Mr Hagan, 91, had an outstanding career in the Royal Marine Commandos in the Second World War, and he served all over the world.
He landed in Normandy, France, on D-day in June 1944 and they were under fire for 83 days before the enemy was overcome. His career in the Commandos extended from 1942 into the post-war period into 1946.
Pat was presented with the medal at the Royal Albert Hall, London, earlier this month.
The presentation was made in one of the boxes in the auditorium by Royal Marines Corps Regimental Sergeant Major, the Senior RSM, WO1 (RSM) PS Gilbey RM.
Pat’s military service has meant so much to him and he has taken part in many events since the war, meeting and helping his colleagues and telling people of the life of a commando.
