It was made by Commander (Actg. Capt.)* H. P. Douglas RN. His notes in the top left hand corner include the following:
'The contours are given for every 10 metres; and heights in metres and feet above sea level.......
Barbed wire entanglements were also placed in the shallow water off the beaches but had been removed when sketch was made.'
The full length of the linear scale shown is 1,000 yards and the sketch's scale is given as 1/9,000
* See post #6 for details of Douglas' promotions
The notation on the map itself is clear enough, except that is, for the word 'Gallows' shown above the northern end of V Beach, just to the right of the Ruined Barracks.
I have not noticed this before and wonder if anyone can offer an explanation.
