Germany’s Hindenburg is the overall commander of the offensive. He and Ludendorff, his chief of staff, hope to capture Łódź and Warsaw and win another great victory over the Russians. But although the Germans and Austro-Hungarians are making gains, this round of fighting is less decisive. Whether because of more careful action by the Russians or the difficulty of fast movement on Poland’s poor roads, Hindenburg and Ludendorff are finding it impossible to surround or smash the Russians as they had at Tannenberg and the Masurian Lakes.
