Under siege..any strategies?

[Irishmafia2020]

I am in a similar position in my Bactria campaign with Chach. I Sally and slaughter the HA's. If they charge, your spear men will make their money, and if they don't, you will kill most of them with your superior archers (Subeshi's out range HA's anyway, and Archer spear men are dangerous to them in melee). All of your archers have more arrows than the HA's do anyway, so after they run out you will be able to pepper them with arrows for an extra 10 volleys. Put your archers in loose formation during the arrow exchange. Use flaming arrows to kill armored units. Use your general to attack their FM, and you might well kill him (with heavy bodyguard casualties). After you have used all of your arrows, attack their force with all of your units. Try to focus them in one area. Most likely they will charge you and you will surround and destroy their cavalry in melee. Use your family member to pin their FM while this fight is happening, or flank the enemy and charge their rear during the main battle. They will break, and retreat, and at least 1/2 of your forces will remain.

During my ongoing war with saka I have fought many battles with only 6 or 7 archer units (and a FM/General) and I have won all of them while weakening the Saka. The problem becomes not how to keep Chach or other cities, but rather how to fund a proper offensive force into their northern territories while fighting in Parthia, India, and against the Selucids...

I do suggest that you augment your regional forces with 3-4 units of Dahae riders, and Parthian spearmen as well. The riders can move from Alexandria Eschate (spelling) to Chach in one turn, and they are therefore a force that allows you to quickly reinforce any city in the region with cavalry/archers.
