In August 2008 a massive military convoy set off across the desert in Helmand carrying a gigantic turbine for a hydro electric power station.

Monica Whitlock has been speaking to Joe Fossey, then a Major in the British Royal Engineers, who helped get the convoy through.Photo: Major Joe Fossey in Helmand Province. Courtesy of Major Fossey.
