Stützpunkt IXb H – Heeresküstenbatterie ‘Ongeren’

The ‘De Koog’ battery was initially located near beach marker 17 but its field of fire was deemed insufficiently broad and the battery did not perform well. Consequently, the Germans decided to move it to open terrain. As of late1944, Heeresküstenbatterie ‘De Koog’ was located near the hamlet of De Waal, east of the village of Den Burg. 
The battery consisted of six emplacements with 10.5-cm guns of Polish origin. Several farms in the area were confiscated and fortified into veritable farm bunkers, some of them having walls and roofs of more than 1.5 meters of compacted concrete.

The battery was never operational but it played an important role in the Georgian Uprising, in that it saw a lot of fighting in the night of 5-6 April 1945 and in the days thereafter. Many of the buildings suffered damage.
