On 20 April 1941, the last 15 Hurricanes in Greece took off and intercepted a German attacking force consisting of 100 divebombers and fighters. The British had 22 certain kills and 8 more probables. The British losses were five Hurricanes. During the night, General Wavell visited General Blamey's ANZAC Corps headquarters and ordered him to withdraw as soon as possible. The troops needed to reach the embarkation beaches on 24 April to be evacuated that night. The ANZAC Corps were mostly on the road with rearguard detachments protecting the retreat. The column on the road from Larisa to Lamia was attacked from the air in the morning. The senior officers were involved in the retreat and made sure that the men saw them along the roads. This is based on the account in Vol.II of the Australian Official History.
