<P> Allocated the northern landing, Birdwood's force included the 1st Australian Division (Major General William Bridges) and the New Zealand and Australian Division (Major General Sir Alexander Godley), a force of about 25,000 men . The force was to land and advance inland to cut the lines of communication to the Ottoman forces in the south . The 1st Australian Division would land first, with the 3rd Infantry Brigade first as a covering force moving inland to establish positions on Gun Ridge . The 2nd Infantry Brigade was to follow and to capture the higher ground on Sari Bair . The 1st Infantry Brigade would land last as the divisional reserve . The New Zealand and Australian Division was to come ashore and form up to advance across the peninsula . The force was to assemble at night and land at dawn to surprise the defenders and on the evening of 24 April, the covering force embarked on battleships and destroyers, with the follow on forces in on transports . The troops would disembark from the transports into ships' boats and be towed close to the shore by steamboats and then row ashore . </P> <P> At 04: 00 on the morning of 25 April the first wave of troops from the 3rd Brigade began moving towards the shore on lighters and the ships' boats . The covering force landed approximately 1.2 miles (2 km) too far north, in a bay just south of Ari Burnu, due to undetected currents or a navigational error . The landing was more difficult, over ground which rose steeply from the beaches, unlike the objective to the south, which was more open . The landing site was garrisoned by only two Ottoman companies but from positions on commanding ground the Ottomans inflict numerous casualties on the Australians before being overcome . The broken terrain prevented a coordinated drive inland, with the Australians on unfamiliar ground and with inaccurate maps . In the maze of steep ravines, spurs and dense scrub, Australian parties that got forward quickly lost contact and were broken up into small groups . Some Australian troops reached the second ridge but fewer still reached their objectives and having become dispersed, the covering force could provide little support to the follow - up force . </P> <P> 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 10: 30 a.m., with most of 400 Plateau being lost . During the afternoon and evening the left flank was pushed back from Baby 700 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 2,000 men 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 1.2 mi (2 km) long . </P> <P> The Australian submarine HMAS AE2 (Lieutenant Commander Henry Stoker) penetrated the Straits on the night of 24 / 25 April . As landings began at Cape Helles and Anzac Cove at dawn on 25 April, AE2 reached Chanak by 06: 00 and torpedoed a Turkish gunboat believed to be a Peyk - i Şevket - class cruiser and evaded a destroyer . The submarine ran aground beneath a Turkish fort but the Ottoman gunners could not bring their guns to bear and AE2 was manoeuvred free . Shortly after refloating, the periscope was sighted by a Turkish battleship firing over the peninsula at Allied landing sites and the ship ceased fire and withdrew . AE2 advanced toward the Sea of Marmara and at 08: 30 Stoker decided to rest the boat on the seabed until nightfall . At around 21: 00, AE2 surfaced to recharge batteries and sent a wireless report to the fleet . The landing at Cape Helles was going well but the landing at Anzac Cove was not as successful and the Anzac commander, Lieutenant General Sir William Birdwood, contemplated the re-embarkation of his troops . The success of AE2 was a consideration in Birdwood deciding to persist and reports about AE2 were relayed to the soldiers ashore to improve morale . Stoker was ordered to "generally run amok" and with no enemies in sight, he sailed into the Sea of Marmara, where AE2 cruised for five days to give the impression of greater numbers and made several attacks against Ottoman ships, which failed because of mechanical problems with the torpedoes . </P>
