Prince Harry and Jill Biden teamed up to host a virtual event in honour of Warrior Games athletes and their families on Monday.
The Duke of Sussex apologised to those at the online meeting after the games - a sports tournament for injured service personnel - were cancelled because of the coronavirus pandemic and admitted he'd been looking forward to the event, which inspired his own Invictus Games.
Speaking from his California home, he told those gathered: "I am so sorry that we're not all together at the Warrior Games where we should be.
"The pandemic has certainly changed or flipped life upside down for so many people.
I will never forget that first visit that I had to the Warrior Games, which inspired me to create the Invictus Games [which] never would have been created had I not been inspired by every single one of you, and your companions, and the families for everything that you give to the service of this country."
