 The Belgian Parliament, pushed by socialist political leader and statesman Emile Vandervelde and other critics of the King's Congolese policy, forced a reluctant Leopold II to set up an independent commission of enquiry.Its findings confirmed Casement's report in every detail.This led to the arrest and punishment of officials who had been responsible for murders during a rubber-collection expedition in 1903 (including one Belgian national who was given a five-year sentence for causing the shooting of at least 122 Congolese natives).
