Awright! Come test my automatic murdertrap, would you?

NO, YOU OBNOXIOUS LITTLE DUNG BEETLE, STAND ONE TILE TO THE SOUTH!
I'm pretty sure that forgotten beasts and titans are trapavoid and thus won't trigger pressure plates. Well, not directly. You can always trick them into setting off a water switch (costs you a door per job, because they never open, always destroy doors they come across).
War animals can be quite useful. In one fort, a dozen war dogs managed to lock down a war _jabberer_, a violent birdlike creature almost as large as an elephant. And those were the unfixed fort-born dogs, roughly the size of cavies. The constant nibbling from all sides overexerted the jabberer so badly that it kept passing out and never counterattacked until the military came over to finish it off.

Blamelesscloister, winter of 89, 29th year of the fort. We finally reached the watermark of 80 beards and promptly received no dwarven but rather a goblin caravan. They only had some second-hand clothing and equipment, but were charitable enough to give us everything for free.
I had save-scummed a mood that failed from me being distracted and only noticing the moody child was missing a single piece of raw green glass when six weeks had gone by. While i waited for the glassmaker to make the glass, the child went berserk, bringing us back down to 79. I was also kind of miffed by the human caravan getting scared away by a kobold ambush. With this cheaty knowledge, i went and locked everything up before the humans came and got them through the side corridor intact, albeit without wagons (humans with wagons are annoying anyway - tons of useless large clothes and take _forever_ to pack up, running the risk of a gridlock with the dwarfs). The child successfully made their giant pig bone toy hammer, as a possession. As revenge, the kobolds glitched their way inside the fort. I still have no idea how they do it, if there's some sort of one-way passage that cannot be used from within, only from the outside, or if they straightway spawn inside. Hopefully, the coming sieges will give a hint - with those, you get to see their spawn points. The swordbolds sneakily walked right into the eastern dining room and asked an eating farmer for directions to the artefact hoard and whether she was interested in acquiring some top-class face stabbings. As it turned out, the farmer was the marksdwarf squad leader, who promptly shot the leading kobold so hard it was hurled a few steps back by the impact. The rest of the squad was heartily welcomed by the instantly-scrambled melee troops and the nearby war grizzly contingent. Cue mauling and flying kobold parts.
The "siege" was the standard first open assault consisting of a few spear-carriers and a bowgobbo riding a giant olm. Not very exciting, mainly good to see the blow-by-blow account of how minecarts go about pulping goblins; it usually takes two to four pages of reports; every cart impact breaks something, but there are so many bones in a goblin that fatal hits take a while to occur. If a headcrush doesn't come up, it's either a mangled heart or suffocation, from crushed lungs or paralysis via destroyed spine. A ten-ton minecart is rather brutal in its effects: one hit jammed the _left_ false ribs through the _right_ true ribs. The primary minecart's at 142 kills now.
