Your troops start the flanking maneuver, trying to get behind the goblins.  The goblins are creeping or running, trying to use the trees as cover, because they're getting shot in the back.  You find that the rangers Cheerwind had warned with her bird, have been getting into position and used your attack as a diversion to start their own attack.  They're rapidly clearing the remaining goblins and traps out of the forest.<br/><br/>(The area doesn't have Jujapu trees.  There's no blasting powder.  Gobinoids couldn't afford the ingredients.  Fairies have limited invisibility so Cheerwind can scout safely, but the effect dispels if she attacks, so she'd be visible with her match in the middle of the enemy.  Your call Cheerwind.)
