The Australia and New Zealand Army Corps landed at a small bay (now known as Anzac Cove) north of Kabatepe on the Gallipoli peninsula on 25 April 1915. Their objective was to seize part of the Sari Bair range to cover their advance across the peninsula to cut the Turkish supply lines and threaten Turkish forces fighting further south at Cape Helles.
The Anzacs were never meant to land at the cove, with its steep hinterland of rough gullies. They should have landed on a much longer beach and on a wider front, but it seems that a navigational blunder put the troops ashore in the wrong place.
Australian troops went ashore first, and the New Zealanders followed from late morning, pushing inland to join Australians who had reached the second ridge (and in some cases to the third ridge) - about 2 km from the bay. They struggled in the rugged terrain, and found themselves under increasing pressure from the Turkish defenders.
By the end of the day the situation was so bleak that proposals were made for the evacuation of the troops. But this was impracticable, and the Commander-in-Chief, Sir Ian Hamilton, urged the Anzacs to dig in. This they did, establishing a tenuous line of outposts along the second ridge. The troops depended on supplies landed at Anzac Cove, which was the hub of the Anzac effort.
For many years Anzac Day ceremonies were held at Ari Burnu Cemetery on the northern point of Anzac Cove. The number of people attending grew so large that an Anzac commemorative site was created a few hundred metres to the north, facing North Beach. It was opened on Anzac Day 2000.
