You have clicked on the sea or a portion of Ireland no
longer occupied by British Crown Forces.
British Crown Forces withdrew from the southern 26 counties of Ireland
after a war of independence with the IRA from 1919-1921. Occupation of
six of Ulster's nine counties in north-eastern Ireland has continued since
that time.
The sea is another matter, but then Brittania also claims to rule the
waves.
