 Dug-in to the east, 16 RNZA had been forced to fire with minimum crest clearance over the Australian lines in order to bring effective fire to bear on the assaulting PVA from their 25-pounders.Using both variable time proximity and time-set fuses, the New Zealand gunners used air bursts to break up the PVA assaults, causing heavy casualties.Despite the risk of causing casualties among their own soldiers no serious casualties were incurred by the Australians, although one suffered a broken shoulder after a brass nose cone from a faulty time-of-flight fused shell exploded over his position.
