Would it be fair to describe that set up as unique, Mick?
Pretty much, I think, Tom. Mrs Knocker started out with the Munro Ambulance Corps based in Furnes, but became convinced that men were dying needlessly for want of treatment and stabilisation before being transported to hospital, so she set up her own forward dressing station at Pervyse. She was, if you like, freelance, but was supported by the Belgian Red Cross. She and Mairi Chisholm also worked with British wounded at various times and both were awarded the MM.
Their story is told in The Cellar House of Pervyse - http://www.greatward...ar_House_01.htm
and Flanders and Other Fields (by the Baroness de T'Serclaes, formerly Mrs Elsie Knocker).
Note in the online version of The Cellar House that the names accompanying the first photograph are the wrong way round. Mairi Chisholm is on the left and Elsie Knocker on the right.
Flanders and Other Fields is not yet available online as it was not published until 1964.
Forum searches on the women's names or Pervyse will bring up earlier discussions.
