Six years later, Songi is married and has two children but she still dreams of Kim Jun.

The Mongols attack the Cheolju Fortress. Even though the fortress has barely 2.5k men, they are able to withstand the attack of the enemy for a little over ten days. Generals Yi Won Jeung and Yi Hui Jeok, lock their families, and those of the soldiers, in a storeroom and burn it down. One of the generals gives Kim Joon his last order: go back to the capital city and report all he has seen on the front lines. The remaining soldiers of the Cheolju fortress open the gates and attack the Mongols.

Sartai admits he has underestimated the Goryeo soldiers because the Hansijin fortress was defeated so easily. General Kim and Kim Joon plan and execute a 12 men suicide mission to lower the moral of the Mongol troops.
