I didn't think i would be saying this anytime soon, but THANK YOU WEREWOLVES! xD
The 4th siege on my fortress didn't end (i think its because a goblin leader or such was caught in a cage trap right outside my front door/drawbridge) and they got reinforced by a 5th Goblin siege, and shortly after, an Ilithid siege (that quickly got wiped out), that left, as far as i could count, roughly 50 Goblins/Ogres etc outside.
Having only Cobaltite, i smelted as much of it into bolts for my marksdwarfs, who sat on top of my tower taking potshots at the enemies if/when they came too close. I killed 5, maybe 6 of the enemy, but eventually, my arrow supply ran out, and with no wood to make charcoal, i ventured into the caverns, and taking some loses from various 'blind ogres' and 'Beholders' managed to keep a trickle of Cobalt arrows being produced.
Summer passed, Then Autumn, and in early winter, there came another siege of werewolves (alongside a Dragon Raptor), and i thought 'oh good, maybe they can thin a few Goblins and Ogres out for me. Turns out, the 15 or so werewolves and raptor obliterated most of the 50 Goblins/Ogres, with the survivers turning on their heel and fleeing. The werewolves, taking damage from fire attacks (my valley is on fire AGAIN, lol) also fled.
I love this game.
EDIT - Got an Ilithid ambush of 6, sent my archers, and some Hammerdwarfs to attack them, they were crossing my bridge when an Ilithid shot a fireball at it and destroyed it, sending everyone into the depths. Dammit xD
