The possible site of Second World War searchlight battery no. TG15 23 at Hambledon. In August 1941 35 Searchlight Regiment ordered its batteries to redeploy to the existing sites in area TG15 as part of the general declustering of lights and rearrangement into Indicator, Killer and GDA belts. The sites were redesignated as such, but no record of what type each became has been established. Searchlight sites typically comprised a small ring-ditch to provide the crew with shelter during an air raid, a predictor emplacement for calculating the height and range of targets, a light anti-aircraft machine gun pit, a generator and hutted accommodation for the crew.
