Under the
Anglo-Irish Treaty (which marked the end of the
Irish War of Independence), the complex was handed over to troops of the Irish Free State on March 1, 1922. Due to escalating tensions between Free State and Republican troops, the barracks were handed over to Republican forces on March 5, as part of a truce agreement agreed between
Liam Lynch, Commandant of the Republican Forces, and Commandant General Michael Brennan of the Free State Army. Towards the end of March the barracks was commanded by
Connie (Mackey) McNamara. At the height of the Irish Civil War, the barracks was besieged by Free State troops under the command of Commandant General Michael Brennan between the July 15–20, 1922. In the late evening of July 20, Captain McNamara surrendered control of the barracks to the Free State forces. The bullet holes from the conflict are still visible in the neighbouring houses. and troops there were used in the Cork and Kerry landings in August 1922. The barracks housed forces of the Free State Army through the remainder of the Irish Civil War and for 13 years was home to units of the Southern Command of the
Irish Defence Forces. The Barracks was then handed over to the Limerick Corporation in 1935. ==1930s to present==
