You might be able to set a strategic "combat posture" for your nation overall, and a "standing order" for each stack. Otherwise, when you have an encounter, the game can stop and prompt you "You have X troops encountering a stack of Y enemies. What do you wish to do?" -- and you can choose different strategies like "hold," "withdraw," "fighting retreat," "probe," "outflank," etc. If both hold or withdraw, etc., then no one fights.
The thing I also want to do is allow weaker forces to withdraw into defensive fortifications. There's no reason that a large city couldn't accommodate a significant force. The attrition might be wretched, unless you had an open (unblockaded) port, which might moderate the attrition somewhat.
Then, you could use the above strategies to "sally forth" -- especially using a "probe," to make some tactical victories against a besieging power.
You might also have some sort of system that looks at the terrain -- forests, mountains, deserts, marshes, etc. -- and likewise allows more "guerilla"-style combat... Trying to avoid open battles, but letting gritty and determines leaders pick away at a bigger army through a series of skirmishes.
I just feel that there's been a significant absence of defensive options for smaller nations. The current strategy of "well, I guess I have to get my ass kicked in an open field battle... again" isn't much of a fun one for a small power. Why even build your 2-4 regiments if that's all that's going to happen?
