The situation deteriorates further in Greece

As events progressed on 14, 15, and 16 April 1941, the Germans were pressing forward. The mountainous terrain had made even communication difficult. One battalion of the 16th Australian Brigade found on 16 April 1941, that they should have withdrawn the night before. No one had been able to find them earlier, so that was not possible. By 14 April, General Wilson had ordered a withdrawal from the Aliakmon line. The Germans were using infiltration tactics to penetrate the New Zealand and Australian lines. They pretended to be retreating Greek troops to gain entrance to the positions. The New Zealanders recognized what was happening and opened fire with machine guns, doing dreadful execution on the Germans. They then rounded up many prisoners, some of them being Austrians. This is based on the account in Vol.II of the Australian Official History.
