Wn's 18, 20, and 21 were waterfront positions in front of local buildings fronted with stakes, dragon's teeth, hedgehogs, barbed wire, minefields, mortar and "tobruk" pits. WN 18's 15.5 cm guns also had an anti tank ditch to it's rear.
WN's 12 14 16 and 17 were primarily underground positions behind the waterfront villages.
WN is the German abbreviation for Wiederstandneste, followed by thier numerical designation.
Casemated cuns were usually emplaced to fire laterally along the length of the beach with protection to the seaward side from naval gunfire. The entire beach was covered by machine guns with interlocking fields of fire for mutual support. The beach itself was fairly narrow with only a low rise of dunes or a seawall separating the inland terrain.
