Crossfire Hurricane: the Battle of Long Tan deals with the largest battle fought by the Australian Forces in South Vietnam. Occurring in August 1966, a patrol of the 6th Royal Australian Rifles (RAR) surprised a large force of Viet Cong (NLF) moving to attack the Australian base at Nui Dat. The ensuing firefight, fought at times in the midst of a monsoon-like deluge, lasted nearly 4 hours. At some points in the battle the Australians were out-numbered by almost six times their number, and fighting in some places was hand-to-hand.
