One immediate problem was the lack of staffs. The New Zealand Division had Brigadier Puttick as commander. There was not good information about the units in Crete. The 14th Brigade with additional units of the "original garrison". There was the partial New Zealand Division. There were some Australian units withdrawn from Greece. There were also units from the 1st Armoured Brigade. There were some ten thousand mostly untrained new recruits from Crete.
The New Zealand Division in Crete had two brigades and seven infantry battalions. There were also some division soldiers. The 6th New Zealand Brigade had been transported from Suda Bay to Egypt.
There were some Australian units in Crete. The main unit was the18th Brigade fitted asa brigade group. There were 3-1/2 battalions in the brigade and a field regiment. More men arrived on destroyers. One Australian field regiment had been set with the4th New Zealand Brigade.
General Mackay and his staff seem to have been sent to Egypt. That meant that Brigadier Vaseywas the senior Australian officer in Crete. Brigadier Vasey had his brigade group and enough unorganized men for another brigade. This is based on the account in "Greece Crete and Syria" by Gavin Long.
