Hmm.. I recall that the Galaxy Gun was poised to target several NR fleets hiding in deep space. Also, Pinnacle Base had a large defence fleet in orbit. You are probably right that the NR decided to play hide and seek, but from the way things were looking, the NR was running out of time. However, it seems from the EC that there was some fighting. Recall that Pellaeon abandoned the Chimera and it fell to NR hands.
