Laura Clouting, a historian at The Imperial War Museum, has told Forces Network about 'Douglas', who made up one small part of the weird and wonderful forms of entertainment available to British troops during the First World War.
Douglas was used by ventriloquist Arthur Langley Harden, who served with the Royal Artillery during the First World War, to entertain fellow troops. The hole in this case was made by shrapnel from a German artillery shell.
Harden, who was apparently attached to a colonel's staff, said: "I reckon that doll saved my life - the colonel enjoyed him so much that he prevented my posting elsewhere and mildly discouraged me from taking the offer of going for a commission."
The dummy was possibly named after Field Marshal Sir Douglas Haig, the British Commander-in-Chief.
