 Within two hours half the Australian Division was involved in the battle of 400 Plateau . However , most of the officers had misunderstood their orders . Believing the intention was to occupy Gun Ridge and not hold their present position , they still tried to advance . The 9th and 10th Battalions had started forming a defence line , but there was a gap between them that the 7th Battalion was sent to fill . Seeing the 2nd Brigade coming forward , units of the 3rd Brigade started to advance to Gun Ridge . The advancing Australians did not then know that the counter @-@ attacking Turkish forces had reached the Scrubby Knoll area around 08 : 00 and were prepared for them . As the Australians reached the Lone Pine section of the plateau , Turkish machine @-@ guns and rifles opened fire , decimating the Australians . To the north other troops , advancing beyond Johnstone 's Jolly and Owen 's Gully , were caught by the same small arms fire . Soon afterwards a Turkish artillery battery also started firing at them . This was followed by a Turkish counter @-@ attack from Gun Ridge . Such was the situation they now found themselves in that at 15 : 30 McCay , now giving up all pretence of advancing to Gun Ridge , ordered his brigade to dig in from Owen 's Gully to Bolton 's Ridge .
