Battle of Anx Minor The Battle of Anx Minor was one of the last major battles of the Galactic Civil War between the Imperial Remnant and the New Republic , occurring during the Empire ' s final campaign in 17 ABY . After a series of engagements , an armada of Imperial Star Destroyers under the command of Remnant Admiral Gilad Pellaeon engaged the New Republic Third and Fifth Fleets above the Outer Rim world of Anx Minor , located deep within Imperial territory . Commanding from the New Republic Star Dreadnought " Guardian " , the Mon Calamari Admiral Gial Ackbar inflicted heavy damage upon Pellaeon ' s ships , forcing the Imperials to retreat . The defeat prompted Pellaeon and the Remnant to sue for peace two years later , an initiative that brought about an official end to the war . Prelude . In 17 ABY , during the final stages of the Galactic Civil War , the Imperial Remnant under Admiral Gilad Pellaeon launched a series of offensives against the New Republic , fearing that the Republic was preparing to invade Imperial Space . Although initial skirmishes at Adumar , Taris , and Champala proved successful for the Remnant , the New Republic military quickly responded to the threat that Pellaeon ' s forces posed . The Mon Calamari Admiral Gial Ackbar , commanding from the " Executor " - class Star Dreadnought " Guardian " , led the Third and Fifth Fleets of the New Republic Navy into battle against the Imperial forces , routing them at Champala , Ketaris , and Tangrene . With Pellaeon pushed back into the heart of Imperial territory as a result of these defeats , the stage was set for a final encounter between the opposing commanders . The battle . The armadas faced off in battle above Anx Minor , an Outer Rim planet located near the core of Imperial territory . Ackbar , commanding from the Super Star Destroyer " Guardian " , led the New Republic Third and Fifth Fleets into combat against Pellaeon ' s force of Star Destroyers , which included two Star Dreadnoughts — the " Dominion " and the " Megador " — and the " Sorannan " - class Star Destroyer " Rakehell " , a weapons testbed . The resulting engagement between the two fleets proved to be the decisive end of the Empire ' s campaign . Near the conclusion of the battle , Ackbar ordered his forces to concentrate their fire on the " Rakehell " . New Republic Intelligence had determined a way to take out the vessel — there was a weak spot near its antimatter reservoir . Ackbar ordered his forces to target the armor surrounding the reservoir ; this barrage , coupled with attacks on the ship ' s engines , destroyed the weapons testbed and ignited its antimatter reservoir . The resulting explosion was powerful enough to obliterate six Star Destroyers in the vicinity and damage the " Megador " . Defeated , Pellaeon and the remaining Imperial ships fled the battle , retreating to the planet Bastion . Aftermath . In the end , Pellaeon ' s gamble on a final , successful campaign against the New Republic failed , the combined forces of the New Republic Third and Fifth Fleet having destroyed a significant portion of the Imperial Navy . The Empire ' s territory was reduced to eight Outer Rim sectors , and the Raioballo sector , where Anx Minor was located , was not one of them . This defeat , coupled with the Republic ' s close watch over the Imperial Remnant in subsequent years , prompted Pellaeon to assume direct command of the Remnant . In 19 ABY , two years after the defeat at Anx Minor , Pellaeon and the Council of Moffs sued for peace ; the Galactic Civil War was formally ended that year with the signing of the Pellaeon – Gavrisom Treaty . Behind the scenes . The Battle of Anx Minor was first mentioned in " The New Essential Guide to Characters " , written by Daniel Wallace and published in 2002 . In the book , the battle is described as having occurred after the Corellian Insurrection , while later sources place the battle as happening before . The Battle of Anx Minor was later mentioned in " The New Essential Chronology " , " The Complete Star Wars Encyclopedia " , and " The Essential Atlas " , none of which expanded upon the details of the conflict . " The Essential Guide to Warfare " , released in 2012 , provided some new details on the battle . Some confusion regarding the dating of the battle has existed : While " The New Essential Guide to Characters " originally supplied a date of 17 ABY ( " [ t ] hirteen years after Endor " ) , " The New Essential Chronology " proposed a generalization of 17 – 18 ABY for the Empire ' s final campaign ( of which the Battle of Anx Minor was the final engagement ) , and " The Complete Star Wars Encyclopedia " simply used 18 ABY for the date of the battle . " The Essential Atlas " and " The Essential Guide to Warfare " , the most recent sources to mention the engagement , both went with the original 17 ABY dating .
