George Johnson Armstrong
George Johnson Armstrong was the first British citizen to be executed under the Treachery Act 1940. Only four other British subjects were executed under this Act; saboteur Jose Estelle Key, Duncan Scott-Ford, Oswald John Job and Theodore Schurch.
Armstrong was an engineer by occupation. He was tried on 8 May 1941 at the Central Criminal Court and convicted for communicating with the German Consul in Boston, Massachusetts, to offer him assistance before the United States entered the Second World War.
His appeal on 23 June 1941, at the Court of Criminal Appeal, was dismissed, and on 10 July 1941 at the age of 39 Armstrong was executed by hanging at HM Prison Wandsworth by Thomas Pierrepoint.
