Alliance High Command / Legends The Alliance High Command , also known as Alliance Command , was the military nerve center of the Rebel Alliance and Alliance of Free Planets , consisting of Mon Mothma , the Alliance Minister of War , the Chief of Staff ( CoS ) and her closest military advisors , including Bail Organa , Leia Organa and Jan Dodonna . Beneath Mothma , the Minister of War , and the CoS were the Alliance Supreme Allied Commanders , such as Admiral Gial Ackbar ( in charge of the Alliance Fleet ) , and Crix Madine ( in charge of the Alliance Special Forces ) . The High Command was responsible for setting over - all strategy for the Alliance , direction operations of the Alliance Fleet and Alliance Forces , command of all Alliance ground forces , and coordinating the Alliance Sector Commands . Structure . In large part , the brainchild of Bail Organa and his considerable knowledge of military matters from serving on the Galactic Republic Senate Military Oversight Committee , the Alliance High Command was flexible enough to wage coordinated insurgent warfare on a galactic scale , while still remaining under civilian control . At the top of the High Command was the Commander - in - Chief Mon Mothma . Directly below her in the chain of command was the Alliance Minister of War , the duties of whom were to keep the Commander - in - Chief ( CinC ) informed of military matters on a day - to - day basis . In the event the CinC became incapable of fulfilling her duties , the Minister of War would assume command of the war effort , until the CinC could return to her duties or the Alliance Civil Government could name a successor . Below the Alliance Minister of War in the chain of command was the Alliance Chief of Staff ( CoS ) , whose main duty was to act as a buffer between the CinC and lower echelons , deciding which problems required her attention , and which could be handled at lower levels . In the event either the CinC or Minister of War were indisposed , the CoS was authorized to act in their names . Below the Chief of Staff were Supreme Allied Commanders , who were each responsible for an individual command , such as Ordnance and Supply , and SpecForces Command . High Command was advised by an Advisory Council . High Command headquarters . The infrastructure of High Command typically operated from a planetary base , from where the majority of the Alliance operations throughout the galaxy were overseen . One of the first locations High Command used as their headquarters was a prefabricated base established in the ruins of the Jedi Enclave on the planet Dantooine . It was from the Dantooine base that the Alliance launched the starfighter strike that saw the acquisition of the technical data to the first Death Star . From Dantooine , High Command relocated to the newly built Massassi Station inside the ruins of the Great Temple on Yavin 4 . Much of the Alliance ' s activities during this time were under the direction of General Jan Dodonna , operating from Yavin Base . After rescuing Princess Leia Organa from the first Death Star , Luke Skywalker and Han Solo delivered her and the Death Star plans to the base . It was there that the battlestation data was analyzed , and from where the assault on the Death Star was launched . The Empire soon responded with a blockade of the Yavin system , and within six months of the Death Star ' s destruction , High Command was forced to evacuate the moon and relocate elsewhere . Following the evacuation from Yavin , High Command was forced to become increasingly mobile as the Empire intensified its efforts to destroy them . To greater protect them , the newly formed starfighter squadron Rogue Group was permantly assigned to the roving High Command group . In accordance with policy established by Mon Mothma , the bulk of the Alliance Fleet was to operate separately from High Command in order to avoid a catastrophe that would potentially destroy both . It was decided the Alliance could survive the loss of either its fleet or High Command , but not both . While reconnaissance teams were dispatched in an effort to locate a suitable site for High Command to permanently relocate to , they temporarily settled on the planet Thila in the Outer Rim Territories . The Thila base was only used for a period of a few months before it too was evacuated in the face of the threat of its location having been compromised . Rogue Group performed admirably during several skirmishes in the Thila campaign , helping High Command to evacuate . Fortunately , High Command had already decided on relocating more permanently to the ice planet Hoth . When construction on the new Echo Base was completed in 2 ABY , they moved their operations there under the command of General Carlist Rieekan . It was a mark of their true desperation that they were forced to hide themselves within the ice caverns of the remote and desolate Hoth . High Command operated out of Echo Base for about one year before it was discovered in 3 ABY by Darth Vader ' s Death Squadron , his personal armada of Star Destroyers . Vader launched a crushing ground assault that severely crippled the Alliance ' s war efforts . Only with another heroic effort by Rogue Group was much of High Command able to narrowly avoid destruction at the hands of the Empire and evacuate the ice planet . The surviving members of High Command , now without a planetary base , relocated to the predetermined rendezvous point with the Alliance Fleet beyond the galactic rim . With the Alliance facing a situation more desperate than ever before , High Command transferred their operations to the Alliance Fleet , using Admiral Ackbar ' s Mon Calamari Star Cruiser " Home One " as their mobile base of operations for the following year . When High Command discerned the location and details of the second Death Star , still under construction above the forest moon of Endor , they ordered the majority of the Alliance Fleet to convene above the planet Sullust , where they planned the assault on the battlestation .
