The Serbians, as the Bosnian Army marches into their nation, are not so pleased by their neighbor's invasion, and are further threatened by their proximity to Belgrade. Serbia rejects the ultimatum, claiming that the Bosnians could have simply requested a union with them, and they would have accepted. At first, the Serbians would have some trouble breaching Bosnian defenses, but eventually, with reinforcements from Skopje and Nis, the Serbs would begin clashing with the Bosnians, and for the walls, the amount of time it would take to set up such a large chain of walls would be abysmal, allowing the Serb Forces to launch a few counter offensives against the Bosnian Army. The Serbian Army will have reached about 120,000 Active Manpower, and as for the air, the Serbian Air Force will have mobilized, and will have begun attempts at securing Air Superiority over the skies of Serbia. Eventually, major clashing would occur around the Belgrade City Area, where 35,000 Serbian Troops would make an attempt to retake their capital, while forming a Provisional Capital in Nis. The Serbian Provisional Government is also formed, and said government refuses to surrender 'under any circumstance' as said by the government.
