 <unk> was at 19 : 00 and the Turkish attack had now reached Malone 's <unk> and The Nek . The New Zealanders waited until the Turks came close , then opened fire in the darkness , stopping their advance . <unk> outnumbered , they asked for reinforcements . Instead , the supporting troops to their rear were withdrawn and the Turks managed to get behind them . So , taking the machine @-@ guns with them , they withdrew off Russell 's Top into Rest Gully . This left the defenders at Walker 's Ridge isolated from the rest of the force .
