Uncle Razhak has good explanation.
I, NORGGLE the STRONK, woke up and came in to hit Shoulder to turn the tide. I had to flee at crit and ran stedding. I checked my score. I had 1 HP LEFT !!! I saw LS guy run past me and didn't engage. 1 hit I was dead in ABS. But he fled. That would have turned the tide, because I, NORGGLE, was one of the KEY blockers that BLOCKED everyone south of the PITTRAP!
We killed 8 hoomans. The horde emerged on the hoomans and they lost.
