In late May, VI Corps broke out of the Anzio beachhead in Operation Diadem with the 3rd Division in the main thrust. Instead of defeating the Germans, Lieutenant General Clark, the Fifth Army commander, disobeying orders from General Sir Harold Alexander, Commander-in-Chief (C-in-C) of the Allied Armies in Italy (formerly the 15th Army Group), sent the division on to the Italian capital of Rome. This allowed the majority of the German 10th Army, which would otherwise have been trapped, to escape, thus prolonging the campaign in Italy. The division was then removed from the front line and went into training for the Operation Dragoon, the Allied invasion of Southern France.
