Gorman was able to remove the body and take command of the tank. With the Firefly, he was able to complete the destruction of both the Tiger II and his disabled Sherman. He was awarded the Military Cross for his actions, while his driver, Lance-Corporal James Baron, was awarded the Military Medal. Gorman was promoted to the rank of captain. However, this account is contested by the German tank's gunner, Gefreiter Thaysen, who said that his commander ordered to back up, hitting the Sherman with its rear. Thaysen's testimony also contradicts Gorman finishing off the Tiger II with a Sherman Firefly and capturing the German crew. Later in the war, Gorman took part in Operation Market Garden, the unsuccessful attempt to break through German lines in the Netherlands and advance into Northern Germany. The Irish Guards were a leading part of the ground part of the operation and Gorman's tanks reached the bridge at Nijmegen before the operation was called off. Post-war career After the war, Gorman left the army and joined the Royal Ulster Constabulary. He was the district inspector for Antrim until 1955, when he became district inspector for Armagh. This was during the Irish Republican Army's Border Campaign. With the approval of John D'Alton, the Archbishop of Armagh, Gorman uncovered an IRA bomb factory hidden in St Patrick's Cathedral, Armagh. He was also responsible for liaising with MI5 and MI6. He left the police in the early 1960s to become head of security for the British Overseas Airways Corporation. He later became head of personnel, then manager of the airline's operations in Canada, and then manager for South Asia. He left the airline in 1979 and returned to Northern Ireland. Political career After an assorted career, during which he was for a time Chief Executive of the Northern Ireland Housing Executive, he was elected to the Northern Ireland Forum for Political Dialogue in 1996 as a top-up candidate from the Ulster Unionist Party list. He served as Chairman of the Forum from 1996 to 1998. In 1998 he was elected to the Northern Ireland Assembly for North Down and served as a Deputy Speaker of the Assembly. He resigned as Deputy Speaker in February 2002. Honours He was knighted in the Birthday Honours of 1998 and was a Deputy Lord Lieutenant (DL) of County Down.
