You order the Army to continue forward into Parsia while posting emergency mobilization order for youths and middle-aged farmers above the usual age limit set during the re-organization.
859 AD, Mid-Autumn
About five thousand of additional troops are sent to Augas, while a report from the Army puts them in Asur Hills, skirmishing with numerous units of Parsian horsemen, plus some axemen who seem to be some tribesmen-turned-mercenaries hired by Parsians in desperation, as they were never seen fighitng alongside Parsians before.
859 AD, Late Autumn
The fresh troops joined with the Army, which then launched a siege against one of major Parsian city-keeps of Khosra.
859 AD, Winter
The Army was split, according to the report; most of it remains besieging Khosra, which puts fierce resistance, while most of cavalry is currently harassing Parsian farmlands, caravans and supply camps across the Parsian westlands.
859 AD, Midwinter
Your son Tvadar sends you a letter; you have become a grandfather of his son! Tvadar's wife Igven called him 'Dagan', after her great-grandfather who has allegedly slain three monstrous Trolls of the northlands with his bare hands.
A caravan from Gubta arrives!
3to6
Your merchants this time manage to obtain hefty profits for the Treasury from the selling and exchange of eastern luxuries and spices for Luathbas raw materials, ores and processed metals.
Speaking of Gubta, the caravan have brought their emissary with a translator, the same pair who negotiated the trade deal with you several years ago.
"My master, Duran Amhal Kuskus Lotusjoos, wishes express his joy to see you still ruling over Luathbas. He has come to inform you that The Emperor, blessed be his hallowed name, is very happy with the wealth of resources that the trade agreement have brought to our lands. Therefore, my master, on behalf of the Emperor, blessed be his hallowed name, is here to discuss your war with Parsia and possible military agreement and mayhaps alliance between Gubtas and Luathbasians." They discuss something amongst themselves.
"My master offers you, oh King of Luathbas, that Gubta will send your Army a mighty force of twenty war olifants, and if you never saw an olifant, it is a large beast of burden that has a long nose and two gleaming tusks and large ears that it uses to cool itself, but properly trained and incensed, a olifant tramples and crushes any and all who have the misfortune to stand in the beast's path. For this, The Emperor, blessed his hallowed name, asks you that you allow the Gubta to reclaim parts of the Parsian eastern and north-eastern lands, as they have been always the homelands of Gubta and we lost them in the last fifty years."
"Another offer would be of siege engines, as our travelers and agents have noticed that you, people of Luathbas, do not seem to be well educated in terms of siege warfare, and therefore we would send you masters of the craft along with ample amount of workers, who would construct stone throwers, wheeled towers, spear throwers and rolling rams so that your conquests of fortified cities would be easier. It would amount for about a thousand of skilled workers and teachers, and for that you would cede the two small provinces of eastern Parsia, Aylud and Mehora, to our Emperor, blessed be his hallowed name, as they were always lands of dispute between Parsia and Gubta."
"If you wish for more, then my Master is allowed to negotiate sending of ten thousand Gubta swordsmen and double number of Dhai skirmishers, who are skilled with their javelins just as skilled as an archer is with a bow. These men would help you garrison and occupy the cities and keeps of the Parsians, so that in case of rebellion, your Army wouldn't be too small to quell it. This would mean that we would also put pressure on Parsian eastern borders. But in exchange for this, The Emperor, blessed be his hallowed name, wants some land concessions; of the Parsian cities of Kwazid, Khamur, Omar, Arra, which are the major trade hubs of the east and south of Parsia, and the northeastern province of Quyat in its entirety, and the gold-rich mountains of Suvaz in the northwest. Furthermore you would also take part in destruction of the Maqash, the holiest of Parsian cities in the southwest, which was built on the ashes of the Vadaja Temple that our First Emperor, may his soul forever reign in Heavens, built in the lands of Parsians eleven centuries ago, and which was burnt to the ground and its inhabitants massacred by Parsians half that time ago."
"Those are proposals that my master is allowed to present to you in the name of The Emperor, blessed be his hallowed name, and if you do not wish for any help, do so and no offense shall be taken by my master nor by The Emperor, blessed be his hallowed name." After a brief amount of thinking, the advisor approaches you and leans in to whisper.
"We're not skilled of Parsian geography, my liege, but if we were to agree to all three proposals, I estimate that Gubta would end with half of Parsia, if not more, for themselves."
A) Agree to Olifants only, in exchange for the minor concessions.
B) Agree to Olifants and siege engines and engineers, giving Gubtas the lands they always wanted.
C) Agree to all three offered options, basically giving half of Parsia to the Gubtas in return for their help.
D) Politely reject all of the offered help, as your Army can win this war on its own.
