The Russo-Japanese War, which began in 1904, marked a turning point between a "golden age" of war correspondence and a new era of censorship and military control of journalists. Novelist Jack London, one of the most popular writers in the world in 1904, enthusiastically accepted an offer from William Randolph Hearst to report on the war for the San Francisco Examiner, saying he went to Japan "expecting to get thrills." At first, he got them by sneaking into Korea and avoiding Japanese bureaucracy. After a few weeks, however, he was subjected to strict censorship and prevented from witnessing battles as often and as closely as he would have liked. The unexpected control of the news was a shock, leaving London bitter and frustrated, and predicting fundamental changes in the future role of war correspondents. London considered his work in Asia a failure, but there was little he could have done differently. This paper traces London's coverage of the war and his change in attitudes about combat journalism. Little scholarly work has been done on London's war correspondence, and none, as far as the author can determine, uses London's private war notebook and the regulations issued to foreign journalists by the Japanese First Army. Both of these, along with London's letters and dispatches to the Examiner, form the foundation of this paper's research.
