I checked this option to see how if would affect the game mechanics and disabled it after only two turns! My experience with this option has been bad and I would like to confirm one thing: this option will make my forces retreat in the face of a numerically superior enemy NO MATTER if my force is inside or outside structure in a given region, rgiht? In my game Huger left Fairfax region because some big Union force entered the region, but ALSO Longstreet left Alexandria without a fight !!!!! I thought that only stacks outside structres will automatically retreat while your smaller stacks inside cities will hold and wait for some reinforcements.
So, does this option move ALL your inferior stacks from a region?
Thx
