Site of a Second World War light anti aircraft (Diver) battery south-west of Botolphs Bridge. This was armed with twelve 40mm guns, and was manned by 445 Battery of 135 Anti Aircraft Regiment when deployed on 2nd August 1944. It was redeployed to TR122328 on 2nd August 1944. It formed part of the Littlestone Section of 43 Anti Aircraft Brigade Light Anti Aircraft Artillery. The battery may be visible on aerial photographs taken in 1946, as suggested by cropmarks or parchmarks on the ground, though some of these may relate to the other Diver batterys (Monument Number 1477686 and 1477690) that were also located in this area. The cropmarks may relate to the location of the guns and ancillary buildings, but this is not clear.
