On April 14, 1980, acting president Choi, now totally subordinate to Chun, promoted him to the rank of lieutenant general and appointed him acting director of the KCIA. These actions prompted student demonstrations throughout the country. Molotov cocktails were hurled at police formations, and the police retaliated with hypervirulent CS tear gas (the same type used by the FBI at Waco in 1993). Everyone knew that Chun had to consolidate his position before the National Assembly convened for the first time since Park’s death on May 20, when the Democratic Republican Party, the façade behind which Park had ruled, was likely to join with the opposition in ending martial law. That would have destroyed any legal basis for Chun’s political ambitions.
In a secret cable dated May 7, 1980, preceding a scheduled meeting with General Chun, Ambassador Gleysteen wrote to his superiors in Washington: “In none of our discussions will we in any way suggest that the USG [U.S. government] opposes ROKG [Republic of Korea government] contingency plans to maintain law and order, if absolutely necessary,
General Chun did not wait long after talking with Gleysteen to complete the coup d’état he had begun the previous December. Late on the night of May 17, 1980, General Chun expanded martial law, closed the universities, dissolved the National Assembly, banned all political activity, and arrested thousands of political leaders.13 Unlike Park, Chun had no following whatsoever outside the army. All Korean cities were tense with fury at his usurpation of power, but only in Kwangju did the situation explode, much in the same way it had in Budapest twenty-four years earlier. What resulted was, in the words of historian Donald Clark, “the most notorious act of political violence in South Korea’s history.” Professor Clark adds that the explicit American endorsement of Chun’s recapture of the city “forever associated the United States with the Kwangju Massacre.”14
On May 18, 1980, a few hundred demonstrators in Kwangju took to the streets to protest the imposition of martial law. They were met by paratroopers of the 7th Brigade of the Korean special forces, known as the “black berets,” who had a well-known reputation for brutality going back to their service on the American side in the Vietnam War. The 7th Brigade also included a battalion of infiltrators and provocateurs, who wore their hair long and dressed to look like students. According to eyewitnesses, the special forces troops set about bayoneting all the young men and women they could find and attacked others with flamethrowers. In a May 19 cable to Washington, Gleysteen wrote, “Rumors reaching Seoul of Kwangju rioting say special forces used fixed bayonets and inflicted many casualties on students. . . . Some in Kwangju are reported to have said that troops are being more ruthless than North Koreans ever were.”
In reaction to these acts of state terrorism, the whole population of Kwangju and sixteen of the twenty-six other municipalities of the South Cholla region rose in rebellion. They drove the paratroopers from the city, which citizens’ councils controlled for the next five days. They appealed to the U.S. embassy to intervene, but General Wickham had already released from his United Nations Command the forces Chun would use to retake the city. Gleysteen later claimed that he was unable to verify the authenticity of the mediation request and therefore decided not to act. “I grant it was the controversial decision, but it was the correct one. Do I regret it? I don’t think so.”
On Wednesday, May 21, martial law command headquarters in Seoul broke its near total censorship of what was going on in Kwangju and reported that 150,000 civilians, about one-fifth of the city’s population, had gone “on a rampage” and that they had seized 3,505 weapons and 46,400 rounds of ammunition from arsenals and had commandeered 4 armored personnel carriers, 89 jeeps, 50 trucks, 40 wreckers, 40 buses, 10 dump trucks, and 8 tear-gas-firing jeeps.15 On the same day, Ambassador Gleysteen wrote to Washington that a “massive insurrection in Kwangju is still out of control and poses an alarming situation for the ROK military.” He said that the Korean military was “concentrating defense on two military installations and a prison containing 2,000 leftists. . . . The December 12 generals obviously feel threatened by the whole affair.”
