Prince Harry was on Thursday, October 22 at St Paul's Cathedral in London in a ceremony marking the 75th anniversary of the creation of BritishArmy Bomb Disposal.
For the ceremony in the Cathedral he proudly wore his medals won during a military career which he ended last June.
After the ceremony, dedicated to the role of defusing explosives units in World War II, the Northern Ireland conflict, and Afghanistan (where the Prince served), Prince met with several of these deminers and veterans.
Among them, many badly injured and disabled soldiers, but also families who had their family members killed in service by explosives. A meeting that is reminiscent of the commitment of the Prince Harry for disabled war veterans, through  his organization "Walking with the Wounded".
