Imperial Skirmishes The Imperial Skirmishes was a campaign launched by the Imperial Remnant and the replacement warlord s in 17 ABY against the New Republic . The result was an Imperial defeat that would end the Galactic Civil War . Prelude . In 17 ABY , after four relatively peaceful years , Imperial systems near the Hydian Way began to suggest the cessation of hostilities . The New Republic lifted its ban on former Imperial officials holding elective office . The move was intended as a peace offering , but the Moffs saw it as the prelude to an invasion . Fearing invasion , the Council of Moffs secretly contacted Admiral Natasi Daala , who ' d returned to the Deep Core and unified the " replacement warlord s " , ambitious beings who had taken control of what little infrastructure remained after Pellaeon abandoned the Deep Core and replaced the officers Daala had killed at Tsoss Beacon . Daala was convinced to fight , and the Moffs ordered Pellaeon to begin another campaign against the New Republic . The New Republic was recovering from the Almanian Uprising and appeared divided . Furthermore , since the Orinda campaign the Imperial Remnant had received an injection of forces from the Black Fleet fleeing the Yevetha , among them the prototype Star Destroyer " EX - F " , renamed the " Rakehell " . Pellaeon - now a Fleet Admiral - thought the plan mad , but hoped to that he could win a few quick victories to satisfy the Moffs before offering peace terms to the New Republic . The campaign . What followed was an unmitigated disaster for the Imperial Remnant . Daala struck out of the Deep Core but her fleet was shattered by Garm Bel Iblis at the Battle of Columus . She was forced into a blind hyperspace jump and thought dead until she re - emerged in 40 ABY . Pellaeon ' s attack began well : he took Adumar and won surprise attacks on Taris and Battle of Champala on the Hydian Way , pushing all the way to the edge of the Core Worlds , but with Daala defeated , Ackbar and Bel Iblis were able to bring the full weight of the New Republic Defense Force to bear . The Second Battle of Champala was an Imperial rout . Pellaeon was chased back to Imperial Space , which was rapidly reduced after defeats at Ketaris and Tangrene . Hoping to salvage a victory , Pellaeon deployed his surviving dreadnoughts " Dominion " and " Megador " , as well as the " Rakehell " , at Anx Minor . The Battle of Anx Minor was a disaster , with the " Megador " and the " Dominion " suffering severe damage in the detonation of the " Rakehell ' s " antimatter reservoir . Pellaeon ordered an immediate retreat to Bastion . Aftermath . New Republic forces under Ackbar and Garm Bel Iblis reduced the Imperial Remnant ' s realm to a mere eight sectors , with Bastion , Yaga Minor and Muunilinst the only planets of note . This time the New Republic decided to not leave the initiative to the empire like the previous years . In 18 ABY , the New Republic fleet continued to keep the pressure on the Remnant , more particularly during the Corellian Crisis . The Remnant would remain bottled up in its eight sectors for another two years until its stunted economy and hopeless position forced Pellaeon to sue for peace . Despite the Caamas Document Crisis nearly ruining negotiations , this eventually resulted in the Pellaeon – Gavrisom Treaty in 19 ABY and the end of the Galactic Civil War .
