These incredible before and after photographs show how British and French soldiers had to have their faces completely rebuilt having been maimed during World War One.
The photos are part of a book, Faces from the Front, looking at the early development of plastic surgery. It highlights the work of young surgeon Harold Gillies, who repaired the faces of those who were injured and shipped back home between 1914 and 1918.
Mr Gillies spent years restoring the dignity of men who had been prepared to sacrifice their lives. His incredible skill saw him use a rib to reconstruct a jaw. He also spent six years and 19 operations restoring a cheek, upper lip and nose of another soldier.
