So I had the wonderful idea of training my military dwarfs at swimming. I am in a terrifying beach, so I thinked it would be useful. But of course, at the same time two zombie whales were breaking in my fortress, going into an rampage and killing dwarfs quickly. So I sended my military, and then every thing failed in my life.
The whales basically did a massacre. Any soldier that was not dead at that moment was in coma for is whole life. And at the same times... Ogres. Three. Near of my fortress. They entered, passed the last whale alive (she was about to die anyway) and started another killing spree. The population of my fortress had dropped from 134 to 116 because of the whales, and now the ogres were just having fun with my civilians.
But of course, I had a plan. All the defenses of my fortress were down, the ten military dwarves were dead, I had ogres killing the cook in the dining room and zombie beasts could enter in my fortress (at this point, there was a little army against me, because I had never tried to make the zombie population outside of my fortress decrease) but I had a goddamn epic plan.
All the 103 dwarfs still alive retreated into the deepest part of my fortress. I was doing a little challenge in this fortress and all my dwarfs were trained to fight, a little bit. But of course I had no equipment for them. So deep in my fortress, near the tree farm, i cutted all the trees of the underground and built a carpenter workshop to build wooden armors and shields, as much as possible, while the bad guys in the top were breaking doors and statues, getting near... I digged out after that some of the obsidian layer of my map and then built obsidian shortswords. At the end, half of the dwarfs were equipped with all this scrap before the ogres finally breaked in. And the massacre started again.
Killing, killing and killing. Dorfs flying across the room. The mayor getting owned by a zombie kraken and bleeding to death. The new milita commander, the only one with steel armor and weapons, got destroyed by a zombie tiger. But at the end, I won. 34 dorfs were still alive and nearly nothing else was living on the map. They returned up in the higher levels, reconstructed the doors, rebuilded the defenses, and the fortress started to live again. And then...
Forgotten Beast McWeirdName come in the fortress. It is a giant bear of fire, capable killing dwarfs with his venom.
