Hindenburg and Ludendorff are leading a combined German and Austro-Hungarian offensive into Poland. Thus far things have gone well, with much territory captured and great losses inflicted on the Russians. Now the attackers reach the Vistula river. They are only 19 kilometres from Warsaw. Hindenburg hopes to press on and drive the Russians out of Poland.
But the offensive is running out of steam. Hindenburg’s supply lines are now stretched. And although the Russians have suffered many casualties, the Tsar has a bottomless well of manpower to draw on and can make good any losses. Increasing numbers of Russian reinforcements are convincing the local commander, Nikolai Ruzsky, that he can block the enemy from making any further progress.
