Croatian armies were in Graubenden in case any Seriban army try to use Italian lands. NAP with Serbia was over and Borna sended message to Serbian, Hungarian and Sicilian leaders, message in which he wrote they can't use Croatian teritory without permision anymore, but since there was "situation" he granted them few more weeks to use Croatian land. But then scout reported that Serbian army is in Aquileja after those few weeks.
So Borna declared war on Seriba.

Kristian, asemble everyone, every count, knight, soldier, everyone. I want to see Croatian ranks in order in 5 minutes.

Yes my lord


After 5 minutes Borna went out of his tent looked around, and steped up on some rock.He was watching his army proudly. Everyone was here. He saw his counts are first in lines and smiled to them. Kristian and Wolfrick were standing in front of everyone in center.

Listen to me my brothers. We are at war with Serbia as you already heard. They have violated Croatian soil, which isn't tolerated to anyone. We may not be able to defeat them, win war or anything like that. But I'm proud to be Croat and I would die for my country and I know all of you would. This time war isn't our fault, Croatia needs us and I want all of you to do your best in defending Croatian collors. Now prepare for moveout. We march to war.
