You agree to the terms - a month respite from warfare, or more if Caius successfully pushes your agenda amongst the Senators.
1217 AD, Winter
A week later, the Damdamian army (including the garrison of captured Evalian capital) has retreated to Rucus, where it was supplanted by another five thousand troops. Spies inform you that at least five thousand more are camped at Republican-Rucusian border.
Not wasting any time, you call in reinforcements from local cities, whcih amounts to a thousand of lightly armored auxiliaries and guards. The eight-thousand strong Helliste force also joins your main Army.
You also pick up on news from the Palace:
Apparently, there has been lots of discontent and quarrels between noblemen and commoners in the recent weeks, especially in former Cydwyl. There have been few cases where peasants accused nobles of treachery, leading to imprisonments and killings. This internal strife has caused unhappiness in the Empire.
Also, your distant aunt, Aurelia, wife of Deathan, has passed away after a short illness that she caught during recent, cold, windy days.
Two weeks afterwards, the scouts from the borderlands bring news - the Damdamian army's numbers have exceeded thirty five thousand (compared to yours twenty eight right now), replenishing its cavalry units, and is again on the move! In a short time, they will cross Rucusian border and once more invade the Duchy of Eval. Caius Cuscus is not in command; someone else is leading the troops, and your spies are still gathering information.
During a council with your officers, you decide to...
A) Immediately move for the border, to fight Damdamians right after they cross the borders.
B) Wait few more days to gather more information on the new Damdamian leader and whereabouts of Caius Cuscus.
C) Wait a while to gather more information and let extra reinforcements from around the Empire to join your Army.
