Invasion of Corellia

Pre-Invasion:
The Duros Genocide began shortly before the Invasion of Corellia, with half of the forces going to either system.

Invasion:
Throughout the invasion, the Sith engaged formidable opponents, the first time they had done so during the course of the war. One of them was the former leader of the Alliance himself, Nathanaeu Bastele, who had survived his brutal injuries during the fall of Coruscant and was now the leader of the Corellian resistance fighters. For years, the resistance engaged in guerilla warfare, choking off Sith supply lines, bombing Sith facilities, and creating just enough setbacks to keep the Sith from accomplishing their objectives. Both sides knew this could not last forever, and indeed it did not. By the campaign’s end, most of Corellia’s primary rebel holdouts were in shambles and the Sith had secured both the local governments and the major planetary resources. Though pockets of resistance would remain, the Sith flag flew over the skies of Corellia.

Post-Invasion:
The defeat of Corellia caused the cooperation of the Core worlds for the Sith.
