well, we were busy so we mostly let those sieges go without too much of a fuss.
next season however...3 sieges showed up together giving me about 200 goobos/centaurs
due to a kobold ambush our trap system was foiled(a locked door is crucial to sealing the fortress from the cage traps and should probably be replaced by a drawbridge)
this meant that my 4 legendary speardwarves, 3 marksdwarves, and 5 swordsdwarves(who suck) would be fighting about 150 assorted troops of which more than 1/3 were archers. Also, because of the way we were fighting, my own marksdwarves were unable to fire bolts and were in close combat the whole time
I was pretty sure that I was fucked.
Casualties:
3 swordsdwarves
2 marksdwarves
0 speardwarves
5 assorted civilians (some of the cooler civies started beating up goblins with their bare hands [more like bear hands, amirite])
160 enemies(when the four speardwarves were mopping up I lowered the drawbridge which allowed the few remaining centaurs to come in and have some fun)
once the mess had been somewhat cleaned up I threw my 60 prisoners that had been accumulating into the volcano(plus some baby alpacas, because I thought it was funny)
enemy civs are running out of leaders. What should I do with the corpse of the centaur war leader. Magma is too good for it.
I think I'm going to break into hell and build a shrine, then start dumping garbage/prisoners/adorable animals into the eerie pits
sadly, there is no cotton candy on this map so used DF hack to build a passage that I can get to by mining. Since this is a nano fort I may have issues with constant spawning of demons...
