Battle of Orion IV

"Freedom and liberty are truly gone from the galaxy."

- Mon Mothma, moments before her death

The Battle of Orion IV was the last engagement of the Continuation War in 6 ABY, which saw the death of Mon Mothma and the fragmentation of the Alliance Remnant. After a series of various victories against the Remnant, the Galactic Empire launched an assault on the Rebel capitol planet of Orion IV. After the base's defenses were bombarded from orbit, the Stormtrooper Corps and Imperial Army, under command of General Sakai, stormed the facility. Mon Mothma was executed inside by stormtroopers.

Aftermath
The Continuation War ended with the deaths of Mon Mothma, as well as General Crix Madine, at Orion IV. The Empire was unchallenged for several years, before the Yuuzhan Vong invasion.
