Hitler Line

In May 1944, the line was renamed the Senger Line, after General Fridolin von Senger und Etterlin, one of the generals commanding Axis forces in the area.

That was done at Adolf Hitler's insistence to minimise any propaganda significance if the line was penetrated.

The line was breached on 24 May 1944 on the British Eighth Army's front by the 1st Canadian Infantry Division and 5th Canadian Armoured Division, which attacked with II Polish Corps on their right.

The first to breach the line, at Pontecorvo were the 1st Canadian Division's 4th Princess Louise Dragoon Guards.

The Polish Corps captured Piedimonte on 25 May, and the line collapsed.
