Ingishnosig was a fine fort. It was most known for it's large war dog squad, which had over forty dogs in it. One day, Momuz Rigothsastres, commander of the military forces guarding the entrance, sighted a disturbance. Coming over the ridge, wearing steel plate armor and using crucible steel weapons, was a horde of orcs. "Man the defenses!" he yelled, as his single squad of champions and dogs began to fight back. Fortunately, someone pulled the lever, which sealed off the fort from the outside world. The battle raged on, and the orcs were outnumbered two to one by the dogs. However, nobody besides Momuz had armor, and it was bone armor at that. The first casualties were the extremely loyal and powerful war dogs.Then, the extremely powerful hammer lord known only as Uzbanik, appeared. He strode up to Momuz and bashed his head in with his steel hammer.

The remaining military dwarves were slaughtered by the horde.
Casualties:
Orcs: 3-4 Dwarves:8 champions, 40 war dogs.
