Duitse verdedigingswerken (o.a. langs de kust - Atlantikwall). Emanating from neutral sources show the systematic flooding of large areas of Holland by the Germans. Land which has been drained and cultivated by the Dutch over a period of centuries, has now been ruined for years to come by sea-water. Villages and fields are completely submerged and the fertile soil has become a quagmire broken only by gun emplacement and pill boxes. Anti-tank defences built by the Germans along the coast of Holland.
