 Today, the date of the initial landings, 25 April, is a public holiday known as Anzac Day in Australia and New Zealand and every year thousands of people gather at memorials in both nations, and indeed in Turkey, to honour the bravery and sacrifice of the original Anzacs, and of all those who have subsequently lost their lives in war.After the Gallipoli Campaign, Australian troops returned to Egypt and the AIF underwent a major expansion, which involved the raising of another three infantry divisions—the 3rd, 4th and 5th—and the establishment of the Anzac Mounted Division.In March 1916, the infantry began to move to France while the cavalry units stayed in the area and fought Turkish troops and the Senussi Arab tribes that were threatening British control of Egypt.
