 While radio direction finding suggested it may have been near Phước Tuy's northern border, three weeks earlier it had been reported close to the western side of the Australian TAOR, and one of its battalions had (incorrectly) been believed involved in an attack on Phú Mỹ in the south-west of the province on 11 August.Consequently, Jackson reasoned that if the battle unfolding near Long Tân was the opening phase of an attack on Nui Dat, the main assault was still to come, and he would need the bulk of his forces to defend the base.He considered the commitment of A Company would tie up the bulk of 6 RAR and the artillery.
