 While white supervisors were given time off, black sailors were ordered to go back to work despite unsafe conditions. When some of the men refused, they were all court-martialed and given bad conduct discharges. After reviewing the case, the Navy fully exonerated all 256 defendants. The case is part of a recent effort by the Navy to take another look at decades-old cases, especially where race may have played a role in the conviction. For NPR News, I'm Steve Walsh.
