The Battle of Haslach-Jungingen, also known as the Battle of Albeck, fought on 11 October 1805 at Ulm-Jungingen north of Ulm at the Danube between French and Austrian forces, was part of the Ulm campaign during the War of the Third Coalition, which was a part of the greater Napoleonic Wars. The Austrians, despite their numerical advantage, were unable to make good use of it due to indecision resulting from an overestimation of the French numbers and the local terrain. The outcome of this battle was a French victory.
