Kinnecommander of the Port Chicago facility at the time of the explosionhad served in the U.S. Navy from 1915 to 1922 and then returned to the Navy in 1941 to be posted aboard a general cargo ship.

, after which they were considered adequate to the task by the Navy.
Speed contests and safety training
In April 1944, when Captain Kinne assumed command of Port Chicago, the loading officers had been pushing to load the explosive cargoes quickly— per hatch per hour.
The desired level had been set by Captain Nelson Goss, Commander Mare Island Navy Yard, whose jurisdiction included Port Chicago Naval Magazine. Most loading officers considered this goal too high.
On a chalkboard, Kinne tallied each crew's average tonnage per hour.
The junior officers placed bets with each other in support of their own 100-man crews—called "divisions" at Port Chicago—and coaxed their crews to load more than the others. The enlisted men were aware of the bets and knew to slow down to a more reasonable pace whenever a senior officer appeared.
The average rate achieved at Port Chicago in the months leading up to July 1944 was per hatch per hour—commercial stevedores at Mare Island performed only slightly better at per hatch per hour.
There was no system at Port Chicago to ensure officers and men were familiar with safety regulations. Two formal lectures and several informal lectures were given to the enlisted men by commanding officers, but follow-up confirmation of retained knowledge was not performed. Safety regulations were posted at a single location at the pier, but not in the barracks; Kinne did not think the enlisted men would understand such lists. Later the
International Longshore and Warehouse Union (ILWU) responded to word of unsafe practices by offering to bring in experienced men to train the battalion; the Navy leadership declined the offer,
fearing higher costs, slower pace, and possible sabotage from civilian longshoremen. No enlisted man stationed at Port Chicago had received formal training in the handling and loading of explosives into ships. Even the officers did not receive training: Lieutenant Commander Alexander Holman, loading officer at Port Chicago whose duties included officer training, had initiated a search for training materials and samples, but did not organize a training class before disaster struck.

This was the start of the Port Chicago Mutiny. Wright sent an incident report of this mutiny to Washington, D.C., telling his superior officers that the men's "refusal to perform the required work arises from a mass fear arising out of the Port Chicago explosion."

When they heard the orders "Column left" and "Forward March" to march toward the ammunition loading dock, the entire group stopped and would not continue.

The Navy would not countenance such conduct. Seventy of the men changed their minds after their officers made it clear that loading ammunition was their duty. The 258 African-American sailors in the ordnance battalion who continued to refuse to load ammunition were taken under guard to a barge that was used as a temporary

hall for meals. There was also a brief fight in the mess hall, and some prisoners were seen sharpening spoons into makeshift knives. Small sensed a general air of rebelliousness among the prisoners. To counteract the rising tension and offset the disaster he saw coming, Small convened a short meeting that evening aboard the crowded barge and told the prisoners to "knock off the horseplay", stay out of trouble and obey the shore patrol guards (who were Black) and the officers, because the alternative (White Marines as guards) would be worse. He said to the men, "We've got the officers by the ballsthey can do nothing to us if we don't do anything to them. If we stick together, they can't do anything to us."
On August 11, 1944, the 258 men from the prison barge were marched to a nearby sports field and lectured by Admiral Wright, who told them that troops
fighting on Saipan desperately needed the ammunition they were supposed to be loading and that continued refusal to work would be treated as mutinous conduct, which carried the

death by firing squad was the greater hazard.
After the admiral departed, the men were ordered to separate themselves into two groups, one for those willing to obey all orders and one for those not willing. To a man, Division Eight chose to obey all orders. Divisions Two and Four were split by the decisions of their men: Small and 43 others chose to form a group unwilling to obey every order. These 44 were taken back to the brig and the remaining 214 were sent to barracks. On the morning of August 12, six men from Divisions Two and Four who had put themselves in the obey-all-orders group failed to show up for work call; these six were confined to the brig, making 50 prisoners in all. These 50 were identified by the Navy as mutineers.
Throughout August, all 258 sailors were taken to Camp Shoemaker and questioned. Forty-nine of the 50 mutineers were imprisoned in the camp's brig. Joe Small was placed in

. Each was interviewed by officers, sometimes in the presence of an armed guard. Questions focused on identifying "ringleaders" of the work-stoppage and on what was said by whom at the meeting on the prison barge. The men were asked to sign statements summarizing the interrogation, but the officer's version rarely matched the enlisted man's recollection of the interview. Some men, upon seeing that the written statements did not reflect what they had said, refused to sign. Others felt they had no choice but to signthey were being ordered to do so by an officer. Several men refused to give any statement at all. Others spoke freely, thinking that the officer was their
defense counsel.
After the interviews concluded, the 208 men were convicted in summary courts-martial of disobeying orders, Article 4 of the Articles for the Government of the United States Navy (
Rocks and Shoals).) Each was subject to forfeiture of three months' pay. A few of them were held as witnesses for the upcoming mutiny trial. The rest were split into smaller groups and shipped out to the Pacific Theater. Carl Tuggle, one of the 208, said in 1998 that a group of prisoners, including himself, were assigned menial tasks.

. Defending the men were six Navy lawyers, with a leader and one attorney for every 10 men. Lieutenant Gerald E. Veltmann headed the defense.
Veltmann and his team talked to their clients—they discovered that not all of the 50 were experienced ship loaders. Two of the men had never before loaded ammunitionthey were permanently assigned as cooks because of physical conditions making them unsuited to loading. The two cooks had responded "no" when asked if they would load munitions. Another of the 50, who had a broken wrist in a sling, was asked if he would load ammunition, to which he replied that he would not.
More importantly, Veltmann sensed that the men had not conspired to seize command from their superior officers. In a pre-trial brief, Veltmann cited the definition of mutiny from ''Winthrop's Military Law and Precedents'' and asked that the mutiny charges be dismissed as the formal charges against the 50 men failed to allege that they conspired together deliberately to "usurp, subvert or override superior military authority".

, a persistent refusal to work by two or more mensomething that might be called a "strike" among civilianswas sufficient proof of a conspiracy to override superior military authority and was equivalent to mutiny.
Osterhaus agreed with Coakley and refused Veltmann's motion; the trial would proceed as planned.
Prosecution
The trial started on September 14 with each of the 50 men pleading "not guilty". Coakley began his prosecution by calling officers from Port Chicago and Mare Island as witnesses. Commander Joseph R. Tobin of Ryder Street Naval Barracks said that he personally ordered six or seven of the men to load munitions on August 9 but was unable to verify if any others were so ordered. He said that the men he had spoken with were willing to follow any order except to load munitions; that each man expressed fear of another explosion. Tobin verified that the men were not aggressive or disrespectful. Lieutenant Ernest Delucchi, Commander of Division Four at Port Chicago, testified that he personally ordered only four of the 50 defendants to load munitions. Delucchi described overhearing men of Division Eight say to his men, "Don't go to work for the white motherfuckers"
but, under

but was overruled after Coakley explained it was evidence toward conspiracy.
On September 15, Delucchi continued his testimony, saying that some of his men told him they would obey all orders and perform all work except loading ammunition because they were afraid of it. Delucchi confirmed that a cook and a man with a broken wrist were among the 25 men in his division that now sat among the 50 accused. Delucchi added that the cook and a second man were sailors he did not consider "up to par"; the cook in particular was prone to nervous attacks and was seen as a liability at the pier.
Later in the trial, Lieutenant Carleton MorehouseCommander of Division Eight at Port Chicagotook the stand to say that at the first sign of problems on August 9, he assembled his men and read their names off alphabetically, ordering each man to work. Ninety-six of 104 refused and were sent to the prison barge, but all of these men agreed to work after hearing Admiral Wright's speech on August 11; none of Morehouse's men were on trial for mutiny. Morehouse confirmed to Veltmann that some of his men had said they were afraid to handle ammunition. Following Morehouse, Lieutenant James E. Tobin, Commander of Division Two, took the stand. Lieutenant Tobin (no relation to Commander Joseph R. Tobin) related that 87 of his men initially refused to work but that number was reduced to 22 after Admiral Wright talked about the

. Tobin said he put three additional men in the brig the next morning when they, too, refused to work, saying they were afraid. Tobin affirmed that one of the accused men from Division Two was permanently assigned the job of cook because he weighed and was considered too small to safely load ammo.
The next few days of testimony were filled with accounts from African-American enlisted men from Divisions Two, Four, and Eight, who were not standing accused of mutiny. Some of these men had already been convicted of disobeying orders in summary courts-martial. The testimony of the men agreed on several points: that there had been talk among them of a mass work-stoppage leading up to August 9, that some men (none of the accused 50)
had passed around and signed a petition to avoid loading ammunition, and that Joe Small had spoken at the meeting on the prison barge and had urged the men to obey their officers and to conduct themselves in an orderly fashion. Some men said Small's speech included words to the effect of having the officers "by the tail" or "by the ass". Coakley was challenged by Veltmann when he attempted to bring the men's signed statements in as evidence but the court allowed the statements to be used to refresh the men's memories of their answers to interrogation.
Coakley summed up his prosecution case on September 22. His aim was to show the court that a conspiracy had taken placethe mass of accounts from officers and men appeared to support the conclusion that ringleaders and agitators had forced a rebellion against authority. Veltmann pointed out that few of the accused had been ordered to load ammunition, meaning that they could not all be guilty of the charge of disobeying orders. Veltmann stressed that much of the testimony was hearsay and failed to establish a conspiracy or a mutiny. The court, however, seemed to side with Coakley on all points, settling each objection in favor of the prosecution.
Defense
Veltmann scored a victory at the beginning of his defense: he moved and was granted that each officer's testimony could be applied only to the men they had specifically named as having been given the order to work. In principle, this ruling was favorable, but in practice it would benefit the men only if the court had been attentively keeping notes for each accused man. Instead, reporters observed the court to be drowsy at times, with one judge regularly nodding off.
Starting on September 23 and continuing for over three weeks, each of the accused men was brought to the witness stand to testify in his defense. The general trend of the men's responses was that all of them were willing to obey any order except to load ammunition, all were afraid of another explosion, and none had been approached by "ringleaders" persuading them not to workeach had made his own decision. Each man said that he himself had not coerced others to refuse to work. Some of the men related how, following the official interrogation at Camp Shoemaker, they had been under great pressure to sign statements containing things they had not said. Some men said that, at the meeting on the barge, Joe Small had not urged a mutiny and had not uttered any phrase to the effect of having the officers "by the balls". On the witness stand, Small himself denied saying any such thing, though he would admit to it decades later in interviews.
Coakley's
cross-examination
In law, cross-examination is the interrogation of a witness by one's opponent. It is preceded by direct examination (known as examination-in-chief in Law of the Republic of Ireland, Ireland, the Law of the United Kingdom, United Kingdom, Austra ...
s began with an attempt to have the signed statements admitted as evidence. Veltmann objected that each statement was obtained under duress and was not voluntary. Coakley characterized the statements as not being confessions requiring voluntary conditions but merely "admissions" that had no such requirement. Osterhaus ruled that Coakley could not introduce the statements as evidence but that he could ask the defendants questions based on what each man's signed statement contained.
Some of the men who had been named as having been given direct orders to work testified that they had not been given any such order. Seaman Ollie E. Greenwho had accidentally broken his wrist one day prior to the first work-stoppage on August 9said that though he had heard an officer in prior testimony name him as one who had been given a direct order, the officer had only asked him how his wrist was doing, to which he responded "not so good."
At the end of his testimony, Green told the court that he was afraid to load ammunition because of "them officers racing each division to see who put on the most tonnage, and I knowed the way they was handling ammunition it was liable to go off again. If we didn't want to work fast at that time, they wanted to put us in the brig, and when the
exec came down on the docks, they wanted us to slow up."
This was the first that the newspaper reporters had heard of speed and tonnage competition between divisions at Port Chicago, and each reporter filed a story featuring this revelation to be published the next day. Naval authorities quickly issued a statement denying Green's allegation.
Another one of the men gave the surprising testimony that Lieutenant Commander Coakley had threatened to have him shot after he refused to answer some questions during interrogation at Camp Shoemaker. Seaman Alphonso McPherson held fast to his testimony even when faced by Coakley in cross-examination. Coakley denied threatening anyone, exclaiming that such an idea was a personal affront. Veltmann responded that this line of evidence was news to him, too. The next day, Coakley gave the press a statement accusing Veltmann of coaching McPherson.
October 9, 1944, was another in a string of days consisting of accused men testifying on the witness stand. This day, however,

Although Marshall was allowed to observe the trial, as a civilian he was ineligible to take an official role in the men's defense. After hearing five of the men defend themselves, Marshall spoke to the 50 men and then conferred with Veltmann's defense team.
The next day, Marshall held a press conference, charging that Judge Advocate Coakley was handling the case in a prejudicial manner. Marshall said, that from a review of the proceedings and his conversations with the accused, he could see these men being tried only for lesser charges of individual insubordination, not mass mutiny.
The defense continued a few more days with testimony from a Navy

who verified that the immense explosion would generate fear in each man. A Black petty officer under Delucchi testified that he had heard no derogatory remarks or conspiratorial comments and that it had been a surprise to everybody when all of the men suddenly refused to march toward the docks on August 9.
Marshall held another press conference on October 17 to announce that the NAACP was requesting a formal government investigation into the working conditions that had led the men to strike. He called attention to three aspects: the Navy policy that put the great majority of African Americans into segregated shore duty, the unsafe munitions handling practices and lack of training that had led to the catastrophic detonationand the unfair manner in which 50 of 258 men had been singled out as mutineers, when their actions concerning loading ammunition after the explosion were not significantly different from the other 208 men. Marshall pointed to the men of Division One who had refused to load ammunition prior to August 9, but had been shipped out and given other duty, not arrested and court-martialed.
Coakley's rebuttal witnesses consisted of officers who had interrogated the prisoners at Camp Shoemaker. The rebuttal fared poorly, as Veltmann was able to elicit from them: that some of the accused men had not been informed they could refuse to make a statement; that some of the interrogations had taken place with an armed sentry standing guard; that very few of the prisoners' explanations that they had been afraid of another explosion had been included in the statements; and that the officers had emphasized portions of the interrogations that would satisfy Coakley's requirement for evidence of conspiracy. Coakley's last rebuttal witness testified on October 19, and the whole court took October 20 off to allow both sides to prepare closing arguments.
Closing arguments
In his closing argument, Coakley described a chronological sequence of mutinous occurrences, beginning at Camp Shoemaker shortly after the explosion when two and a half companies were mixed together for two weeks. Coakley stated that conspiratorial talk among the men about refusing to work and trying to get out of loading ammunition was the root of their August 9 mass refusal. Coakley described how the mutiny continued in the barge when Joe Small spoke to the men and asked them to stick together. Coakley entered into the record his definition of mutiny: "Collective insubordination, collective disobedience of lawful orders of a superior officer, is mutiny."
He gave his opinion that men who admitted in time of war that they were afraid to load ammunition were of a low moral character and were likely to give false testimony.
Veltmann denied that there was a mutinous conspiracy, saying the men were in a state of shock stemming from the horrific explosion and the subsequent cleanup of human body parts belonging to their former battalion mates. He said the conversations at Camp Shoemaker were simply those of men who were trying to understand what had happened, and that these discussions were not mutinous nor could they provide the groundwork for conspiracy. Veltmann argued that Small's brief four- or five-minute speech to the men on the barge was given in the performance of his duty to maintain order, a duty placed upon him by his superiors. Veltmann restated that the established legal definition of mutiny was a concerted effort to usurp, subvert or override military authority, and that there had been no such action or intent. Refusal to obey an order was not mutiny.

Appeal and release
During the 12 days that he watched the court-martial proceedings, Thurgood Marshall began to formulate an appeal campaign, having noticed that none of the men's grievances had been aired in court. Directly after the court closed the case, Marshall sent a letter to Secretary Forrestal asking why only Blacks were assigned the task of loading munitions, why they had not been trained for that task, why they were forced to compete for speed, why they were not given survivor's leaves, and why they had not been allowed to rise in rank. Forrestal replied weakly,
saying that a predominance of Black men were stationed at Port Chicago so of course they would be working there to load munitions. Forrestal pointed out that there was no discrimination because other naval weapons stations were manned by White crews loading munitions. The Navy Secretary said that the men had not been promoted because their time at Port Chicago had been a "trial period", and that they were not given 30-day leaves because he thought it best for men to get quickly back to duty to prevent them from building up mental and emotional barriers.

. On April 3, 1945, he appeared to present his arguments. Marshall's appeal made the case that no direct order was given to all 50 of the defendants to load munitions and that even if orders had been given to certain individuals, disobeying the orders could not constitute mutiny.

inadmissible. Marshall wrote that "

Admiral Wright stuck by his reduced sentences.
Only two of the 258 men had their convictions set aside during the reviews; one for insufficient evidence against them and one for "mental incompetency" regarding understanding the refusal of orders.

recommended in October that the Navy reduce the sentences to just two years for men with good conduct records and three years for the rest, with credit for time served. Finally, on January 6, 1946, the Navy announced that 47 of the 50 men were being released. These 47 were paroled to active duty aboard Navy vessels in the Pacific Theater, where the men were assigned menial duties associated with post-war base detail. Two of the 50 prisoners remained in the prison's hospital for additional months recuperating from injuries, and one was not released because of a bad conduct record. Those of the 50 who had not committed later offenses were given a
general discharge from the Navy "under honorable conditions". In all, the Navy granted clemency to about 1,700 imprisoned men at this time.
Political and social effect
The Port Chicago disaster highlighted systemic racial inequality in the Navy.
A year before the disaster, in mid-1943, the U.S. Navy had over 100,000 African Americans in service but not one Black officer. In the months following the disaster, the ''

Gordon Koller, Chief Petty Officer at the time of the explosion, was interviewed in 1990. Koller stated that the hundreds of men like him who continued to load ammunition in the face of danger were "the ones who should be recognized".
In 1994, the Navy rejected a request by four California lawmakers to overturn the courts-martial decisions. The Navy found that racial inequities were responsible for the sailors' ammunition-loading assignments but that no prejudice occurred at the courts-martial.
In the 1990s, Freddie Meeks, one of the few still alive among the group of 50, was urged to petition the president for a
pardon
A pardon is a government decision to allow a person to be relieved of some or all of the legal consequences resulting from a criminal conviction. A pardon may be granted before or after conviction for the crime, depending on the laws of the j ...
. Others of the Port Chicago 50 had refused to ask for a pardon, reasoning that a pardon is for guilty people receiving forgiveness; they continued to hold the position that they were not guilty of mutiny. Meeks pushed for a pardon as a way to get the story out, saying "I hope that all of America knows about it... it's something that's been in the closet for so long."
In September 1999, the petition by Meeks was bolstered by 37 members of Congress including
George Miller, the U.S. representative for the district containing the disaster site. The 37 congressmen sent a letter to President

and in December 1999, Clinton pardoned Meeks, who died in June 2003.

This effort did not result in a change of status. In 2006, a local newspaper article highlighted the precarious position of the disused chapel within the grounds of the Concord Naval Weapons Station, a chapel that had been previously dedicated to the memory of those fallen in the explosion.

In 2021, a new park was planned to honor Thurgood Marshall's invaluable work with the 50 African American sailors. The future "Thurgood Marshall Regional Park – Home of the Port Chicago 50" will be formed from a section of the decommissioned Concord Naval Weapons Station, a short distance from Port Chicago, and will join the park system of the East Bay Regional Park District. A visitor center is planned to describe the dangers of weapons cargo loading, and the racism experienced by African-American dock workers. The regional park will partner with the National Park Service to tell the story of the Port Chicago disaster, providing easier access to the public.
Media representations
In 1990, Will Robinson and Ken Swartz produced the documentary ''Port Chicago MutinyA National Tragedy'', about the explosion and trial. They interviewed mutiny convict Joe Small, his defense lawyer Gerald Veltmann, as well as Percy Robinson, a seaman who returned to loading ammunition after the first work-stoppage, and Robert Routh Jr., a seaman who was blinded in the blast.
