Cryptdagger just finished up another goblin siege. A sense of doom accompanied this attack.
A kobold thief was discovered at the postern gate and the resident axe lord chased it out into the eastern part of the embark. At this point the human caravan arrived. (And I immediately thought "Oh crap - the goblins are going to appear and this solo dwarf is going to kamikaze attack a full goblin squad. So may it be written. So may it be done.)
Immediately afterwards - A vile force of darkness has arrived.
Four squads of mounted goblins and three squads of support monsters (trolls, giant moles, and giant olms).
The lone axe lord encased in steel promptly charges into a squad of lashers and a squad of trolls. Thirteen pages of combat log later the axe lord is dead, an elk bird has lost a foot, and the goblins have two Master Lashers in their force. (The entire first seven pages is the dwarf dodging attacks, blocking attacks, and getting bowled over by attacking mounts - and the one counterstrike on the Elk Bird. Eventually a lucky shot gets the hand holding the battle axe. Followed quickly by a second getting the shield arm. Then it is six more pages of lashers and mounts slowly tearing the dwarf to bits despite the steel armor until a flail shot to the head finishes it.
The siege then proceeds to get hung up in the access tunnels and mangled by weapon traps, a spike pit, and a squad of marksdwarves behind fortifications. And the human diplomat decided to walk out of the tunnel right into the middle of the goblin attack and get killed.
At this point military preparedness is going to get greater emphasis. Training schedules will be increased, and more citizens added to the militia squads. The fortress is pretty stable, so it should be able to concentrate on producing better troops for the kingdom.
And in other tunnels an experiment with minecarts produced the first successful "shotgun" launch of a load of stone blocks...
