As the siege beings, the Balt-Rhein army is short on food supplies, causing Pineau to take a large platoon of soldiers to steal from the more vulnerable Turkish army. Wanting to avoid conflict, Halil and his army choose to maintain a two-day distance from the Imperial army, since the latter is mostly made of infantry. After successfully avoiding conflict for ten days, the Imperial army manages to catch up to them after Military Supervisor, Lily Kokoschka, intercepts their marching routes on the eleventh day and orders the army to use river rafts to close the distance gap. Knowing it is pointless to run, Halil and the Turkish army engage in battle with Balt-Rhein. Having fought against Halil in a war thirteen years ago, Pineau recognizes that Halil's tactics. As two Turkish divisions circle around the Imperial army's rear, they are quickly attacked with Ballista made by the 13th division, a unit of military engineers from the peerless iron-weapon makers, Röd Orm. With the rear covered by the 13th division, Pineau's army surrounds the Turkish army and kills Halil. Marching back to their base at Chielo victorious, the Imperial army parades Halil's severed head and beheads their prisoners, much to Mahmut's and the Chielo citizens's horror. As news spread about Halil's defeat, Zağanos stops the Divan from deploying more of their forces out to South Rumeliana and convinces them to let Mahmut handle the Imperial army, but promises to avenge Halil in the future. Meanwhile, a grieving Mahmut resolves to carry on Halil's will and continues his mission.
