In September, the "Titania" operated out of New Guinea where the U.S. Seventh Fleet was preparing for the coming assault on the Philippines. Early in October, she participated in exercises with Transport Division 6. Then, on Friday, 13 October, she headed for Humboldt Bay, the staging area for the impending invasion of Leyte. Assigned to the Palo Attack Group, the "Titania" entered Leyte Gulf on the morning of 20 October. At 08:45, the "Titania" began releasing her boats which carried supplies and equipment for the U.S. Army's 24th Infantry Division. At 14:00, she approached within two miles of the beach to facilitate unloading. Later in the afternoon, as the Army's Light Tanker No. 425 came alongside the "Titania" to help her unload, one of the tanker's machine guns accidentally discharged, shooting about 100 holes in the "Titania"s side and severing her degaussing cable in two places, but no serious damage resulted. On the next day, after discharging over 1,000 tons of cargo, the "Titania" departed from Leyte Gulf, returning to New Guinea on the 27th.
