Military

In the spring of 1863, Dwight was part of Grant's invasion of Mississippi at Bruinsburg on the Mississippi River. The invasion preceded the Battle of Port Gibson, and Union troops had taken control of Windsor mansion, where Dwight sketched the only known drawing of the antebellum home.^[3][4]

During the war, Dwight participated in more than thirty engagements, including the siege of Vicksburg (1863), the Atlanta Campaign (1864), and the Savannah Campaign (1864).^[1] Shortly before the war ended, Dwight was commissioned a captain and left the military in 1865.^[1]

Missionary

In 1867, Dwight returned to Istanbul as a missionary for the American Board of Commissioners for Foreign Missions, where he edited publications of the Turkish language.^[2] For 15 years, in the late 1800s, he was the correspondent in Constantinople for the New York Tribune.^[1] During the Armenian Massacres of 1894–1896, Dwight had responsibility for guarding missionary interests in Turkey.^[1]

He was ordained a minister in 1880, and returned to the United States in 1901, after resigning his commission as a missionary. In 1897, Dwight was conferred the honorary degree of LL.D. by Amherst College.^[1] He edited the Report of the Ecumenical Conference on Foreign Missions (1900) and the Encyclopedia of Missions (1904). He was the author of several books:^[2]
