Ennemies fleeing in turn base would be terribly boring.
But he still could at least cry for help ... i believe those on roofs should be able to hear yelling goblin from the well (its in Bow range after all, how long is it now ... 18m?) ... they could join the combat, and call for help once again few of them die, since they realize by that time that you are stronger than you look ... then goblins from other roof (and possibly those on ground under Apothecary) should join ...
Well, in short ... i would not mind at all, if you had to gradually fight whole Willage.
The problem here would be those Ogres.
But i could imagine them not caring about puny Goblins ... theoreticaly, but you should have slightly harder rolls afterwards, to perusate them that you are not their enemy.
