This was the new battalion's first shake-down operation and took the form of an airmobile move to search the Binh Ba Rubber Estate 15 miles north of Nui Dat, and to check the identity of workers in the area - really a show of force. The operation was not completed until dusk because of the heavy undergrowth encountered by D Company during their approach. The battalion flew back to Nui Dat, being extracted from two LZs, the last lift taking place in total darkness.
This was 4 RARs final acclimatisation operation prior to taking part in Task Force operations. The task was to destroy all enemy and enemy assets in the area between the Nui Dinh and the Nui Thai Vai (mountains), south-west to Route 15. W Company, patrolling down the eastern boundary, met stiff opposition from caretaker groups but managed to reach the installations being guarded.
There were five contacts with the enemy and one member of the Company was wounded by an enemy claymore mine. A number of large camps were located and destroyed, where possible, including a battalion sized training camp and a camp some 200 yards in width. Many weapons, packs, ammunition and a large quantity of food were captured. W and D Companies moved to a pick-up point on Route 15 and returned to Nui Dat by road on 20 June for two days' rest.
The enemy was expected to try to attack the area of Long Binh (near Saigon) for their mid-year offensive. It was decided to use 1 Australian Task Force to relieve the US 199th Light Infantry Brigade with the task of dominating the rocket belt to the north-east in order to protect the huge storage areas from rocket attack. The ANZAC Battalion deployed by air from Nui Dat on 23 June to a position on the left flank of 1 RAR. During patrolling, W company had only one contact with the enemy when a group of four detonated a claymore mine against a 2 Platoon patrol. Two possible rocket launching sites were located. In the latter stages of the operation the Company assumed responsibility for the protection of the Fire Support Base.
The operation was successful in that no rockets were fired from the Task Force area, but, as there was little sign of any large enemy concentrations, the ANZAC Battalion was air-lifted to Fire Support Base Chestnut ( near the village of Thai Thien on Route 15) to commence another operation - Operation Merino.
Operation Merino was a battalion-sized reconnaissance in force in the western part of the enemy zone known as the Hat Dich. The enemy considered himself relatively safe and carried out training and operational planning in the area. W Company was initially the Fire Support Base Company with additional responsibility for an adjoining AO. By late afternoon there had been several small contacts and D Company never cleared W Company's AO for the duration of the operation, so the Company initially had a quiet time.
On 20 July the Fire Support Base was moved further into the area, some 4,000 metres from Route 15. On 22 July V Company located what appeared to be a sizeable number of enemy in a bunkered camp. Two platoons were committed but returned to the company base as light faded. The next day V Company again returned to the camp and came under heavy fire. The company then withdrew to allow for air strikes, but darkness prevented a return to the scene. That night the first battalion attack since the Korean War was planned. The attack was preceded by a further air strike and heavy bombardment by two batteries of 105mm and one battery of 155mm guns. Because of long delays in getting the assault companies to the Start Line through the thick undergrowth, the bombardment was prolonged considerably. W Company was left assault company with B Company on the right and C Company, 1RAR, in reserve. (C Company 1 RAR just happened to be passing by in-route to Nui Dat.) The attack went in but the defended position had been vacated. (Just as well as the OC W Company, the CSM and a signaller were the first to step from the jungle into the completely flattened enemy position.) The scene was one of complete devastation - not a tree or leaf was to be seen on the surface, but many of the bunkers were still intact. The enemy had flown.
The operation ended on 25 July and all companies returned to Nui Dat by air after 33 days continuous operations. From 25 to 31 July W Company remained in Nui Dat preparing for Operation Lyrebird
Keen to return to the Nui Dinh mountains, an active area for the enemy, the Officer Commanding volunteered to command another land clearing operation. The trail to be cleared was between the Nui Thai Vais and the Nui Dinhs in AO Warburton, clearing from Route 15 to the north.
Initially W Company deployed along Route 15 in APCs with Engineers of 17 Construction Squadron, a Land Clearing Team, and a section of Mortars. Two Fire Support Bases were used during the operation - Hague and Hokonui. These were within range of the guns in Nui Dat. Generally, the APCs and one platoon provided protection for the engineers, a platoon patrolled well out from the cut, and the third platoon rested and protected the Fire Support Base. The enemy reacted quite vigorously to the operation so elements of B Company later joined W Company to provide greater flexibility in the active patrol programme. On 4 August, the enemy fired automatic weapons and rockets at sentries on the perimeter of Hague and badly damaged two bulldozers. (One bulldozer was buried to extinguish the fire!) Two members of the Company were injured. On 12 August a platoon on patrol made contact with five Viet Cong who quickly withdrew. On the follow up an enemy camp was located which contained a large quantity of ammunition and supplies hidden deep in a tunnel system. During the search of the camp two enemy walked in, one was killed and the other escaped. Although many signs of the enemy presence were picked up and trails followed, it was not until 29 August that an estimated ten enemy were sighted and engaged with artillery and mortar fire with unknown results. Also on the 29th an enemy hutted camp of fourteen huts and cookhouse was located and destroyed.
The operation lasted five weeks and in that time a trail through the jungle some 200 metres wide and 13,500 metres long was cleared, This was an excellent result considering the heavy rain reduced the area to deep mud and stinking slush. One night, while at Fire Support Base Hokonui, the Command Post had to be vacated as it turned into a swimming pool! W Company returned to Nui Dat on 4 September to prepare for Operation Innamincka.
Operation Innamincka started with a battalion cordon and sweep of Nui Nhan (Hill) against a suspected enemy camp. Three companies were to move into blocking positions during darkness, W Company across the North end of the feature, and B Company was to sweep from the South. Only V Company had minor contacts during the move in, killing one local Viet Cong and wounding another
When B Company moved on to the hill there was neither sight nor sound of an enemy - in fact there was no concrete evidence that he had ever been there. Companies then commenced sweeping to the south-west. Only W Company made contact with the enemy, engaging 10 enemy in a camp. The enemy withdrew, apparently without loss, but left a large amount of ammunition, weapons and supplies behind. The operation concluded on 12 September with a fly-out to a new AO for Operation Hawkesbury.
Operation Hawkesbury, a reconnaissance in force, was one of 4 RAR/NZ (ANZAC) Battalion's most successful operations. It was carried out in three stages.
Initially the battalion moved into blocking positions east of Route 2, on the western edge of the enemy zone known as the Thua Tich. B and C Companies swept westwards while W Company went south-west to search for likely trails being used by enemy supply parties. Little was seen by W Company on the first day (Friday the 13th), but C Company came into contact with enemy in bunkers and there were 10 casualties -three of them fatal.
As the result of intelligence indicating a likely consignment of rockets being moved from east to west, W Company was unexpectedly uplifted by helicopter (and V Company from the Fire Support Base by APCs) and moved north into the Don Dien de Courtenay rubber plantation early on the 14th. Soon after dispersing from the LZ a platoon had a clash with an unknown sized group of enemy deployed along a stream bed. A member of the platoon, Pte BJ Petersen, was killed by a sniper in a concealed hole in the ground during a search of the area. Later that day there was another clash with two enemy and another with three the following day.
While V Company moved into blocking positions on the western edge of the rubber, W company began a detailed search of the area of the stream bed, Gradually a complex system of tunnels was revealed containing tons of supplies for the Viet Cong, including medical supplies and ample new US Army torches to equip both V and W Companies! Leaving the find to the engineers to destroy, both V and W Companies were uplifted by helicopter to re-join the rest of the battalion who had moved to a new AO. The new AO was Canowindra and all companies had productive contacts. While approaching the W Company LZ ,Viet Cong were sighted on the jungle edge but it was decided to land. A fire-fight developed immediately with a group of about eight enemy and at least two were killed. On the follow up, blood trails were lost as the light failed. That night, a lone enemy approached Company headquarters but quickly withdrew into the darkness before a shot was fired.
V Company killed ten enemy in two days, while C Company killed four Viet Cong withdrawing from a camp being attacked by B Company. C Company later attacked a camp of 150 bunkers killing at least two Viet Cong. A large amount of equipment, including two 122mm rockets and detailed maps of all major installations throughout South Vietnam, were captured. Documents indicated that the battalion was in the area of the headquarters of 84 Rocket Regiment. W Company continued patrolling with no further contacts but located many fortified areas which had been recently vacated. A platoon even reported finding some elephant tracks which led to much speculation on the mode of transport being used by the Viet Cong!
All companies returned to Nui Dat by air on 24 September well satisfied with the results of the operation.
As there was no immediate operation planned, W Company made it known that they wished to return to an area where well worn tracks had been located on a previous operation, but not checked out. On 28 September W Company, with a section of mortars and supported by the guns from Nui Dat, mounted an independent operation in the area of Ngai Giao (AO Mustang), on Route 2 north of Nui Dat. The Company established its own Fire Support Base and patrolled from it. At times all platoons were out of the base on patrol, protection being provided by Company Headquarters and a few "light duty" members from each platoon.
There were two platoon contacts on the 30 September, resulting in one enemy being captured. There were three clashes on 2 October: the first with a party of four which resulted in one being killed and possibly two wounded; the second with a party of ten when six were killed and at least two wounded; the third with a group of three who succesfully broke contact and withdrew. On the 5th of October the last clash was with a party of three enemy resulting in one being killed.
The Company returned to Nui Dat on 6 October to undertake base defence duties and to prepare for Operation Capital.
Operation Capital was a two-phased two-battalion-sized reconnaissance in force operation back in the Thua Tich area - the home of an enemy Rear Services Group. The ANZAC Battalion deployed on the morning of 13 October to a LZ near the deserted hamlet of Ap Xa Bang. W Company and 104 Battery established Fire Support Base Flinders on the edge of the de Courtenay rubber estate.
W Company provided protection of the Fire Support Base and conducted local patrols until 30 October when Phase I concluded and the battalion flew back to Nui Dat. After 3 days the battalion, less W Company, returned to the same area hoping to surprise the enemy. W Company prepared for the return to 1 RNZIR in Malaysia and acted as Sick Ward for the battalion for those with mild cases of malaria which was rampant in the Task Force.
