So, my Librarian was locked in combat versus Ymgarl Genestealers, when he periled his last wound in the movement phase. He was the last of his squad which meant that the ymgarls were suddenly not in combat anymore and... Do what?
I couldn't find anything about squads wiped out outside the assault phase, so we rolled for it and he stayed put.
Did we miss something? Consolidation doesn't seem unreasonable in the situation to me.
