From 23 April to 25 April 1941

They heard that the Germans were now on Euboea on 23 April 1941. They sent reconnaissance aircraft to verify the story, but they did not see anyone. There were concerns about the 1/Rangers guarding the crossing at Khalkis. They needed to hold the crossing until the 6th Brigade could be south of there by the evening of the 25th. The 6th Brigade would leave a rearguard at Tatoi until they saw the Rangers withdraw through there.

Meanwhile, at Thermopylae, the British medium guns dueled with the German artillery. The troops were gradually withdrawing towards the beaches where they would withdraw. Some of the troops headed for the beaches at Marathon. An effort was made to post rearguards along the way that would move back in stages. There was some concern that the Germans might take the Delphi Pass, and cut off the line of retreat. The general state is reflected by the condition of the 4th Husssars, reduced to 12 light tanks, 6 carriers, and one armoured car by 23 April. This is based on the account in Vol.II of the Australian Official History.
