Prince Harry Returns Sgt. Elizabeth Marks's Gold Medal to Hospital That Saved Her Life

Prince Harry made a special delivery on Wednesday.

The Invictus Games founder visited Papworth Hospital in Cambridge, England, to personally hand over the gold medal won by U.S. Army Sgt. Elizabeth Marks, who made headlines around the world on May 11 with her stunning gesture.

After winning gold in the 100-meter freestyle, Marks, 25, returned the medal to Harry and requested that he give it to the hospital that saved her life.

Just before the first Invictus Games in 2014, Sgt. Marks – who has been in the Army since she was 17 and suffered a serious hip injury in 2010 which left her with no sensation in her left leg – became ill with a serious lung condition and had to be put into an induced coma in London.

She told reporters in May of her ordeal: “I landed in London and became very ill very rapidly, I was in hospital in London and went into respiratory distress syndrome, they shipped a team down from Papworth who put me on to ECMO [extracorporeal membrane oxygenation] life support and that ultimately saved my life … I can’t thank the U.K. enough for having that kind of medical support and taking such good care of me.”

When the medical team arrived Wednesday, Harry asked them: “Am I right in saying she was given about a 35 percent chance of living?”

Dr Vuylsteke replied: “That’s generous,” adding, “We used a machine to support her and keep her alive, while antibiotics and other drugs were helping her to fight it.”

Harry continued: “Something else that she told me while we were in Florida – I don’t know whether you’ll agree to it or not – she said that it was a blessing in disguise landing in London and going to Papworth because Papworth is undoubtedly the best place for someone having this condition.”

“That’s very kind of her,” replied Dr Vuylsteke, who said: “We’ve got the best system in place to support this kind of problem. What’s quite amazing is in England we’ve set up a system a few years ago that offers that (treatment) to anybody. I’m not sure that she would have received the same services anywhere else (in the world). So, in her bad luck, she was very lucky.”

Harry then said: “From all of us, it’s just a huge, huge thank you to all of you.”

During the Games, Marks told PEOPLE how her moving moment unfolded.

“I’d talked to Prince Harry previously about finding a way to get that medal to Papworth,” she said. “I thought the one that was presented to me by him would mean the most. I wanted to thank them for saving my life.”

Marks previously told PEOPLE of Harry, “He’s a very nice, honest, good human being who is here for one purpose: to show the world that soldiers can move forward from their injuries, and to support them. He uses his fame and his influence to support soldiers.”
