Just had one of those perfect moments that I felt needed to be shared.
The fort is Shootbinds, ten years old and with a well-developed elite military. The dwarves of Shootbinds are a bunch of paranoid survivalists, so the fort's entrance is a bit of a bunker; there's a drawbridge that leads to a small courtyard, an entrance hall, then trade depot, a pair of double doors, and then a large barracks. Anyway, a bronze colossus showed up so I sounded the alarm and called everyone in while mustering my military in the barracks. To give myself a bit more time to prepare I ordered the drawbridge closed as soon as I'd confirmed everyone was inside. It slams shut. My troops begin gathering. This is actually my second colossus attack in this fort and the first one was a near disaster, so I'm bringing in all my big guns and loading them for bear.
Suddenly, Snatcher! Protect the children! The poor doomed bastard lost his stealth right in the middle of the barracks - he must have just got in before the drawbridge went up, there's absolutely no way out of the fort. Immediately adjacent to his tile were two champion hammerdwarves, two axe lords, and one speardwarf, all in full steel. One of the hammerdwarves winds up and lets fly. Purely by coincidence, a furnace operator just happened to be coming in through the double doors to the trade depot at that exact moment. The snatcher's body went hurtling over the furnace operator's head, through the trade depot, down the entrance hall, and finally skidded to a stop right in the middle of the courtyard.
Couldn't have planned it better. Good thing the furnace operator was quick to duck.
