In late May, the Allies broke out from the Monte Cassino and the Anzio regions as Operation Diadem bore fruit. On 23 May the 508th claimed 15 Shermans destroyed during a German counter-attack against advancing Allied forces near Cisterna, for the loss of a single Tiger. The next day they started to withdraw to Rome; two tanks were lost to mechanical failure, seven more were destroyed by their crews in Cori due to lack of fuel, eleven more near Giulianello from breakdown, and another one near Valmontone on 25 May. This was a total loss of twenty-two Tigers in three days, with only one from combat. The battalion commander, Major Hudel, was recalled to the Führer Headquarters and sacked.
