I asked my Navy veteran husband if he had ever hear of the Port Chicago 50, and he admitted he had never heard of them. During World War II only black sailors were charged with the duty of loading ammunition on ships. When there was a huge explosion that killed over 300 sailors it was not highly publicized because most of the victims were black. When working conditions remained the same, 50 sailors refused to return to work and were charged with mutiny.
This was a fascinating, but frustrating read. A great book about civil rights heroes that are infrequently remembered.
