 The New Zealand riflemen soon gained a footing on Mount Royston , aided by accurate and rapid shooting from the Somerset Royal Horse Artillery Battery . By 16 : 00 , the attack had proceeded to a point where Chaytor arranged with the 5th Mounted Brigade for a squadron of Royal Gloucestershire Hussars and two troops of the Worcestershire Yeomanry to gallop against the southern spur of Mount Royston . They easily took the spur , the defenders not waiting for the <unk> of the mounted charge . From the crest of the spur , the Gloucestershire squadron shot down the horse teams of an Austrian , German or Ottoman battery of pack guns concentrated in the hollow behind the spur , and the attacking force began to surrender . The New Zealand Mounted Rifle and 5th Mounted Brigades were supported by leading infantry battalions of the 127th ( Manchester ) Brigade ( which had just arrived ) when Ottoman and German soldiers began to surrender en <unk> . At about 18 : 00 , 500 prisoners , two machine guns and the pack battery were captured , and the outer flank of the attacking force was completely routed .
