Meanwhile, in Greece, the corps controlled the Australian 6th Division, the New Zealand 2nd Division, and the British 1st Armoured Brigade, as well as several ad hoc forces charged with the defence of northern Greece. On 12 April, it was officially renamed the Anzac Corps, a reference to the combined Australian-New Zealand formations of World War I. This was short-lived, though, as the Allied forces in Greece were quickly overcome by the German advance and after withdrawing from Gerania through Elasson, Larissa and Levadia, I Corps HQ left Greece on 23–24 April, and were subsequently evacuated to Egypt, although elements of the 6th Division were landed on Crete where they fought another short and unsuccessful campaign in May.
