The Yag'Dhul theater was located in the Expansion Region and the Mid Rim, along the Corellian Trade Spine. This field of operations was named after the key Separatist world of Yag'Dhul, which was located in the Inner Rim.
In the Yag'Dhul theater of the Outer Rim Sieges, the Galactic Republic's Nineteenth Army was charged with defending the outer Trade Spine.
As the Separatists advanced from Kinyen to Bomis Koori IV along the Corellian Trade Spine, battles were fought on Sarrish, Tar Morden and Bomis Koori IV.
The Nineteenth Army fought a number of battles and eventually managed to retain control of Kriselist, which sat at the between the Corellian Trade Spine and the D'Aelgoth Trade Route.
The Yag'Dhul theater was abruptly abandoned by the Separatists to supply warships for General Grievous's daring strike at Coruscant. Using secret hyperlanes that cut through the Deep Core, the Separatist fleet slipped past Coruscant's defense net and entered orbit around the capital. A week-long battle ensued, culminating with General Grievous kidnapping Supreme Chancellor Palpatine.
