William Sidney Hatfield (May 15, 1891 or 1893 – August 1, 1921), was a West Virginia law enforcement officer noted for his involvement in bitter labor disputes, on the side of labor, during the Coal Wars of the early 20th century. Hatfield was police chief of Matewan, West Virginia during the Battle of Matewan, a shootout that followed a series of evictions carried out by detectives from the Baldwin–Felts Detective Agency. He was indicted on murder charges stemming from the conflict and was shot on the courthouse steps by Baldwin-Felts detectives. History Hatfield was born in Blackberry, Pike County, Kentucky, the tenth of twelve children (of whom nine survived infancy) of Jacob Hatfield (c. 1843/45 – 1923), a tenant farmer, and his wife Rebecca Crabtree (b. circa 1856). His grandfather, Jeremiah Hatfield, was a half-brother to Valentine Hatfield (1789–1867), grandfather of William Anderson "Devil Anse" Hatfield, leader of the Hatfield family involved in the famous Hatfield–McCoy feud (see Hatfield family tree). According to the 1900 Census, two older brothers, Orison and Hereford, an older sister Chloe, and a younger sister and brother, Martha Alice and Freeland, were then still living at home with him and their parents. His eldest sister Vandalia or Vandella was already married by this time, and an older brother, Melvin, had left home. As a child, Hatfield worked on his father's farm. He became a miner in his teens, and then worked as a blacksmith for several years. He received his nickname, "Smilin' Sid", because of the gold caps on several of his upper teeth. He seems to have had a reputation for hard living and fighting, and his appointment in 1919 to the post of Police Chief of Matewan, by the mayor, Cabell Cornelis Testerman (1882–1920), surprised some of the more "respectable" townsfolk. However, he was a staunch supporter of the United Mine Workers of America, as was Testerman: together, they were instrumental in leading the mining community's resistance to the Baldwin–Felts operatives. Operatives offered both men substantial bribes to allow them to station machine guns in the town. Hatfield and Testerman refused. The Battle of Matewan was precipitated by the Baldwin–Felts agents' attempts to evict the families of unionized miners. On June 2, 1920, in Huntington, he married Jessie Lee Maynard (1894–1976), the widowed second wife of Testerman, who had been mortally wounded in the battle.
