A few years after these events, US undercover agents were watching a Marseilles bar involved in the huge Transatlantic drug-smuggling operation that became notorious as ‘the French Connection’. The surveillance team was startled to identify Conein among those present, gladhanding Corsican gangster friends from his OSS days. Frank Scotton nonetheless argued that beneath Conein’s posturings as buccaneer or buffoon, the big thug could work effectively to fulfil an allotted task, which in October 1963 meant providing the link between the US government, which acquiesced in Diem’s extinction, and the Vietnamese generals who brought this about.
Lodge chafed at the sluggishness of the plotters, who, he wrote crossly, had ‘neither the will nor the organisation … to accomplish anything’. Harkins, having no time for the ambassador, shrugged to Max Taylor, ‘You can’t hurry the East.’ George Ball later argued that the notorious August Harriman/Hilsman telegram was less influential in energising the generals than Kennedy’s TV appearance two weeks later, warning that the US would withdraw aid unless Saigon changed its ways. Many South Vietnamese, both in uniform and out of it, sensed backing for Diem ebbing away. Army lieutenant Nguyen Cong Luan was a passionate anti-communist, who also hated the government: ‘My comrades and I believed that it was necessary to bring new leaders to power so that South Vietnam could deal effectively with the communists and become a place of full freedom and democracy like the United States.’ They had been much excited when South Korea’s dictator Syngman Rhee was forced out of power in 1960. ‘We believed that if our side [in Vietnam] showed enough resolution and strength for a coup attempt, the Americans would have to support us.’
President Kennedy now confused the issue by dispatching McNamara and Taylor on a ten-day ‘fact-minding mission’ to Vietnam, which began on 25 September. They returned to fantasise about ‘great progress’ on the battlefield, while deploring Diem’s intransigence. They had probed in vain for tidings about the supposedly imminent coup. When Gen. Duong Van ‘Big’ Minh, leader of the army plotters, said nothing significant to Taylor during an energetic tennis game at Saigon’s Cercle Sportif, the American decided that the plan must have been aborted. He and McNamara nonetheless concluded that military victory remained attainable, if only the Saigon government could be sorted. Which required removal of the Ngos.
The White House cabled Lodge on 2 October, emphasising that deniability was all: ‘No initiative should now be taken to give any covert encouragement to a coup. There should, however, be an urgent effort … to identify and build contacts with possible alternative leadership as and when this appears.’ Three days later Lodge messaged the president that the coup seemed likely to happen after all. Conein and Minh met for some frank exchanges, conducted in French, at an old colonial bungalow in the Saigon garrison compound. The Vietnamese said that his only non-negotiable demand was an assurance that US aid would continue. He warned Conein that time was of the essence: his own was merely one of several rival conspiracies. That day another Buddhist monk burned himself to death.
Conein’s report caused Lodge to recommend to Washington that he need merely give Minh an assurance that the US ‘will not attempt to thwart’ regime change. Kennedy assented, though warning that Americans must not be actively engaged in the process of a coup. The mood in Saigon was now febrile, with rumours everywhere of an impending threat to Diem. These had their effect in alarming the Vietnamese generals, who once more drew back from the brink. Lodge felt obliged to sack CIA station chief John Richardson, who shared Paul Harkins’ scepticism about dumping Diem.
Then Nhu intensified his campaign of political repression, and publicly heaped obloquy on the Americans for alleged meddling. After the war, senior communists observed that this would have been an ideal moment to provoke an uprising: South Vietnam had become unstable and vulnerable; almost everyone hated the Ngos. COSVN, however, merely sustained its guerrilla campaign, while in Saigon the generals bargained for support from key army units. Lou Conein sought to keep the plotters on course through soothing conversations with Gen. Don at their mutual dental surgery, which became a safe house for meetings.
On 26 October, National Day, Diem visited the hill resort of Dalat. In the prevalent jittery mood, his plane was preceded by an identical but empty decoy C-47, and the welcoming honour guard’s rifles were inspected to ensure that they were unloaded. The president had scheduled a meeting with the US ambassador, and Frank Scotton was tasked to enquire of a Vietnamese contact, privy to the coup planning, whether Lodge could enter the presidential guesthouse without getting caught in a storm of bullets. The USIA man got the necessary nod: the generals were not yet ready. The visit, and Diem’s meeting with the ambassador, took place without incident.
In Washington, divisions persisted. Vice-president Lyndon Johnson exercised little influence, but persistently opposed eviction of the Diems. As a visceral anti-communist, he saw the challenge as being simply to contrive the military defeat of the Vietcong. Never a man for nuances, he liked to pretend to jest ‘Foreigners are not like the folks I am used to,’ though this indeed emphasised an important truth about himself. On 29 October Kennedy convened the NSC to discuss a cable from Harkins, expressing the general’s desire to stick with the Ngos: ‘Rightly or wrongly, we have backed Diem for eight long hard years. To me it seems incongruous to get him down, kick him around and get rid of him.’ This message shook Robert Kennedy, who decided that a coup now looked risky.
National security adviser McGeorge Bundy dispatched another cable to Lodge, reflecting the president’s new doubts. Yet the ambassador had become determined to see the plot through: he never conveyed Washington’s equivocations either to the Vietnamese generals or to Lou Conein. On 1 November the old OSS man arrived by appointment at army headquarters, wearing uniform and carrying a .357 revolver together with $US40,000 in cash, which he deemed the appropriate fashion accessories for an afternoon’s work overthrowing a government. He left his wife and children in their villa guarded by Green Berets, and radioed from his jeep an agreed signal to his superiors that the operation was starting: ‘Nine, nine, nine, nine, nine.’ Rebel troops launched an assault on Diem’s palace, where the president and his brother took refuge in the cellar. In Saigon, the plotters seized and shot several Ngo loyalist officers. At 4.30 p.m. Diem telephoned Lodge to seek his support, and received only the offer of a safe conduct out of the country.
The plotters phoned the president, urging him to quit in exchange for his life. Instead he contacted intimates, trawling for support which was not forthcoming. At eight o’clock that evening Diem and Nhu attempted a desperate gambit, slipping out of the palace and driving to Cholon through deserted streets, defying a curfew imposed by the army plotters. The two took refuge in a house prepared by Nhu for just such an emergency, with its own communications system: they were in Cholon when rebel troops shelled and finally stormed the palace, overcoming guards who died in defence of an absent Diem. Only after hours of fighting was the wrecked building secured, then looted of everything from Madame Nhu’s negligees to the president’s impressive collection of American comics.
At 6 a.m. on 3 November, an audibly exhausted Diem telephoned ‘Big’ Minh and offered to negotiate terms for his resignation. The generals rejected the proposal, likewise a suggestion that he should be allowed to leave the country with the public honours due to the head of state. Minutes later, Diem called again: he and his brother had decided to surrender unconditionally, and were to be found at St Francis Xavier, a Catholic church in Cholon. The generals, uncertain what they should do with their redundant president, turned to Lou Conein. He said it would take twenty-four hours to produce an American plane to fly Diem out, and they would need to find a country willing to grant him asylum.
