The wolves arrived spectacularly on the second night.
Not many people were scared of the wolves' annual attack which was similar to the offering ceremony.
Usually, as long as the walls remained standing, the number of casualties would be under control. The only time the number of casualties would increase was when the wolves arrived at the wooden barricades and started digging their way in or clawing at the walls. When that happened, shooting arrows from the top of the walls could not fend them off anymore because the villagers could not keep up with their speed of damage.
Then, the warriors would take the lead with a group of wandering hunters to slay the wolves at the most concentrated point. Only then could the villagers stop the wolves from overrunning the village.
