Aftermath of Hoth The Aftermath of Hoth , sometimes referred to as the " Mugaari Campaign " , was a series of Imperial actions in the sectors surrounding the Hoth system , immediately following the destruction of the hidden Rebel base . Having been defeated , Rebel Alliance forces fled their secret base in all directions , assisted by the supposedly neutral Mugaari . During this campaign , Imperial forces searched nearby sectors for fleeing Rebels , encountered various retaliatory strikes , secured their space installation , and staged a counterattack against a local Rebel task force . The Campaign . Patrolling jump point D - 34 . The first phase of the campaign entailed static searches of various vessels traveling through the sector around XQ1 Platform " Outpost D - 34 " . Various freight and trade craft moved through the system , permitting the Mugaari opportunities to smuggle fleeing Rebels . Imperial pilot s discovered Rebel stowaways aboard Bulk Freighter " Onece 3 " and Transport " Glich " as they attempted to pass through Imperially controlled space . Imperial Stormtrooper Transports began a capture operation just as Rebel shuttles arrived to rescue their discovered comrades . In the end , Imperial forces killed or captured all of the Rebels in their attempt to flee . Red Alert . Following the initial discovery of Rebel stowaways , intelligence gathered from the prisoners revealed Rebel intentions to mount an assault on Outpost D - 34 . In addition to information extracted from Rebel prisoners , members of the Secret Order of the Empire revealed that the Rebels had stolen a " Lambda " - class shuttle , and the Order expressed their intent to capture any Rebel leadership that may be present aboard this shuttle , should it arrive in the system . As expected , an enemy attack force consisting of X - wings , Y - wings , and Z - 95 Headhunters arrived to lay siege to the outpost . Imperial pilots stood by with Assault Gunboats and TIE Fighters to fend off the assault until the arrival of Admiral Flanken aboard the " Imperial " - class Star Destroyer " Hammer " . During the fighting , the shuttle " Scutz " arrived just as expected ; Imperial Gunboats quickly intervened , disabling it for capture . To the Empire ' s surprise , three CR90 corvettes arrived to join the battle just as capture operations of " Scutz " began . Despite the efforts of the combined Rebel and Mugaari attack , Imperial forces held Outpost D - 34 with the assistance of the Imperial Star Destroyer " Hammer " . Counter attack . After fending off the impending attack on D - 34 , Admiral Flanken ordered a counterattack on a Rebel and Mugaari cargo loading depot in the Tungra sector . Colonel Vistore , aboard the Nebulon - B Frigate " Fogger " , oversaw the task of destroying the depot . The " Fogger " began the assault on the enemy base by launching four flight groups of TIE bombers , covered by one flight group of TIE interceptors . The enemy depot consisted of cargo containers , cargo ferries , transports , shuttles , and Y - wing fighters , and was easily destroyed by proton torpedoes fired from Imperial TIE Bombers . The Imperial surprise attack resulted in the successful destruction of the enemy depot , encountering little resistance from the aging fighters and shuttles . Outpost D - 34 falls . While Imperial forces attacked the supply depot , Rebel forces succeeded in capturing Outpost D - 34 , forcing Imperial pilots into yet another sortie . Before the battle , agents of the Secret Order advised that spies may be among loyal Imperial forces , and expressed the need to capture additional Rebel prisoners . The frigate " Fogger " yet again led an assault against the Alliance force , consisting of transports , TIE Bombers , and TIE Interceptors . The Rebels attempted to counter the Imperial onslaught with X - wings , A - wings , Y - wings , the new Escort Shuttle , and transports of their own . Imperial forces again succeeded in repelling the enemy starships , and recaptured their station ; moreover , the Secret Order gained additional prisoners from the capture of the Container Transport " Gopher " . Attacking a Rebel light cruiser . After regaining control of Outpost D - 34 , Admiral Flanken traced the trail of the attacking Rebel forces back to the Bruanii sector . Flanken ordered Colonel Vistore to send his Assault Gunboats to rally with his own and assault the Rebel stronghold in a two - phase attack . Before the assault on the Rebel forces , Secret Order agents became curious about the source of all the Imperial equipment that was emerging from Rebel hands , and tasked the Imperial pilots to be on the lookout for additional stolen arms . Five flight groups of Imperial Gunboats emerged from hyperspace to find the Calamari Cruiser " Lulsla " , her compliment of fighters , and Rebel transports laying a minefield . The Assault Gunboats began the initial task of softening up the cruiser ' s complement of starfighters , prior to additional forces arriving to destroy the cruiser itself . During the engagement , Imperial pilots did discover Imperial weapons located in one of the cargo containers near the " Lulsla " . As Gunboats from groups Tau , Rho , Pi , Nu , and Mu succeeded in clearing out enemy fighters , they escaped into hyperspace just as transports and additional Gunboats arrived for the second wave against the Cruiser . Destroy the " Lulsla " . The transports Sigma and Omega began their attack on the cruiser , flanked by three groups of Assault Gunboats . The Gunboats swiftly moved to destroy incoming enemy fighters and the newly - laid Type B and C minefield . However , the " Lulsla " still held a respectable resistance with its remaining X - wing , Y - wing , and A - wing fighters . Secret Order agents had forecast the inevitable doom of the cruiser , warning that its officers and crew would flee the crippled vessel before its ultimate destruction . Just as expected , starship groups " Starway " , " Gargon " , and " Derris " emerged from the Lulsla ' s hangar right before it exploded under fire from Imperial transports and their proton rockets . Imperial Gunboats diverted from the fighting to eliminate the fleeing Rebels , sparing only their commander aboard the shuttle " Derris " , which was later captured by Transport " Zack 1 " . The aftermath . The Empire finally succeeded in pacifying the local sectors surrounding the Hoth system following the invasion . Imperial pilots played a key role in its success , appropriating valuable intelligence and capturing Rebel forces , speeding the accomplishment of the campaign . As impressive as this accomplishment was , it was also the beginning of Admiral Harkov ' s defection to the Alliance .
