Tensions between servicemen and civilians were on the rise as thousands of military men on leave poured into Los Angeles, seeing the city as a playground for booze, women, and fights. While many civilians tolerated them because of the war effort, others did not. Particularly in the segregated, ethnic enclaves of Los Angeles, unruly servicemen met stiff opposition from young men and women who refused to defer to the presumed prerogatives of white privilege. While white military men and civilian youth of all colors clashed in the streets, confrontations occurred most frequently between white servicemen and Mexican Americans, because they were the largest minority group in Los Angeles.
Drunken military men on their way back to base after a night of carousing were often "rolled" by civilian minority youth hoping to teach them proper respect. With equal animosity the sailors would often insult Mexican Americans as they traveled through their neighborhood. In the barrios, rumors spread about sailors searching out Mexican American girls. On the military bases, stories circulated about the violent reprisals suffered by sailors who dared to date Mexican American females. Sailors complained bitterly about their wives or girlfriends being subjected to the sexual taunts of young Mexican Americans. The tension continued to escalate until a street fight between sailors and Mexican American boys sparked more than a week of fighting in June of 1943 known as the Zoot Suit Riots.
On the evening of Monday, May 30, 1943 about a dozen sailors and soldiers were walking on a downtown street. After spotting a group of young Mexican American women on the opposite side of the street, the sailors and soldiers changed direction and headed their way. Between the military men and the young women stood a group of young men in zoot suits. As the two groups passed each other, Sailor Joe Dacy Coleman, fearing he was about to be attacked, grabbed the arm of one of the zoot-suited young men. Coleman's move proved to be a big mistake. Coleman was almost immediately struck on the head from behind and fell to the ground, unconscious. Other young civilians pounced on the sailors with rocks, bottles and fists. After the ferocious attack, the sailors managed to escape and carry Coleman to the safety of the Naval Armory. "The fracas lasted little more than a few minutes, but the shock reverberated for days," wrote historian Eduardo Pagán, "The details of the fight grew larger and more distorted in each re-telling of the story." It wasn't long before sailors organized a retaliatory strike against zoot-suiters.
About fifty sailors left the Armory on the night of Thursday, June 3, armed with makeshift weapons. The attack on Seaman Coleman was still fresh in their minds and rumors of new attacks were swirling through the base. Their first stop was the nearby neighborhood of Alpine Street -- scene of many previous confrontations. Unable to find any zoot-suiters at Alpine, they proceeded toward downtown and stopped at the Carmen Theater. After turning on the house lights, the sailors roamed the aisles looking for zoot-suiters. The first victims of the zoot suit riots -- 12 and 13-year-old boys -- were guilty of little more than being in the wrong place at the wrong time. Ignoring the protests of the patrons, the sailors tore the suits off their bodies and beat and clubbed the boys. The remains of their suits were then set ablaze.
As the mob of sailors moved on, reports began to reach the Armory's watch commander. Executive Officer Lieutenant Charles Bacon was sent to investigate. After failing to find any evidence of wrongdoing at numerous spots, Bacon came upon the Shore Patrol marching a group of sixty men to the Central Police Station, where they were to be placed in jail. Bacon assumed control of the situation and saw to it that no charges were recorded by the Shore Patrol.
As the second night of rioting began, Mexican American young men drove back and forth in front of the Armory, hurling epithets at the guards. Later that night sailors once again headed out in search of trouble. When the sailors could not find enough zoot-suiters, they decided to take the fight into the Mexican American neighborhoods of East Los Angeles and Boyle Heights. It was a new twist on the violence: instead of focusing their attacks in areas where sailors and civilian youth had clashed, the sailors moved into the Mexican American neighborhoods. Thus their retaliatory strike became an assault on the Mexican American community itself. The sailors cruised the barrio, storming into bars, cafes and theaters.
Los Angeles police were unwilling to step in and protect civilians. One policeman was quoted after the riots as saying: "You can say that the cops had a 'hands-off' policy during the riots. Well, we represented public opinion. Many of us were in the First World War, and we're not going to pick on kids in the service."
The violence continued during subsequent nights, enveloping even those who had no connection to jazz or the zoot suit. When a group of Mexican musicians exited the Aztec Recording Company after a recording session, they too were attacked. The musicians were all adults, and none of them wore a zoot suit. Military commander Clarence Flogg reported that there were "hundreds of servicemen prowling downtown Los Angeles mostly on foot -- disorderly -- apparently on the prowl for Mexicans." The Navy reported that "Groups vary in size from 10 - 150 men and scatter immediately when Shore Patrol approaches. Men found carrying hammock cues [clubs], belts, knives and tire irons..."
Although groups of armed servicemen roamed the streets attacking civilians, the military seemed more concerned with regaining control over their men than with the violence they were committing. Leery of the negative press that would result from mass arrests, Admiral Bagley, the commanding officer, appealed to his sailors' "common sense."
Mexican American kids organized and fought back. Rudy Leyvas and his friends set traps for the sailors and civilians who were pursuing them, using decoys to lure their attackers in to a trap. "And they let out a cry: There they are! There they are! And they came in. As they came in, once they got all the way in, we all came out … I, myself, had a bat. And I used it."
The worst violence occurred on Monday, June 7. One Los Angeles paper printed a guide on how to "de-zoot" a zoot suiter: "Grab a zooter. Take off his pants and frock coat and tear them up or burn them." That night a crowd of 5,000 civilians gathered downtown. By this time the mob was no longer made up of only sailors from the Armory. Soldiers, Marines, and sailors from other installations as far away as Las Vegas eagerly joined in the assaults. Part of the mob headed south for the predominately African American section of Watts and another group headed east for Mexican American East Los Angeles.
Al Waxman, editor of the Eastside Journal, a small Jewish newspaper, witnessed the chaos. He describes a "mass of humanity locked in violent struggle, arms swinging, legs kicking, shrieking with anger." The police were arresting dozens of young Mexican Americans. "Why am I being arrested?" one of them asked. The response was a savage clubbing with a nightstick. Although the boy fell to the sidewalk unconscious, he was kicked in the face by police.
By Tuesday morning the rioting was finally under a measure of control. Senior military officials declared Los Angeles off limits to all sailors, soldiers and Marines. The Shore Patrol gave orders to arrest disorderly personnel. The following day the city council adopted a resolution that banned the wearing of zoot suits on Los Angeles streets, punishable by a thirty-day jail term.
As the riots subsided, the governor ordered the creation of a citizens' committee. Its charge was to investigate and determine the cause of the riots. In 1943 the committee issued its report; it determined racism to be a central cause of the riots. At the same time, Mayor Fletcher Bowron came to his own conclusion. The riots, he said, were caused by juvenile delinquents and by white Southerners. Racial prejudice was not a factor.
