I start a new fort in an area where the only metal is Gold and Aluminum. Which I'm fine with as there's magma so I have my defenses covered. What I don't have are any early weapons. It's partially an evil biome so even without a strong plan to get a weapon I start a wrestler training so I can have someone with some discipline in case it's needed. A few migrant waves go by and I add a 2nd recruit to the military.
I breach the cavern and setup farms there. Some Trogdolytes come wandering by before the walls finish, but they're passive so it's all fine. Then somehow a fight breaks out. I check in and there are 2 Trogdolytes and 2 of my civilians. I station the military down there as well, as that's what they're for.
Very quickly the Trogdoyltes become very weakened with bruises and openings and all sorts of things of that nature. So they pass out. Except so do the pulverizing dwarves. I try to force my woodcutter (training axe, but it's something) and miners to get involved, but when I recruit the woodcutter he drops the axe and not wanting to do the same thing with the miner my attempts to get him involved don't go anywhere.
Eventually one trog dies, the other wakes up though and kills 2 unconcious dwarves before I finally bring him down. Of course he manages this while just about his whole body is broken and bruised. Anyways that was quite the ordeal.
I finish the wall, but due to some food issues I'm short on food and leave a door to continue some gathering operations. A troll decides he wants to stroll in. Except he's not hostile either. He wanders the fort a bit scaring himself when he encounters some of my dwarves and I just sort of leave him there since I can't kill him anyways.
Eventually my miner decided he was tired of the troll so as he walked by the troll he stuck his pickaxe in his head a few times, killing the troll without it getting a hit in, and then proceeded on his way.
So to recap... Bloody, beaten, bruised, nauseous, tired trogdolyte: 2 kills. Big bad fully healthy Troll: 0.
