The Battle of Haslach was a French victory over the Austrians on the 11th of October 1805 during the Napoleonic Wars at Haslach. A 6000-strong French force under General Pierre Dupont de L'Etang was marching on Ulm when he was stopped by an Austrian force of 60000 troops under the Archduke Ferdinand which commanded the heights around his route. He immediately occupied and fortified the village of Haslach, which was then attacked by about 25000 of the Austrians. Dupont managed to hold them off until nightfall, then disengaged and withdrew, taking 4000 Austrian prisoners with him. Research Battle of Haslach
