A Grave Mission Back to Vietnam

Some 300,000 Vietnamese casualties were never found. A local veteran is consumed with helping to track them down.
Thousands of miles and half a century separated retired Sgt. Bob Conner from his former duty station at Bien Hoa Air Base, Vietnam. An unexpected email brought him back - but for a very different mission.

he search consumes him now, almost 50 years after Bob Connor smelled the stench of their piled, rotting bodies from across the base and then went back to his duties.

For hours on end and days that bleed into nights, the 70-year-old retired facilities manager sits at the computer in his Maple Shade, N.J., apartment, poring through vast troves of data, military records, and maps in search of clues about where long-missing bodies of Viet Cong and North Vietnamese soldiers might be buried.

For Connor — a U.S. Air Force veteran of the Vietnam War — this is more than a quest. It is a question of humanity.

In the United States, the Vietnam War has been etched into the fabric of an entire generation and is fading into history books. All but 1,603 American casualties have been found, their remains laid to rest. But in Vietnam, the final chapter of the war remains unwritten, families and comrades unsettled as nearly 300,000 soldiers are still missing, according to the Vietnamese government.

Many of the missing were buried in mass, unmarked graves dug by their former enemies — American servicemen. In a twist of internet serendipity, the Vietnamese government found Connor and asked him and other veterans to help locate the unmarked graves, to give thousands of Vietnamese families the closure that has eluded them for five decades.

Connor has answered that call with obsessive urgency. His mission to bring comfort to the families of his former enemies has taken him halfway around the world, alienated some Vietnam veterans, and unearthed vivid memories of the futility and horror of a war that ended long ago.

'The colonel will be in touch'

Connor was not out looking to start a new mission at this stage in his life.

He had been helping his granddaughter with a school project about the Vietnam War when he searched Google Earth for Bien Hoa Air Base, where he had served in 1967-68 as a sergeant with the U.S. Air Force Security Forces.

In the interest of cataloging history, Connor left a comment — and his email address — on one of the photos of Bien Hoa. He didn't really expect anyone to see it.

Using a now-defunct service called Panoramio that allowed users to augment Google Earth maps with personal photos, Connor left a comment – and his email address – on one of the photos of Bien Hoa. Click here to see his full note.

"Significant battle took place here at the start of the Tet Offensive '68," he wrote. "Those VC [Viet Cong] killed had to be buried in a mass grave at the end of the runway."

Ten days later, an email arrived from Vietnam.

It was from Che Trung Hieu, a 70-year-old veteran of the North Vietnamese People's Army, who was "very excited to hear about the grave because they knew nothing about it," Connor said. "So he's in shock, and I'm in shock, and he says, 'The colonel will be in touch with you.' "

Connor, who had been honorably discharged from the Air Force in 1969 and has been perfectly happy enjoying retired life since 2003, had no idea who "the colonel" was or what he had gotten himself into.

"I damn near s—," Connor said. "I thought, 'What did you do, you idiot?"

Soon after, he got another email. Col. Mai Xuan Chien — deputy political commissar of the military command in the province where Bien Hoa is located — said the Vietnamese government had been searching the area for decades with no success.

"We are so glad because over 40 past years, we have so many times searched and excavated along the perimeter of Bien Hoa Air Base, but we didn't find any of the mass graves," Mai wrote. "Would you please contact other veterans to give us more specific information?" Click to read the entire letter.

'You have to get by that bitterness'

In Vietnamese culture, soldiers who die in war but remain unaccounted for are referred to as martyrs. Their spirits are believed to wander between this world and the next until their bodies are found, identified, and properly entombed. Only then can they be called heroes.

Mai said first-person accounts were one of Vietnam's best resources for finding mass graves.

Retired Sgt. Bob Connor describes his experience during the Tet Offensive at Bien Hoa Air Base, Vietnam.

"Veterans of the United States who are witnesses ... are the best clues, with their memory, souvenirs, photographs, and even their hearts of humanitarians," Mai wrote in an email to the Inquirer and Daily News, "along with the generosity and sympathy sharing the pain of war between two peoples of Vietnam and the United States."

Connor thought it strange that people in Vietnam would put so much faith in his word alone. It was an honor he did not take lightly.

He scoured the internet for other veterans who could have more detailed information about the mass grave at Bien Hoa, or any other mass graves in Vietnam. He posted on military Facebook pages and message boards. He sent emails and contacted website administrators.

Many times, he received no response. Sometimes, the responses were hostile.

"Let those stinking commies lay where they are," one Vietnam veteran wrote back to Connor. "I won the nation's 5th highest award for heroism … and killed as many of those commies as I could."

Connor hit roadblocks at every turn until one veteran put him in contact with retired Col. Martin Strones, who had been a captain of the U.S. Air Force Security Forces at Bien Hoa during the Tet Offensive battle and had been awarded the Silver Star for valor in combat.

On base after the attack, it had been Strones' job to count the enemy bodies.

"If you can imagine 150 bodies deteriorating rapidly in the sun, it's just a terrible stench — and then the animals start," he said. "It was almost impossible to breathe out there because of the smell."

Strones oversaw the gathering of the bodies, which were buried in an unmarked grave on the edge of the base.

Then, he went on with his duties — and his life.

"I never really dwelled on the mass grave," he said. "In fact, until Bob brought it up, I really hadn't thought about it."

What Strones, 77, had thought about was returning to Bien Hoa Air Base.


"I've wanted to go back for many, many years. I don't know if I can explain why to anybody who was not in the military," he said. "It's the same reason why people go back to Normandy."

Strones spent 30 years in active duty and reserve service with the U.S. Air Force and now runs a security consulting company, Strones Enterprises Inc. He had tried at least three times to get back on Bien Hoa Air Base, about 20 miles northeast of what was then Saigon, but was denied access because the site is an active Vietnamese military installation.

In December, Strones, of Clinton, Tenn., received Connor's email, asking him to help locate the mass grave at Bien Hoa. Strones didn't hesitate to help.

"I know some people are still bitter, but we were doing what we were told. Some people are mad at the U.S. government for that, and some people are mad at the Vietnamese for that," Strones said. "I understand. But you have to get by that bitterness. If I'd have lost a son, I'd want to know where he ended up."

Enemies no more

Connor and Strones were invited to Vietnam in March by Mai and the Dong Nai Province People's Committee to help identify the grave at Bien Hoa.

“The common thread between us was that the war was over, and we were friends.”

At their first meeting, Mai — dressed in full uniform — saluted the Americans. He made it clear, Connor said, that the Vietnamese held no ill-will toward U.S. veterans.

"He wanted us to know that they understand and respect what we had to do during the war," Connor said. "He only said it once, but you had that feeling the entire time we were there with him."

When Connor met Che, the man who wrote the email that started his transcontinental odyssey, he was overcome with emotion.

"It's a funny feeling, when you're face to face with your enemy, completely," Connor said, fighting back tears. "The common thread between us was that the war was over, and we were friends. We had just never met. And we're meeting now for the very first time."

When Strones and Connor accompanied Mai and his group to try to locate the grave, they became the first Americans since the war to set foot on Bien Hoa Air Base. Even one of the deputy prime ministers, Truong Hoa Bình, came to the base to meet them and oversee the excavations.

After four days, they were unable to pinpoint the grave. Strones and Connor returned home deflated.

"I think they thought I could go right to the spot and say, 'Dig here,' " Strones said. "But I had told them more than once, 'I believe I can find it, but we didn't mark it, and it's been 49 years.' "

Connor was crestfallen.

"I was frustrated and ticked off because we couldn't find the grave," he said. "But they weren't upset."

Mai said that knowing the U.S. veterans were leaving his country so despondent only strengthened his people's resolve to find the grave.

"Mr. Martin Strones and Mr. Bob Connor had to return their country in an uneasy and unsatisfactory status," he said. "We did share those mood of them and determined to expand the search area."

Three weeks later, the mass grave of "relics and rotten bones" was uncovered at Bien Hoa, just 20 meters from where Strones said it would be, according to Mai.

The discovery proved to Che that Connor and Strones were "good, wonderful guys who help bring home the Martyrs who lay down under cold place nearly 50 years."

Dao Le Phuong, press and cultural attaché for the Vietnam Embassy in Washington, D.C., confirmed — in an email to the Inquirer and Daily News — the finding of "mass graves of Vietnamese martyrs" at Bien Hoa, "with the support of two American veterans, Bob Connor and Martin Strones."

While the grave was believed to have contained about 150 soldiers, the Vietnamese government was able to identify only 72 of the martyrs, and to contact their family members, Che said.

"The rest we will continue to contact and find their families, but it is difficult because, after 50 years of war, many families are scattered," he said.

On July 12, a reburial was held in Vietnam for the 72 soldiers who, thanks to their former enemies, are wandering spirits no more. Relatives of the dead came clutching photos of their loved ones, incense filled the hot air, and 72 small coffins — all draped in Vietnamese flags — were aligned in perfect rows.

"The memorial service was so emotional," Che said, "more than 1,500 attenders and martyrs' families from 23 provinces."

Le Anh Toan, the brother of one of the soldiers found in the mass grave, said that in 1968, his family had received nothing more than a death notice.

For "50 years, our family has looked for our brother. Now we know his resting place amongst his comrades. We can finally be at peace," he told the Viet Nam News, a daily English newspaper in Hanoi.

Phung Duy Cuong, who fought at Bien Hoa for the North Vietnamese People's Army, said the soldiers who had died beside him that day were like brothers.

“We come from different places, we are not blood relatives, but we might as well be,” he told the paper. “The day we found our comrades feels like the day we found our family."

Strones' piercing blue eyes still well up when he talks about watching footage of the reburial.

On July 12, a reburial was held in Vietnam for the 72 martyrs who, thanks to their former enemies, are wandering spirits no more. At the ceremony, U.S. veterans Bob Connor and Martin Strones spoke to attendees via a video stream.

"To see those people standing with an 8-by-10 picture of their loved one — I'm so glad I was able to do that, to give them closure," he said. "People sent me emails saying, 'God bless you for coming to Vietnam and helping us heal the wounds.'"

Laying the dead to rest is "an important part of healing deep wounds," Ted Osius, U.S. ambassador to Vietnam, said in a statement.

"When people from both countries, who were once on opposite sides of the battlefield, are able to move on, become friends, and work together to pay respect to the fallen and bring a sense of closure to these families," Osius said, "that sends a powerful message."

'A profound humanitarian issue'

Today, Strones continues to speak to military groups about his humanitarian mission, in part to try to find others who may know about additional graves in Vietnam.

Meanwhile, Connor — who came home from the Vietnam War feeling like he hadn't made a damn bit of difference — now spends up to four hours a day hunting the internet, trying to get other veterans to come forward.

"For those who have seen grotesque war atrocities, that's a hard pill to swallow. I admit that," Connor said of veterans' helping a former enemy. "They need to break away from that last thought of the guy who died beside them and think of the families in Vietnam that deserve closure."

What started as just one man on an unlikely mission has grown. Connor is now working with four other Vietnam veterans he found on the internet who have insight into additional mass graves in Vietnam. He and Strones have also provided information on several other mass graves containing as many as 3,000 soldiers, though those sites have yet to be excavated, Che said.

Connor hopes the U.S. government will also step up and provide intelligence it may have on mass graves in Vietnam, "or else this whole thing is going to take another 50 years."

Dao, of the Vietnamese Embassy, called the exchange of information "a profound humanitarian issue."

"Continued cooperation between the two countries on these humanitarian issues," he said, "serve the interest and wishes of our two people and help deepen our ties and relations."

Lee Tucker, a spokesman for the Defense Department's POW/MIA Accounting Agency, said in an email that, since 1988, the U.S. has conducted joint recovery operations with Vietnam for missing U.S. soldiers and citizens, and does so four times a year.

"The progress we have made in accounting for our personnel still missing from the war in Vietnam would not be possible without the support of the Vietnamese people and its government," Tucker wrote. "For that, we are very appreciative."

In 2015, the U.S. Agency for International Development signed a statement of cooperation with the Vietnam Academy of Science and Technology, which included a $980,000 grant to help advance the country's ability to identify remains.

While POW/MIA is aware of Connor and Strones' endeavor and is "supportive of the mission from a humanitarian perspective," Tucker said, the agency takes no official position on their actions.

"It is important to remember," he wrote, "these are efforts by veterans acting on their own."
