Backstory and Context
Naval personnel worked quickly to contain the fires and to prevent other explosions. Injuries were treated, those seriously injured were hospitalized, and uninjured servicemen were evacuated to nearby stations. After the fires had been contained, there remained the gruesome task of cleaning up, including picking up body parts and corpses that littered the bay and port.
Of the 320 dead, only 51 could be identified by their remains. Most of the uninjured sailors volunteered to help clean up and rebuild the base. Divisions Two, Four and Eight—reinforced with replacement sailors fresh from training at NSGL—were taken to Mare Island Navy Yard and ordered to man the ammunition depot and loading piers. On August 8, 1944, the USS Sangay docked to be loaded with naval mines and other munitions. 328 survivors of the Port Chicago disaster were ordered to resume the dangerous task of ammunition loading without any review or changes to the loading procedure. Until changes were made to improve safety, each of the 328 men refused the order and asked that there be a review of the officers and conditions that led to the accident.
On August 11, 1944, the Black servicemen were marched to a nearby sports field and lectured by Admiral Wright. Rather than acknowledge the legitimacy of their concerns, Wright lectured them about the need for ammunition in the South Pacific. If they did not immediately start loading the munitions, they would be considered guilty of mutinous conduct, the Admiral explained, a charge that could include the death penalty in times of war. Wright, who had seen nearly 400 of his men killed in 1942 in the Battle of Tassafaronga, said that although loading ammunition was risky, death by firing squad was the greater hazard.
The men continued to press their demands for a review of their officers and safer conditions, including more time for breaks to reduce the physical demand of loading heavy boxes and likely contributed to the accident. The majority of the men were court marshaled and given a dishonorable discharge. The 50 remaining men—soon to be known as the "Port Chicago 50"—were formally charged of mutiny in early September 1944. These men were accused of disobeying orders and making a mutiny "with a deliberate purpose and intent to override superior military authority." If convicted, the men could be punished by death since the United States was at war.
On October 24, 1944, Admiral Osterhaus and the other six members of the court deliberated for 80 minutes and found all 50 defendants guilty of mutiny. Each man was reduced in rank to Seaman Apprentice and sentenced to fifteen years of hard labor to be followed by dishonorable discharge. Outside of the courtroom, Thurgood Masrall connected the tragic incident and its aftermath to the discrimination that African Americans faced within a segregated military. “This is not 50 men on trial for mutiny,” Marshall explained, "this is the Navy on trial for its whole vicious policy toward Negroes.”
The Port Chicago 50 were released from their labor prison camp conditions at the end of the war. Meanwhile, the tragic incident and aftermath drew attention in the press and led to some reforms, including greater safety measures and assigning both white and Black units to the task of loading munitions.
