Mate, that does not support what you say.
Hewitt, a then serving army officer, was POSTED to Germany, where at the time there was a hefty British Army presence (I visited Munster in the early 80s and there were parts of town you did not want to visit in order to avoid aggressive, drunken squaddies), so a posting to a German base for a serving officer in a tank regiment was very, very, very normal. Hint, our military presence in Germany then included a whole heap of tanks, as the presumption was fighting a land war across the North German Plain, which needs tanks, which Hewitt commanded.
This is NOT a deportation, 'cos if it was I know a whole heap of folk who were "deported". FFS, my late father-in-law was "deported" to Germany, as he served in the Army over there.
◊◊◊◊ knows where Andy Ross was "deported" to when he served..
