The 10th (Irish) Division was formed under the first 100,000 of Kitchener ‘New Army’.
It was commanded by Lt. Gen Sir Bryan Mahon KCVO DSO.
The Division included:
6th Bn Royal Irish Rifles
5th Bn Connaught Rangers
6th Bn Leinster Regt
10th Bn Hampshire Regt
6th & 7th Bn Royal Dublin Fusiliers
6th & 7th Bn Royal Munster Fusiliers
5th & 6th Bn Royal Inniskilling Fusiliers
5th & 6th Bn Royal Irish Fusiliers
Artillery, Engineer, Army Service Corps and Medical units came from Scotland and England.
After training in Ireland, the Division moved to Basingstoke in May 1915 and on, 1st July 1915, was ordered to embark for Gallipoli.
On 6th August 1915, the detached 29th Division landed at ANZAC Cove with Australian and New Zealand forces, while the remainder of the 10th (Irish) Division (30th & 31st Brigades) landed further north at Suvla Bay.
Militarily, the campaign was a shambles, but the soldiers fought bravely under very difficult conditions – heat, thirst, hunger, flies, and the ever-present stench of the unburied bodies, which lay in ravines throughout the battlefield. Battles continued through August, but by September both sides were content to hold their lines, until the Allies evacuated on 19-20 December 1915. Some 3,500 10th (Irish) Division officers and men lost their lives in the Gallipoli campaign.
However, the 10th (Irish) Division was withdrawn from Gallipoli on 30th September, re-deployed to Salonica and remained there for two years, taking part in the Battle of Kosturino.
In September 1917, the Division was moved from Macedonia to Egypt, and on to Palestine. It took part in the 3rd Battle of Gaza and the Capture of Jerusalem.
Following the March 1918 German Spring Offensive on the Western Front, all but one of the 10th Division’s British battalions were transferred to France and replaced with Indian troops; the Division ceased to be ‘Irish’. It remained in Palestine until the end of the war with Turkey on 31st October 1918.
