The full story is downright heroic. I had begun a transfer from temporary workshops down in the valley to a fortified structure being carved out of the mountain peak. Almost all of my dwarves were safely tucked away, save one marksdwarf who was off duty inside the old valley's mine, when a goblin ambush hit. I locked him in the mines and the civilians in the new fort and my marksdwarves shot up the invader enough they retreated. I then let everyone back out for some lovely goblinite recovery. My marksdwarf who was in the mine is then walking his way back to the fort when surprise! A second goblin ambush of swordsgoblins, lead by a hammergoblin, jumps the poor marksdwarf at point-blank. He was armed only with his shield and dagger, with an iron helm and a mail shirt. It wasn't looking good, but the civilians had a chance to flee, save one. My chief medical dwarfette, baby in tow, was off to get a bucket of water, spitting distance from the goblins. If she was spotted, it was over for her and the fortress firstborn! I quickly get her to stop hauling the bucket, then she panics and runs off into the hills. Knowing my lone marksdwarf is doomed without help, I send in the rest of the miltia. Captain Likotstettad runs down the hill at full speed, an armored boulder of axe-wielding fury, and proceeds to tear into five goblins at once, starting with a leg-severing sneak attack on the enemy leader. Under a hail of iron bolts he proceeds to hack the swordsgoblins to bits, who are busy trying to chop the iron-helmed head of my marksdwarf off, who by this point had lost his left leg and arm and was most reasonably just laying there being as unkillable as possible. Things still looked bad until the Captain pulled this horrifying display of utter contempt for goblin-kind, prompting a rout as the quailing fiends realized their doom was nigh. Riddled with bolts they retreated, most perishing as the Captain hounded them down.
"Lady's-Savior" Inaletur is now recovering in the hospital and should enjoy a long career of breaking in new recruits through verbal berating and wrestling, while I think "Eyebiter" Likotstettad is going on quite a few walls.
