CASEMENT, ROGER DAVID (1864-1916), British con sular agent and rebel, was born at Kingstown, Co. Dublin, on Sept. I, 1864. After serving in the Niger Coast Protectorate he entered the British consular service, and was appointed consul at Lour enco Marques, then at Loanda and then at Boma. He carried out the investigation ordered by the British Government into the conditions under which the rubber trade in the upper Congo was conducted, and his report, published in 1903, led to the official Belgian commission which resulted in the change in the Govern ment of the Congo. In 1910 the British Government commis sioned Casement to investigate certain charges brought against the Anglo-Peruvian Amazon Company, and for this service he was knighted (1911) . He retired from the service in 1912 and returned to Ireland in 1913. Always a strong Irish nationalist he joined the opposition to Redmond and to the participation of Irishmen in the World War. He thought the circumstances of the war might be used to win Irish independence, and with this in view visited the United States and then in Nov. 1914 Berlin. During 1915 he published various anti-British pamphlets and attempted without success to form a brigade, for service against England, of Irish soldiers who were prisoners of war. He found that the Ger mans were not prepared to attempt an expedition to Ireland, and conveyed verbal messages to his friends in Ireland to that effect, hoping thus to prevent an abortive rising, although to no purpose. But when he learned of the proposed rising in Easter week 1916 he sailed (April 12) for Ireland in a German submarine, which was accompanied by a vessel laden with arms and ammunition. The latter was captured by a patrol boat. Casement landed in a collapsible boat, was captured on April 24 and brought to Lon don. Tried for treason before the lord chief justice, he was con victed and sentenced to death on June 29, being deprived of his knighthood on the following day. His appeal against conviction was dismissed on July 18, and on Aug. 3 he was hanged at Pen tonville, London.
