This is a two stage multi. The posted coords will take you to the Memorial where you will need to collect some info and do some simple sums that will give you the coords to the second stage. When finding the second stage you will be able to obtain the coords to the final stage. This is where you can get your smiley face.
Starting with 1914-1918 war the number of men on this plaque will give you A B
The number of Privtes on this plaque will give you C
Moving on to the 1939-1945 war, the number of men on this plaque will give you D
The number of letters in the surname of the last name on this plaque will give you E
By now you should have all the info that you need to collect your coords to stage two!
Stage two can be found at: N 50 (B+A+A)(C-A).(E-A)(E-D-B)(B) W 003 (A)(E-D-B).(D+A)(E-B)(A-A)
