You return to besiege Khosra.
867 AD, Midsummer
A messenger arrives from Luathbas; your dearest wife have given birth to another daughter of yours. She named her Lynda.
Few days later your horsemen meet and defeat a small unit of Parsian Cataphracts. The armored Parsian horsemen couldn't win against Luathabs light horsemen numbering five times their own.
867 AD, Late Summer
As your Army prepares to hear the news of surrender of Khosra (as reports begin to leak outside about dire state of the garrison and the populace), a messenger arrives from Governor of Lauthbas.
"My liege! Parsians have moved through the mountains and are attacking Luathbas!"
"Surely the valley into Parsia was guarded by our outposts?" Asks one of commanders, but the messenger shakes his head.
"Nay! I said, through the mountains! These savage bearded axemen, masters of mountains, have led Parsian troops and commanders around the peaks, which must've taken them at least a month of time. That our scouts haven't seen them till the Parsians established camp, is pure bad luck! The governor's militia dealt them a small defeat but the Parsians are strong in numbers while Augasians are no match for them."
The commanders hold emergency council and many ideas are cast. Finall, it is time to decide...
A) Abandon the siege and march westwards to Augas in hurry to meet with the Parsians and defeat them before they do any damage.
B) Split the Army half-half and then go back to Luathbas while siege of Khosra shall continue.
C) Send horsemen to Augas while rest of the Army shall march to Parsia to capture the capital and win the day!
D) Leave a small detachment of people to maintain the siege while rest shall go and battle PArsians in Augas.
E) Negotiate with the garrison and popualce of Khosra to at least solve this issue for now.
