 In 1916, the British had intercepted German communications coming from Washington and suspected that there was going to be an attempt to land arms shipments on Irish shores, although they were not aware of the precise location.The arms ship SS Libau, masqueraded as a merchant ship, under Captain Karl Spindler, was apprehended by HMS Bluebell on the late afternoon of Good Friday.In the early hours of 21 April 1916, three days before the Easter Rising began, the German submarine put Casement ashore at Banna Strand in Tralee Bay, County Kerry.
