Operation Brother Sam

Operation Brother Sam was a covert US military operation in which the Johnson administration dispatched a naval task force to Brazilian waters in late March-early April 1964 to support the military coup that overthrew President Joao Goulart of Brazil. The task force, assembled under the direction of Dean Rusk's State Department, US Ambassador to Brazil Lincoln Gordon, and CIA director John McCone, included the aircraft carrier USS Forrestal (CVA-59), six destroyers, and tanker vessels carrying petroleum, aviation fuel, and military supplies intended for use by coup forces if needed. The coup succeeded without requiring direct US military intervention, and the task force was withdrawn, but its existence was suppressed for nearly two decades.¹

The coup was the most consequential US covert operation in Latin America before Chile 1973, installing a military dictatorship that held power until 1985 and opening the Brazilian Amazon to American corporate penetration.

Goulart's Brazil

Joao Goulart (known as "Jango") had been vice president under Janio Quadros and assumed the presidency in 1961 when Quadros resigned. He was a moderate nationalist who had proposed "basic reforms" including land redistribution, nationalization of oil refineries, restrictions on profit remittances by foreign corporations, and extension of the vote to illiterates. These positions were unacceptable to the Rockefeller network, which had major agricultural, banking, and industrial holdings in Brazil through IBEC, Chase Manhattan Bank, and affiliated corporations.²

President Kennedy had been hostile to Goulart but restrained in his interventionism, sending his brother Robert Kennedy to Brazil in 1963 to deliver a series of demands. Goulart, astonished by the similarity between Kennedy's demands and those of his domestic opponents, asked Robert Kennedy: "How can it be that you are in contact with my enemies?"³

Kennedy's assassination in November 1963 removed this restraint. The coup followed four months later.

Kennedy-Era Planning

Planning for Goulart's removal began in the Kennedy administration. At an Oval Office meeting on July 30, 1962, Kennedy met secretly with Ambassador Lincoln Gordon and State Department official Richard Goodwin to discuss strengthening military contacts with Brazil, including the appointment of Lt. Col. Vernon Walters as military liaison to Brazilian army officers. The meeting was among Kennedy's first secretly taped Oval Office sessions.⁴

On December 11, 1962, an NSC memorandum titled "U.S. Short-Term Policy Toward Brazil" outlined three policy options: doing nothing, collaborating to overthrow Goulart, or changing his orientation. An EXCOMM meeting the same day recorded Kennedy accepting the recommendation that "our best course of action is to seek to change the political and economic orientation of Goulart and his Government." The memorandum concluded that "coup must be kept under active and continuous consideration."⁵

On October 7, 1963, forty-six days before his assassination, Kennedy convened a White House meeting on Brazil with Under Secretary of State Averell Harriman, Secretary of Defense Robert McNamara, Assistant Secretary of State for Inter-American Affairs Edwin Martin, and Gordon. Kennedy asked Gordon directly: "What about the... Do you see a situation coming where we might be, find desirable, to intervene militarily ourselves?" Gordon responded that any such operation would be massive, estimating it would require "six divisions, I've forgotten how many ships and aircraft and whatnot, I mean, it was a really massive military operation."⁶

A contingency plan dated November 22, 1963 (the day of Kennedy's assassination) noted that the plan placed "heavy emphasis on U.S. armed intervention."⁷

Planning and Coordination

The coup's operational planning in 1964 involved several coordinating nodes:

Adolf Berle, operating from his Manhattan townhouse, was in radio contact with Brazilian military conspirators on the night of March 30, 1964, listening to reports of troop movements as the coup unfolded. Berle's companion Alberto Byington, a Brazilian-American businessman descended from Confederate emigrants to the Amazon, was tied to ALCOA's Brazilian bauxite operations and had channeled US funds to coup plotters since at least 1962.⁸

Lincoln Gordon coordinated with the CIA station and with Vernon Walters, the US military attaché, who had longstanding personal relationships with the Brazilian military officers leading the coup. On March 20, 1964, a White House meeting established that an aircraft carrier and tankers would be sent to support the opposition if needed. Gordon played a central role in ensuring the Johnson administration's early recognition of the junta.⁹

In FRUS document 186 (March 26, 1964, Secret/Priority, Embassy cable number 2084), Gordon reported on military tensions in Brazil, including Humberto Castello Branco's March 20 letter to senior officers opposing Goulart's alleged anti-democratic intentions. A footnote to the document records that Walters independently reported that conspirators had "agreed on seven grounds that could trigger a revolt" and had appealed for US assistance, which Walters declined, passing the information to Gordon instead.¹⁰

In FRUS document 187 (March 28, 1964, Top Secret/Immediate/Exdis), Gordon concluded that "Goulart is now definitely engaged on campaign to seize dictatorial power, accepting the active collaboration of the Brazilian Communist Party." He identified Castello Branco as leading "a military resistance group" with "prospects of wide support and competent leadership," explicitly recommended "clandestine delivery of arms of non-US origin" to Castello Branco supporters, and proposed deploying "a naval task force for maneuvers in south Atlantic" within steaming distance of Santos. He noted that "carrier aircraft would be most important for psychological effect."¹¹

J.C. King, the CIA's director of clandestine operations for the Western Hemisphere, coordinated US support for the coup alongside Berle. King had been active in Brazil since his Johnson & Johnson years and maintained extensive contacts in the Brazilian corporate and military establishment.¹²

AIFLD (American Institute for Free Labor Development), the AFL-CIO's CIA-funded Latin American arm, played a labor-politics role in the coup's preparation, through its Brazil representative Andrew McLellan. AIFLD had been training Brazilian labor leaders, some of whom participated in organizing the demonstrations that provided pretext for the military's intervention.¹³

McGeorge Bundy coordinated at the NSC level. At an NSC meeting on March 28, 1964 (NSAEBB 465, Document 11), Bundy stated: "we should not be worrying that the military will react."¹⁴

A Top Secret White House memorandum dated March 30, 1964 stated: "We wouldn't want the Brazilian military to move until we have everything in place."¹⁵

The Go Signal and LBJ's Orders

FRUS document 192 (March 30, 1964, Secret) records a report from Army Attaché Vernon Walters, who met with General Jose Pinheiro de Ulhoa Cintra at midnight on March 29. Cintra reported that it had been decided to take action "this week on a signal to be issued later." General Amaury Kruel (Second Army Commander) had expressed full agreement with resistance plans. Walters concluded: "ARMA expects to be aware beforehand of go signal and will report in consequence."¹⁶

On March 31, 1964, at 3:38 p.m., President Johnson spoke by telephone with Undersecretary of State George Ball. Johnson's recorded statements from this conversation (Johnson Library Recordings and Transcripts, Tape F64.21, Side B) include: "I think we ought to take every step that we can, be prepared to do everything that we need to do," "We just can't take this one," and "I'd get right on top of it and stick my neck out a little."¹⁷

The Joint Chiefs of Staff assigned the operation the internal codename "Brother Sam" on March 31, 1964.

The Task Force

FRUS document 198 (March 31, 1964, 2:29 p.m., Secret/Flash/No Distribution) is Dean Rusk's telegram to the Embassy in Brazil authorizing the naval task force deployment "in order be in a position to render assistance at appropriate time to anti-Goulart forces if it is decided this should be done." The telegram outlines three components:

First, US Navy tankers bearing POL (petroleum, oil, lubricants) dispatched from Aruba, with the first tanker expected off Santos on April 13, followed by three additional tankers at one-day intervals. The tankers included the USNS Santa Ynez and USNS Chepachet, with USS Truckee (AO-147) also deployed.

Second, a naval task force (aircraft carrier and two guided-missile destroyers expected April 10, plus four additional destroyers with task force tankers arriving approximately four days later) to conduct what Rusk described as "normal naval exercises."

Third, approximately 110 tons of ammunition, light equipment, and CS agent (tear gas) assembled for mob control, destined for Sao Paulo (Campinas), deliverable within 24-36 hours upon final orders using six cargo planes, six tankers, and six fighters.¹⁸

Rusk stated that actual POL unloading and the airlift would require "further development [of the] politico-military situation" in which "some group having reasonable claim to legitimacy could formally request recognition and aid."¹⁹

At 1:50 p.m. on March 31, 1964, Rear Admiral John L. Chew ordered the task force centered on the USS Forrestal to proceed toward the vicinity of Santos. The task force drew on the 4th Aircraft Carrier Division and the 162nd and 262nd Destroyer Divisions of the Second Fleet. The full naval component comprised the Forrestal, guided-missile destroyers USS Leahy (DLG-16) and USS Barney (DDG-6), and destroyers USS Charles R. Ware (DD-865), USS Allen M. Sumner (DD-692), USS Harwood (DD-861), and USS William C. Lawe (DD-763). The USS Forrestal departed Hampton Roads on April 1, 1964, at 07:00, headed toward coordinates 17 degrees N, 60 degrees W.²⁰

An Esso tanker bearing motor and aviation gasoline was also dispatched toward Santos. A CIA memorandum of conversation (April 1, 1964) records a White House meeting at which McNamara confirmed the naval task force had sailed and the ammunition airlift had been assembled in New Jersey with 16-hour deployment capability.²¹

Outcome and Withdrawal

General Castello Branco informed US contacts on April 1 that he did not need US logistical support. A Joint Chiefs memo the following day addressed the disposition of arms that had been assembled. FRUS document 198's authorization was rendered unnecessary by the coup's rapid success. At 5:22 p.m. on April 2, 1964, the order to disband the joint task force was issued. The USS Forrestal returned to Hampton Roads on April 8. The operation was publicly rebranded as a "Quick Kick" exercise.²²

FRUS document 206 (April 2, 1964) records an NSC meeting summarizing the Brazil policy response following Goulart's flight. FRUS document 208 (April 3, 1964, Top Secret) records a senior congressional briefing on the situation's resolution. The Johnson administration recognized the new military government within hours of Goulart's flight from Rio.²³

The operation's cost of $2.3 million for the tanker component was never reimbursed. Dean Rusk, in a subsequent telegram to Gordon (April 3, 1964), noted that operational costs "might have to be reimbursed by Brazil, but this did not occur."²⁴

Documents declassified beginning in the 1970s confirmed the task force's existence and its operational orders. The National Security Archive published the core documents as Electronic Briefing Book No. 118 ("Brazil Marks 40th Anniversary of Military Coup") in 2004, and Electronic Briefing Book No. 465 ("Brazil Marks 50th Anniversary of Military Coup") in 2014, providing the first systematic public access to the Kennedy-era planning record.²⁵

Consequences

The coup installed a military government that held power for twenty-one years (1964-1985). The dictatorship immediately opened the Brazilian Amazon to foreign corporate investment. IBEC's Brazilian operations expanded. Standard Oil of New Jersey obtained new Amazon concessions. The FUNAI, which replaced the corrupt SPI, was organized under military supervision and became the instrument through which the dictatorship managed and in many cases destroyed indigenous communities standing in the path of Amazon development projects.²⁶

The 1967 Summer Institute of Linguistics survey of "potentially hostile tribes" in the Brazilian Amazon was conducted at the military government's request, providing mapping intelligence for the Amazon's systematic "opening."²⁷

For Nelson Rockefeller, the coup's success represented the realization of a strategy he had been building since the Chapultepec conference in 1945, when he first created the institutional framework for US military domination of Latin America and assembled the personal network (Berle, King, the Latin American junta) that made the 1964 operation possible.²⁸
