Space Battleship Yamato - Season 2 Episode 12

The Star Force spots a conspicuous-looking hollow asteroid, and decides that it would make for a natural repair dock in which they might repair the damage from the starflies. In reality, it is a Gamilon trap (of course), lined with electromagnetic force-fields. Upon entry, the Argo is stuck. Desslok's fleet moves in to destroy the Star Force with the Desslok Cannon. But Desslok's countdown is critically delayed by a phone call from Princess Invidia, and the Star Force manages to propel itself out of the force-field with the recoil force of the Wave Motion gun -- just in time. Invidia orders Desslok back before he can pursue the Argo. She waits to arrest him on false charges, fearing his designs on the Comet Empire throne. The Star Force arives at Telezart.
