Aspects of the event
In June 1944, the 504 battalion deployed for the first time south of Massa Marittima and briefly fought the invading Americans. They were then ordered to retreat 100km to a new defensive line. They spent the last few days of June driving north on secondary roads. A shocking one half of their Tigers broke down and had to be abandoned, mostly due to mechanical failure.
About 22 Tigers were lost in this retreat without enemy action.
