A U.S. Marine’s 1,000-mile trek through Britain ended with a warm embrace from Prince Harry.

Kirstie Ennis, 24, had just participated in the Walk with the Wounded -- traveling by foot from Scotland to Buckingham Palace -- when, at the end of her journey, she gifted the royal with a dog tag of a fallen soldier she knew.

“No I can't, I can't accept this," an overwhelmed Harry said before embracing Ennis, who was severely injured in a 2012 helicopter crash in Afghanistan.

"Please, you know what this means to me, I want you to," she replied.

The dog tag she gifted to the prince, who himself did two tours in Afghanistan, was to honor Corporal Baune, who died in 2012 after his unit was hit with an IED.

"I look at situations like that, he never came home, he had a wife and a family but he never came home,” Ennis told reporters. “The six of us here today did come home, we are actually the lucky ones. The least we can do is share their legacy and honor their memory.”

"Harry was reluctant to accept it at first because he knows how much it means [to me],” she added. “He has helped me lay a couple of them and was hesitant to take them as he knows how much it means to me. I told him he had to."

In September, Harry chose to ring in his 31st birthday by spending time with WWII veterans, attending an event to mark the Battle of Britain with them in England. Watch below:
