Underwood selected a dead willow tree in no man's land between trenches, and sketched it. [3] His sketches were used to build a replica that incorporated a steel-armoured observation tower and a periscope to protect the user. [3] [6] One night in March 1916, the original tree was cut down and replaced with the camouflaged tree. [3]
