Defending a castled province without patrolling?

[Boron]

How to do this?

If I don't want to patrol due to pop loss, or by another reason, how can I defend the province, assumed there's a castle in the province itself?

hm i have a idea :
build a garrison for each caste and move them to the other castle . iirc there is a order move + patrol . this way when they are moved each turn they shouldn't patrol but defend the castle .

there'll only be pop loss if there is unrest. unrest is reduced through lowered taxation before it is through patrolling, i believe, so lower the tax rate and you should be fine, unless you have very high levels of unrest.

and if your tax rate is already 0, for instance because it is a bloodhunting province, well then, just suck it up and either patrol or don't.
