Formerly a Lieutenant in the 3rd Volunteer Battalion of the Royal Fusiliers, he represented The Times in Spain during the rumours of an impending Carlist rising in 1898–99, and served as a Special War Correspondent for the Morning Post newspaper in South Africa, the same paper that also employed Winston Churchill, with the 3rd Division South African Field Force.
Cameron was a noted historian, novelist and verse-writer, and made numerous contributions to the Pall Mall Gazette, and many other publications of the period.
[3] He wrote a piece on the movement for The Albemarle, which was critical of the more political Legitimist Jacobite League of Great Britain and Ireland, but favourable towards the more artistic Order of White Rose.
Also involved with Cowethas Kelto Kernuak was Henry Jenner who later retired to Cornwall following a distinguished career as librarian at the British Museum.
The Cowethas Kelto Kernuak organisation petered out, when in 1903, Cameron left Cornwall to live at Boleskine near Loch Ness and the colourful and enigmatic Bardd Glas progressively turned his attention away from Cornish Celtic culture to Welsh.
