As the Prussians were running out of supplies, Platen's force was ordered to Berlin in late October. In November, Württemberg abandoned Kolberg, broke through the Russian lines to reunite with Platen, and then attempted to rout Rumyantsev from the rear. When Platen and Württemberg did not succeed, Platen departed as ordered, and Württemberg tried several times to force his way back into the fortress. On 12 December, the Russian forces halted his final attempt at Spie, southwest of Kolberg, inflicting 1,000 casualties on his force. Württemberg's remaining 8,000 troops thereupon retreated to Stettin.
