Bribe them or if you want to kill them desperately, position multiple cavalry stacks to block their escape routes and have your men chase them in shifts. Position a second stack near where they generally retreat to.

If I recall correctly, if you surround the 9 (eight...) tiles around the enemy and then attack, they will have nowhere to retreat and will all die.

Someone correct me if I'm wrong.

That seems like an inordinate amount of work for two cavalry units. You're probably better cutting them off with two armies.

Also, your method works better for agents, since they don't have AoCs.

Attack them with a force that is equal in strength. Baktria's bodyguard units are pretty strong, so even one unit is probably quite a bit stronger than them. Try attacking with 2 similar cavalry units.

I really don't have the cash to bribe them and have only one general unit I can spare for the task along with the three garrison units. My one and only army is literaly years away. If I use the other general Baktria wont have a gov and I'll lose too much per turn, more than the forty hes costing me. I guess I'll just have to wait for another gen to come and try to pinch him. It is an awful lot of work for two units.

[miotas]

You could try just using those 3 garrison units without the general.

Why don't you just have them to retreat to your border? Rebel buffer stacks are nice when it comes to slowing down an AI invasion.
