Cleansing of Coruscant

The Cleansing of Coruscant was a major battle that took place during the Charon War that killed 32% of Coruscants One Trillion inhabitants.

Prelude
Prior to the Battle's beginning, the Charon had won a devastation victory at the Battle of the Core, in where they were able to deliver a devastating blow to the UGF. Following the victory, withdrawing UGF forces attempted to lead them away from Coruscant, however, the Charon already knew of its importance, and would arrive at the planet mere hours after the victory.

The Battle
As the battle begun, the UGF warfleet, though more numerous, was forced on the defensive by the Charon warfleet. It took only an hour for Charon forces to pierce Coruscant's defenses and make it to the ground, where intense ground combat began, and many civillian lives were lost in the process. After three hours, the Charon Warfleet was able to enter atmosphere and begin bombarding the planet as the UGF tried to regroup their fleet. The Charon, in the UGF's absence, was able to topple multiple skyscrapers, killing millions, and the impacts killing millions more. After four hours, the UGF launched a desperate assault to take out the Charon warfleet, and were repelled almost instantly. They were forced to retreat into the lower levels of Coruscant, where the Charon refused to follow due to the size of their Warships. After the retreat of the UGF, the planet would be ravaged by weeks of constant bombrdment, ending in the loss of Billions of lives.

Aftermath
After the battle, Coruscant did not recover from the devastation for almost 70 years, and the Charon held onto Coruscant for 11 Months. In the Undeworld, UGF forces and many partisans, including the Underworld Police, continued to fight until occupation ended.
