The main British unit on Crete in early May 1941 was the "fresh" 14th Brigade. They had been the Crete garrison at the time of the Greek operation. After the Greek fiasco, there were also four units built up from withdrawals from Greece: the "Rangers, Northumberland Hussars, 7th Medium Regiment, and 106th ROhal Horse Artillery". There were also men from the mobile naval base, coast artillery, anti-aircraft units, and base units.
There were also some ten thousand Greek troops, of which only three battalions were of any value. The other eight battalions were just recruits. The 5th (Cretan) division had fought in Albania and had been lost in the Greek collapse. General Freyberg had hoped to help organize the Greek troops on Crete, but there was the shortage of arms, equipment and leadership that hampered the effort. This is based on the account in Vol.II of the Australian Official History.
