Treaty of Schönbrunn later that year.
