Re: W/Cdr. H.S. Broughall
His M.C. was reported in the Bexhill-on-Sea Chronicle of September 30th 1916.
Flight Sub-Lieut Herbert S. Broughall, M.C, R.N reported missing in the Aberdeen Press & Journal of 25th September 1917. A family tree on ancestry.co.uk records that he was shot down over Germany after transferring to the R.N.A.S. and spent two years [sic] as a P.o.W.
He later appears in the newspapers in Ocotber 1930 in relation to a plane crash. The Nottingham Post of October 9th 1930 reported the crash of a 'Vickers bombing machine' at Martlesham, where he is described as 'Flight Lieutenant Herbert Seton Broughall, M.C, D.F.C.'

Later awarded Distinguished Flying Cross as per London Gazette dated 11 June 1924 "for distinguished service rendered during operations in Kurdistan between 15th February and 19th June 1923."
