The 1/5th (QER) Battalion, Royal Scots, joined 88th Bde in 29th Division at Leamington on 11 March 1915. It was the only TF battalion in what was otherwise a Regular Army formation composed of battalions brought back to the UK from around the British Empire following the outbreak of war. The battalion entrained for Avonmouth Docks on 21/22 March where it embarked on the "Caledonia" and the "Melville" and sailed via Malta to Alexandria where it disembarked on 2 April and went into camp. It re-embarked on 6 April aboard the "Dongola", "Haverford", "Kingstonian", "Marquette", and "Melville" for Mudros, where it joined the British forces gathering for the Landing at Cape Helles. After lying anchored off Tenedos the force began landing at 07.00 on 25 April. Two companies of 1/5th Bn landed at V Beach at 12.30 without casualties and moved forward to the support trenches. The other two companies landed later to provide working parties on the beach, unloading stores under fire and suffering casualties. One of the advanced companies was moved up into the firing line on 26 April and the battalion joined in the general advance against Achi Baba Ridge the following afternoon. By 08.00 on 28 April the battalion had suffered heavy casualties, including the CO, Lt-Col J.T.R. Wilson wounded, and had to be withdrawn from the advanced positions. The battalion was moved to the left where it began building a redoubt, and then moved back to reserve positions.
