Invasion of Coruscant (Line of False Time)

Prelude of invasion
After pyrrhic Sith victory during invasion of Inner Rim, when Sith Imperial Army lost large number of invasion forces, Imperial Army Command decided to start difficult and hazardous step. Sith Imperial Army called reserves to tie numerious Republic Army reserves remaining in Core Worlds and Inner Rim, while Imperial Army formed "Sith Invasion Group" as massive military units composed of war-experienced, best equiped and best armed forces to move on Coruscant, while remaining Sith Army will struggle with Republic reserve forces.

Feint attack by Sith Imperial Army reserves was successful, when Republic Army reserves assaulted Sith Imperial Army near Tython in bloody skirmish. In same time, Sith Invasion Group attacked Coruscant, with support from Zakuul expeditionary corps and different allies.
