No title or production information on this sheet. There is a hand written Legend in the middle of the Adriatic Sea that presents a blue over gold wavy line and the words "Proposed Military Bdy (Morgan Line)". This appears to have been produced as part of Lieutenant General Sir William Duthie Morgan's negotiation with the Yugoslav leader Josip Broz Tito. The Morgan Line was the line of demarcation set up after World War II in the region known as Julian March which prior to the war belonged to the Kingdom of Italy. The Morgan Line was the border between two military administrations in the region: the Yugoslav on the east, and that of the Allied Military Government on the west. After 15 September 1947, the Allied Military Government was composed of both the British Element Trieste Forces (BETFOR) troops from the United Kingdom and the Trieste United States Troops (TRUST) from the United States. The Morgan Line established a temporary boundary between the Yugoslav and Allied administrations in the region of Julian March (Venezia Giulia), contended by Italy and the Socialist Federal Republic of Yugoslavia, and also to reduce the possibility of combat between Allied and Yugoslav forces in the area. The line was named after the British representative at the negotiations in Duino that resulted in the demarcation, Lieutenant General Sir William Duthie Morgan. Morgan, chief of staff to Field Marshal Sir Harold Alexander, Supreme Allied Commander in the Mediterranean, had been sent to Belgrade on May 7 to remind Yugoslav leader Josip Broz Tito that Yugoslav forces were in violation of a February 1945 written agreement between Tito and Alexander in occupying the territory. During the negotiations, Morgan drew up a line, then called the "Blue Line" and, when Allied troops of the British XIII Corps began moving forward to the blue line on May 22, Tito agreed in principle to the demarcation the next day, with the agreement signed in Duino on June 10, 1945. The line, approximately 70 miles in length, began on the coast just south of Trieste, curved 15 miles to the east and then northwest to Gorizia, Italy, then north along the Isonzo/So a River through Kobarid to Rate e near the Italian-Austrian border. The demarcation divided the Julian March into two zones, "Zone A" under Allied military administration and "Zone B" under the administration of the Yugoslav People's Army. Zone A comprised the western portion of the region, which included the current Italian provinces of Trieste and Gorizia, a strip of territory between the current Slovene-Italian border and the So a/Isonzo river, the Brda/Collio hills, the lower Vipava Valley/Valle del Vipacco (corresponding roughly to the current Slovene municipalities of Šempeter-Vrtojba, Ren e-Vogrsko, Miren-Kostanjevica and most of the municipality of Nova Gorica, except the Banjšice Plateau), the western section of the Karst Plateau (corresponding more or less to the current Slovene municipalities of Sežana and Komen), and the Istrian villages of Plavje, Spodnje Škofije, Elerji, and Hrvatini, now in Slovenia. The Istrian coastal town of Pula (now in Croatia) was also under Allied administration, forming an enclave of Zone A within the territory of Zone B. The Yugoslav-administered Zone B extended to almost two-thirds of the region, including the city of Rijeka/Fiume, most of the Istrian peninsula (with the exception of the town of Pula/Pola and the municipalities of Muggia and Dolina), the Cres-Lošinj/Cherso - Lussino archipelago, and the eastern portion of the Slovene Littoral. The village of Opatje Selo/ Oppachiesella on the northwestern edge of the Karst Plateau formed a small enclave of Zone B within the territory of Zone A. The Morgan Line ceased to exist on 15 September 1947, when the Treaty of Peace with Italy came into effect. Condition: Good.
