"Now that the war is winding down—"
"Winding down. It's not over?"
"Pockets of resistance remain, especially on Umbara. Our forces are engaging in several, shall we say, pacification exercises to bring about a lasting peace."
―Lieutenant Commander Orson Callan Krennic and Lyra Erso[src]

At some point between 19 BBY and 18 BBY, a rebellion against the Galactic Empire occurred on the Expansion Region planet Umbara during the early months of the Imperial Era. The Imperial Military was deployed to put down the resistance as part of a wider anti-insurgent campaign, with Lieutenant Commander Orson Callan Krennic framing it as a pacification operation.

Prelude[edit | edit source]

During the Clone Wars, a galactic conflict fought between the Confederacy of Independent Systems and the Galactic Republic, the Expansion Region planet of Umbara remained a member of the Republic until the assassination of Senator Mee Deechi, which made the world join the Confederacy.[3] Thus, the 501st Legion and 7th Sky Corps of the Grand Army of the Republic were deployed to invade and take back Umbara[4] in 20 BBY.[5] In spite of the betrayal of Jedi General Pong Krell,[6] the Republic overwhelmed the Umbaran Militia's impressive defense. The battle was a devastating defeat for the Umbaran government,[7] with even their capital falling to the Republic Army.[6]

The rebellion[edit | edit source]

Previously the site of a battle during the Clone Wars, Umbara was again home to fighting during the early Imperial Era.

In 19 BBY,[2] concurrent to the end of the Clone Wars, the Republic was transitioned into the Galactic Empire by Supreme Chancellor Sheev Palpatine.[8] At some point between 19 BBY and 18 BBY,[2] during the months following the proclamation of Empire, the newly-formed Imperial Military was deployed to combat various pockets of resistance leftover from the Clone Wars. One of these rebellions against the Empire occurred on Umbara, with the battle there being notable among the Imperial counterattacks. When speaking to researchers Lyra Erso and Galen Walton Erso, Lieutenant Commander Orson Callan Krennic claimed the Empire's response to the rebellion at Umbara and other locations was a series of pacification exercises that would bring about peace.[1]

Aftermath[edit | edit source]

Eventually, Umbara became part of the Empire,[9] with Ensign Eli N. Vanto believing it would be unlikely for the Umbarans to risk another devastating defeat, as had occurred during the Clone Wars, by resisting. Nevertheless, the Umbara system would again be the sight of fighting when the insurgent leader Nevil Cygni deployed a force of vulture droids against an Imperial taskforce. While the battle was technically an Imperial victory, Cygni had actually engineered the skirmish to ensure the Empire would take over Umbara's mining industry, knowing it would be easier to bribe Imperial inspectors than Umbaran ones.[7]

Behind the scenes[edit | edit source]

The rebellion on Umbara was first mentioned in the 2016 novel Catalyst: A Rogue One Novel by James Luceno.[1]
