In the Battle of Wertingen Imperial French forces led by Marshals Joachim Murat and Jean Lannes attacked a small Austrian corps commanded by Feldmarschall-Leutnant Franz Xaver von Auffenberg. This action, the first battle of the Ulm Campaign, resulted in a clear French victory. Wertingen lies 28 kilometres (17 mi) northwest of Augsburg. The combat was fought during the War of the Third Coalition, part of the Napoleonic Wars.

The Ulm campaign was a series of French and Bavarian military maneuvers and battles to outflank and capture an Austrian army in 1805 during the War of the Third Coalition. It took place in the vicinity of and inside the Swabian city of Ulm. The French Grande Armée, led by Napoleon, had 210,000 troops organized into seven corps and hoped to knock out the Austrian army in the Danube before Russian reinforcements could arrive. Rapid marching let Napoleon conduct a large wheeling maneuver, which captured an Austrian army of 23,000 under General Mack on 20 October at Ulm. That brought the total number of Austrian prisoners-of-war in the campaign to 60,000. The campaign is by some military historians regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century. Napoleon himself wrote:four months of marching about, months of fatigue and wretchedness, have proved to me that nothing is more hideous, more miserable, than war. And yet our sufferings in the Guard are not to be compared with those of the line.
