Bethmann Hollweg wants a decisive victory in the east – perhaps he will get one? The Germans under Mackensen are at the gates of Łódź, hoping to surround and destroy one of the Russian armies in Poland. But the Russians have reacted with uncharacteristic vigour. They call off their offensive into German Silesia and force march troops to the vicinity of Łódź. They smash into the flanks of the German forces. The tables have been turned: now it is the Germans who are in danger of encirclement.
The weather is now afflicting each side as much as enemy action. Winter has arrived and at times the temperature drops as low as -12 Cº.
