First World War
The Connaughts fielded 6 battalions and lost approximately 2,500 officers and other ranks during the course of the war.[3] Two battalions of the regiment were formed as part of Secretary of State for War Lord Kitchener's appeal for an initial 100,000 men volunteers in 1914.
In 1919, the 2nd Battalion was reformed, by redesignation of the 5th (Service) Battalion.[6] And in 1921, the Special Reserve reverted to its militia designation.
Following the establishment of the Irish Free State in 1922, the regiment disbanded, along with the other five regiments that had their traditional recruiting grounds in the counties of the new state.[7]
^Murphy, p. 30 quote: "Following the treaty that established the independent Irish Free State in 1922, it was decided to disband the regiments that had their traditional recruiting grounds in southern Ireland: The Royal Irish Regiment; The Connaught Rangers; The Prince of Wales' Leinster Regiment; The Royal Munster Fusiliers; The Royal Dublin Fusiliers; The South Irish Horse"
