This has happened to me quite a few times and is really pissing me off. A huge AI force assaults one of fortresses with a defensive in the square. I throw a sizable army in anticipation of the AI assaulting it in that square for next turn.

The AI gets there next turn but only fights the squares defensive i put in, not the troops I sent to help it. THEN all of a sudden the forces I sent to help fight are locked up in the fortress being sieged!!

What gives?

How can I make the forces going to the province with the fortress actually assist the natural defensive and fight?
