patients and identified it as also part of K76A. By this time all companies were discovering enemy signs and having contacts. On the same day W Company, which was patrolling north-east of the Song Rai River, located a large enemy camp with 25–28 VC and at first light on 12 December attacked the group with one VC killed while the remainder escaped. A Company successfully scaled the western side and were able to establish a fire support base on the summit. On 16 and 17 December D Company located the K76A pharmacy, dental post and orderly room. There they recovered a huge supply of medical drugs. On 19 December, V Company discovered the major part of the hospital, a 200-bed complex complete with underground pharmacy, operating pits and convalescing wards. An enormous cache of medical supplies, food, tools, and equipment were found at the hospital and a large weapons cache was discovered nearby. Over the next week, all rifle companies conducted day and night search and destroy missions in their areas until 29 December 1969. Four Australians were killed with none wounded during the operation. There were no New Zealand casualties. VC killed numbered 22 with 5 wounded and 21 prisoners, 14 of whom had been patients of the K76A Hospital. Between D Company's and V Company's finds, approximately 1.5 tonnes of pharmaceuticals had been captured, thought to be the largest amount ever seized in the war by allied forces.

As a consequence of the overall US strategy of Vietnamization and with the Australian government keen to reduce its own commitment to the war, 8 RAR was not replaced at the end of its tour of duty. 1 ATF was again reduced to just two infantry battalions, albeit with significant armour, artillery and aviation support remaining. One of the New Zealand infantry companies—W Company—was also withdrawn at this time. Australian combat forces were further reduced during 1971 as part of a phased withdrawal. The Battle of Nui Le on 21 September proved to be the last major battle fought by Australian and New Zealand forces in the war, and resulted in five Australians being killed and 30 wounded. The New Zealand SAS troop was withdrawn in February and the artillery battery in
