Born in Farnham, Surrey, UK. Following a divorce from his birth father, his mother Hazel married his step-father, who adopted him and gave him the name Horsfall. A broken family life adversely affected his education, so he left school in 1972 at the age of fifteen and joined the army as a boy soldier.
Despite a long period of isolation and bullying by his peers, he became a full member of the Parachute Regiment in 1974 and served three tours of Northern Ireland. In 1978 he volunteered for SAS selection and passed on his second attempt in March 1979. He went on to qualify as a Paramedic and Sniper.
He was a member of the SAS counter terrorist team that assaulted the Iranian Embassy in London in 1980, helping to rescue the nineteen hostages who had been held for six days.
Robin has had an extraordinary life and has been speaking about it at events both small and large for over 10 years.
