Finally ! i didn't saw a goblin army since 0.40.01 !
Well, so much for an "army", but at least they came.
My fortress is ready for them, 2 entrances, both controlled by a bridge i can raise at any time, doubled wooden walls all over the place and on top fortifications all around.
I wait for them to come and climb my walls.
And i wait, and i wait and ... oh well, so much for a siege, they're not coming.
So i do what i always done in past version, i intentionally lower my defense, let's drop the bridge.
I station my marksdwarves on top of my walls, behind their fortifications
Ok, now with the bridge open and the big "it's open" sign, the goblins are finally coming, it reminds me a lot of pre-DF2014 when sieges were no challenge unless you sabotaged intentionally your defenses
I already avoided to make a moat as i guessed goblins wouldn't even try to swim and there was no moat filling tactic possible for the AI in DF2014 anyways
I order the raising of the bridge, when the goblins are in range, here the 1st bolt fly and miss target :
The bridge close my entrance just in time and i'm preparing for the enemy climbing the walls to get to my marksdwarves reloading ...
... but the goblins all run away in terror and exit the map.
Well, it was rather underwhelming, but it was only the 1st siege i got on that fort, so maybe it will get better soon , without intentionally opening my defenses i hope.
But at least goblins really can come in 40.08
