A notorious incident of the blackbirding trade was the 1871 voyage of the brig ''Carl'', organised by Dr James Patrick Murray, to recruit labourers to work in the plantations of Fiji. Murray had his men reverse their collars and carry black books, to appear as church missionaries. When islanders were enticed to a religious service, Murray and his men would produce guns and force the islanders onto boats. During the voyage Murray shot about 60 islanders. He was never brought to trial for his actions, as he was given immunity in return for giving evidence against his crew members. The captain of the ''Carl'', Joseph Armstrong, was later sentenced to death.
