I decided to go ahead and charge him with all my dwarves, so first I sent in my three dwarf and 8 war dog military in to soften him up, and give my civilians a chance to arm themselves. At first, the battle went well, as the war dogs and sworddwarves managed to keep him occupied. No damage was done, but the titan was becoming very tired, and my war dogs were no longer imitating birds.
Alas my marksdwarf ran out of bolts, and ran up to beat the titan with her iron crossbow. Surprisingly, this did more damage than my mighty sword draves and turned the titans right thumb gray. He then proceeded to kill all all of my of my dogs in a most spectacular fashion, as dogs where flying left and right one of which nearly smashed down the door to my fort traveling do doubt somewhere around half the speed of sound. Once the titan had killed the dogs and finished off my military, he stated to chase the puppies and massacred many of them, before chasing one off the southern end of the map and disappearing. Never shall the tail be forgotten of the brave puppy who sacrificed himself in an attempt to lead the horrible beast away into the great nether that lies beyond the borders of my CPU.
At least I'll have plenty of bone bolts to train up more marksdwarves.
