The advance entered Palestine and an initial, unsuccessful attempt was made to capture Gaza on 26 March 1917, while a second and equally unsuccessful attempt was launched on 19 April. A third assault occurred between 31 October and 7 November and this time both the ANZAC Mounted Division and the Australian Mounted Division took part. The battle was a complete success for the British, over-running the Gaza–Beersheba line and capturing 12,000 Turkish soldiers. The critical moment was the capture of Beersheba on the first day, after the Australian 4th Light Horse Brigade charged more than . The Turkish trenches were overrun, with the Australians capturing the wells at Beersheba and securing the valuable water they contained along with over 700 prisoners for the loss of 31 killed and 36 wounded. Later, Australian troops assisted in pushing the Turkish forces out of Palestine and took part in actions at Mughar Ridge, Jerusalem and the Megiddo. The Turkish government surrendered on 30 October 1918. Units of the Light Horse were subsequently used to help put down a nationalist revolt in Egypt in 1919 and did so with efficiency and brutality, although they suffered a number of fatalities in the process. Total Australian battle casualties in the campaign were 4,851, including 1,374 dead.
