Echo Lyrics Meaning
The SS Laurentic sank on 25 January 1917 after striking two mines laid by the German submarine SM U-80. Of the 3,211 gold bars on board, Royal Navy divers recovered 3,186 by 1924. Three more were found in the 1930s, leaving 22 unaccounted for. The wreck is protected under Irish law. #IrishHistory #SSLaurentic #Donegal #Shipwreck #LostGold
