Mouse Holing at Ortona

The Second World War Allied campaign in Italy is often called “an Engineer’s War” because of the terrain and obstacles the enemy created that had to be overcome. In December 1943, the German Army had retreated to the "Bernhard Line" across the narrowest part of the Italian Peninsula to halt or at least slow the Allied advance. The line crossed over mountain rivers swollen with winter rains that German military engineers reinforced by demolishing most of the bridges in the area to the south.
