The battle of Batonn was waged by the Galactic Empire against insurgents who operated within that sector. Admiral Thrawn commanded the Imperial forces and emerged victorious against the rebels. During the battle, civilian casualties far exceeded those of the rebels, and while this did not sit well with some officials like Agent Kallus of the Imperial Security Bureau, the Empire considered these margins acceptable as it eliminated the rebel threat in the sector.

In recognition of his victory at Batonn, Thrawn was promoted to Grand Admiral by the Emperor, Darth Sidious. Soon thereafter, he and the Seventh Fleet that he commanded were tasked with eliminating the rebel threat in the Lothal sector.
