After sundown on July 17, something happened at a small port town 40 miles northeast of San Francisco that has never been fully explained…

The 7,500-ton Liberty ship SS E.A. Bryan had been loading there for days; 98 black enlisted men were on board, continuing to stack ammunition into the hold. Also on board were 31 Merchant Marine crewmen and 13 armed guards.

At 10:19 PM, a mighty blast erupted in the port area when one of the ships blew up, followed five seconds later by the other. The night sky was alight in a gigantic fireball as structures close to the blast vanished in a blinding flash. The Bryan was virtually vaporized.

Hundreds of civilians in the area were injured, including six at the Benicia Arsenal, located to the west across Suisun Bay, where $150,000 in damage was done to arsenal buildings. Within the port, buildings were leveled, vehicles and railroad cars were tossed about like toys, and fires were burning everywhere.

When a massive explosion shook Port Chicago, a key naval depot near San Francisco, the shockwaves set off the largest mutiny trial in U.S. history.

As you can read inside this season’s WWII Quarterly magazine, the explosion and its physical, social and legal aftermath clearly illustrated the cost of racial discrimination during this time of war. When President Harry Truman called for the armed forces to be desegregated in 1948, the Navy could honestly say that Port Chicago had been an essential part of the process.
