Mustafa Kemal issued his order, "I do not expect you to attack, I order you to die! In the time which passes until we die, other troops and commanders can take your place!". and later noted the 57th Regiment was "a famous regiment this, because it was completely wiped out".

When the ANZAC first landed they encountered small bodies of Turks who, after doing what they could, withdrew back over the ridges. The main Ottoman forces in the area had been held in reserve to see just where the British Empire troops were going to land on the peninsula. By 6.30 am a report had reached the commander of the 19th Division of the Ottoman Army, Yarbay Mustafa Kemal, that an enemy force had scaled the heights at Ari Burnu. Mustafa Kemal's troops were at Bigalı, a small village off to the east beyond the main range, and he ordered his whole division to prepare to march to the coast. He himself set off riding at the head of the 57th Regiment. By about 9.30 am Mustafa Kemal stood at Chunuk Bair with some other officers. He could see the British warships and transports off Anzac Cove and also, coming rapidly up the hill towards him, a group of Ottoman soldiers who had been tasked with defending Hill 261 (Battleship Hill).
