a nuclear explosion?

a story too important to ignore

Introduction – The Unexplained Explosion

July 17, 2019 will mark the 75th anniversary of the Port Chicago explosion, the worst disaster to take place on American soil during World War II.  


This coming July will mark the 75th anniversary of the greatest World War II disaster on American soil. At least three civilians were among the estimated 320 people killed  in the massive explosion that rocked the Port Chicago Naval Ammunition Depot near San Francisco, California on July 17, 1944.

The pier was destroyed in the blast, as were the two ships docked there. The E.A. Bryan, loaded with 4,600 tons of ammunition, was obliterated. The S.S. Quinault Victory was a new ship slated for her maiden voyage; her broken remains lay half-buried in the Suisun Bay.

Only 51 bodies were found. The 270 military personnel listed as missing or unidentified included 202 Black seamen and 3 White officers as well as other military personnel from the U.S. Navy Armed Guard, Coast Guard and Maritime Service.

An additional 390 people suffered serious injuries. A mile away, in the small town of Port Chicago, every building was damaged. Damages were reported in San Francisco, nearly 50 miles north, and the effects of the blast were felt as far away as Nevada, 430 miles to the south.

The military base where the explosion took place opened in 1942 as the Naval Ammunition Depot – Port Chicago.The site, which lies 35 miles north of San Francisco, is now known as the Concord Naval Weapons Station(CNWS). The military base gained national attention in June 2018 when ABC News reported that the U.S. Navy was considering plans to convert the site into a detention center for up to 47,000 undocumented immigrants. After an outpouring of public protest, U.S. Government officials announced that plans to convert the base into a “migrant relocation camp” were not moving forward.

This was not the first controversy involving CNWS.  Shortly after opening in 1942 it became the main depot supplying ammunition to the Pacific Fleet. Ever since opening in December of that year the area has had a checkered history

The Navy Razes the Town

Twenty-four years later the U.S. Navy bought the small town, citing unspecified hazards. They evicted the residents, who protested to no avail, and razed the entire area.

The explosion of ’44 caused damage to buildings in the nearby town of Port Chicago. 

Activists Protest

In 1987 Brian Willson, a ‎Viet Nam veteran, lost his leg  when a train failed to stop as he and other activists began a hunger strike on the railroad tracks “to block arms shipments headed for the Contras and President Ronald Reagan’s so-called “secret war” in Nicaragua.”

According to some reports, one notable resident, San Francisco 49er Dan Colchico, armed himself with a Winchester rifle. When two deputy marshals showed up to evict his family, Cochico chased them off his land.

Superfund Site

In 1985 the site was identified as one of 245 nuclear arsenals in the United States. Nearly a decade later later the U.S. Health Department found that past activities at the site “generated and released hazardous wastes into the environment.” CNWS was listed as a Environmental Protection Agency (EPA) Superfund site in 1994.

The GoMentum Station,  a proving ground for ‎self-driving cars, was established on the site in 2004.

The Port Chicago Explosion

The most historic event at the site occurred on July 17, 1944 when a massive explosion rocked the pier. Two ships were destroyed in the blast. The E.A. Bryan, loaded with about 4,600 tons of ammunition, was utterly obliterated. The S.S. Quinault Victory, a new ship slated for her maiden voyage, was broken in half. The tip of her remains stood upright in the Suisun Bay like two dancing whales.

An estimated 320 people were killed in the blast, but only 51 bodies were found. Among those unidentified or missing were 3 White officers and 269 other military personnel, including 202 African-American recruits.

It was the greatest homefront disaster of World War II. The unexplained blast made international news; yet today few people know about the Port Chicago disaster and the mass courts martial that followed.

Unknown Cause

The Commandant of the Twelfth Naval District appointed a Court of Inquiry (COI) to investigate the facts surrounding the disaster. In their Opinion they stated

“…That the evidence does not show that there was any intent, fault, negligence, or inefficiency of any person or person in the naval services or connected therewith, or any other person, which caused the explosions.” [emphasis added]

Still, in many accounts the unexplained blast is blamed on the untrained Black seamen who, many say, may have been careless or mishandled the ammunition. (It was rumored that inexperienced White officers made the young stevedores race to load the ships bound for the war in the South Pacific.)

Nuclear Bomb Theory

Some people think the blast was the first full-scale nuclear explosion . Some believe it was accidental. An adamant minority are convinced it was an experiment conducted by the Manhattan Project, the secret program to develop the first atomic bomb.

I bet I know what you’re thinking:

“No way.

“Ludicrous. Never happened. Couldn’t have.”

“The first atomic bomb test didn’t take place until a year later, on July 16, 1945.”

“It’s just another conspiracy theory.”

“Prove it.”

Okay, maybe the nuclear bomb theory is wrong. After all, the Court decreed that we would never know the cause since all possible eyewitness died in the explosion.

On the other hand, eyewitness testimony is not always reliable. In ”Why Science Tells Us Not to Rely on Eyewitness Accounts.”, an article in the January 1, 2010 issue of Scientific American, writers Hal Arkowitz and Scott O. Lilienfeld point out that “Eyewitness testimony is fickle and, all too often, shockingly inaccurate.” They cite statistics from the Innocence Project where

“researchers have reported that 73 percent of the 239 convictions overturned through DNA testing were based on eyewitness testimony. One third of these overturned cases rested on the testimony of two or more mistaken eyewitnesses.“

Even if there had been eyewitnesses to the Port Chicago explosion it is unlikely that their testimony would have been very accurate. Besides, no one person would have had the whole picture. Instead of leading to a clear conclusion, the contradictory testimony of eyewitnesses could have caused more confusion.

Fortunately there are better ways to investigate the cold case. For historians the most important evidence comes from primary sources. These include documents, historic objects and other information created at the time period under study.

Several documents provide information about the conditions at the Port Chicago Naval Ammunition Depot and the activities that occured there before and after the historic explosion. Take, for example, this list recorded in the War Diary for July 1944:

Among the officers and technicians not assigned to duty in the Twelfth Naval District who visited Port Chicago immediately after the disaster were:

Capt. J. C. Byrnes, Jr., of the Bureau of Ordnance

Capt. Radfor Moses, of the Bureau of Ordnance

Comdr. M. G. Johnson, Bureau of Ordnance

Comdr. J. H. Sides, Bureau of Ordnance

Lt. Comdr. Dexter Bullard, Bureau of Ordnance

Capt. W. S. Parsons, from the Office of Chief of Naval Operations

Col. Crosby Field, of the Joint Army-Navy Ammunition Storage Board

Lt. Col. Ruel Stratton, of the Joint Army-Navy Ammunition Storage Board

Professor John F. Burchard, Chairman DOLOC Committee, Office of Scientific Research and Development [OSRD]

D. Max Beard, of the Naval Ordnance Laboratory [NOL], Navy Yard, Washington, D. C

E. Moss Brown, [NOL], Navy Yard, Washington, D. C.

One of these men, Captain William S. Parsons, will be a major “person of interest” in future posts of The Port Chicago Witness. 

CAPT. William S. Parsons, USN (l) with physicist Philip Abelson

Parsons is best known as the Navy captain who armed the atomic bomb on the Enola Gay as that B-29 bomber made its fateful flight to Hiroshima in the early morning of August 6, 1945. For some reason very few history books identify him in his most important role: head of the Manhattan Project’s Ordnance Division at Los Alamos, New Mexico, where the atom bomb was created.

Why did Captain Parsons visit Port Chicago in the aftermath of the explosion? He was interested, he said, in the effects — not the cause — of the explosion. The preliminary memorandum he wrote to Rear Admiral William Purnell provides significant details about the destructive impact of the blast.

It would take a little more research to find out whether the COI ever got to see the preliminary memo (or any of those that followed), but there is no doubt they were aware of the document: one of the three people who served on the Court was Captain Jack Crenshaw, Parson’s brother-in-law.

Parsons did not indicate in the memo where he was just before he arrived in Port Chicago on July 20th or how long he stayed at Port Chicago. It is a reasonable assumption that he and Crenshaw, long-time friends, dined together, but without further evidence we can only guess what they talked about.

I wondered:

  • Why was Parsons’ brother-in-law involved in the investigation?

What do you think?

Was there a nuclear test at Port Chicago?


These are they who made the ultimate sacrifice

“I am gratified to learn that, as was to be expected, Negro personnel attached to the Naval Magazine Port Chicago performed bravely and efficiently in the emergency at that station last night. These men, in the months they served at that command, did excellent work in an important segment of the District’s overseas combat supply system. As real Navy men, they simply carried on in the crisis… in accordance with our Service’s highest traditions.”
