Operations Officer on the situation before departing to pick up A Company from their lines. Yet Jackson was reluctant to reduce the defences at Nui Dat, considering the attack a possible feint. Consequently, although Smith repeatedly pressed Townsend, there was a delay of more than an hour from when the relief force was ordered to ready themselves until Roberts was allowed to move. Townsend finally ordered the relief force to move at 17:30, having received Jackson's approval. A Company, 6 RAR and 3 Troop were on standby in the company lines and departed fifteen minutes later. With the route largely dictated by the terrain, the possibility of the relief force being ambushed concerned Townsend and Jackson, but given the dire situation, they saw no alternative, and considered it unlikely, given the ground had been covered by frequent patrols, the proximity of D Company's position to Nui Dat, the open country between the base and rubber plantation, and that it was not yet dark. With 5 RAR back at Nui Dat, Jackson ordered it to take over the defensive positions normally occupied by 6 RAR, while deploying a platoon to the 1st APC Squadron lines, and placing D Company, 5 RAR on one hour's notice to move if required. The remainder of the battalion prepared to repel any attack on Nui Dat or to pursue the VC if they withdrew. Meanwhile, after departing D Company's position, the two sections from 12 Platoon moved south towards the sound of firing heard approximately away. Unaware of the exact position of 11 Platoon, Sabben instead located the rubber tapper's hut previously assaulted by Sharp in the opening phases of the battle. As they advanced, they were forced to fight off an attack on their right flank, before eventually pushing forward another . By this time, the VC had succeeded in pushing behind 11 Platoon in an effort to outflank them, and a large force clashed with 12 Platoon as they attempted to come to their aid. Advancing from the north, two VC platoons then assaulted the Australians, who were now heavily engaged from three directions. Meeting a similar fate to 10 Platoon, Sabben's men were forced to ground short of their objective, and were themselves in danger of being encircled. Sustaining increasing casualties, they clashed with several groups of VC trying to move around their western flank to get between 11 and 12 Platoon
