Freja Covell Freja Covell was a male Human from Corulag who served as a general in the Imperial Army . One of Grand Admiral Thrawn ' s chief army commanders during his offensive against the New Republic , Covell led the takeover of the abandoned headquarters of Talon Karrde ' s organization on Myrkr . He was later killed by the insane clone Joruus C ' baoth not long before Thrawn himself died at the hands of the Noghri , Rukh . Biography . Covell had freshly graduated from the Academy when he was made a junior officer in an Army regiment commanded by Colonel Maximilian Veers . Under the colonel ' s tutelage , Covell learned to command ground forces and grew to love the AT - AT divisions as much as Veers did . They both understood the power of walkers and the fear they generated in the enemy . To sit in the cockpit of a walker satisfied Covell like nothing else could . Veers saw himself reflected in the younger officer , so that when Veers was promoted to general and given command of Darth Vader ' s ground forces in 3 ABY , he brought Covell with him , where Covell ' s excellent performance earned him the rank of colonel in charge of one of Veers ' battlegroups . Lieutenant Colonel Freja Covell managed to get the backing of the Assassin ' s Guild to fight three Rebel SpecForces units on Archais . The battle of Archais put both the Shroud and Eclipse Team s on the ropes . At that same moment , Rebel officer Mosara Thiirn deserted , surrendering her ship and herself to Covell , which led to an increasingly bad situation for the Rebel forces . Unfortunately for the Empire , Thiirn did not know any information they were unaware of . In the Battle of Hoth , in which Veers ' assault force routed the Rebel troops defending Echo Base , High Colonel Covell served as Veers ' " first officer , " and personally commanded one of the AT - ATs assigned to Blizzard Force . The Rebel tactics brought down his walker , wounding him in the process , but he made a good showing of himself and his command abilities . Despite his wounds , he got to safety and took charge of a stormtrooper group , which routed a larger number of Rebel troops before they could dig into defensive positions . Later , Captain Gilad Pellaeon promoted Covell to the rank of Major General and placed him in command of the ground forces aboard the " Chimaera " . Subsequently , Grand Admiral Thrawn advanced Covell , now a general to a position of senior leadership in the Army . During Thrawn ' s campaign , General Covell commanded numerous ground assaults — often leading from the front — and was finally assigned to the protection of Wayland . At Wayland , Joruus C ' baoth took control of his mind with the Force , and in fact replaced parts of Covell ' s mind with his own . However , a group of ysalamir i created interference with the Force that severed the connection . Covell ' s mind was compromised severely — while he lived for a short time inside the ysalamiri ' s bubble , long enough to relay some " special orders " given to him by C ' baoth , he was dead before the next morning . Personality and traits . Covell was a brilliant ground tactician . Like Veers , Covell mastered the commanding of the AT - AT and AT - ST units in battle during the post - Endor campaigns , ensuring that they would continued to be used by Imperial ground forces for years to come . Many of Covell ' s innovative ground battle tactics were adopted by later Imperial Army commanders . Covell disliked Imperial Navy officers , thinking them to be afraid to leave their ships and enter real combat .
