While most Australian units in the Pacific Theatre fought in the SWPA, hundreds of Australians were posted to British units in Burma and India. These included 45 men from the 8th Division who volunteered to train Chinese guerrillas with the British Mission 204 in southern China and served there from February to September 1942. Hundreds of Australians also served with RAF units in India and Burma, though no RAAF units were deployed to this theatre. In May 1943, some 330 Australians were serving in forty-one squadrons in India, of which only nine had more than ten Australians. In addition, many of the RAN's corvettes and destroyers served with the British Eastern Fleet where they were normally used to protect convoys in the Indian Ocean from attacks by Japanese and German submarines.
