For his efforts in aid of the Allies Garbo received an MBE from the British; in an ironic twist of fate, following the war he ended up encountering one of his German handlers, who gave him the Iron Cross for his contribution to the German war effort; the Nazis never realized that Garbo had fooled them, and thus he earned the distinction of being one of the few people during World War II to receive decorations from both sides.
