So the second siege rolls in and this time the goblins bring quite the lot, about 10 Trolls, some Giant Toads and whatnot, accompanied by ~30 goblins.
No way my 6 Marksdwarves are beating them, so the drawbridge is pulled up and the marksdwarves start putting bolts into trolls and goblins that come too close to the entrance. Then they run out of ammo. Since they won't restock while defending a burrow, I make them civilians again to give them a break, then after a while put them back on duty. Sadly, they don't pick up any new bolts :/
After trying to force them to pick up ammo for some time, I just resign.
"Screw it, the siege won't last forever, back to training duty" and so my dwarves retreat from their positions.
Sadly, they still won't pickup any bolts for training, but so what.
Until I notice a dwarf standing on the walls in full uniform, casually pumping bolt after bolt into the trolls below. He runs out of ammo, but decides that it's best to go down to the ammo-storage, pickup a new set of iron bolts and start all over again. And again. And again.
WHAT MAGIC IS THIS??
His description reads "no activity", and it seems he doesn't need any food or drink at all.
Well, if "no activity" means effortlessly killing 3 trolls and fending off the siege all alone, all of my military dwarves can gladly loiter around.
