"The fact that he cared enough about it to write his stuff inside — his name and the ID number — it wasn't mine to keep," said Chiasson. "If he cared so much he wrote his own info inside, it was up to a matter of time."
Chiasson, 21, contacted Royal Canadian Legion Command in Saint John and the Canadian War Museum. He was led to Pte. George Johnson, a member of the North Shore Regiment in the Second World War.
This week, after a three-day search, the soldier and his helmet were reunited for the first time in 70 years when Chiasson took it to Johnson and his wife, Annie, at their home in Norton, N.B.
"They came to the door," recalled Chiasson. "He rolled right into the entrance area, just looked at me and said, `22694.' That's the first thing he said.
"I looked inside and that's the exact number it had written on it, so I knew I had the guy," said Chiasson. "It was just really nice to give something back."
Johnson and that helmet spent six years together on the battlefields of Europe, serving in England, France, Belgium and Germany during the Second World War.
The last time he wore the helmet was on the outskirts of Berlin in 1945. The war was over.
"I could have kissed it," said Johnson, 93, who struggles with speech due to a stroke a few years ago. "That's what it felt like.
"I can't explain it the way I feel … what it's done for me," he said with a smile.
"He just kept looking at it," said Johnson's wife, Annie. "I don't think he could hardly believe he did have it until Jordan showed him the name.
"But he told Jordan his rank number right away. He always remembered that. He's quite pleased to have it."
Johnson doesn't remember writing his name in the helmet and can't remember how it disappeared. He doesn't remember bringing it back to Canada after the war.
Chiasson says it "feels great" to have reunited Johnson with his helmet.
"I've been smiling ever since," he said. "My girlfriend says she's never seen my eyes light up so much.
"And it's nice to see an old fella with his eyes bright, looking at the thing he held 70 years ago and hasn't seen since."
