Charles Foulkes (British Army officer)

Major-General Charles Howard Foulkes, CB, CMG, DSO (1 February 1875 – 6 May 1969) was a Royal Engineers officer in the British Army and also a British international field hockey player who competed in the 1908 Summer Olympics in the bronze medal-winning team. He saw service in World War I and, following the first German use of gas on 22 April 1915 at the Second Battle of Ypres, became Britain's chief advisor on gas warfare. He also advised on the use of gas to suppress the uprisings in Afghanistan (1919) and Waziristan (1920), but gas was never actually deployed in these conflicts.
