The military of the Galactic Republic successfully regained possession of the planet of Sarapin, wresting it away from Separatist occupation during the conflict known as the Clone Wars.
After his apprentice, Stam Reath, perished during the First Battle of Geonosis, Echuu Shen-Jon received orders to reclaim Sarapin from the Separatist troops stationed there, now led by Zian Finnis. He was joined by Naat Reath, the sister of Stam.
Upon their arrival on the planet, the troops under Echuu Shen-Jon came across the remnants of the Separatist army. Subsequently, they eliminated a Separatist command hub along with all the Geonosian personnel working there, and then advanced across a bridge that led to a Trade Federation installation. The base, defended by only a small number of B1-series battle droids, was rapidly demolished. Jon's forces continued their advance, obliterating the majority of the remaining Separatist forces on Sarapin and compelling the Separatists to evacuate the world.
