The Battle of the Metaxas Line, also known in Greece as the Battle of the Forts, was the first battle during the German invasion of Greece in World War II. The Germans succeeded in capturing several individual forts but failed to breach the fortified Metaxas Line in general. The 2nd Panzer division with an enveloping move crossed the Yugoslavian borders, overcame Yugoslav and Greek resistance and captured Thessaloniki on the 9th of April. The capture of Thessaloniki forced the Greek East Macedonia Army Section to surrender on the 10th of April and the Metaxas Line battle was over. At the time, the Metaxas line was poorly manned, as most of the Greek Army was involved in the Greco-Italian War on the Albanian front.
