Gather every villages that you want to hunt the boar with in between it and your town center (preferably closer to the town center). Then, send your scout cavalry to attack the boar. As soon as the animal begins to attack the scout, order him to flee behind the villagers, then command the villagers to shoot the boar. This saves valuable time and resources that would otherwise be wasted by building a mill beside the boar. It also makes the trip to the town center or mill much quicker. Another way to effectively hunt boar is to attack it with military units until it is low on health, then finishing it off with villagers. Note: Boars hunted with military units will not be worth meat.
