A week after the encounter, the Earth Federation sends the Tenth Divisional Fleet to reinforce TF Alpha. However, fleet commander Brian Aeno - who was approached by a New Desides representative days before - announces that his force will side with the rebels. Task Force Alpha and a Federation fleet from the Moon attacks the asteroid, forcing most of the rebels to pull out and head for the city, with a small contingent on Pezun providing cover fire and wiring the base to self-destruct with a nuclear weapon. Task Force Alpha realizes the deception and escape just before the asteroid explodes.
