During World War II, munitions were being loaded aboard the cargo vessel SS E. A. Bryan at Port Chicago Naval Magazine for shipment to the Pacific Theater. Unsafe loading practices and racial inequities—Black enlisted men were assigned the dangerous work under white officers—created hazardous conditions that went unaddressed.
On July 17, 1944, the munitions aboard the SS E. A. Bryan detonated at the Port Chicago Naval Magazine in California, killing 320 sailors and civilians and injuring at least 390 others. A month later, hundreds of servicemen refused to continue loading munitions under the same conditions, an act prosecuted as the Port Chicago Mutiny; fifty men were convicted of mutiny and sentenced to 15 years of hard labor.
The disaster and subsequent mutiny became a prominent civil rights cause, drawing national attention to racial discrimination in the U.S. military. Public pressure led the Navy to reconvene courts-martial reviews and ultimately contributed to the desegregation of Navy forces beginning in February 1946. In 2024, the Navy posthumously exonerated all 256 men convicted in the courts-martial proceedings.
