Winston Churchill.

Hitler, though, said that of all the nations Germany fought, the Greeks were the bravest and most gallant, and out of admiration he ordered the release of all Greek POWs as soon as they were disarmed. Winston Churchill said, 'Hence we will not say that Greeks fight like heroes, but that heroes fight like Greeks.'

According to Hitler's Chief of Staff, Field Marshal Wilhelm Keitel, the Führer "wanted to give the Greeks an honorable settlement in recognition of their brave struggle, and of their blamelessness for this war: after all the Italians had started it." Inspired by the Greek resistance during the Italian and German invasions, Churchill said, "Hence we will not say that Greeks fight like heroes, but that heroes fight like Greeks". In response to a letter from George II dated December 3, 1940, American President Franklin D. Roosevelt stated that "all free peoples are deeply impressed by the courage and steadfastness of the Greek nation", and in a letter towards the Greek ambassador dated October 29, 1942, he wrote that "Greece has set the example which every one of us must follow until the despoilers of freedom everywhere have been brought to their just doom."
