In 1997, Princess Diana walked through an open minefield in Dirico to raise awareness of the danger and prevalence of landmines. The famous photo of her doing so served as a catalyst in banning the deadly weapon.
"If an international ban on mines can be secured it means, looking far ahead, that the world may be a safer place for this generation's grandchildren," Diana said in 1997. 22 years on, Harry walked in his mother's footsteps and described the experience as "incredibly emotional".
"It's incredibly emotional to follow in the footsteps of my mother... If 20 years ago she hadn't done what she did, this would still be a minefield. To see this as a thriving community is amazing," he said.
Now, Harry is reconnecting with The Halo Trust amid the pandemic to let them know their "dedication and determination" has not gone unnoticed in a heartfelt letter, according to ITV News royal editor, Chris Ship.
"In these trying times, hope comes from the light of our common humanity. Nowhere is that light burning brighter than at The Halo Trust. As countries closed their borders, lockdowns came into force and international travel became harder, many might have chosen to suspend operations. Instead, Halo kept open a presence in all 25 of its country operations," Harry wrote in the letter.
He added: "Halo might just have stuck to its core role, but I would also like to salute you for pivoting so quickly to meet the challenges unexpectedly presented by the pandemic. The fact that you can operate across conflict-affected countries like Afghanistan is also a precious resource in the face of a disease that recognises no frontlines.
"It is at times like this that the work and efforts of people like you – prepared to do whatever it takes to help, serve and protect others – shines through. In sometimes hazardous and dangerous situations, your commitment to your communities and people who need your help is remarkable. I am hugely proud to be able to support such an extraordinary organisation."
Though Prince Harry and Meghan Markle are currently settling into their new life in Los Angeles, the couple has kept up with their patronages and charities.
