My grandfather worked for the Asiatic Steam Navigation Company based in Calcutta from about 1904 until at least 1913. He did not return to Britain until the end of World War One, though his family returned in 1914. So far I have been unable to find out what he was doing during the war years and what role the A.S.N.Company played in the Great War. Has anyone any bright ideas where I can find this information. Any help much appreciated.
