A red dragon killed everyone.
Steel clad military dwarves charged in only to be cut down like wheat by what I imagine was the almighty god-king of dragons.
Once the military were dead, I started panicking and sending drafted haulers at it, to no avail. In a final rush, I sent every able bodied dwarf at it, and somehow, this greatly wounded it, giving it about 6 red body parts and 4 yellow, as well as taking a talon off, but it killed every single dwarf in the process.
There was one left, a miner, one of the original seven, who was so far under the surface that he hadn't made it to the fight, but he wasn't going to let him charge to suicide. I stopped the command, and I made him grab some of the armour which was laying around, but there were no weapons left that were accessible, so I made him smith his own sun gold sword. It came out as a +sun gold short sword+, which was surprising, given his novice status (He had been trained with weaponsmithing previously, though I don't know where.)
He equipped it, and with a heavy heart, I gave the order to attack the dragon. It was a pretty good fort, this one. I'd have liked to continue it a little longer, I thought to myself. He approached the hospital (The dragon had been hanging there. Maybe he needed somebody to attend to his wounds?) and the dragon caught sight of him. He took a blast of dragonfire without injury, and then they proceed to fight for about 20 rounds (Dude was a steel dwarf, and he'd been trained for a while in the early days of the fort, before a full time military was created. He was pretty tough, although not compared to the military who had been summarily slaughtered about a week ago. He got a heck of a lot of red wounds, and I was already beginning to think of what the next fort would be, when I see the most shocking message in my life.
"The swordsdwarf hacks at the dragons upper body with the +sun gold short sword+, and the severed part sails off in an arc!"
Celebration occured, though it was short lived as he suffocated in the next few frames. I like to imagine he was screaming the name of the fort as he struck the final blow. Although it would have sounded quite silly, the fort being named "Paintdays" and all.
Rest in peace, Sarvesh Zonstukon. You were too great for this world.
