Dr. Anthony Kollias immediately enlisted in the Greek Army, joining the medical corps. During the war, he was twice awarded Greece’s highest medal of valor, the Silver Cross, for his heroism on the front lines. Under German gunfire, he was able to pull a wounded superior to safety and exhibited uncommon bravery. In addition to this recognition, the Greek government awarded Dr. Kollias with a third medal of honor in 1949. His heroic actions led to his promotion in the field to a medical officer; however, he turned this down because he had not yet completed his medical studies and felt it was not right. Remarkably, Dr. Kollias also hid a Jewish family for months in the cellar of his rural home in Peloponessos during the German occupation.
