 The Irish Republican Army , that controlled much of the southern part of the country during the Irish civil war , issued a 1d , 2d and 6d label , mainly because of a stamp shortage . These were printed in Cork and were to be put on sale in August 1922 , but in the meantime the Irish Free State army landed near Cork and the IRA set fire to their own barracks before they retreated from Cork , destroying most of the labels .
