Elsie Knocker and Mairi Chisholm were possibly the two most famous women of the First World War.
They first met at a motorcycle rally in Bournemouth and raced in rallies and trials between 1912 and 1914. When war broke out they moved to London to "do their bit".
Within a week they were on the Western Front in Belgium, driving ambulances.
Frustrated by the numbers of men dying from shock in their ambulances, they set up their own First Aid Post a hundred yards from the Front, on the Ypres Sector. From that point, their fame spread, and eventually they were decorated with 17 medals for bravery and self sacrifice.
This is their story.
