Pellaeon – Gavrisom Treaty The Pellaeon – Gavrisom Treaty , also known as the Bastion Accords , was the treaty of peace signed by the Imperial Remnant ' s Supreme Commander , Fleet Admiral Gilad Pellaeon , and the New Republic ' s Acting Chief of State , Ponc Gavrisom , in 19 ABY , marking the formal end of the Galactic Civil War . History . Early peace proposals . In the years following the Battle of Endor , Imperial and New Republic forces engaged in several temporary , localized alliances against mutual threats . 4 ABY saw the Bakura Truce against the Ssi - ruu k and the Battle of Saijo against the Tof s , and 7 ABY saw the Battle of Vahaba against the forces of Zsinj . The first tentative plan for comprehensive peace between the New Republic and Imperial Remnant was proposed by Imperial Admiral Betl Oxtroe to the New Republic Provisional Council in 7 ABY . Oxtroe ' s proposal would appoint Emperor Palpatine ' s 11 - year old grand - niece Ederlathh Pallopides as the titular Empress , with the former New Republic Councilors holding effective power . Although the New Republic was eager to negotiate , the secret talks soon ended when Oxtroe was assassinated , apparently by Noghri under the direction of Grand Admiral Thrawn . A truce between the Imperial Remnant and the New Republic was also proposed to Pellaeon in 13 ABY by Baron Ragez D ' Asta and his daughter , Feena D ' Asta , as the cost of their bringing the D ' Astan sector back into the Empire . Pellaeon dispatched Feena D ' Asta and Zam Basdor to negotiate with Mirith Sinn and Kir Kanos of the New Republic , but the meeting was disrupted by the Restored Empire faction who succeeded in killing D ' Asta . End of the war . In 17 ABY , after five relatively peaceful years , Imperial systems near the Hydian Way began to suggest the cessation of hostilities . The New Republic Senate was favorable and proposed Imperial officers to keep their offices in case of peace . Fearing an invasion , the Council of Moffs secretly contacted Admiral Natasi Daala , who had unified the replacement warlord s , and proposed a campaign against the New Republic . The campaign was disastrous for the Imperial Military and the Imperial Space was reduced to eight remote sectors in the Outer Rim . The final treaty was the brainchild of Pellaeon who , after acknowledging the impossibility of an honorable victory over the New Republic , proposed it to the Imperial Council of Moffs , select officers of the Imperial Starfleet , and other officials who , for the most part , grudgingly agreed . The Braxant sector ' s Moff , Vilim Disra , though openly siding with Pellaeon , chose to side with Imperial Guardsman Grodin Tierce and a con - artist named Flim to take advantage of the Caamas Document Crisis in order to nearly bring both the New Republic and the Imperial Remnant into separate internal civil wars . The plan , though , was foiled by agents on both sides . After Pellaeon and Leia Organa Solo engaged in preliminary talks aboard the " Millennium Falcon " in the Pesitiin system , the signing of the treaty was carried out by Pellaeon and Gavrisom at Bastion aboard the Star Destroyer " Chimaera " . Terms of the treaty . The treaty did not outline a surrender of any sort on the side of either the Imperial Remnant or the New Republic ; it instead put forth terms that would leave what remained of the Galactic Empire intact but with an end of hostilities between the two rival parties . It additionally opened the Imperial Remnant to trade and commerce with the New Republic , and put forth limitations on smuggling for both governments to enforce . In addition , systems in either government group would be allowed to choose their alignment , satisfying Imperial - loyal systems in New Republic space . The treaty also banned the use of cloaking devices .
