to Africa to promote segregation, sparking a national debate. While in the Senate, Butler served on the Senate Foreign Relations, Territories, Military Affairs, Naval Affairs, Interstate Commerce, Civil Service and Retrenchment committees. Butler practiced law in Washington, D.C., until 1898, when he was appointed major general of U.S. Volunteers during the Spanish–American War. He was one of a handful of former Confederate officers (along with Fitzhugh Lee, Thomas L. Rosser, and Joseph Wheeler) to serve in the U.S. Army during that war. After the American victory that year, he supervised the evacuation of Spanish troops from Cuba. He was honorably discharged from the U.S. Army on April 15, 1899. In 1899 General Butler joined the Pennsylvania Commandery of the Military Order of Foreign Wars. In 1903, Butler was elected vice president of the Southern Historical Society. In 1904 he relocated to Mexico, where he served as president of a mining company. Having been a widower for years since his wife Maria died, in 1906 he married Nannie Whitman. They returned to Washington, DC. Butler died there in 1909 while semi-retired. His body was returned to Edgefield, South Carolina, where he was buried in the city's Willow Brook Cemetery. The Matthew C. Butler Camp #12 of the South Carolina Society of the Military Order of the Stars and Bars is named in his honor.
