In pictures: Faces of Battle

Traditionally, the edges of facial wounds were simply stitched together, but when scar tissue contracted faces were left twisted and disfigured.

Gillies did something different. He rebuilt faces using tissue from elsewhere in the body.

Today we think of breast implants and nose jobs, but plastic surgery had its birth in the wounded faces of veterans.

Dr Andrew Bamji, the Gillies archive curator, says: "He was prepared to try anything. He wouldn't give up."
