The Irish Army disagreed, fearing a German invasion would overrun it quickly, so both finally agreed on a site in the south of County Tipperary, in the valley of the river Suir, east of the Galtee Mountains. This also suited the Irish Army as they had built a secret command headquarters near a convent school seven miles away to be used in case of invasion. The name "Rathduff" was chosen as a cover because such a name is to be found all over Munster. Both sites were completely out of bounds for all normal military operations.
