The Russian Army had been bordering the Vistula on its length, holding three bridgeheads on the German side. On the 12th of January, Marshal Koniev unleashed his first Ukrainian Front and cleared the German lines of defense. At mid-day, the first and second lines were breached and Koniev had seized his main axis of penetration. He immediately ordered the introduction of his tank units to exploit the gap in the German lines. The Germans tried a desperate action and immediately counterattacked the lead Soviet units.
