Australian special forces played a significant role in the Pacific War. Following the outbreak of war commando companies were deployed to Timor, the Solomon and Bismarck islands and New Caledonia. Although the 1st Independent Company was swiftly overwhelmed when the Japanese invaded the Solomon Islands in early 1942, the 2/2nd and 2/4th Independent Companies waged a successful guerrilla campaign on Timor which lasted from February 1942 to February 1943, when the Australian force was evacuated. Other commando units also played an important role in the New Guinea, New Britain, Bougainville and Borneo campaigns throughout the war where they were used to collect intelligence, spearhead offensives and secure the flanks of operations conducted by conventional infantry.
