July 17, 1944 Two ammunition ships explode at Port Chicago, Calif., killing 322, including 202 African-Americans assigned by the Navy to handle explosives. It was the worst home-front disaster of World War II. The resulting refusal of 258 African-Americans to return to the dangerous work underpinned the trial and conviction of 50 of the men in what is called the Port Chicago Mutiny.~ Union Communication Services
