During the Easter Rising, the barracks was occupied by the 10th Battalion of the Northamptonshire Regiment under the command of Major Phibbs. At the end of World War I, the regiment still occupied the barracks. On two occasions during the War of Independence, the regiment carried out reprisals in the town – one for the shooting of District Inspector Wilson who was shot in Patrick Street after which they completely burned the Town Hall and on the second occasion wrecking most of the houses in the town to avenge a successful ambush. During those years the troops were used against the Irish Republican Army in County Tipperary, together with the Black and Tans and the Auxiliaries (stationed in Sir John Cardon’s residence, later burned down in the civil war).
