What was the name given to the line of German defences that ran across Italy from east to west, through the Apennine Mountains via the mountains behind the town of Cassino, to the mouth of the Sangro River in the east?
Winter Line Winter Line The Winter Line was a series of German and Italian military fortifications in Italy, constructed during World War II by Organisation Todt and commanded by Albert Kesselring. The series of 3 lines was designed to defend a western section of Italy, focused around the town of Monte Cassino, through which ran the important Highway 6 which led uninterrupted to Rome. The primary Gustav Line ran across Italy from just north of where the Garigliano River flows into the Tyrrhenian Sea in the west, through the Apennine Mountains to the mouth of the Sangro River on the Adriatic coast
Battle of Monte Cassino into the Pontine Marshes, which the Germans had flooded. Highway 6 ran through the Liri valley, dominated at its south entrance by the rugged mass of Monte Cassino above the town of Cassino. Excellent observation from the peaks of several hills allowed the German defenders to detect Allied movement and direct highly accurate artillery fire, preventing any northward advance. Running across the Allied line was the fast flowing Rapido River, which rose in the central Apennine Mountains, flowed through Cassino (joining to the Gari River, which was erroneously identified as the Rapido) and across the entrance to the Liri valley.
