We live on.
The total number of invaders was 1 marksman squad, 2 maceman squads and 1 troll squad. I probably overestimated their numbers a bit last report, but overall it was around 50 goblins.
I drafted one squad of marksdwarves right before the battle, but all in all we only had 19 soldiers. I hoped that the entrance flood chamber would kill most of the goblins. It worked perfectly.
The first phase of the goblins involved goblins standing right in front of a massive gush of water out of the side of a wall. They tumbled down the hill, accumulating a couple minor injuries. The major hurt came when they fell down the side of the canyon, and drowned in part of the river-diverting apparatus.
Unfortunately, some goblins landed in the dry part of the canyon, and the dwarves were forced to fight. This fight was mostly uneventful, with major victories had on our side. But one recruit did die:Aban Matuldakost. It is probably worth mentioning that some trader died too near the beginning of the siege. He was loitering around the edge of the map. I don't remember his name.
The canyon was clear of enemies, but their were still some trolls and macemen alive, safe from the water-slide. So I closed off the floodgates, and sent the military out to kill them. This went well, until one of the trolls destroyed one of the floodgates. This sent him, Shem Oddomarek OmerKebul Morul and Kol Tanber Onolsresh Betan tumbling down the hill. Kol died of a fur robe to the brain, and Shem fell down into the canyon and died in mortal combat with a goblin. I picture that fight happening like gandalf and the balrog on a smaller scale.
So overall, it was a successful battle. 4 deaths, and a broken floodgate. Too bad two of the three surnamed dwarves in the fort died. Right now, it's hematite 8, and I'm scrambling to get that floodgate fixed. I don't think there is any backup floodgate is there? I think I'll use the pump method and see how it goes.
Sorry for no pictures, I can get them up later, but I'm not sure how to do it on here.
