The Irish Free State was formed in 1922, and Tom Casement (brother of Roger Casement) tried unsuccessfully to establish a new Irish coast guard. In late 1923 Casement instead became first Inspector of a new Coast Life Saving Service (CLSS). In 1927, before the Irish Naval Service had been formed, the Admiralty discussed the possibility of CLSS participation in minesweeping of the Treaty Ports. During the Emergency declared in the Second World War, the Department of Defence established a separate Coast Watch after the use of the CLSS to keep watch for belligerent ships and aircraft was vetoed by the Department of Industry and Commerce, which ran the CLSS.
