Marine engineer George Johnson Armstrong on this date in 1941 was hanged at Wandsworth Prison … attaining an unenviable distinction as the first of five Britons executed under the Treachery Act of 1940.
One of the very first laws enacted by the incoming wartime government of Winston Churchill as the Wehrmacht overran France, the Treachery Act anticipated two potential difficulties in punishing various forms of aid that folk might thereafter attempt to extend to the Third Reich.
We’ll let all about those difficulties:
if we rely upon the Treason Act — the main Act, as I have said, is an Act of great antiquity — and other Acts which establish special procedure and special formalities, we shall have a much more complicated and cumbrous procedure than may, in existing circumstances, be justified.
There is also this further point. The law of treason in this country applies, of course, to every British subject wherever that British subject is living, because every British subject owes allegiance to the King. The law of treason also applies to aliens in so far as they owe to the King local allegiance — that is to say, as long as they are resident in this country and enjoying the protection of its laws. It is a very doubtful question indeed whether under the existing law of treason you could proceed against an alien who has come here suddenly, surreptitiously by air or otherwise, for the purposes of wreaking clandestine destruction or doing other acts against the safety of the real. In as much as treason is a crime committed by someone who owes allegiance, it might be well argued that such a person does not owe allegiance to the British Crown.
This act was handy indeed against enemy spies like Josef Jakobs, but it was also employed against five British citizens during and immediately following the war. (We’ve previously met a couple of them in these very pages: Theodore Schurch and Duncan Scott-Ford.) Johnson’s particular offense was to communicate an offer to a German consulate in the United States to help keep the then-still-neutral U.S. out of the war.
