Warning: Long boring rant aheadThis turned out to be a huge rant instead of a 'simple preventable mistake'.
I guess i just wanted to share the story of my fortress somewhere but i think it ended up a rather boring read =/My first fort after the major patch in april was in the .12 version (last week). I always tend to want my starting areas to have extremly high cliffs + mountains on one side, and a big flat grass/wood area on the other side. Found a perfect place! It even had a smaller mountain right infront of the cliffs of the big mountain and i realized i wanted my entrance inside that mountain with stairs up about 10 levels and then a bridge into the main mountain.
PICTURE:
But I knew it would take too much time to dig all of this out before i could start my food production etc. and I should probably do a 'workers hall' where my dwarves can live while i dig out the main fortress.
This turned out to take alot of time aswell and suddenly i had 25 new immigrants to take care of in a small mini-fortress designed for less than 10 dwarves. I always panic when i get 25 new dwarves and i tried getting an army going and all of this took my focus away from the soon to be epic main fortress.
I finally started digging out the entrance but the design ended up rather bad imo beacuse i was stressed a little and wanted the main fortress up and running so i could start exploring the new features of the patch.
Then BAM. 20+ more immigrants.. holy hell what do they all come from? and why are they even coming here?
Anyway I had gotten some parts of the main fortress up and running and the bridge between the mountain was built so the dwarves were running between the worker's area and the main fort all the time right out in the open.
This is when the first goblin ambush appears... DAMNIT IM SCREWED. I had like 4 dwarves with training weapons.
Being new to the military system and having only 2 cage traps i sent my tiny squad straight into battle. They decided to do the "one-at-a-time" strategy where three of them wait in the fortress while the first run to take on the assault alone. "They'll never expect that!"
He actually got legendary fighter.. seconds before dying..
Managed to fend of the ambush with the usual emergency-tactic.. swarming them with the whole fortress... (I've killed dragons with it =P. which is a rather cool story itself)
about 10 dwarves died, aparently good friends to some people, who thought that clearly the only way to deal with the situation was to go insane, destroy the chairs and tables in my dining room and beating other dwarves to death before getting killed themselves, leaving their children depressed, who then dies of thirst...
You know... the classic Tantrum Spiral™ has begun.
After some time i had only the last migration wave was alive, with a few of the old dwarves unconcious in the hospital beds.
Aparently the newest dwarves didn't care about the rest of the fortress dwarves since they were just 'content' with the whole thing. I guess they hadn't made any real friends yet.
Now i thought i really had to move in to the main fortress and get some defenses up before...... another ambush occurs. GOT DAMNIT!
no military, no cage traps... screw it I'll swarm them right of the bat. I guess the 7-ish goblins really didn't see it coming when about 20 civilian dwarves ran out from the cave launching fearlessly at the ambush because NONE of my dwarves died and all except one goblin was slaughtered. The swarming tactic worked better than i expected.
Ok now it's REALLY time to move in to the main-fortress. destroyed all buildings and stockpiles in the old fortress and moved in everything, got about 7 military dwarves and some new cage traps in the new entrance...
Another immigration wave with 23 dwarves arrive and shortly after a new ambush. This time i thought i had enough military. Sent them all out and watched them get butchered and not killing any goblin... WTF?? ok so now there's only about 40 dwarves left in the fortress.. SWARM!! ... .. BLOODBATH... i guess they learned my tactic. There was now about 60 dwarven corpses outside my entrance..
The goblins then gleefully entered the hospital in the old fortress and butchered the unconcious dwarves that barely survived the earlier attacks..
All i had left was 2 children and 102348 animals crowded into one single dining hall, waiting for a report from the surface.
Abandoned fortress when the whole goblin squad except 2 were caught in cage traps (i guess the leader got caught cause the other 2 just stood there, killing kittens who dared entered the fortress)
Sooooooo my mistake could have been prevented by alot of things:
-Alot more cage traps in the worker fortress entrance.
-Alot more anything in the worker fortress entrance
-Skipping the whole worker fortress all in all and just dig the main fortress right of the bat, ignoring the entrance-mountain (there were ramps everywhere so nothing stopped them from climbing the cliffside)
-Waiting for the goblins to get caught in cage traps instead of sending the whole fortress out to fight them...
It hurt to abandon the fortress cause i knew it would be so hard to find a similar area again.
