The sign on this Memorial reads:-
No. 11 Fighter Group Royal Air Force Operations Room 1939 - 1946
Beneath this stone is the site of the underground Operations Room from which the greater part of the Hurricane & Spitfire Squadrons were controlled during the Battle of Britain
During this epic battle these squadrons shot down over 1,300 of the 1,733 enemy aircraft destroyed. This great achievement contributed largely to our ultimate success and survival and inspired Sir Winston Churchill's now famous words - "Never in the field of human conflict was so much owed by so many to so few."
