Charles Chaillé-Long (1842–1917) was an American from the state of Maryland who enlisted as a private in the Union Army in the Civil War, fought in the Battle of Gettysburg, and rose to the rank of captain. In 1870 he was one of the approximately 50 former Union and Confederate officers recruited to assist the khedive of Egypt in developing a national army. He became chief of staff to General Charles (“Chinese”) Gordon when Gordon was governor of Equatoria Province in Sudan. In that capacity, in April 1874 Chaillé-Long set out on a diplomatic mission to Mutesa, king of the Baganda tribe, thereby becoming the first American to visit Uganda. He went on to explore Lake Victoria and the Nile. Chaillé-Long returned to Khartoum in October 1875. He departed again in December to lead an expedition to the Makraka Niam-Niam (as he called Azande country), and the Nile-Congo watershed. Central Africa: Naked Truths of Naked People is Chaillé-Long’s account of his travels in Sudan and Uganda. The book is written in flamboyant prose and is full of self-praise for the author’s accomplishments. Chaillé-Long later returned to the United States, graduated from Columbia Law School in 1880, and practiced law in Alexandria, Egypt for two years. He became, in 1887–89, the U.S. consul general in Korea. He wrote numerous articles and travel books in both English and French.
