Estafor was a forested planet located in the Kanz sector of the galaxy's Outer Rim Territories. Estafor was located within Separatist space during the Clone Wars and was later aligned with the Alliance to Restore the Republic. During the Galactic Civil War and shortly after the Mid Rim Retreat, several Rebel ships regrouped over Estafor but were attacked by the Imperial II-class Star Destroyer Suppressor. The 43rd Infantry survived the attack and made it to the surface of Estafor, so Imperial forces set up a prefabricated ground base to hunt down the 43rd. The Battle of Estafor lasted for nearly a month until the Rebels successfully contacted reinforcements to save them and the Imperial forces were defeated, ending the battle.
