Frank Buckles enlisted for World War I at 16 after lying about his age. He made it home again and ultimately became that war's last surviving U.S. veteran, campaigning for greater recognition for his comrades-in-arms before dying at 110.
Buckles had been advocating for a national memorial honoring veterans of the Great War in the nation's capital and asked about its progress weekly, sometimes daily.
"He was sad it's not completed," DeJonge said Monday. "It's a simple straightforward thing to do, to honor Americans."
When asked in February 2008 how it felt to be the last of his kind, he said simply, "I realized that somebody had to be, and it was me." And he told The Associated Press he would have done it all over again, "without a doubt."
He was back in Washington a year later to endorse a proposal to rededicate the existing World War I memorial on the National Mall as the official National World War I Memorial. He told a Senate panel it was "an excellent idea." The memorial was originally built to honor District of Columbia's war dead.
Born in Missouri in 1901 and raised in Oklahoma, Buckles visited a string of military recruiters after the United States entered the "war to end all wars" in April 1917. He was repeatedly rejected before convincing an Army captain he was 18. He was actually 16 1/2.
"A boy of (that age), he's not afraid of anything. He wants to get in there," Buckles said.
Details for services and arrangements will be announced later this week, but DeJonge said Buckles' daughter, Susannah Flanagan, is planning for burial in Arlington National Cemetery. In 2008, friends persuaded the federal government to make an exception to its rules and allow his burial there.
Buckles had already been eligible to have his cremated remains housed at the cemetery. To be buried underground, however, he would have had to meet several criteria, including earning one of five medals, such as a Purple Heart.
Buckles never saw combat but joked, "Didn't I make every effort?"
"We have lost a living link to an important era in our nation's history," said Secretary of Veterans Affairs Eric Shinseki. "But we have also lost a man of quiet dignity, who dedicated his final years to ensuring the sacrifices of his fellow 'Doughboys' are appropriately commemorated."
U.S. Sen. Jay Rockefeller called Buckles "a wonderfully plainspoken man and an icon for the World War I generation" and said he will continue fighting for the memorial Buckles wanted.
"He lived a long and rich life as a true American patriot," said U.S. Sen. Joe Manchin, "and I hope that his family's loss is lightened with the knowledge that he was loved and will be missed by so many."
The family asked that donations be made to the National World War One Legacy Project. The project is managed by the nonprofit Survivor Quest and will educate students about Buckles and WWI through a documentary and traveling educational exhibition.
More than 4.7 million people joined the U.S. military from 1917-18. As of spring 2007, only three were still alive, according to a tally by the Department of Veterans Affairs: Buckles, J. Russell Coffey of Ohio and Harry Richard Landis of Florida.
The dwindling roster prompted a flurry of public interest, and Buckles went to Washington in May 2007 to serve as grand marshal of the national Memorial Day parade.
Coffey died Dec. 20, 2007, at age 109, while Landis died Feb. 4, 2008, at 108. Unlike Buckles, those two men were still in basic training in the United States when the war ended and did not make it overseas.
There are no French or German veterans of the war left alive.
Buckles served in England and France, working mainly as a driver and a warehouse clerk. An eager student of culture and language, he used his off-duty hours to learn German, visit cathedrals, museums and tombs, and bicycle in the French countryside.
Buckles returned to Oklahoma for a while, then moved to Canada, where he worked a series of jobs before heading for New York City. There, he again took advantage of free museums, worked out at the YMCA, and landed jobs in banking and advertising.
In 1941, while on business in the Philippines, Buckles was captured by the Japanese. He spent more than three years in prison camps.
"I was never actually looking for adventure," Buckles once said. "It just came to me."
In spring 2007, Buckles told the AP of the trouble he went through to get into the military.
"I went to the state fair up in Wichita, Kansas, and while there, went to the recruiting station for the Marine Corps," he said. "The nice Marine sergeant said I was too young when I gave my age as 18, said I had to be 21."
Buckles returned a week later.
"I went back to the recruiting sergeant, and this time I was 21," he said with a grin. "I passed the inspection ... but he told me I just wasn't heavy enough."
Then he tried the Navy, whose recruiter told Buckles he was flat-footed.
Buckles wouldn't quit. In Oklahoma City, an Army captain demanded a birth certificate.
"I told him birth certificates were not made in Missouri when I was born, that the record was in a family Bible. I said, 'You don't want me to bring the family Bible down, do you?'" Buckles said with a laugh. "He said, 'OK, we'll take you.'"
He enlisted Aug. 14, 1917, serial number 15577.
