(Vaguely related to What kind of equipment would a giant slayer use, but different premise enough)
In a somewhat Northern-mythology inspired setting, "viking" villages and cities huddle in fjords, different manners of monsters creep in caves and tribes of giants haunt the hills.
The most common kind of giant-kin are similar to fantasy ogre:
- 3.5m tall in average, up to 4m in exceptional cases.
- Significantly stronger than humans.
- Tribal stupid: can fashion a club, rudimentary shelter, but no boat or complex weapons (no bows, no forging, can scrap metal to a certain extent). Capable of simple strategy when raiding.
- Boar-like hide, hard to pierce/slash.
- May enslave smaller races and use them as cannon-fodder in combat.
I'm wondering what kind of weapons would humans use in this context to defend their settlement against such opponents. Some restrictions for answers:
- A hit and run strategy isn't viable, it's a fixed location defense.
- No "Van Helsing ballistae". It's a 8th/9th Scandinavian kind of technology setting.
- The defenders don't have access to potent poisons. No neurotoxic sap on your arrow. The best they can manage would be something that cause an infection.
- Pits and traps are doable, but you have to take into account, a full fledged raid will be something like two dozens ogres preceded by 50 human/near-human slaves.
This is a question about weaponry (blades, spears, axes and all that good stuff). If you want to back it up with a strategic explanation, that's fine, but please, no meddling with the parameters (the slaves won't turn on them, the cities won't go nomad, etc).
