The fortress "workedwasp" has fallen to a human siege. Supplies were running low so I had to make a move. I positioned my troops just beyond the caged entrance corridor and lowered the drawbridge. The humans leisurely strolled through all my traps, killed my troops effortlessly, and then killed everyone else. I really wasn't expecting them all to get past the cage traps. I thought at most 3 or 4 would only get through. I'll have to remember that for next time.
Human sieges are tricky. If their liaison previously has seen your traps, sieges will know they exist and happily bypass them. Apparently dismantling the trap and rebuilding it will reset this.
Speaking of human sieges, my 21 year old fortress 'Scarfences' is in lockdown due to a human siege. Since they know of my cage traps, i've resorted to locking them out while i build new traps.
Currently building two entrances, one that has 6 goblin shredders, and one for dumping the invaders in lava. Also making/gathering obsidian for a minor megaproject i got planned (gonna build a large ANDROID statue).
Speaking of Obsidian, i got so dissappointed when the steam lifted in my first cast, and i realized that obsidian is a dull grey color. I could have sworn it was supposed to be dark green....so i rawmodded it dark green
