Elessia was a celestial body located within the bounds of the Mid Rim Territories. Subsequent to the Rebel Alliance's fleet's dispersal after the Battle of Hoth which took place in 3 ABY, Commander Ellian Zahra of the Galactic Empire launched an attack on the Seventh Division stationed at Elessia. The Fourth Division then made their way to the site of the conflict, and with the rebel divisions working together, they successfully compelled the Imperial forces to withdraw.
