Siege of Inyusu Tor

"Give me a break. I know my way around Sullust. After all, I did help liberate the place."

- Shriv Suurgav mentioning the battle to Lando Calrissian

The Siege of Inyusu Tor, also known as the Liberation of Sullust, was a battle that occurred during the Galactic Civil War between the Alliance to Restore the Republic's Sixty-First Mobile Infantry and the Galactic Empire on the volcanic planet Sullust.

The initial siege
Shortly following the Battle of Hoth, the Sixty-First Mobile Infantry initiated Operation Ringbreaker. Devised by the former Governor Everi Chalis it sought to force Imperial redeployments from the shipbuilding world of Kuat by assaulting worlds such as Obumubo, Naator, Xagobah and the asteroid mines of the Kuliquo belt, thus allowing for the them to assault Kuat Drive Yards. When the Sixty-First jumped out of hyperspace a mere half million kilometers from the planet in an effort to rapidly deploy drop ships to assault the Inyusu Tor mineral processing facility, the attack ultimately went awry the following day when the Imperial Vixus Squadron ambushed their troop transports and shot down their CR90 corvette the Thunderstrike, stranding the company on the planet.

Preparing for the assault
Their Captain Hazram Namir decided to reach out to the Sullustan resistance for help but he and his men were attacked when searching in Sullusts capital Pinyumb. The Sullustan resistance leader Nien Nunb rescued Namir and took him back to the other resistance members. Namir realised that the group of four freedom fighters would be of no help but devised a plan that would have the Sixty-First face the coming imperial forces and the Sullustan resistance and willing members of the Cobalt Laborers' Reformation Front take Pinyumb. Namir went back to Inyusu Tor and faced Chalis who wanted to have the Sixty-First evacuate and continue Operation Ringbreaker. He thwarted her plan and prepared the Sixty-First for the coming attack.

Defending the facility
The next three days would result in the bloody siege of Inyusu Tor, initially being in the Empire's favour as the Imperial-class Star Destroyer Herald arrived in the system and the Imperial Army utilized overwhelming force to surround the rebels on the mountainside facility. The Sixty-First had formed three defensive lines with the outer housing various squads hiding behind boulders and slopes, the middle housing a more organised groups of firing squads and the inner housing soldiers and artillery for the All Terrain Scout Transports the enemy had. The Sullustan resistance finally convinced the Cobalt Laborers' Reformation Front to rise up in Pinyumb, they were able to mount a fierce resistance. The Herald had to face the Thunderstrike's escort the Braha'tok-class gunship Apailana's Promise which had formerly retreated when the Corvette was shot down and come back to help.

During the battle, Chalis fled to the nearby city of Pinyumb, killed an Imperial officer, and attempted to escape the planet in a shuttle. Before she was able to leave the atmosphere, the Herald locked onto the shuttle with its tractor beam. After being taken prisoner, Chalis revealed the shuttle had been rigged with ion charges and actives them, dealing major power loss to the Star Destroyer. Unable to power its weapons and maintain altitude, the ship began to drop towards the surface and was forced to leave the system. Without the Star Destroyer's help, the Imperials significantly weaker and the Sixty-First's lead engineer Vifra and her team used machines donated by the Sullustan resistance to excavate ports for lava to flow towards the ground forces. Being overwhelmed, the Imperial forces were defeated.

Aftermath
In the following days more uprisings broke out all over Sullust taking it for the Sixty-First. An interim government would be installed in Pinyumb and heavy losses sustained by the Sixty-First would ultimately cancel Operation Ringbreaker, allowing the company to act as a temporary police force for the Sullustan people. Subsequent pirate broadcasts and intercepted Imperial signals indicated further insurrections across the planet, delaying the inevitable Imperial counterattack.

The victory on Sullust ultimately played a key role in the outcome of the Galactic Civil War, as the planet was eventually used as the staging ground for the Alliance Fleet before the Battle of Endor.

Some time after the battle, the Empire returned to the planet and reactivated an abandoned weapons factory, in an effort to covertly resupply their dwindling forces. The installation was destroyed by Lando Calrissian and Shriv Suurgav, a veteren of the siege of Inyusu Tor, shortly before the Battle of Jakku.
