Nightly air raids on the island, a reported periscope sighting, and bomb explosions on Betio marked the tense days that followed. "Thuban" continued unloading cargo and supplied fuel and repairs for her own boats and those of other ships. "Thuban" lost three men to enemy action during this operation, and four of her landing craft were sunk as they moved toward the beach. Shore parties sent her a number of casualties which taxed her limited medical facilities. Discharging cargo on call, "Thuban" remained off Betio until 27 November, when she departed the Gilberts in company with Task Group (TG) 53.8 and headed for the Hawaiian Islands.
