Page "River Mole" Paragraph 44

During the Second World War several sites along the course of the Mole were fortified to facilitate the defence of London against invasion from the south.

GHQ Line B ran along the North Downs from Farnham and Guildford, crossing the Mole Gap to the north of Dorking and following the river to Horley.

Between Betchworth and Box Hill, the north bank of the River Mole was stabilised and made steeper to prevent wheeled vehicles from crossing.

At Boxhill Farm, where access to the river from the north bank was required for the herd of dairy cows, a row of twelve concrete cylinders were cast as an anti-tank measure.

Gun mounts were also installed to protect both Boxhill and Deepdene bridges and several pillboxes were installed.

An anti-tank ditch was dug from the Stepping Stones eastwards across the fields belonging to Bradley Farm ( now Denbies vineyard ).
