The Legend of Tholtig in my sig ultimately ends in tragedy...
She dies alone of old age, her children and husband long since dead, and the mountainhome she fought for her entire life to defend is abandoned to her enemies.
Along with that, I once modded in giant spiders to lay siege to my fort. They were a bit too efficient, and annihilated my entire army, including my militia commander, in a single siege, trapping them in silk before dismembering them slowly.
To deal with them, I set up a cunning trap. My fort had two entrances, one right above the other. The lower one was reach by means of a ramp, and a retracting bridge covered that ramp so that when the lower entrance was sealed off by it, the upper entrance would be opened. More bridges in front and behind them allowed me to further control the position of enemies within my defenses.
I chained a pair of war bulls near the underground entrance, next to my trade depot. A drawbridge behind them would prevent anything from passing them into my fort. I planned to trap a squad of spiders between that bridge and the one that covered the entrance ramp, after which my marksdwarves would fire from fortifications in the walls.
That part of my plan worked. However, I had forgotten that I positioned a marksdwarf right on top of the retracted drawbridge to the trade depot - and she was carrying a baby, because I made sure all my female dwarves with children wielded crossbows to prevent them from getting in harm's way. When I reopened the trap, she fell into the trade depot, and the next wave of spiders swarmed her. She fought valiantly, but she and her child were torn apart before my military could shoot the rest of the spiders to death and retrieve her.
Her husband had been one of those who died in the original battle with the spiders.
