As the Mongols close in, they attempt to exploit any weaknesses in the shield wall with their heavy cavalry. However, the Vikings are adept at forming a "hogback" with their shields at the rear, protecting against encirclement. The battle hangs in the balance, with both sides taking heavy losses. A group of Viking warriors, led by a chieftain, manages to break through the Mongol lines and targets their command structure. If they can take out the Mongol leaders, it could create confusion and disarray among the horde.
