On world's militia force became in disarray, when their Legate was lost in the fight. Duke, along with his cousin Commander Erik Sandoval-Groell coordinate and led their troops to route Liao troops off planet.
It wasn't until late October when the last of Liao forces left on planet were hunted down. In notable fight, Commander Sandoval-Groell with Ghost Legion's BattleMech elements on planet went Mech hunting arctic reaches of the planet. With five BattleMechs, they were able overwhelm lone downgraded Clan Tundra Wolf that tried elude the into the ice region.
After securing planet, word of Faction leader was lost New Canton begun to circulate. However, it prove to be false. Bulk of the SwordSworn forces on New Aargon headed out to the next Incursion hot spot, Halloran V. Duke briefly meet up with his forces at SwordSworn fleet staging area in Pleione system. There he named Davion Guards' commander, Justin Sortek as Campaign Commander for next assault against the Liaos.

The base isolated in planet's arctic regions, kept his people from bulk of the enemy force. His Liao opponent landed in heart of planet's populated continent of Georama. Liao forces were quickly pushed the defending SwordSworn troops out of position and took the planetary capital of Jerome within days of fighting. This was due to Sortek reluctance to commit his forces fearing it was a trap. Isolated in Arctic region, Sortek's forces were low on fuel and ammunition. In bound on a dropship, Commander Sandoval-Groell attempted to advice Sortek in what he could do, but was limited on intelligence due to his distance from the world.
After landing on planet, the Commander was able organize better defense as Liao forces begun to marshal its forces on shores closest to the Ravensgale continent's heavily cliff laden shores.

Liao Aerospace forces, unwilling risk being shot down by the Fort's powerful array of aerospace defense towers, use their amphibious assault penetrate the base's defenses to knock out the towers. SwordSworn's coast defense batteries first fight waves of BattleMechs which emerge from sea, after being dropped off by special commercial ocean vessel. Following the 'Mechs on the shore being damaged by SwordSworn artillery and missile batteries, are combination of VTOL and hovercraft base vehicles help penetrate their coastal defenses. After overwhelming SwordSworn port defenses, the Liaos land heavy ground combat units via ferry try get through the one of the bases narrow vehicle tunnels.
Despite falling back, the SwordSworn give good show by mauling incoming Liao forces, however they manage penetrate the base interior perimeter. The defense towers fall one by one in onslaught of Liao ground forces. When all lost, the Dropships from orbit descend on the scene and hot drop their cargo of 'Mechs. However, SwordSworn are saved, as the Duke and his forces were able overwhelm the Liao's Dropships and slip in their place rescuing beleaguered forces on the ground.
After overwhelming the Liao invaders, Duke's additional forces drop off supplies. Liao forces at fort and in Georama retreat from the planet. Its learned Liao forces had stripped considerable amount of its defenses to amount invasion St. Andre.
