"The Hell of Rees"
In the autumn of 1944, the situation on the Western Front appeared increasingly threatening for the Nazi regime and the German army. After the Allied airborne landings near Eindhoven, Nijmegen, and Arnhem ("Operation Market Garden"), enemy troops had come very close to the German-Dutch border. Confronted with this situation, the Germans decided to strengthen their defensive positions in the Lower Rhine border region. Here, the so-called "Westwall" (also known as the „Siegfried Line“) consisted mainly of improvised earthworks rather than concrete bunkers, as was the case further south in the Eifel region and along the German-French border. In the Lower Rhine region further "entrenchment" works were now called for.
