 With the PVA eager to gain a last-minute victory over the UN forces and the tactical advantage offered to the side that held The Hook after the truce, simultaneous attacks were soon launched against 2 RAR and the 7th Marine Regiment on the left flank, in two major actions on the nights of 24/25 and 25/26 July.On the evening of 24 July a 50-strong PVA force probed 2 RAR's forward outposts after dark, attacking C Company on Hill 121 and surrounding a bunker on the left flank, while the Marines had a similar contact on the left flank.A forward Australian standing patrol from D Company subsequently clashed heavily with the PVA probe, losing five wounded before directing tank and artillery fire which dispersed their attackers.
