Had a horrible dream last night; I had made a fortress so convoluted, caravans couldn't make it to the depot before they embarked on their journey again.
So, in my fortress, the caravan just arrived far to the south in the mountains. The cobalds brought with them a mountain wyvern, grizzly bear, and some eagles.
And the brutemen just sent another siege. So much fun to be had!
[Edit:]
Oh the dwarfanity!
There's blood and ashes everywhere! the militia is all but dead, and a dozen or more dwarves burned to death in the fires that spontaneously erupted from the dragons/some kid who likes to throw fireballs who also died.
The siege made it inside through an unfortunate gap in the defenses. I had thought I'd sealed everything in, but by the time I'd relaized it, it was too late. The dwarven caravan, which had also been trying to enter through this area, was the first to be hit. While viewing the location of the combat reports I spotted them; my marksdwarves on a nearby tower had already opened fire, as had the lesser dragon down in the meeting hall. With the hall up in flames (everyone had evacuated already besides the brutemen pouring in and the dragon/caravan gaurds.) I ordered the troops to station outside, to hold the door. The fire, it turns out, didn't like the wooden door I had installed for whatever reason, and soon the courtyard was up in flames and I ordered the troops to move. They did; right into a gap between the fire and pond, which closed to surroudn about 3 of them before they could loop aroudn the other way. All hell broke loose after that. The mage-kid burned to death in the fire he/she helped start (Did qutie some damage before the end, though.) and the militia was torn to shreds by the maceman squads and their mounts.
I stationed them in the beast training zone, where those not already engaged (and dead) and the untrained beasts could hold out. It worked well enough; once the enemy had come in sight of them and the next fight had commenced, the grizzly bears and yeric wyverns joined the fray, and the tide was eventually turned. They quite literally had the run of the place: civilians were dying left, right and center, and all I could do was order some of them into the dining hall and have some miners channel away the floor and remove the ramps, sealing them inside. A pair of recruits with ☼steel battle axes☼ engaged mounted brutmen in the farms, one of them entering a martial trance. They kicked ass, honestly, but I guarantee they're dead now. I have 10 out of 30 militia dwarves remaining, and some of them probably won't make it/may never walk again. That dragon and the majority of the wyverns and bears went down, too.
The brutemen are in retreat now. Lost a lot of good dwarves today. Once the brutemen have fully retreated, I'll have someone wall off that breach. And pray the tigermen/goblins didn't also send ambushes...
