9th GraniteNot only us and kobolds that find the undead difficult to deal with.
15th GraniteThe constant moaning of the undead beyond the walls have prove too much for Mafol, our secretive mechanic. Or perhaps we just didn't have any silk, either can push a dwarf over the edge, so he went berserk. A marksdwarf kept him subdued until a speardwarf came to take him out.
13th SlateThe production of bolts, crossbows and quivers has given The Defensive Flags enough equipment to take out the zombies harassing haulers in the south-west section. The convenient arrival of a herd of unicorns to the north has also reduced the amount of terror involved in further constructions, so an extra few levels on the north tower should be able to continue.
In other news, Alath Nubamzaneg and Mezbuth Idakath welcome their third child.
19th SlateAfter re-killing the same emu corpse three times, Zulban has concluded that there is probably a necromancer lurking around the southern section of the cliff.
13th FelsiteAn elven caravan has arrived to the north-west, atop the zombie cliffs. We have made a strategic decision to not attempt a rescue.
24th Felsite Attained a general familiarity with wild boar training methods. Ast the woodworker has tamed 9 wild boar which now run freely around the fortress. Once we have a breeding population, we will be able to vary our diet beyond strawberry biscuits.
26th FelsiteUrvad the Blacksmith went fey, claimed a forge.
11th HematiteAfter demanding we shear a llama for woolen cloth, Urvad made this:
15h GalenaAnd ambush! Curse th- oh, wait, they're fighting the zombies. Never mind, then. Although Microcline has taken it upon himself to shoot at one of the ambush parties from his vantage point on the wall.

(Microcline is on Z+1 of the brown walled tower, where he had been constructing a wall.)
19th GalenaThanks to the heroic efforts of our goblin friends, there are no longer any zombies outside the tower walls. There is one trapped in a section of the west tower that they couldn't get to, and a whole crapton in cages still.
A human caravan from Anthath has arrived in to the south-west, almost completely surrounded by goblins. I am still suspicious of the goblins motives for helping rid us of the zombie infestation, so I will keep the gates closed until the humans have negotiated safe passage through the goblin ambush parties.
21st GalenaIt appears their negotiations have failed.
End of Summer Report:Only three of the nine towers have been added to in the last six months, and that is unlikely to change until the end of the year. The important areas like mayoral offices, including an office for me, are nearing completion. Other non-essential projects, such as the hospital, have not been given much consideration.
The fort is sealed to the goblin ambush parties outside the gates. There are about three or four groups left. The mostly hang around the zombie cliffs, re-killing anything that gets raised out there.
While the weapons have been recovered and our bolt supply is good, building upwards, away from the goblins is a higher priority than killing them. We have not had any migrants attempt to reach the fortress this year, fortunately. Perhaps when we are better prepared to receive them they will return.
