Despite their superior numbers, the Balt-Rhein army is boxed in by the Anti-Imperial Alliance and burns their rafts with fire arrows. Pineau orders his commanders to deal with their enemies that encircled them from the outside as the rest deals with the Turkish army that they have in an envelopment. Having chosen the battlefield beforehand, the Anti-Imperial Alliance has molded the area to their advantage and quickly overwhelms the Imperial army. After the El Toro mercenaries takes out the 13th division's ballista, Mahmut and his army escape the encirclement to take on the more vulnerable troops, decimating two imperial divisions. Seeing their disadvantage, Pineau withdraws his army and chooses to march to Espada, hoping to use it as a base for retreat. Meanwhile, Kyros and the others still search for the imprisoned Carvajal while stopping the rebels' coup d etat, and notice the Allies' signal flares confirming their victory at Murmullo basin. As the Imperial army march through the forest, morale continues to falter among them, especially as the Turkish army kills more of their men in their pursuit. Once at Espada, they discover that the republic is being guarded by the Lince mercenaries, who is being employed by the Cuore Alliance, thus invading the city means making an enemy out of them alongside the Anti-Imperial Alliance. As Mahmut's army arrives at their rear, he offers them a chance to surrender, but Lily surmises that the Lince mercenaries only has small force in Espada and their numbers is enough to take on the Turks. Hearing this, Pineau declares the army will fight and orders the Imperial army to launch a counterattack.
