Recipients in attendance included Warrant Officer Class 2 Kim Hughes, who was awarded the George Cross in 2010 for his work as a British Army bomb disposal expert during the Afghanistan conflict.
And former Australian soldier Ben Roberts-Smith, awarded the Victoria Cross in 2006 for his gallantry in Afghanistan while destroying Taliban machine gun positions. Roberts-Smith became the most highly-decorated member of the Australian Defence Force.
Australian soldier Corporal Daniel Keighran, who was awarded the Victoria Cross for his actions during the Battle of Derapet in 2010 said: "It is incredibly humbling to talk to these guys and hear their stories, To be a part of that group as well - I don't think I'll get used it. Every year there are less and less members, so it's good to come together."
The biennial gathering of the association's members is a timely reminder of the sacrifices of members of the armed forces and civilians in times of war and the prince was clearly fascinated and moved by the stories they had to tell.
