Within a matter of weeks, the brigade, as part of the 2nd New Zealand Division, was in Greece and manning defences on the Aliakmon Line in preparation for the anticipated invasion of the country by the Germans. Following the invasion, Hargest's brigade mounted a spirited defence of its positions at Olympus Pass from 14 to 16 April before it had to withdraw to provide cover neighbouring New Zealand brigades conducting their own retreat. The brigade was eventually evacuated on the night of 24 April to Crete.
