On the afternoon of August 18, 1966, Major Harry Smith and 108 mostly inexperienced Australian and New Zealand soldiers find themselves cut off in a rubber plantation in South Vietnam called Long Tan, facing an estimated 2,500 Viet Cong and North Vietnamese troops. The film reconstructs the three and a half hours that follow: driving monsoon rain, ammunition running low, shattered trees, and a company holding a defensive line while artillery and reinforcements try to reach them. Narrated by Sam Worthington, it combines archival material and interviews to lay out how the engagement unfolded and why it became one of the costliest single actions in Australian military history, with 18 Australians killed against several hundred enemy dead. The account also covers the aftermath, including the Presidential Unit Citations later awarded by the United States and South Vietnam. First broadcast on the History Channel in August 2006, the film later won Most Outstanding Documentary at the 2006 ASTRA Awards.
