Frequently attacked and continu- ally threatened by powerful neighbors, Greece has often found it exped- ient to resort to unconventional methods of warfare to defend or liber- ate its soil. Although examples of the employment of unconventional warfare can be cited fro many periods of Greek history, no period is of greater interest than the years 1941 to 1950. The history of Greece during World War II and the years immediately following, presents not only examples of guerrilla and counterguerrilla operations, but also clearly illustrates the result of failing to disarm and completely inactivate a guerrilla force at the conclusion of a war. During this brief period a complete cycle of a resistance movement can be traced: the organiza- tion of covert resistance, its development into overt guerrilla war- fare, guerrilla participation in the liberation of the nation, the attempt of the resistance organization to use its guerrilla force to seize the reins of government, the resulting civil war, and the even- tual downfall of the resistance movement. Since much of the Greek resistance movement was initiated or 1 dominated by the Greek Communist Party, the resistance cycle is also of interest in that it shows the standard techniques advocated by the Cominform for taking advantage of a critical situation to establish a Communistic form of government. The story of the fight to thwart Communist domination of Greece is of particular interest to students of United States military history since the accomplishment of the final phase of that fight -- the destruction of the Communist guerrilla forces -- came largely as a result of U.S. economic and military assistance. The Geography Greece occupies that lower extremity of the Balkan Peninsula which juts out into the Mediterranean from the main mass of eastern Europe. The mainland and the many island groups which form an integral part of Greece have an area of approximately 1,000 square miles, of which the islands represent a little less than one-fifth -- about 9,000 square miles. Mountains dominate the entire country, the most important range being the Pindus. An extension of the Balkans, the Pindus Range runs north and south through the western half of the peninsula as far south as the Bay of Corinth. Other smaller mountain groups, outcroppings of the Pindus Range, project into the eastern part of the peninsula and south into the Peloponnesus. The islands, too, are either mountainous or extremely hilly. The mountains of Greece are almost invariably rugged, rocky formations and, although some portions are heavily wooded, much of the mountain country has been almost completely deforested. 2 GREECE - A land of rugged mountains For the purposes of this study, mainland Greece can be convenient- ly divided into five principal areas which are historical as well as geographic entities. The Peloponnesus, the southern extension of the Greek peninsula, is connected to the rest of the mainland by the narrow Isthmus of Corinth, which is cut by the Corinth Canal. Like the balance of the country, the Peloponnesus is generally mountainous, although it has some coastal plains and a few level valleys scattered throughout the mountains. Central Greece is considered to be that portion extending from the Gulf of Corinth north to the Othrys Mountain Range, which runs east- ward from the Pindus Range to form the southern boundary of Thessaly. Athens, the capital and largest city of Greece, is located in the south- eastern corner of the central area. The long, narrow island of Euboea lies close and parallel to the eastern coast, generally considered as a part of central Greece. While Euboea and the mainland portion are both mountainous, there are some wide valleys and coastal plains. The third area, Thessaly, is a wedge-shaped sector, extending north from the Othrys Range to a line drawn generally from the vicinity of Metsovon northeast to the city of Katerini on the Gulf of Thermaikos on the east coast. The western part of Thessaly is extremely mountain- ous, but the eastern part contains two large basin areas. The fourth mainland area is composed of the district of Epirus, an almost entirely mountainous region which lies between Thessaly and the lonian Sea, and extends from the Gulf of Arta north to Albania. The fifth area is comprised of Macedonia and Greek Thrace. Western 3 Macedonia is almost entirely
