The landing at Anzac Cove on Sunday, 25 April 1915, also known as the landing at Gaba Tepe and, to the Turks, as the Arıburnu Battle, was part of the amphibious invasion of the Gallipoli Peninsula by the forces of the British Empire, which began the land phase of the Gallipoli Campaign of the First World War.
The assault troops, mostly from the Australian and New Zealand Army Corps (ANZAC), landed at night on the western (Aegean Sea) side of the peninsula. They were put ashore north of their intended landing beach. In the darkness, the assault formations became mixed up, but the troops gradually made their way inland, under increasing opposition from the Ottoman Turkish defenders. Not long after coming ashore, the ANZAC plans were discarded, and the companies and battalions were thrown into battle piecemeal and received mixed orders. Some advanced to their designated objectives, while others were diverted to other areas and ordered to dig in along defensive ridge lines.
Although they failed to achieve their objectives, by nightfall the ANZACs had formed a beachhead, albeit much smaller than intended. In some places, they were clinging onto cliff faces with no organised defence system. Their precarious position convinced both divisional commanders to ask for an evacuation, but after taking advice from the Royal Navy about how practicable that would be, the army commander decided they would stay. The exact number of the day's casualties is not known. The ANZACs had landed two divisions, but over two thousand of their men had been killed or wounded, together with at least a similar number of Turkish casualties.
Since 1916, the anniversary of the landings on 25 April has been commemorated as Anzac Day, becoming one of the most important commemorative dates for Australia and New Zealand. The anniversary is also commemorated in Turkey and the United Kingdom.
Background
The Ottoman Turkish Empire entered the First World War on the side of the Central Powers on 31 October 1914. The stalemate of trench warfare on the Western Front convinced the British Imperial War Cabinet that an attack on the Central Powers elsewhere, particularly Turkey, could be the best way of winning the war. From February 1915 this took the form of naval operations aimed at forcing a passage through the Dardanelles, but after several setbacks it was decided that a land campaign was also necessary. To that end, the Mediterranean Expeditionary Force was formed under the command of General Ian Hamilton. Three amphibious landings were planned to secure the Gallipoli Peninsula, which would allow the navy to attack the Turkish capital Constantinople, in the hope that would convince the Turks to ask for an armistice.
Intention
Lieutenant-General William Birdwood, commanding the inexperienced Australian and New Zealand Army Corps (ANZAC), comprising the Australian Division and two brigades of the New Zealand and Australian Division, was ordered to conduct an amphibious assault on the western side of the Gallipoli Peninsula. The New Zealand and Australian Division normally also had two mounted brigades assigned to it, but these had been left in Egypt, as it was believed there would be no requirement or opportunities to use mounted troops on the peninsula. To bring the division up to strength, Hamilton had tried unsuccessfully to get a brigade of Gurkhas attached to them. In total ANZAC strength was 30,638 men.
The location chosen for the operation was between the headland of Gaba Tepe and the Fisherman's Hut, to the north. Landing at dawn after a naval gunfire bombardment, the first troops were to seize the lower crests and southern spurs of Hill 971. The second wave would pass them to capture the spur of Hill 971, especially Mal Tepe. There they would be positioned to cut the enemy's lines of communications to the Kilid Bahr Plateau, thus preventing the Turks from bringing reinforcements from the north to the Kilid Bahr Plateau during the attack by the British 29th Division which would advance from a separate beachhead further south-west. The capture of Mal Tepe was "more vital and valuable than the capture of the Kilid Bahr Plateau itself."
Birdwood planned to arrive off the peninsula after the moon had set, with the first troops landing at 03:30, an hour before dawn. He declined the offer of an old merchant ship, loaded with troops, being deliberately grounded at Gaba Tepe. Instead, the troops were to travel in naval and merchant ships, transferring to rowing boats towed by small steamboats to make the assault.
