My first 40.10 fort had a siege right after the first year. 2 goblins and 8 elves. We're at war with the gobos, and they seem to have subdued a good deal of elven folk.
With only 23 Dwarves and no military training or equipment set up at all, i had little choice. I called everybody inside and locked the doors.
That's what i tried, at least. Then it came to my attention that Urist McDerp had dropped a single Prickle Berry Seed on one of my doors, forcing it open.
Dumping did not happen in time, and my cage traps only caught 6 of the invaders. I drafted 20 dwarves, and bloody slaughter ensued. With barely anybody armed, the invaders were nonetheless wrestled to the ground and killed.
However, the fort has sustained critical losses: 10 dwarves dead in the fight, another 8 injured and resting in beds. I have no skilled doctor and neither thread, nor cloth or soap.
With a pond in front of the fort, a couple buckets and a freshly drafted dabbling voodoo doctor, we shall see where this goes. To my amazement, we do NOT have tantrums happening just now.
Shortly after, the elven caravan arrived. To my dismay, recent versions seem to have changed their trade goods. They did not bring a single thread or cloth unit.
Unfortunate timing, really. I had just completed an order for large trap equipment - spiked balls, large serrated disks and axe blades were ready for deployment.
At least my legenday mechanic survived, and 1 of each important job (farmer, miner, mason, woodworker, smith) so i've got that going for me.
Lesson learned for this fort: next immigration wave will be put on military training immediatly. Hopefully i get an experienced fighter with them, to teach the weaklings.
