Operation Hammersley , 10 February until 9 March 1970, was undertaken by a combined force of: C Company, 8th Battalion, the Royal Australian Regiment (8RAR); armoured personnel carriers from 3 Cavalry Regiment; tanks from 1 Armoured Regiment; sappers from the Royal Australian Engineers; a mortar section from 8RAR’s Support Company; air support, and even a Navy destroyer off-shore to provide gunfire support. The operation aimed to protect 17 Construction Squadron, Royal Australian Engineers, at a quarry in the western foothills of the Long Hai hills. The Long Hai hills were a stronghold for the Viet Cong, who used the caves there as a bunker complex and had planted many landmines and booby traps in the area. Over two fierce weeks, 8 RAR carried out patrols and conducted ambushes, engaging VC troops and eventually capturing the bunker system. However, it was a costly campaign. In total, over 70 Australians were killed or wounded during the operation. The worst day for mine casualties in Australia's war in Vietnam occurred on 28 February 1970. It became known as 'Black Saturday". Nine members of 8RAR were killed and 29 wounded.

In 1967, Brigadier Stuart Graham issued the calamitous order: First Australian Task Force would construct an 11 kilometre 'barrier fence and minefield' containing over 20,000 powerful M16 landmines in Phuoc Tuy Province, Southern Vietnam. The purpose of the 'barrier' was to separate and to shield the majority of the population in the south-west province from his enemy's regular forces in the north and east.australia. army. australian task force (vietnam), land mines -- phuoc tuy (vietnam : province), 8rar, 8 rar, operation hammersley, m16 landmines, brigadier stuart graham, operation pinaroo, operation leeton
