When I was active I didn't like doing it this way. It took forever, and then one axe-blow killed the gobboes. If you leave them in their armor all the dorfs have to do is steal one weapon from each gobbo, and then when the mass execution happens the gobboes get protected by their armor, and can use their shield-user/dodger/etc. skills. the result is your military dwarves get more experience.
My method requires a very accurate inventory, so you better have a pretty good book-keeper. This is in addition to the active dump zone, of course.
First I claim all the stuff the gobboes are wearing. This uses d-b-c. Just tell it to claim the entire cage stockpile. When that's done you uses d-b-h to hide the the entire cage stockpile.
Then you go into stocks from your status screen, and go down to your weapons. Hit tab so instead of viewing a list of how many of each weapon you got, you're viewing the list of weapons. Go through and hit 'd' whenever you see a weapon with a blue 'H' by it. Then you un-hide the cage stockpile with d-b-H.
I actually found myself use hide and unhide a lot, because I really hated it when some stupid lump of rock was in the way of me seeing whether the loveable little twerps had dropped a chair when somebody decided to run from a cockroach or something.
Yeah, I noticed it too. Even dabbling axedwarves were lethal to naked gobbos and majority of them barely got to novice. Great...
And well, my fortress of Bluetower was struck with tragedy today. Everything started fairly normal. I got another migrant wave which put me at around 70 dwarves strong, and soon later I get another snatcher announcement. This time however that one snatcher stabbed a random migrant carpenter ( couldn't care less about him ) and shortly after he suffocated. The first death in my fort.
For some reason he didn't want to leave the map and he kept scaring other dwarves off, so the genius me decided: "Let the axedwarves deal with him and gain experience!" And so they were send to kill the snatched, clad in full steel equipment...
Then an ambush came. It was just a single gobbo, so I though he's just gonna fall into the cage trap. But then another ambush came. This one was FULL ARCHERS. Oh shitting and thinking I retreated my dwarves into the dining hall for their own safety.
Both fortunately and unfortunately, my 5 greenhorn axedwarves were still outside, but on the opposite side of my microcline tower. And then they discovered another ambush; This one had 2 axe lords. They quickly dispatched 3 of my 5 soldiers, leaving my axe commander to deal with them... Ah, did I mention they STILL HAD THEIR TRAINING AXES?
Yep. My DABBLING commander with WOODEN AXE was courageously taking on 3 axegobbos, 2 lords, the other dwarf was... just standing around. So after stationing him right next to the fight... he promptly got one-shotted.
The archers have been dispatched by human caravan guards ( Heh, 2nd human caravan that saves my bacon from gobbos ) and my poor axe commander is being constantly struck by those 3, unconscious, bleeding and pale. In exchange he's now a master axedwarf and I think he even got up to legendary fighter, just parrying blows until he kills one of the lords. I don't know how long will he last, and the help I send him ( my huntress, the one who slain the minotaur ) has been promptly gutted. If that dwarf survives the whole ordeal he's gonna be greeted with utmost dwarven honor... and no booze, since these slackers in burrows don't do anything and my stocks are dangerously close to single digit...
Another day in Bluetower, it seems...
