Clive Wilson Warman was born in the USA, 30th May 1892. He grew up to be a civil engineer but at the outbreak of World War One he appears to have signed up for the Canadian infantry (going on biographical information here as no records found to confirm this yet). After being wounded in France, he's transferred to a motor transport unit and spends time in Dublin. Again, biographical information suggests that he was there at the time of the Easter Rising. No information about what he did there but he would have been involved in the suppression in some form. Possibly the only American on the British side to take part?
He went back to England where he qualified as a pilot and joined the Royal Flying Corps. After a time as an instructor he was posted to France once more. Flying SPAD aircraft he appears to have claimed 12 enemy craft shot down and to have been awarded the DSO and Military Cross as well as a Mention in Dispatches.
After the war he remained in the Air Force (some books claim he was in the Canadian Air Force while his gravestone and CWGC entry shows Royal Air Force).
In May 1919 he died as a result of his aircraft crashing into the sewage farm in Edmonton, North London. One book states that he crashed in Edmonton, Canada but his death is registered in Edmonton, Middlesex, UK and he is buried in the UK.
Clive Warman is supposed to have enlisted with Princess Patricia's Regiment.No information about him on their excellent website. He does get a mention in a letter from Canadian flyer Norwood MacLeod to his father back in Canada.
