50th Anniversary of the Battle of Nui Le: 21 September 1971

Fifty years ago in September 1971, Australia had been involved in the Vietnam War for over nine years. With no end in sight to an unpopular war, the Australians – like the Americans – were reducing their forces as they prepared to pull out of Vietnam. The withdrawal would take time and would not be easy.

While Operation Overlord in June had forced the enemy to withdraw, by September Viet Cong and North Vietnamese Army forces were back in Phuoc Tuy Province, again looking to lure the Australians into a large-scale ambush to score a propaganda victory. The Australians would have to meet the challenge again.

Operation Ivanhoe was launched on 19 September. Three companies of the 4th Battalion, Royal Australian Regiment, including a company from the Royal New Zealand Infantry Regiment (4RAR/NZ), and one company of the 3rd Battalion, Royal Australian Regiment (3RAR) – supported by artillery, engineers, armoured personnel carriers (APCs) and helicopters from 9 Squadron, RAAF – were inserted near suspected enemy concentrations south-east of the Courtenay Rubber Plantation. But importantly, this time they had no tank support. As part of the staged withdrawal, 1 Armoured Regiment had recently departed Vietnam.

On 20 September an ambush and a series of contacts suggested the enemy was trying to provoke a reaction, luring the Australians into a well-prepared bunker system. The next morning, B Company, 4RAR/NZ came under mortar attack while patrolling south-east of the rubber plantation, suffering fifteen casualties. They then clashed with small parties of enemy in a series of fleeting firefights. As they continued patrolling the Australians saw more and more tell-tale evidence of an enemy presence. One officer remembered “… an uneasy feeling throughout the Battalion … a sense of foreboding”.

When D Company, four kilometres away, ran into an extensive bunker system and was pinned down by heavy fire, air support was called in and the enemy position was pounded for four hours. That afternoon the company pushed forward again but were immediately forced to ground by withering fire. Looking to extricate themselves, the Australians unwittingly withdrew into a more precarious position within the bunker system. Trapped, surrounded, with reduced artillery support and no tanks, they were forced to rely on US airstrikes and RAAF helicopter gunships to keep the enemy at bay. 

Running low on ammunition, D Company was in dire straits as casualties continued to mount. Artillery support kept them alive throughout the night, landing as close as 50 metres from where they lay. Some expected the enemy to attack at dawn to finish them off, but it never came. In the morning the enemy was gone; the battle of Nui Le was over.

Nui Le was the last major enemy engagement by Australian troops in Vietnam. The five killed in action there were the last Australian soldiers to die in combat in Vietnam. For their bravery under fire, seven Australians were recognised with awards. Operation Ivanhoe concluded on 2 October. The following month, Nui Dat base was handed to the South Vietnamese and by December nearly all Australian troops had left Phuoc Tuy Province.

We remember those who fought in that battle 50 years ago. We pay our respects to those who died, and to the survivors who returned home.
