In a recent Blue Dwarf storyline, a massive fleet lead by an evil-converted Jay Chrysler attacked Earth.
Moving on from it's string of victories against Space Corps fleets, The Hymenoptera attacked Earth head-on. Defended by a fleet of the Earth's last hope, transport ships, run-down cruisers and half-wrecked military vessels, Earth had no chance. The civilian fleet knew they were destined to death, with no chance of winning - their only victory would be to delay the Hymenoptera for a few minutes longer, allowing more time for people to be evacuated.
The Blue Dwarf uses its wormhole drive to enter into the fray, but still cannot prolongue the destruction of the Earth.
