 | | Raleigh Edward Colston, son of the ex-wife of one of Napoleon's marshals; Samuel H. Lockett, the engineer who designed the famous defenses that defied Grant's siege of Vicksburg; E. Purdy, a wastrel who was to die in poverty in Cairo in 1881, and the most colorful and controversial of them all, Charles Chaillé-Long. |
 | | Colston's diary, which covers his day-to-day activities during the period he spent in Egypt and The Sudan, is a valuable source, and, although it has been used by several researchers, it has never been published. |
 | | Colston's successor as commander of the expedition was Colonel Henry G. Prout, an ex-Union officer from New York, who continued into the province of Darfur, a formerly independent sultanate which had recently been conquered by a Sudano-Egyptian army. |
