Simply put: You can't shatter retreat your way through being encircled/trapped. In EU3 (here I go again), a defeated army could only retreat into a province where there weren't enemy units sitting there waiting for it.
Surround the enemy. Win the battle. They're done. -That was the ideal, otherwise just follow them to the next province & wipe them. But you can't do it anymore. If they CAN retreat... if there is a path open for them, fine -- shatter 500 miles back to where it's 'safe'.
But if I've got the enemy surrounded, it's total lunacy that he can just 'retreat' his way right past us. Say I'm at war with the Pope, we have a big battle in Rome, and I beat his main army. Now I've got troops stationed all across the Italian peninsula, to the north... his only line of escape. Those guys should have nowhere to run. One last battle -- fight to the death? OK, fine. But this idea that they can just run right past us, over into France somewhere... seriously?
