An attack was planed for the night by an Australian battalion that was to come from Georgioupolis. They were to travel 18 miles to fight. The Australians had not seen action during the first two days of the German attack on Crete, The Australians were the 80 men of the 2/7th Battalion. They had fought at Bardia. They were at Mersa Brega in February and March. They had been attacked from the air essentially every day. They had greater experience of German air attack tan any other unit in Crete.
Brigadier Vasey informed the battalion commander, Lt-Col. Walker that they were to "clear the road to Retimp. After that, they would helt the New Zealanders near Maleme. There was a meeting at Freyberg's headquarters where Brigadier Vasey was told of a new plan where the 2/7th Battalion was that night to relieve the 20th New ZEaland Battalion so that they could attack in the direction of Maleme. That left Vasey without any combat troops. He did have two battalions at Retimo, where they were cut off.
