The royal newlyweds had been invited to present an award to Sergeant Ryan McCready. He was recognised for winning over Afghan locals – thereby keeping the Taliban out of the area.
Among the other VIPs attending were Prime Minister David Cameron, his wife Samantha, David Beckham and Gordon Ramsay.
Becks – with his two boys Romeo and Brooklyn – met Flight Lieutenant Mike Anderson who withstood a mortar attack to rescue six Afghan children. The football legend said of the encounter: “Everyone is proud of the guys who put their lives on the line for their country.”
But it was Harry, giving his most mature speech yet, who summed up the spirit of the evening.
“It’s often said of our Armed Forces that they are ordinary people doing extraordinary things. Well, I don’t entirely buy that.
“Ordinary people don’t brave monsoon conditions dangling on a winch line to rescue 13 people, each in turn.
“For that matter, ordinary people don’t put their lives on the line for distant folk, such as the Afghans, who need our help and are now turning their country round because of it.
He also paid tribute to the families left behind by servicemen.
“The strength and courage it must take to see your husband or your wife, your father or mother, son or daughter, head off into the unknown – and to support them doing it – I can hardly even imagine.”
He added: “Like my brother, I share many of the same hopes, the same aspirations to go on operations, and the same fears, as all those who serve our Queen and country.
“By an accident of birth, though, it falls to 564673 Captain Wales humbly to express – on behalf of my comrades-in-arms and people up and down the country – the admiration we feel for the extraordinary men and women we honour here tonight.”
