• An anti-personnel minefield was laid on the beach at Walberswick during the summer of 1940. Records suggest that it was approximately 400 metres in length, parallel to the sea, between the river and the main complex of anti-tank cubes; thus defending the direct approach to Walberswick itself.
  • Anti-personnel mines were detonated when a person steped on the mine. Mines were not intended to kill but to cause acute injury, as this would create maximum logistical difficulties for the enemy force in removing and treating their casualties.
