The 1st and 2nd Brigades, then the New Zealand and Australian Division, landed on the beaches around Ari Burnu but became entangled, which took time to reorganise. About four hours after the landings began, the bulk of the 1st Australian Division was ashore safely and its leading elements were pushing inland. By mid-morning Kemal had reorganised the defenders for a counter-attack on the commanding heights of Chunuk Bair and Sari Bair. The right flank of the small lodgement taken by the Australians was driven in at with most of being lost. During the afternoon and evening the left flank was pushed back from and the Nek. By evening, Bridges and Godley recommended re-embarkation; Birdwood agreed but after advice from the navy that re-embarkation was impossible, Hamilton ordered the troops dig-in instead. The Ottoman counter-attack was eventually repulsed and the Australians established a perimeter roughly from Walker's Ridge in the north to Shell Green in the south. ANZAC casualties on the first day numbered around killed or wounded. The failure to secure the high ground led to a tactical stalemate, with the landings contained by the defenders in a perimeter less than long.
