Garret served as a general within the New Republic Defense Force during the years that came after the Battle of Endor. He oversaw a siege on the planet named Basilisk, which the Imperial forces had dominion over. Following the Katarn Commandos' clandestine entry into the well-defended aerial stronghold belonging to Imperial governor Nistola, and their subsequent securing of his submission, Garret successfully deployed his troops, seizing the capital without any shots being fired.
