Thomas Mayne Reid was an Irish-American novelist who fought in the Mexican–American War (1846–1848). His many works on American life describe colonial policy in the American colonies, the horrors of slave labour and the lives of American Indians. "Captain" Reid wrote adventure novels akin to those by Frederick Marryat and Robert Louis Stevenson, and set mainly in the American West, Mexico, South Africa, the Himalayas, and Jamaica. He was an admirer of Lord Byron.
