Destruction of the Glory The Destruction of the " Glory " was the final battle fought during the Zaarin insurrection in the Unknown Regions . Background . Following the theft of the CR90 corvette " Vorknkx " , Grand Admiral Zaarin retreated into the Unknown Regions with an operational cloaking device . Grand Admiral Thrawn had a homing beacon hidden in the corvette and immediately followed Zaarin with his fleet consisting of the " Imperial I " - class Star Destroyer " Grey Wolf " , the Interdictor cruiser " Corvus " and the " Strike " cruisers " Ebolo " and " Daring " . With the Interdictor able to keep Zaarin in one place , Thrawn intended the complete destruction of his enemy and the end of the Zaarin Insurrection . The battle . Thrawn brought his forces out of hyperspace with the " Grey Wolf " and " Corvus " just close enough to trap the " Glory " , but far enough away to be safe from Zaarin ' s numerous TIE Defenders . Thrawn ' s two " Strike " cruisers came out of hyperspace right on top of the " Glory " and launched their squadrons of TIE Avengers led by Maarek Stele . The " Grey Wolf " also launched fighters and bombers to attack the " Glory " and other capital ships under Zaarin ' s command . While the two " Strike " cruisers attacked the " Glory " , the " Grey Wolf " lagged behind to protect the " Corvus " . Zaarin , attempting to escape , split his TIE Defenders into several groups , one to eliminate the TIE Avengers , another to destroy the strike cruisers , and one to destroy the Interdictor and possibly the " Grey Wolf " . As the two strike cruisers were so close to the " Glory " , they quickly succumbed to a concentrated proton rocket attack by the Defenders . The fighters also managed to kill off a few Avengers , but the superior skill of Maarek Stele destroyed them . The TIE Defenders heading for the " Corvus " were also intercepted and destroyed , although they did manage to do some damage . Without his superior fighter cover , the " Glory " quickly took a number of rocket and torpedo hits from the TIE bombers , causing Zaarin to evacuate the vessel in a number of transports , shuttles , and the " Vorknkx " . The shuttles and transports were all destroyed , but the " Vorknkx " engaged the cloaking device , evaded the fighters , and fled into hyperspace . The death of Zaarin . What Zaarin did not know was that Thrawn had altered the reports of the cloaking device , eliminating the portions that showed that the cloaking device was unstable in hyperspace . As the corvette leapt into hyperspace , it exploded , resulting in the first death of an Imperial Grand Admiral . Aftermath . Thrawn had defeated Zaarin , but this might have had some unforeseen consequences . Zaarin ' s use of advanced starfighters meant that the Empire would use less of them , resulting in Rebel fighter superiority , a crucial advantage in many battles . Moreover , Thrawn ' s presence in the Unknown Regions meant that he was not able to be present at the Battle of Endor , and prevent the death of the Emperor . Years later , Gilad Pellaeon would hypothesize what would have happened if Thrawn had been at Endor . Thrawn would remain in the Unknown Regions , continuing to strengthen the Imperial presence , until returning in 8 ABY . Both " Grey Wolf " and " Corvus " would not be seen again , presumably joining the forces under the Empire of the Hand .
