Port Chicago Disaster

Concord, California
July 17, 1944

During World War II, African American Sailors served in separate (segregated) units. Most of them worked as cooks, loaders, or stewards. At Port Chicago, they worked under unsafe conditions to load ships with weapons and ammunition. One night, the ammunition exploded killing 320 men.

Mutiny at Port Chicago?

Three weeks after the explosion that killed 320 men at Port Chicago in 1944, it was time to resume loading ships with weapons. African American sailors at nearby Mare Island Naval Yard marched toward their duty station but stopped because they felt that the unsafe conditions hadn't been resolved. Fifty sailors were charged with mutiny.

Lessons from the 1944 Port Chicago Trial

The 50 Black sailors accused of mutiny after the Port Chicago explosion were found guilty. After their "court martial" (trial) the Navy began to provide training for all sailors who moved weapons. In 1946, the Navy stopped grouping sailors by race. This event inspired many people who would organize for civil rights in the following decades.

Thurgood Marshall

Thurgood Marshall was a lawyer who believed that all people should be treated equally, regardless of race. Marshall went to the court martial of the 50 Black sailors charged with mutiny at Port Chicago. He asked "Why are only Black sailors doing this dangerous work?" Later he became the first African American justice of the United States Supreme Court.
