Trần Văn Đôn

Đôn was born in Bordeaux, France. His father was the son of a wealthy Mekong Delta landowner, which allowed him to travel to France to study medicine. It was during this period that Đôn was born. He returned to France as an adult for his university study. He became a French Army officer when World War II began, later training at École spéciale militaire de Saint-Cyr. Đôn died in 1997.

In 1965, Đôn retired and was elected to the Senate in 1967 after topping the elections. He later served as the defense minister, until 29 April 1975, leaving for the United States one day before the fall of Saigon.

In February 1965, Don was again in view as Phat and Colonel Pham Ngoc Thao made another attempt to overthrow Khanh with the support of Catholic elements aligned with the Dai Viet Quoc Dan Dang and Diemist sympathisers. American intelligence analysts thought Đôn was involved in the coup, but altered their assessment when he stayed in Da Lat instead of heading for the capital. Eight months after the coup was over, Đôn told the American historian George McTurnan Kahin that he had been plotting with Thảo, who had planned for him to become Defense Minister and Chief of Staff of the military, but said the Dai Viet had insisted on installing the Catholic Khiêm. A month earlier, American intelligence analysts thought Thảo was planning to replace Khánh as commander-in-chief with Don.

On May 28, 1964, Khanh put his rivals on trial. The generals were secretly interrogated for five and a half hours, mostly about details of their coup against Diệm, rather than the original charge of promoting neutralism. As all of the officers were involved in the plot against Diệm, this did not reveal any information new to them. The court deliberated for over nine hours, and when it reconvened for the verdict on May 29, Khánh stated, "We ask that once you begin to serve again in the army, you do not take revenge on anybody". The tribunal then "congratulated" the generals, but found that they were of "lax morality" and unqualified to command due to a "lack of a clear political concept". They were chastised for being "inadequately aware of their heavy responsibility" and of letting "their subordinates take advantage of their positions". The four imprisoned generals were allowed to remain in Da Lat under surveillance with their families. However, there were reports that the trial ended in a festive manner akin to a party, as the officers shook hands and made up with one another, with Minh reported to have commended Khanh for his "fairness" before organising a celebratory dinner for the generals. All four generals were barred from commanding troops for a period; Kim was banned for six years, and Đôn 18 months. Offices were prepared for the quartet so that they could participate in "research and planning". Worried that the group of idle officers would plot against him, Khánh made some preliminary arrangements to send them to the United States for military study, but this fell through. When Khánh was himself deposed in 1965, he handed over dossiers proving that the four generals were innocent; the original documents that Khánh claimed proved his accusations of neutralism were neither presented to nor found by anyone.

In September, Khanh survived a coup attempt by Generals Duong Van Duc and Lam Van Phat after the intervention of the 'Young Turks' faction of Nguyen Chanh Thi and Air Force chief Nguyen Cao Ky. To try and counter-act the increasing power of the latter, on November 14, Khánh brought back Don as the deputy chief of staff. However, the Young Turks were cognizant of Khánh's motives, and continued to pressure him to sideline Don and Dinh in an attempt to gain more power for themselves. The Young Turks then decided to try and sideline Don and the Da Lat generals by introducing a policy to forcibly retire officers with more than 25 years of service, as they thought them to be lethargic and ineffective, but most importantly, rivals for power. However, a civilian advisory body named the High National Council, composed mostly of old men, disagreed with this policy, and after refusing to approve it, the Young Turks launched a coup in December 1964 to remove the HNC.

Đôn, then army Chief of Staff, organised discontented officers, and in mid-1963 began meeting with Lucien Conein, a French-born CIA officer in Saigon with whom he culturally related. His closest confidant was his brother-in-law, General Lê Văn Kim, who was also trained in France.

A group of officers, led by Generals Nguyen Khanh, Tran Thien Khiem and Do Mau were unhappy with their posts after the 1963 coup, and began plotting. Incriminating documents were concocted to purportedly show that Generals Minh, Kim and Đôn had been bought by French agents and were on the brink of declaring South Vietnam's neutrality and signing a peace deal to end the war with the North. Some of the documents were leaked to elements of the American presence in Saigon and were brought to the attention of some senior American officials. Khánh told various American officials that Đôn, Kim and General Mai Hữu Xuân, along with Minh, were "pro-French and pro-neutralist" and part of French President Charles de Gaulle's plan to neutralise Vietnam. Khánh claimed that the fact that Đôn had invited two members of the French National Assembly—both from de Gaulle's party—to dinner. According to one source, Kim and Minh were also present, while another said that Kim, Đính and Xuân were there. Khánh alleged at the time that the generals discussed neutralization there, while Đôn and Đính always denied it. Another incident that occurred publicly was a January trip by Đôn and Đính to Thailand's capital Bangkok for a military event was a press conference at which Đôn did not rule out de Gaulle's plan if it applied to both Vietnams equally. Lodge passed a report to Washington on January 20, alleging that Đôn and Đính were potential leaders of a group that might go along with de Gaulle's neutralization plan. He said that Đôn and Kim retained their French citizenship and "had never at any time foresworn the possibility of a neutral solution at what might seem to them the proper time." He said that although he thought their policies against the communists were effective, "none of us had ever discussed what the next step would be after the Government of Vietnam had reached a position of strength. Perhaps they did favor the French neutrality solution at that time."

Đôn became Diệm's chief of staff and presided over a ceremony in Saigon in which the French-style military rank insignias were burnt and replaced with American-inspired new insignias. In the early 1960s, he commanded the I-Corps of the Army of the Republic of Vietnam, which operated in the far north of South Vietnam, in the border region along the demilitarised zone. He led his forces into the mountainous areas of the Central Highlands to flush out pockets of Việt Cộng resistance and to prevent further infiltration from North Vietnam. In all, his command took in five provinces. He often came into dispute with Diệm's brother, Ngô Đình Cẩn, who had his own autonomous private army and secret police and ruled the northern border regions of South Vietnam arbitrarily. Đôn was removed from command of troops and made the Joint Chief of Staff, where he was confined to an office with no troops. His work was mainly travelling to the airport to greet visiting American dignitaries. Diệm feared that the respect that Đôn commanded could make him a possible rival for power, as the army leadership was selected for the purpose of preserving Diệm in power, rather than defeating the communists.

Shortly after 16:00, Diệm telephoned JGS headquarters. Đôn answered and stated "the time has come when the army must respond to the wishes of the people" because Diệm had failed to reform his leadership. The pair had a robust argument and Diệm asked the commanders to visit him at the palace to negotiate and work on a reform plan. The generals, remembering that he bought time for loyalists to come to his aid during the 1960 coup attempt by stalling the coup with talks and a false promise of reform and power-sharing, turned down his suggestion.

He returned to Vietnam and served in the French-backed Vietnamese National Army of the French-backed State of Vietnam, fighting against the Việt Minh in the First Indochina War. Đôn was a colonel in 1955, when he and then fellow colonel Dương Văn Minh helped Ngô Đình Diệm establish himself in control of South Vietnam following the Geneva Accords and partition by helping to subdue the private armies of the Hòa Hảo and Cao Đài religious sects, as well as the Bình Xuyên organized crime syndicate. Both were immediately promoted to the rank of general. With the proclamation of the Republic of Vietnam, military officers were faced with becoming Vietnamese citizens if they wanted to remain in their positions. Đôn became a Vietnamese citizen.

On January 30, Khánh launched a coup, arresting Minh, Dinh, Đôn and Kim, claiming that they were part of a neutralist plot with the Việt Cộng and taken to Đà Lạt. Khánh noted that they had served in the Vietnamese National Army in the early 1950s, under the French colonial administration, although he did as well. The day after coming to power, Khánh further claimed to Lodge that Đôn was in possession of briefing papers from the Americans on plans for the bombing of North Vietnam and said that they were in danger of being handed over to the communists.

Trần Văn Đôn (August 17, 1917 – 1997) was a general in the Army of the Republic of Vietnam, and one of the principal figures in the 1963 South Vietnamese coup d'état which overthrew President Ngô Đình Diệm.
