So my fort just had its first goblin siege, so I ordered my military(4 squads of ~10) to stand outside of the front of my fort, but still inside my walls.
I had a lever that pulled up the four drawbridges that lead into my fort. I really wanted to pull it, but this was happening at the same time the dwarven caravan arrived.(They also came with a liaison to inform me that they want my fort to be a barony!)
The goblins arrived before the first caravan had arrived at my trade depot, which required crossing one of the bridges. I was watched intently, looking between the caravans, which were going painfully slow to my depot, and the goblins, which were going painfully slow to my fort. Soon, the last caravan was juust about to fully cross the bridge. Just one tile. I ordered that lever pulled and also made my citizen burrow go up to it.
I watched my woodcutter go up and pull the lever, but at the same time I heard Soundsense start playing battle sounds.
My dwarves and the goblin squad were both on the bridge.
It was too late to get that lever pulled and I watched in horror as the bridge went up. The scream that Soundsense produced, indicating one of my dwarves was killed. I paused the game to assess the damage. About 3 dwarves were knocked on their ass by the drawbridge slamming into their face, otherwise unharmed. One dwarf was propelled into the my moat with enough force to kill him. Another 3 dwarves, including my captain of the guard who I had named after a friend, were in the moat, along with 5 goblins. The rest of the goblins were on the other side of the bridge, a few of them inside my strategically placed cage traps. I unpaused the game to see how this would unfold. I doubted the survival of my poor friend in the moat, as the only way out was on the opposite side of the moat, behind a closed floodgate. The goblins and the dwarves started fighting while underwater and drowning. I was truly an inspiring sight, until they drowned a few moments later. (Luckily, they had managed to take out at least one of the goblins!)
That was the end of the remarkable things. I had my broker trade with the caravan, my citizens haul the newly aquired goods, got my mayor recommended for barony. The drawbridge was dropped after that and the goblins came back over the bridge, only for three of them to get slaughtered while the rest fell into my cage traps. Then one of the caravans' escorts tore off a coati's toe with his teeth.
