From a community military fortress, a named dwarf by Snoopicus.
I knew he was a well trained wrestler, but he took out two goblin ambush squads, the second of which cut off his hand. A third popped up and he single handedly (haha) beat the crap out of them. He was making his way back to the fort to rest when a fourth goblin squad of crossbowgoblins popped up and pin-cushioned him four or five times. He finally gave in after that.
Secondarily, another dwarf whose name I forgot wandered around outside while the rest of the fortress tore itself apart from a tantrum spiral (its massively dangerous when every dwarf has high wrestling and weapon skills; and are fairly friendly). Another three goblin squads came out of ambush, this swordsdwarf killed the first two squads with what seemed like one slice each, sending entire halves of goblins every which way. The third squad ganged up on him, so he only managed to propel a couple away and cut one in half before they started fleeing. As he neared the edge of the map chasing them a siege dropped in, two squads on beak dogs lead by an elite crossbowgoblin. He proceeded to cut the crossbowgoblin's arm and leg off, that beak dog's tail and back legs off, and blendered the rest of the force without sustaining anything short of a light grey wound.
He then walked through the fortress, whose walls were splattered with blood and gore from the spiral, avoided any of the fighting, got a drink and went to bed.
