The Battle of Ryloth, also known as the Ryloth campaign or the Liberation of Ryloth, was a major battle that broke out on the planet Ryloth during the Clone Wars. The battle pitted the Galactic Republic and its ally, the Twi’lek Resistance, against the Separatist Droid Army of the Confederacy of Independent Systems. The battle resulted in the liberation of Ryloth after the retaking of Lessu, in what became known as the Battle of Lessu. Years later, the recapturing of the capital would be named the Hammer of Ryloth in songs.
