On 2 September 1898 Kitchener's Anglo-Egyptian army defeated the massed armies of dervishes at the battle of Omdurman. To commemorate the centenary of these events, eleven historians have collaborated to produce a fresh reappraisal of the reconquest and its international repercussions. They examine some of the policies, personalities and issues involved from different perspectives. British political and military policies are reviewed, with studies of the aims and motives of Lord Salisbury, the political problems of Kitchener's command, and the experience of campaigning in the Sudan. There are analyses of the images sent back from the Sudan, the difficulties of reporting the campaign, and the role of unofficial correspondents, with a facsimile reproduction of a dispatch from Winston Churchill. The contributors examine the colonial difficulties that triggered the campaign, the machinations of the Kaiser in trying to bring about a war between Britain and France, the evolution of French attitudes and the resolution of the Fashoda crisis, the well-informed and incisive monitoring of events by Austria-Hungary, and the widespread European view that Omdurman constituted a triumph for 'civilisation'. Finally, the significance of the reconquest is reviewed for its impact upon Sudanese history, particularly for the deeply rooted and enduring legacy of Mahdism.
