It wasn't only civil unrest that Churchill needed to worry about, but that of the British Establishment also, witness the gathering of VSOs (including a Royal Prince) at Dungavel, the home of Douglas Douglas-Hamilton, 14th Duke of Hamilton, and a Wing Commander Sector Commander for Scottish Air Defence. He was on duty that night at RAF Turnhouse and so not present when the party gathered by the briefly lit airstrip at Dungavel. The inbound aircraft never landed though, having crashed further south at Eaglesham. Its pilot had bailed out and been detained by the military, giving his name as Alfred Horn and a friend of the Duke, whom he asked to see. It later became clear that he was the Reich Deputy Fuhrer, Rudolf Hess.
Churchill later announced to the House:-
When deputy Führer Hess came down with his aeroplane in Scotland on 10 May, he gave a false name and asked to see the Duke of Hamilton. The Duke, being apprised by the authorities, visited the German prisoner in hospital. Hess then revealed for the first time his true identity, saying that he had seen the Duke when he was at the Olympic games at Berlin in 1936. The Duke did not recognise the Deputy Führer. He had however, visited Germany for the Olympic games in 1936, and during that time had attended more than one large public function at which German ministers were present. It is, therefore, quite possible that the deputy Führer may have seen him on one such occasion. As soon as the interview was over, Wing Commander the Duke of Hamilton flew to England and gave a full report of what had passed to the Prime Minister, who sent for him. Contrary to reports which have appeared in some newspapers, the Duke has never been in correspondence with the Deputy Führer. None of the Duke's three brothers, who are, like him, serving in the Royal Air Force has either met Hess or has had correspondence with him. It will be seen that the conduct of the Duke of Hamilton has been in every respect honourable and proper.
So nothing to see here, move along please.
