Ok, so there's this stairwell that goes down to the second layer of the caves, which is where I have my entire fortress. There was a goblin ambush, which killed 5-6 dwarfs before my military hammered at them some. For some reason they decided that instead of attacking some more or just retreating, they decided to stay in the stairwell and chill. I figured I'd just put a door at the bottom entrance of the stairwell and lock it since I did just fine without going to the surface. I could wait a while with starting my green glass industry.
Ta-dah! Worst case scenario happens! What is that scenario, you ask? Forgotten Beast? No. Another ambush? Nope. Siege? No. Titan? Not at all. Accidentally breaching the circus? I wish. What's that? Yes, that's right! Immigrants!
19 of them. I usually like getting more dwarfs since I could always make them generic workers and soldiers, but the quality of the timing on this is distilled crap.
I immediately put them into squads, give them the profession name "Cannon fodder" and tell them to attack the 4 goblins. Sure, they don't have any armor or weapons but surely 4 goblin jerks would be completely overrun by 19 dwarfs? Right? Especially when they're the only thing between them and the booze stockpile? Right?
No. There's still 2 goblins left. Hanging out and taking it easy in the stairwell. In a pile of dead dwarfs.
