According to researcher Michelle Gordon from Uppsala University, Sweden, Francis Gregson was a correspondent for the St. James’s Gazette. His album of 232 silver gelatin print photographs, entitled "'Khartoum 1898"', documents the Anglo-Egyptian campaign against the Sudanese Mahdist State as a visual narrative. This narrative started in Alexandria, Egypt, and followed the troops southwards to Omdurman, where the decisive battle took place on 2 September 1898.
