Playing orc mod. Fortress doing moderately well - 50 dwarfs (capped at 40, but last wave of migrants put me at 50). Chasm, bottomless pit and a nice river thru middle. Little wood, no coal, no magma - so my soldiers aren't wearing much. Caravans (except elves of course) have been getting mauled by Orcs, so not much outside resources to help. Still, I've got around 4 Elites as standing guard and about 15 regular dwarves have done some time and are my reserve force.
Orc invasion arrives - around 48 Orcs total in 2 or 3 groups. I see our only kitty running *outside* with some remains as Orcs approach main gate. It realizes it's in deep shit, drops remains and runs back to gate. Should I pull the lever and lock kitty outside??? I decide "I can time it just right and save kitty, but keep out Orcs".
Wrong! 6 Orcs make it inside, including Soshoram the Hammer Lord. All but one of them are wearing lots of iron or steel armor. As soon as Soshoram gets inside, he blasts the kitty across the room with hammer. Call in my Elites! Oops. They're at the far northern gate (where I make dashes out to gather wood). That's very far away - 130 squares. I look around main entrance and see 6 of my ex-Military dwarves with some training. I activate them all and hope for the best. The hammerlord splatters them all over the walls. OK - now I activate everyone and rush them to the entrance. After a short time, the sheer weight of numbers brings down the Orcs, but the casualties are horrendous - 24 dead. Also, 4 wardogs died in the blink of an eye.
Then the tantrums begin. Endless tantrums, doors, tables, chairs, beds, even farming plots get destroyed. The dead bodies? Everyones too busy to bury them, the upcoming miasma storm should make everyone even happier.
Of 26 survivors, 7 are wounded (only 1 seriously). None of the wounded care much, they stay relatively quiet in their beds screaming for water and food which the others occasionally get around to. Of the rest, 4 have gone stark raving mad and 2 have gone into melancholy so that's six walking corpses.
A mother wend mad, and apparently the father picked up the baby after she dropped it. He went to the zoo and chucked the baby against the wall. Baby is now crawling around the decaying bodies in the main room.
The tantrums tailed off a bit, but the main room is full of rotting corpses - can barely see anything thru the waves of miasma. 5 corpses got hauled to burial ground and 4 corpses got put into coffins - and of course the precious kitty got one of them!
