A Peacekeeper armada under the command of Scorpius ambushed a convoy of Scarran dreadnoughts in orbit of a ringed gas giant. Using the planet's rings as cover, the fleet of command carriers was able to surprise the dreadnoughts, launching Prowlers and Vigilantes and destroying a dreadnought in the opening salvo as the Scarrans scrambled to defend themselves. Though the Scarrans were able to launch Strykers to meet the harassing Prowlers led by Captain Braca, the Peacekeeper forces were clearly closing on victory.
