Relations between Ferreira de Carvalho and the Japanese deteriorated. His telegraph link with the Portuguese Government in Lisbon was cut. In June 1942, a Japanese official complained that the Governor had rejected Japanese demands to punish Portuguese officials and Timorese civilians who had assisted the "invading army" (the Australians). On 24 June, the Japanese formally complained to Lisbon but did not take any action against Ferreira de Carvalho. complimenting Sparrow Force on its campaign so far, and again asking that it surrender. The Japanese commander drew a parallel with the efforts of Afrikaner commandos of the Second Boer War and said that he realized it would take a force 10 times that of the Allies to win. Nevertheless, Doi said he was receiving reinforcements, and would eventually assemble the necessary units. This time Ross did not return to Dili, and he was evacuated to Australia on 16 July.
