So, after about a season, the 7-10 goblins who hadn't become caught in cage traps were scattered around the map, standing within a few tiles of where they had killed defenseless pets. Tired of my dwarves spamming "cancels place item in tomb" messages even though I had forbidden everythign on the surface, I sent my militia out to kill the goblins one by one.
I had one fatality caused by a dwarf (luckily, the only one with a unique custom profession) running out to his opponent before the other 8. (The 10th member of the squad died... somehow... a while back.) The siege is finally over when I kill the last one. I remove the "stay the ass inside" command from everyone, reclaim everything on the surface, and everyone rushes out to grab everything.
Then three things happen in rapid succession.
1) The Human Caravan Arrives.
2) One of my original 7 (my herbalist/mechanic) gets a mood.
3) another siege comes.
This time, ALL the goblins are riding cave crocodiles and giant toads, and they have come with trolls. Should a siege come so soon after another one? The last siege was here for 2 seasons max, probably less than that.
I order everyone inside. They get inside. My mooded mechanic gets in there too. Not everyone does... I started the last siege with 80 dwarves. I lost 2-3 dwarves during the siege; one a soldier, one a hauler who I decided to send out there just in case, and one possibly not extant from the start of the siege. Now, though, I have 67 dwarves. I also lost my chief medical dwarf.
I've got a soldier in the hospital with a fairly minor wound. His arm is gashed open. Done by a goblin, who he and his friend prompltly kiled. But it's all sutured up, it's turned yello. He should be in the hospital, yes, but he should also be able to drink his damn booze. Every few seconds I get a "cancel give water: no water source" message, because due to poor planning I can't build an indoor well.
So, while the humans lie dead and their goods lie, not even fully unloaded, in my entrance hall (which I can't reach because I forgot to design an airlock for my depot), my miners begin digging to get to the first cavern. My "nurse" repeatedly sutures the patient, who is surely grimacing. And my mechanic? He builds a badass mechanism, made of three rock salt, three kinds of cloth, two rock salt blocks, and a gem. It's covered in pictures of plump helmets and the king of some dwarf civilization who took over 810 years ago. It's called "The [something absurd] Mothers."
And I'm positive the cyclops I have in a cage is laughing at me. I think I"ll let him out into my "naked goblins for slaughter" pen and see if my military can deal with him out of spite.
