Their Royal Highnesses Duke and Duchess of Sussex have watched a charity performance for veterans with the former Army Chief, Lord Dannatt.
The royal couple sat with Lord Dannatt at the concert in London called '100 Days To Peace', which was to mark the final days of World War One.
The show was to raise money for three mental health charities.
Lord Dannatt led the Army between 2006 and 2009, during which Prince Harry started his first of two tours in Afghanistan in 2007.
Soprano Lesley Garrett performed a WB Yeats poem, and Sir Karl Jenkins was to conduct 'The Armed Man: A Mass For Peace' - an anti-war piece performed by choir and orchestra.
Garrett praised Harry for highlighting mental health issues and supporting veterans.
"We did sign up before we knew Prince Harry and Meghan would be here," she said.
"It's so important to support these amazing charities."
Lord Dannatt, accompanied by his wife, spoke warmly with the royal couple before they entered the Great Hall for the show.
The show, presented by the Royal Armouries Museum, raised money for Help for Heroes, Combat Stress and Heads Together.
