Amise Griff Admiral Amise Griff was a Human male officer of the Imperial Navy who commanded the Sector Group in the Bright Jewel Oversector and oversaw the development and construction of the " Executor " - class Star Dreadnought at Fondor . He later commanded the Blockade of Yavin . Biography . Griff was loyal to his Grand Moff , Governor - General Nox Vellam , but after the Battle of Yavin , he found himself reassigned to serve under Darth Vader ' s direct command . At first , he served as an agent provocateur on Fondor , a role in which he proved successful ; he infiltrated a cell of traitorous officers with part in the " Executor " construction , regularly reporting on them to Vader . The officers were not very sympathetically inclined towards the Rebels , but were growing jealous of Vader ' s unique position in the naval hierarchy and hoped to weaken him by selling the " Executor " schematics to them . By feigning sympathy for their cause and organizing their operations successfully , Griff eventually became their leader . Griff was ready to arrest them when Luke Skywalker , their Rebel contact , arrived , and Vader ordered his capture . Griff then befriended Skywalker and helped him in his mission , still posing as a Rebel sympathizer . After some time , he formed a new plan : to organize a meeting between Skywalker and the conspirators to incriminate them and set up a trap for the Rebel hero . However , Vader insisted on personally supervising the operation , and Skywalker felt his powerful dark presence through the Force . Although Griff ' s stormtroopers managed to arrest the traitors , the now - alerted young Jedi escaped , bringing the schematics with him . Later , Griff was placed in charge of the Blockade of Yavin . This long , drawn - out operation was marked by rivalry between Vader ' s supporters and Vellam ' s . Early in the operation , Griff warned that the blockade was ineffective and that the Rebels were steadily building up their fleet , advocating a decisive strike before the balance shifted to their favor . Vader , however , was too preoccupied with a scheme involving a fake Obi - Wan Kenobi to engage in such an operation at the time , and Griff , stretched thin , watched his numerical superiority dwindle . When the Rebels later mounted their final escape attempt , Vader once again pursued his own agenda , this time to leave a portion of the blockade deliberately weakened , allowing the Rebels to escape so that he could he lure them into a trap , again not bothering to inform Griff . Instead , the Admiral spotted the flaw by himself , sending three Star Destroyers to reinforce the breach and taking personal command of this force . The Rebels , led by Luke Skywalker , managed to defeat Griff ' s fighters and escaped past his positions at the climax of the siege . He then opted for a gamble and ordered an immediate hyperspace leap after the fleeing enemy . With all the required information , the plan may well have worked . As it were , however , he brought his fleet out of hyperspace too close to Vader ' s flagship , the " Executor " , which had secretly been waiting for the Rebels at this precise spot , and the ships collided . Griff was killed and the three Star Destroyers that collided with the " Executor " were destroyed by the impact ; the " Executor " lost its shields but suffered no major structural damage . It was , however , delayed long enough to allow the Rebels to escape . Personality and traits . Griff was an ambitious man with few moral scruples , always ready to take advantage of the mistakes of others . He was also more than a little vain , wearing an expensive fur - brimmed coat , in addition to his standard service uniform . However , he was a competent , albeit at times somewhat brash , naval commander , and an accomplished agent with a working knowledge of ground combat tactics , making up for some of his other character flaws . Behind the scenes . In the " Classic Star Wars " comics in which he appears , Griff wears a non - standard , all - red rank insignia , rather than a standard admiral ' s badge .
