The impression taken away from Greece (in 1941)

The British and Commonwealth forces in Greece were not acclimatized to mountain combat. They face specialist German mountain troops, so they were at a disadvantage. As the political situation in Greece declined along with the military, the British were left with only one option: to withdraw. The Germans attacked at the "Monastir Gap", which was the junction between the Greek and British forces. Overhead, the Germans dominated the air. The collapse happened swiftly, so the British and Commonwealth forces had to rush to the south, to reach evacuation beaches. Somehow, they succeeded, and lost less than could have been expected. The Official History says that they left with the impression that they could beat the Germans, if they had the forces, despite the Germans being quite able and strong. This is my summary and paraphrase from the Official History.
