That does look tragic!
Gave me an idea though. My forts succumb to enemy often the same way. It’s usually not dwarfs… Couldn’t I use pressure plates, laying around narrow tunnels and connected to iron bars, at those tunnels, to “quarantine” the whole fort? The plates would be set to “heavier than dwarf” and it would usually trigger the fort wide quarantine 🤔
I am really looking forward to that siege update. Wonder what will change.
