In 1813 Tauentzien was named Military Governor between the Oder and the Vistula Rivers, and he succeeded in the siege of Stettin. As General der Infanterie, he commanded the IV. Armeekorps, which consisted mostly of Landwehr, and participated in the battles of Großbeeren on 23 August and Dennewitz on 6 September. In October his troops left the relative safety of Dessau and crossed the Elbe.
