After the Xenos destroyed the Rio Grande, High Command moved the Harmony to defend California Minor.
Seeing the success of the Xenos, Liberty Rogues and Lane Hacker leadership form a joint-attack plan.
Gathering fighters, bombers, and gunships, the two groups launch an,attack. The Hackers exit Magellan and attack San Diego Border Station. Damaging the communications array, the station surrenders.
At this time, Rogue forces launched an attack at California Minor. But they did not know Harmony was there. Caught unaware, Harmony and her escorts slaughterd most of the Rogues.
Then the Hackers show up.
Launching an assault, Harmony and her escorts, at first, fair well. Then a Hacker bomber managed to get through the fire and launch a Nova Torpedo into Harmony's flank. Causing catastrophic damage, the Harmony unleashed a final salvo, catching a Rogue Gunboat. The Harmony's escorts startes to fall, until four fighters remained with the last gunboat, the Endurance. It seemed Minor would fall, had not a last-minute SOS had been sent by Harmony before she went down, prompting Battle Group North to arrive. Battle Group North comprised of three seige cruisers: The Thalia Grace, the Jason Grace, and the Annabeth Chase, along with two full fighter wings. The pirates turned to combat the reinforcements, but they,were battered already. Losing all thier gunships, and outnumbered, the pirates began to retreat from BGN. As they approached the Jump Gate to Magellan, the cruisers and thier escorts broke off. Jumping, thinking they were home free, the piratws froze when the Anti-fighter battlecruiser Omar Bradley and its escort met them. The Harmony, lost with all hands, was avenged.
At Los Angeles, the Yukon and her escorts pushed the Pirates back. But neither group was resdy for the Rogue assault on,Riverside. The station never stood a chance.
With the loss of Riverside and the Harmony, Navy forces were severly hampered, as the Omar Bradley was stationed at Willard. The Pirates of California managed to set up a new base in the second ice field. Navy and police forces drew away, only patrolling the two inhabited planets and Willard as pirate activity grew.
