29th Division re-embarked at Alexandria and landed at Cape Helles on the Gallipoli Peninsula at 07.00 on 25 April 1915. IV Highland Mtn Bde and its two batteries served through the difficult opening weeks of the campaign with 29th Division, including the 1st, 2nd and 3rd Battles of Krithia and the Battle of Gully Ravine, before transferring to 11th (Northern) Division on 29 July. The 11th was a newly arrived formation of 'Kitchener's Army' volunteers recruited since the outbreak of war. It was concentrating on the island of Imbros for a fresh landing on the peninsula at Suvla Bay, which was carried out on 7 August. This landing was no more successful than the first, and the campaign bogged down again. Once at Suvla the Argyll Battery transferred to the command of another Kitchener formation, the 10th (Irish) Division, on 8 August, followed by the rest of the brigade on 13 August.
