In August, the Japanese 48th Division—commanded by Lieutenant General Yuitsu Tsuchihashi—began arriving from the Philippines and garrisoned Kupang, Dili and Malacca, relieving the Ito detachment. Tsuchihashi then launched a major counter-offensive in an attempt to push the Australians into a corner on the south coast of the island. Strong Japanese columns moved south—two from Dili and one from Manatuto on the northeast coast. Another moved eastward from Dutch Timor to attack Dutch positions in the central south of the island. The offensive ended on 19 August when the main Japanese force was withdrawn to Rabaul, but not before they secured the central town of Maubisse and the southern port of Beco. The Japanese were also recruiting significant numbers of Timorese civilians, who provided intelligence on Allied movements. Meanwhile, also in late-August, a parallel conflict began when the Maubisse rebelled against the Portuguese.
