During September the main body of the Japanese 48th Division began arriving to take over the campaign. The Australians also sent reinforcements, in the form of the 450-strong 2/4th Independent Company—known as "Lancer Force"—which arrived on 23 September. The destroyer ran aground at the southern port of Betano while landing the 2/4th, and had to be abandoned after it came under air attack. The ship's crew was safely evacuated by and on 25 September 1942 and the ship destroyed by demolition charges. On 27 September, the Japanese mounted a thrust from Dili towards the wreck of "Voyager", but without any significant success.
