After a period spent in the canal defences, the battalion embarked on SS "Nile" at Alexandria between 1 and 6 May 1915 for the Gallipoli Peninsula and disembarked at 'W' Beach at Cape Helles, where Allied troops had landed a few days earlier. The Lancashire Fusilier Brigade was the first part of the division to go into action, temporarily attached to the 29th Division for the Second Battle of Krithia on 6 May. The 1/7th supported an attack by the 1/6th Bn and the following day moved forward through the captured line, but was forced to retire after two attempts to take Gurkha Bluff. The battalion was relieved at sundown.
