Evacuate Crete?

 The first step seemed to be to withdraw to Sfakia. The Greeks situation was difficult and their forces were at the point of disintegration. Wavell finally ordered Freyberg to evacuate his men  from Crete. They were not able to tell Colonel  not able to tell Colonel Campbell because they did not have ciphers at Retimo. Navy Lieutenant Haig was going to Retimo with ten tons of rations, Haig left without knowing about the order to withdraw from Crete. Freyberg was traveling to Sfakaia and didn't  know that Haig did not know about the evacuation order. Freyberg then asked the Cairo headquarters to dro a message to Campbell from an aircraft. 

The Germans were having  great deal of success on 26 and 27 May. the assault regiment had moved towithin two kilometers west of Canea. The 196th Mountain Regiment had captured Karatsos. From the Prison Valley, the 3rd Parachute Regiment had captured Perivolia. Still, the Germans were tired and had taken heavy losses. The 3rd Parachute Regiment had the strength of a weak battalion. During the day reinforcement landed at Maleme.
