On March 30, 1908, Green Cottenham was arrested by the sheriff of Shelby County, Alabama, and charged with “vagrancy.”... Cottenham’s offense was blackness.... [After a brief trial] Cottenham... was sold. Under a standing arrangement between the county and a vast subsidiary of the industrial titan of the North — U.S. Steel Corporation — the sheriff turned the young man over to the company for the duration of his sentence.... he was chained inside a long wooden barrack at night and required to spend nearly every waking hour digging and loading coal. His required daily “task” was to remove eight tons of coal from the mine. Cottenham was subject to the whip for failure to dig the requisite amount, at risk of physical torture for disobedience, and vulnerable to the sexual predations of other miners.... Forty-five years after President Abraham Lincoln’s Emancipation Proclamation freeing American slaves, Green Cottenham and more than a thousand other black men toiled under the lash at Slope 12.
