Question: During WW2, when did the country where Halmyris is located join the allies?

full_context: Document 1: Halmyris: Halmyris was a Roman and Byzantine fort, settlement and naval port, located 2.5 kilometers west of the village of Murighiol at the mouth of the Danube Delta in Romania. It is locally known as the site where the bodies of two Christian saints, Epictet and Astion, were uncovered between 2001 and 2004.
Document 2: Josip Broz Tito: On 12 September 1944, King Peter II called on all Yugoslavs to come together under Tito's leadership and stated that those who did not were "traitors", by which time Tito was recognized by all Allied authorities (including the government-in-exile) as the Prime Minister of Yugoslavia, in addition to commander-in-chief of the Yugoslav forces. On 28 September 1944, the Telegraph Agency of the Soviet Union (TASS) reported that Tito signed an agreement with the Soviet Union allowing "temporary entry" of Soviet troops into Yugoslav territory which allowed the Red Army to assist in operations in the northeastern areas of Yugoslavia. With their strategic right flank secured by the Allied advance, the Partisans prepared and executed a massive general offensive which succeeded in breaking through German lines and forcing a retreat beyond Yugoslav borders. After the Partisan victory and the end of hostilities in Europe, all external forces were ordered off Yugoslav territory.
Document 3: Southampton: Archaeological finds suggest that the area has been inhabited since the stone age. Following the Roman invasion of Britain in AD 43 and the conquering of the local Britons in 70 AD the fortress settlement of Clausentum was established. It was an important trading port and defensive outpost of Winchester, at the site of modern Bitterne Manor. Clausentum was defended by a wall and two ditches and is thought to have contained a bath house. Clausentum was not abandoned until around 410.
Document 4: Constantin Sănătescu: Constantin Sănătescu (14 January 1885, Craiova – 8 November 1947, Bucharest) was a Romanian statesman who served as the 44th Prime Minister of Romania after the 23 August 1944 coup, through which Romania left the Axis Powers and joined the Allies.
Document 5: Warsaw: By July 1944, the Red Army was deep into Polish territory and pursuing the Germans toward Warsaw. Knowing that Stalin was hostile to the idea of an independent Poland, the Polish government-in-exile in London gave orders to the underground Home Army (AK) to try to seize control of Warsaw from the Germans before the Red Army arrived. Thus, on 1 August 1944, as the Red Army was nearing the city, the Warsaw Uprising began. The armed struggle, planned to last 48 hours, was partially successful, however it went on for 63 days. Eventually the Home Army fighters and civilians assisting them were forced to capitulate. They were transported to PoW camps in Germany, while the entire civilian population was expelled. Polish civilian deaths are estimated at between 150,000 and 200,000.
Document 6: Plymouth: Upper Palaeolithic deposits, including bones of Homo sapiens, have been found in local caves, and artefacts dating from the Bronze Age to the Middle Iron Age have been found at Mount Batten showing that it was one of the main trading ports of the country at that time. An unidentified settlement named 'TAMARI OSTIA' (mouth/estuaries of the Tamar) is listed in Ptolemy's Geographia and is presumed to be located in the area of the modern city.
Document 7: Romania in World War II: On 23 August 1944, with the Red Army penetrating German defenses during the Jassy -- Kishinev Offensive, King Michael I of Romania led a successful coup against the Axis with support from opposition politicians and most of the army. Michael I, who was initially considered to be not much more than a figurehead, was able to successfully depose the Antonescu dictatorship. The King then offered a non-confrontational retreat to German ambassador Manfred von Killinger. But the Germans considered the coup ``reversible ''and attempted to turn the situation around by military force. The Romanian First, Second (forming), and what little was left of the Third and the Fourth Armies (one corps) were under orders from the King to defend Romania against any German attacks. King Michael offered to put the Romanian Army, which at that point had a strength of nearly 1,000,000 men, on the side of the Allies. Surprisingly, with the Red Army occupying parts of Romania, Stalin immediately recognized the king and the restoration of the conservative Romanian monarchy. (Deutscher, Stalin. 1967, p. 519)
Document 8: Military saint: The Eastern Orthodox Church considers Demetrius of Thessaloniki, Theodore Stratelates, Theodore of Amasea, and John the Warrior to be the patron saints of the military. Saint Nicholas is the patron saint of the Russian navy; all naval cathedrals are dedicated to this saint. Finally Prophet Elijah is the patron Saint of the Hellenic Army Aviation Arm.
Document 9: Castra of Cristești: Although not unanimously accepted, the existence of the castra of Cristești in the Roman province of Dacia is substantiated by bricks and tiles bearing the name of a Roman military unit, the "Ala I Gallorum et Bosporanorum". The lack of any other traces of the Roman fort may easily be due to its destruction by the Mureș River. At Cristeşti, a Roman settlement from the 2nd and 3rd centuries AD was unearthed which was an important center of potters.
Document 10: Strasbourg: The centre of Argentoratum proper was situated on the Grande Île (Cardo: current Rue du Dôme, Decumanus: current Rue des Hallebardes). The outline of the Roman "castrum" is visible in the street pattern in the Grande Ile. Many Roman artifacts have also been found along the current Route des Romains, the road that led to Argentoratum, in the suburb of Kœnigshoffen. This was where the largest burial places were situated, as well as the densest concentration of civilian dwelling places and commerces next to the camp. Among the most outstanding finds in Kœnigshoffen were (found in 1911–12) the fragments of a grand Mithraeum that had been shattered by early Christians in the fourth century. From the fourth century, Strasbourg was the seat of the Bishopric of Strasbourg (made an Archbishopric in 1988). Archaeological excavations below the current Église Saint-Étienne in 1948 and 1956 unearthed the apse of a church dating back to the late fourth or early fifth century, considered to be the oldest church in Alsace. It is supposed that this was the first seat of the Roman Catholic Diocese of Strasbourg.
Document 11: Islam in Romania: Islam in Romania is followed by only 0.3 percent of population, but has 700 years of tradition in Northern Dobruja, a region on the Black Sea coast which was part of the Ottoman Empire for almost five centuries (ca. 1420-1878). In present-day Romania, most adherents to Islam belong to the Tatar and Turkish ethnic communities and follow the Sunni doctrine. The Islamic religion is one of the 16 rites awarded state recognition.
Document 12: Ukraine: German armies invaded the Soviet Union on 22 June 1941, initiating nearly four years of total war. The Axis initially advanced against desperate but unsuccessful efforts of the Red Army. In the encirclement battle of Kiev, the city was acclaimed as a "Hero City", because of its fierce resistance. More than 600,000 Soviet soldiers (or one-quarter of the Soviet Western Front) were killed or taken captive there, with many suffering severe mistreatment.Although the majority of Ukrainians fought in or alongside the Red Army and Soviet resistance, in Western Ukraine an independent Ukrainian Insurgent Army movement arose (UPA, 1942). Created as armed forces of the underground (Organization of Ukrainian Nationalists, OUN) which had developed in interwar Poland as a reactionary nationalist organization. During the interwar period, the Polish government's policies towards the Ukrainian minority were initially very accommodating, however by the late 1930s they became increasingly harsh due to civil unrest. Both organizations, OUN and UPA supported the goal of an independent Ukrainian state on the territory with a Ukrainian ethnic majority. Although this brought conflict with Nazi Germany, at times the Melnyk wing of the OUN allied with the Nazi forces. Also, UPA divisions carried out massacres of ethnic Poles, which brought reprisals. After the war, the UPA continued to fight the USSR until the 1950s. At the same time, the Ukrainian Liberation Army, another nationalist movement, fought alongside the Nazis.
Document 13: Operation Uranus: At 07:20 Moscow time on 19 November, Soviet forces on the northern flank of the Axis forces at Stalingrad began their offensive; forces in the south began on 20 November. Although Romanian units were able to repel the first attacks, by the end of 20 November the Third and Fourth Romanian armies were in headlong retreat, as the Red Army bypassed several German infantry divisions. German mobile reserves were not strong enough to parry the Soviet mechanized spearheads, while the Sixth Army did not react quickly enough nor decisively enough to disengage German armored forces in Stalingrad and reorient them to defeat the impending threat. By late 22 November Soviet forces linked up at the town of Kalach, encircling some 290,000 men east of the Don River. Instead of attempting to break out of the encirclement, German leader Adolf Hitler decided to keep Axis forces in Stalingrad and resupply them by air. In the meantime, Soviet and German commanders began to plan their next movements.
Document 14: Vladimir Stoychev: In 1944, Stoychev became a member of the Fatherland Front's Bureau of the National Committee. During World War II, Stoychev was in command of the Bulgarian First Army after the country switched allegiance to the Allies. Under Stoychev, the Bulgarian First Army helped the Red Army and Yugoslav Partisans drawing the Nazis out of much of Yugoslavia and Hungary, reaching the Austrian Alps by May 1945. On 8 May 1945, Vladimir Stoychev signed a demarkation agreement with British V Corps commander Charles Keightley in southern Austria. On 24 June 1945, he took part in the Moscow Victory Parade.
Document 15: Hagios Demetrios: The Church of Saint Demetrius, or Hagios Demetrios (), is the main sanctuary dedicated to Saint Demetrius, the patron saint of Thessaloniki (in Central Macedonia, Greece), dating from a time when it was the second largest city of the Byzantine Empire. It is part of the site Palaeochristian and Byzantine Monuments of Thessaloniki on the list of World Heritage Sites by UNESCO since 1988.
