Russia is still reeling from Germany’s offensives in the east. The Germans are advancing into Lithuania and have taken the town of Szawle. But they are also advancing into Poland, with one army marching towards Warsaw from the north and another combined force of Germans and Austro-Hungarians threatening it from the south.
The southern force, under Field Marshal Mackensen, lays siege to the fortified town of Ivangorod. As Ivangorod lies to the south east of Warsaw it now looks like nothing but a miracle will allow the Russians to hold onto the Polish capital.
