Gentlemen, start your engines.” The laconic command copied from the Indianapolis 500 auto races, echoed from the 1MC, the public-address system of the U.S.S. Hancock. Moments later, the Commanding Officer of Marine Heavy Helicopter Squadron 463, LtCol. Herbert Fix, lifted his CH-53D Sea Stallion off the deck of the aging carrier. When the other seven choppers in his squadron had left the deck, they fluttered off in a tight formation through blustery winds and dark, ominous rain clouds that hovered over the South China Sea. Operation “Frequent Wind,” the emergency evacuation of the last Americans in Saigon was under way.
The rescue operation had been delayed as long as possible-too long, in the view of many Pentagon officials. In recent weeks 44 U.S. Navel vessels, 6,000 Marines, 120 Air Force combat and tanker planes and 150 Navy planes had been moved into the area. Nevertheless, Secretary of State, Henry Kissenger and the U.S. ambassador in Saigon, Graham Martin, argued that the final withdrawal of the American community would probably set off a wave of panic in Saigon and hasten the fall of the South Vietnamese government.
During the preceding eight days, U.S. planes had evacuated almost 40,000 American and South Vietnamese refugees from Tan Son Nhut airbase near Saigon. By last week, the airlift was growing increasingly dangerous. Artillery shells and rockets closed Tan Son Nhut airport Monday morning, April 28, 1975. The next day, an U.S. C-130 transport was hit by a rocket on the runway and burst into flames as the crew escaped. A short time later, two Marine Corporals, Cpl. N. McMahon of Massachusetts and LCpl. D. Judge of Iowa, guarding the US defense attache’s compound at Tan Son Nhut, were killed by Communist artillery.
News of the destruction of the C-130 and the Marines’ deaths reached President Ford during a meeting with his energy and economic advisers. He scribbled a note to the deputy director of the National Security Council, LtGen. Brent Scowcroft: “We’d better have a NSC meeting at 7.”
Plainly, evacuation by commercial flights, by military airplanes or by sea was no longer feasible. The security advisers discussed whether conditions might permit a resumption of the military airlift. If not, they would have to go a fourth option, the riskiest of all: evacuation by Marine helicopters. Scarcely two hours after the meeting ended with no decision, Ford learned that two C-130s attempting to land at Tan Son Nhut had been waved off; the airport was blocked by thousands of panicky South Vietnamese, by then all of Ford’s advisers, including Martin agreed that it had to be “Option Four.” At 10:45 p.m., the President ordered Operation Frequent Wind to begin.
Kissinger telephoned Ford to report that a fleet of 81 helicopters was about to embark on its mission, then, at 1:08 a.m. Tuesday, he called again with the news that the evacuation had begun. In Saigon, the center of activity for much of the day was the landing at Tan Son Nhut airport, a tennis court near the defense attaché’s compound. Landing two at a time, the helicopters unloaded their squads of Marines* 860 in all, who reinforced the 125 Marines already on the scene* and quickly picked up evacuees.
As the operation continued, many helicopters came under fire. Most evacuees sat in cold panic as their choppers took off. “For the next three minutes as we gained altitude,” reported TIME Correspondent William Stewart, “we held our breaths.” We knew the Communists had been using heat-seeking missiles, and we were prepared to be shot out of the sky. As I turned around to see who was aboard, Buu Vien, the South Vietnamese Interior Minister, smiled and gave a thumbs-up signal. “Forty minutes later we were aboard the U.S.S. Denver, a landing-platform dock, and safe.” By nightfall, the mission had been completed at Tan Son Nhut, but the evacuation of the embassy was still to be accomplished. Sheets of rain were pelting the city, and visibility had dropped to barely a mile. Some choppers had to rely on flares fired by Marines within the embassy compound to find landing zones; others homed in on flashlights.
Through Tuesday night, the Vietnamese crowd grew uglier, hundreds tried to scale the ten-foot wall, despite the barbed wire strung on top of it. Marines had to use tear gas and rifle butts to hold back the surging mob. Some screamed, some pleaded to be taken along. Floor by floor, the Marines withdrew toward the roof of the embassy with looters right behind them. Abandoned offices were transformed into junkyards of smashed typewriters and ransacked file cabinets. Even the bronze plaque with the names of the five American servicemen who died in the embassy during the 1968 Tet offensive was torn from the lobby wall. Marines hurled tear-gas grenade into the elevator shaft; at time the air was so thick with tear gas that the helicopter crews on the roof were effected.
By that time, tempers were frayed in Washington as well as in Saigon.
Martin had drawn up a list of 500 Vietnamese to be evacuated; he refused to leave until all were safely gone. His delay prompted one Administration official to quip, “Martin got all 600 of his 500 Vietnamese out.” Finally, at 5:00 p.m., Washington time* it was 5:00 a.m., in Saigon* Kissinger told the president that Martin was closing down the embassy and destroying its communications equipment. Minutes later, Lady Ace 09 landed on the embassy helo pad and Ambassador Martin boarded the helicopter as Major James Kean urged the CH-46 pilot Captain Berry, to please be sure someone comes for them. After lift off, Captain Berry broadcast the message; “Lady Ace Zero Nine, Tiger-Tiger-Tiger.”
As many as 130 South Vietnamese planes and helicopter, including F-5 fighter-bombers, transports and attack planes, were reported meanwhile to have reached the US run Utapao airbase in Thailand with about 2,000 soldiers and civilians; already some 1,000 Cambodian refugees were crowed into tents there. Alarmed, the Thai government announced that the refugees had to leave within 30 days and that it would return the planes to “the next government in South Vietnam.” Defense Secretary James Schlesinger firmly advised Bangkok that it should do no such thing; under aid agreements, the equipment cannot be transferred to a new government but must revert to U.S. possession.
By the end of the week, another seven or so South Vietnamese helicopters had landed or tried to land on the U.S. naval vessels. One South Vietnamese pilot set his chopper down on top of another whose blades were still turning. Others ditched their craft and had to be fished out of the water.
An American search-and-rescue helicopter, Swift-14, BUNO 154042 (HMM-164) from the U.S.S. Hancock (CV-19) crashed at sea at 2330, April 29, 1975 and two of its four crewmembers, Captain William C. Nystul and First Lieutenant Michael J. Shea were listed as missing in action, possible the last American fatalities of the war. The remaining two, Cpl. Stephen R. Wills, Crew Chief and right gunner and Cpl. Richard L. Scott, left gunner, were rescued by another CH-46, Swift 07, during a zero visibility, night water landing to pick up the two wounded Marines.
“The last days of the evacuation were very hairy indeed,” Ford confesses afterward. “We were never sure whether we were going to have trouble with the mobs.” As Ford noted, the whole operation had gone better “than we had any right to expect.” According to the Defense Department, 1,373 Americans and 5,680 South Vietnamese* many more that the US had originally intended* had been removed. Another 32,000 desperate Vietnamese had managed to make their way by sampan, raft and rowboat to the US ships offshore, bringing to about 70,000 the number evacuated through the week.
For the next three hours the Marines wait, and grow more concerned as they discover no one responds to their radio signals. Finally, after they have resigned that they will not be rescued, and have voted to make an Alamo-like stand, the Marines hear the familiar sound of rotor blades slapping the humid air, a CH-46 Sea Knight, and two AH-1G Cobra escorts come in to view. Dodging small arms fire and using riot control agents against people attempting to force their way to the rooftop, Major Kean and his 10 Marines boarded a HMM-164 CH-46 helicopter, Swift 2-2. After closing the ramp, Swift 2-2 (piloted by Captains Holden and Cook, and crewed by Sergeant Stan Hughes, left machine gunner and Sergeant Chris Woods, Crew Chief and right gunner) lifted into a hover and the pilots were overcome by CS gas had to set back down on the embassy helo pad. Regaining their composure, Captain Holden lifted the helo and departed the embassy rooftop. The last American helicopter to leave South Vietnam, Caption Holden radioed the last official message from Saigon: Swift 2-2 airborne with 11 passengers, ground security force onboard. Clearing antennas and church steeples, Swift 2-2 picked up the Saigon River and descended to tree top level and followed the river out to the awaiting American Forces. During the flight along the river, Sergeant Woods sighted approximately eight communist tanks, parked side-by-side, waiting until the eighth hour to enter the city. Checking his watch, Major Kean noted that it was two minutes until eight, only 23 hours since the NCOIC of Marine Security Guard, Manila, had called him to relay a message from his wife in Hong Kong that she was pregnant. Only 32 minutes later on that unforgettable day, 30 April 1975, the 11 Marines exited Swift 2-2 onto the deck of the U.S.S. Okinawa.
Disembarking, many on board the Okinawa, the consensus was why so much time had elapsed between the arrival of the Ambassador’s flight and Swift -2-2, well over two hours. Had someone forgotten these Marines were still at the Embassy? The answer is no. The intention was to remove the Ambassador while some security still remained at the Embassy, and then have other helicopters pick up the remaining Marines, but it appears that when Captain Berry’s aircraft transmitted “Tiger is out,” those helicopters still flying, including Captain Walters who was orbiting the Embassy at the time the Ambassador left, thought the mission was complete. This particular transmission had been the preplanned code to indicate when the Ambassador was on board a helicopter outbound to the task force. Having waited so long for his departure, this transmission caused some to conclude that he had departed as part of the last group to leave the Embassy. Captain Berry late explained that radio message ” ‘Tiger-Tiger-Tiger’ was the call to be made when the Ambassador was on board and on his was out of Saigon. It had absolutely nothing to do with the cessation of the operation. We had originally planned to bring the Ambassador out on the afternoon of the 29th.”
At this juncture, thinking the mission complete and the Ambassador safe, Captain Walters headed back to the USS Okinawa. Subsequent to his landing at approximately 0700, the command realized that Captain Walters did not have the remaining Marines on board. Due to a misunderstanding and miscommunication, they were still at the Embassy. General Carey immediately recycled the HMM-164 CH-46 “Swift 2-2”, but by this time due to the ships’ offshore movement, the time required to reach the Embassy exceeded 40 minutes. With two hours of fuel on board, the CH-46 did not have any room for error. Swift 2-2 landed on the USS Okinawa with two “LOW FUEL” lights, or 20 minutes of fuel remaining.
To the Marines waiting in Saigon, attempts by the South Vietnamese to reach the rooftop kept them busy and as a consequence, they did not notice the extended gap between the flights. Major Kean later stated that he and his Marine did not become alarmed because they knew that another CH-46 would arrive. “We never had a doubt that our fellow Marines would return and pick us up. They had been doing it all night long.”
