The raid at Altenburg on 28 September 1813 took place during the War of the Sixth Coalition's German Campaign of 1813.

[2][4] The battle was the culmination of a raid in which Thielmann cavalry successfully attacked Napoleon's lines of communications along the roads between Erfurt and Leipzig in the Saale valley.

[2][5] Thielmann completely surprised and routed a larger force of French cavalry, including Cavalry of the Imperial Guard and a small force of 2nd Baden Infantry Regiment (Infanterie-Regiment No.2 ‘Markgraf Wilhelm’) nominally under the command of Lefebvre-Desnouettes numbering some 8,000.

The French, completely surprised, broke and fled from Altenburg losing a third of their number (2,100), in the process running over the Baden infantry which was taken prisoner despite attempting to resist.
