Levels were dinged and those that received them were called to
buy power leveling. DuGalle is a staunch believer to buy power leveling mission and carries out his orders with precision.
Despite a twelve-year age gap, he is also a childhood friend of his vice-admiral, Alexei Stukov. Despite his experience, DuGalle is prone to believe faulty intelligence from Samir Duran throughout Episode to
buy power leveling and thus causes Stukov to abandon the fleet. DuGalle accepts Duran's theory that Stukov is a traitor and allows Duran to kill his friend, only realizing his horrible mistake too late. The true traitor Duran vanishes after Stukov's death, but DuGalle is still successful in foiling Duran's plans for sabotage. He goes on to capture the Overmind and occupy the majority of the sector by the end of Episode to buy power leveling.
However, as a result of demoralization, limited manpower, and an alliance of enemies led by Kerrigan, the fleet is slowly but surely pushed back throughout Episode to
buy power leveling, and when a last-ditch attempt to recapture Char fails, DuGalle and the fleet attempt to retreat. In Brood War's final cinematic, DuGalle composes a letter to his wife, informing her of the fleet's failure and taking full responsibility for Stukov's death to buy power leveling.
