The opportunity for a swift victory at Chunuk Bair had been lost. With the failure of attack of the Nek and the realisation that Chunuk Bair was in danger of being overrun, the Ottomans reinforced the peak. At 7:30 am, the New Zealanders were just away from the summit, but Ottoman and German reinforcements started arriving in heavy numbers. The commander of the Ottoman 9th Division, German Lieutenant-Colonel Hans Kannengiesser, had reached the summit and was preparing its defence. Kemal, the Ottoman colonel who had warned of the possibility of an attack, arrived soon after Kannengiesser. He ordered several regiments to the area. By 10:00 am, the peaks had around 500 Ottoman reinforcements, whereas only hours ago, there had been just 20 sleeping soldiers. However, these reinforcements were spotted by Australian artillery observers, who pinned down movements by the Ottomans, some of whom fled down from the summit to better cover.
