39-year-old Richard Foscolo had been working in an oil field in Ghani some 900 miles away from Tripoli when trouble broke out.
With their security team having deserted, and reports that the Black Shadow were on their way, father-of-three Mr Foscolo said it was a very tense time for him and his colleagues.
However, thanks to poor weather, an aircraft originally headed for another oil-field made a last-minute diversion, and took the 39-year-old to Tripoli Airport, where he boarded a special chartered plane bound for Gatwick.
He said: “Naturally I am delighted and relieved to be home with the family, though I am exhausted and feel as though we need some space.
“I’m grateful for all the help my family were given during my absence, from friends, family and in particular our local MP Alun Cairns.
“On the one hand there was a benefit of being in an isolated location and away from the troubles and the action, but then the isolation in itself brought its own threats and the danger that we could be forgotten about and that supplies could run short.
The Foreign Office estimates fewer than 500 Britons remain in Libya – including about 50 in and around Tripoli and many oil workers in remote desert areas.
