The brigade, including 2/3rd Londons returned from Khartoum, assembled at Abbassia Camp in Cairo and prepared to reinforce the Mediterranean Expeditionary Force fighting at Gallipoli. However, the brigade did not proceed as a complete formation, the battalions proceeding individually. The 2/1st and 2/3rd Battalions were the first to go, in September, being sent via Mudros to reinforce the Regulars of the 29th Division. The 2/3rd Londons landed at Suvla Bay on 23 September and were attached to 88th Bde in the 'Dublin Castle' Sector for training, with A Company attached to the 2nd Bn Royal Fusiliers. 2/1st Londons landed at W Beach, Suvla, about midnight on 24 September, and were attached to 88th Brigade. On arrival they were re-armed with modern Short Lee-Enfield rifles (other battalions of the brigade retained their obsolete Long Lee-Enfields) and then moved forward to the Brigade Reserve Area. The battalion was attached to the 1st Bn Essex Regiment for training. After training in trench warfare the two battalions began tours of duty in the front line; the 2/1st Bn alternated with the Newfoundland Regiment on a weekly rotation at Essex Ravine.
