Mairi Chisholm (centre) with her friend Elsie Knocker in a communications trench on the Western Front during the First World War.
In 1914, 18-year-old Mairi Chisholm swapped the safety of her British home for the hazards of the Belgian front line.
When Mairi set off for London that year on her motor bike, her intention was to join the war effort as a dispatch rider.
Initially she signed up for the Women's Emergency Corps, before transferring to Dr Hector Munro's Flying Ambulance Corps.
Treating the wounded
Also working with Dr Munro was nurse Elsie Knocker, a friend of Mairi's and a fellow motor bike enthusiast.
The sense of adventure the two women shared led to them spending an incredible four years treating the wounded on the Western Front.
Mairi and Elsie set up a medical post in the cellar of a house in Pervyse.
Their bravery and the physical and spiritual benefits which they brought to the wounded would lead the Belgians to refer to them as the 'madonnas of Pervyse'.

Mairi's was one of the personal stories of the First World War that we told in our exhibition 'Behind the lines', which ran from 27 June to 11 November 2014.
