Battle of Günzburg
German Campaign (War of the Third Coalition) · Günzburg, Bavaria (Holy Roman Empire)
Summary
Lannes was ordered to seize the bridges over the Danube at Günzburg to cut Austrian retreat to the east. He launched several assaults against Austrian defenses protecting the strategic crossings.
Historical context
The Battle of Günzburg formed part of the encirclement maneuver against Mack's Austrian army at Ulm. Control of the Danube bridges was essential to cut enemy lines of retreat and supply.
Tactics
Marshal Ney had Mahler attack Günzburg while Dupont threatened Ulm from Albeck. Surprised while crossing a bridge over the Günz in marshy ground, the Austrians fell back toward the town in confusion; Mahler seized one of the town gates and took the bridges over the Danube.
Consequences
Capture of Günzburg by Mahler's division, with five guns and about 900 prisoners, interrupted Mack's attempt to evacuate Ulm toward Bohemia. Forced to turn back overnight, the Austrian general tightened the encirclement of his army, which would capitulate at Ulm on 20 October 1805.
