The Australian attack was led by the 3rd Brigade (including the 11th Battalion). After a week's heroic fighting (in which the 16th Battalion took a prominent part) under conditions never before experienced in warfare, and the loss of 9,000 killed, wounded, and missing, a position was made good which extended in an arc from the foot of Walker's Ridge, on the north, up to Russell's Top, across the head of Monash Gully, to MacLaurin's Hill, continuing to Bolton's Ridge and resecting the beach about 2,000 yards north of Gaba Tepe. The base of this arc measured about 2,700 yards and the enclosed area did not exceed three-quarters of a square mile. During the next three months the Corps was reinforced by various drafts, and four brigades of Light Horse dismounted. Attempts were made from time to time to improve and extend the Australian position, but little progress was made. At the same time the Turks were by no means idle for, apart from fortifying their positions, they frequently attacked in endeavours to drive us off their soil. The heaviest assault was on the 18th May when 30,000 fresh troops were flung at the 1st Division and the New Zealanders. So effectually were they repulsed that the Turks begged for an armistice for the purpose of collecting and burying the dead. Sir Ian Hamilton, who had been strengthened by several new divisions, planned a fresh attack for early in August. On the 6th of that month the 1st (N.S.W.) Brigade stormed Lone Pine. On the following morning attacks were made from Steel's Post, Quinn's Post, Pope's Hill, and Russell's Top, but all of these were unfruitful and caused heavy losses. The main attack in the Anzac sector was, however, delivered from the left. This commenced on the night of the 6th August and swept up the Sazli Beit and Chailak Deres,[J] over Big Table Top, Bauchop Hill, and Rhododendron Spur, to a position--afterwards called "The Apex"--within 400 yards of the summit of Chunuk Bair.[K] A portion of the force detailed for this advance moved up the Aghyl Dere and endeavoured to take Koja Chemin Tepe from the west side but, after many casualties, had to entrench on some of the under-features (Cheshire Ridge-Warwick Castle). During the progress of this fighting the IX. Corps made a fresh landing at Suvla Bay (6th-7th August). The combat was heavy and eventually a junction was effected with the Australian left, but not one of the real objectives was gained. The operations were continued until the 29th August, on which date the 10th Light Horse, sent north to reinforce there, stormed Hill 60. This was the last Australian attack on the Peninsula. Henceforth attention was given solely to holding and strengthening the positions gained. The 2nd Australian Division took no part in any of these operations, but one of its battalions--the 18th--arrived in time to join in the fighting for the hill feature just mentioned.
