In the autumn of 1884, representing the Central News Agency of London, Williams also joined the Gordon Relief Expedition, a British mission to relieve in Major-General Charles George Gordon in Khartoum, Sudan. His was the first dispatch to tell of the loss of Gordon. While in Sudan, he quarrelled with Henry H. S. Pearse of "The Daily News", who later unsuccessfully sued him. After leaving "The Standard" in 1884, he worked with the "Morning Advertiser," but later worked with the "Daily Chronicle" as a war correspondent. He was the only British correspondent to be with the Bulgarian Army under Prince Alexander Joseph of Battenberg during the Serbo-Bulgarian War in November 1885. In the Greco-Turkish War of 1897, he was attached to the Greek forces in Thessaly. His last war reporting was on Herbert Kitchener's Sudanese campaign of 1898. His health did not permit his advance to South Africa, but he was still able to London a diary of the South African War for "The Morning Leader".
