The Russian counterattack at Rovno has dealt a heavy blow to the Austro-Hungarians. Despite the defeats they have endured over the summer, mainly at the hands of the Germans, the Russians show that they are still a force to be reckoned with. The Austro-Hungarians suffer perhaps as many as 300,000 in the Russian counter-attack, but now the Germans come to their aid, striking at the Russians and recapturing the Ukrainian town of Lutsk. This effectively puts an end to the Russian counter-offensive.
The Eastern Front begins to stabilise. Mutual exhaustion and the worsening weather are making offensive operations increasingly difficult.
