On 6 August, the battalion held off a fierce Turkish counterattack on the trench, which became known as "Leane's Trench" during the Battle of Lone Pine. Heavy casualties were sustained on both sides. The battalion suffered 41 killed, 94 wounded and 19 missing. By the end of the month, the 11th Battalion's strength, despite having received six batches of reinforcements, had fallen to just over 500 men, approximately half its authorised strength. The following month, command of the battalion passed to Leane when Lyon-Johnston took over as brigade commander. As the health of the men deteriorated, the battalion's strength fell further to just over 300. The arrival of winter in October brought heavy rain and even harsher conditions.
