While the British were trying to hold back the German advance, some thirty German tanks "swung over the foothills". The German tanks were advancing towards the site where Brigadier Charrington had located his headquarters. This was some three miles back from the British positions. There was a fierce fight that included German bombers attacking. 

The German advance was stopped by the Rangers and anti-tank gunners. They thought that they had knocked out as many as eight German tanks. British tanks also came into action and thought that they had knocked out five more German tanks. 

The armored brigad headquarters men came into action with their rifles and Bren guns. They were also with the New Zealand machine gunners who came into action. All this action happened at sunset. They had stopped the Germans but Brigadier Charrington decided to withdraw. 

British tanks and armored cars "covered the withdrawal". The tanks and armored cars were able to withdraw behind a smoke screen without a problem. The armored brigade was able to withdraw to Kozani and then drove down the mountain road to Grevena. 

By the time they came to Grevena, the armored brigade was very weak. Much of it was due to tanks breaking down. If you read Robert Crisp's book, Brazen Chariots, he writes about the poor mechanical condition of British tanks used in Greece. This is based on the account in "Greece Crete and Syria" by Gavin Long.
