Hi!
I've just recently found DF, and loving it so far. Got a nice (at least from my point of view) little fortress running (my first), around 220 dwarves atm, and everyone more or less happy.
However, I'm having a bit of trouble handling goblin sieges...
My first siege was a breeze, I sent out the one squad I had and they chopped the goblins to pieces.
The second was... not so fortunate. More goblins, meaner goblins, end of story: Some of my guys bit the dust before I could retreat and raise the bridge (got a moat to keep them out, thankfully). Then I just waited for the goblins to leave.
Come the third siege, I had a marksdwarf-squad trained, and simply put them at one end of the moat and let them kill goblins until they fled. Easy!
Fourth siege... now here's the problem. The goblins, apparently grown wise since last time, brought crossbowmen. Lots of crossbowmen (around 30-35 by my estimate). Against this, my marksdwarf-squad stood little chance, even though they were on a tower, behind fortifications. Had to pull them back after having lost half the squad (and the rest of them I had to haul back, they we're in a bad shape) while only managing to kill around 5 invaders.
I couldn't very well send out my melee-dwarfs neither, since the crossbow-goblins were accompanied by around 30 melee-goblins and 10ish trolls. So they wouldn't have lasted long.
So, now I'm yet again waiting. I got one of the goblin-squads to retreat though, so right now they're all lurking about half the map away. Regrouping or having a party, I don't really care as long as they leave me alone.
My question is, basically, is there any "textbook" way of dealing with large mobs of ranged enemies? Fortifications help I guess, but I noticed that when you're outnumbered 5:1 enough arrows tend to hit you to make it hurt.
Also, can you only have 4 squads of military (including fortress guard) at once? Would've liked to draft more dwarves to even the odds (since I have a pretty big population), but can't seem to create more squads?
And am I guessing right, that not completely killing off the invaders make them return faster (and stronger) than what would've been the case if I'd killed them all off?
Last (and least, completely unrelated): My mayor was "attending a meeting" with one of my more disgruntled dwarves (one that was married to one of my ex-marksdwarves) and I noticed that my mayor was unconscious. Not harmed in any other way, just unconscious. Does it happen that an angry (not tantruming) dwarf knocks someone out while that someone is trying to console them (I'm guessing that's what the mayor was doing)?
Grateful for any answers/suggestions to any of the above!
