The Battle of Łódź took place from 11 November to 6 December 1914, near the city of Łódź in Poland. It was fought between the German Ninth Army and the Russian First, Second, and Fifth Armies, in harsh winter conditions. The Germans redeployed their Ninth Army around Thorn, so as to threaten the Russian northern flank, following German reversals after the Battle of the Vistula River. The German objective was to prevent an invasion of Germany, and thus considered a success, though narrowly avoiding disaster.
