Please answer the following question: Information:  - Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism.  - Romania is a sovereign state located in Southeastern Europe. It borders the Black Sea, Bulgaria, Ukraine, Hungary, Serbia, and Moldova. It has an area of and a temperate-continental climate. With 19.94 million inhabitants, the country is the seventh-most-populous member state of the European Union. The capital and largest city, Bucharest, with its 1,883,425 inhabitants is the sixth-largest city in the EU.  - The Territory of the Military Commander in Serbia was the area of the Kingdom of Yugoslavia that was placed under a military government of occupation by the Wehrmacht following the invasion, occupation and dismantling of Yugoslavia in April 1941. The territory included Serbia proper, with the addition of the northern part of Kosovo (around Kosovska Mitrovica), and the Banat. This territory was the only area of partitioned Yugoslavia in which the German occupants established a military government. This was due to the key rail and riverine transport routes that passed through it, and its valuable resources, particularly non-ferrous metals. On 22 April 1941, the territory was placed under the supreme authority of the German military commander in Serbia, with the day-to-day administration of the territory under the control of the chief of the military administration staff. The lines of command and control in the occupied territory were never unified, and were made more complex by the appointment of direct representatives of senior Nazi figures such as "Reichsführer-SS" Heinrich Himmler (for police and security matters), "Reichsmarschall" Hermann Göring (for the economy), and "Reichsminister" Joachim von Ribbentrop (for foreign affairs). The Germans used Bulgarian troops to assist in the occupation, but they were at all times under German control. Sources variously describe the territory as a puppet state, a protectorate, a "special administrative province", or describe it as having a puppet government. The military commander in Serbia had very limited German garrison troops and police detachments to maintain order, but could request assistance from a corps of three divisions of poorly-equipped occupation troops.  - The Russian Corps was an armed force composed of anti-Communist Russian émigrés in the Territory of the Military Commander in Serbia during World War II. Commanded by Lieutenant-General Boris Shteifon, it served primarily as a guard force from the autumn of 1941 until the spring of 1944. It was incorporated into the Wehrmacht on 1 December 1942 and later clashed with both the Yugoslav Partisans and the Chetniks. In late 1944 it fought against the Red Army during the Belgrade Offensive, later withdrawing to Bosnia and Slovenia when the Germans withdrew from the Balkans. Shteifon was killed in April 1945 and was replaced by Colonel Anatoly Rogozhin, who subsequently managed to evade the Communists by surrendering to the British instead. He and his men were eventually set free and were allowed to resettle in the West.  - World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.  - Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15 a.m. on August 6, 1945, near the end of World War II.  - The Wehrmacht (lit. "defence force") was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the "Heer" (army), the "Kriegsmarine" (navy) and the "Luftwaffe" (air force). The designation "Wehrmacht" for Nazi Germany's military replaced the previously used term, "Reichswehr" (191935), and was the manifestation of Nazi Germany's efforts to rearm the nation to a greater extent than the Treaty of Versailles permitted.  - Serbia, officially the Republic of Serbia, is a sovereign state situated at the crossroads of Central and Southeast Europe, covering the southern part of the Pannonian Plain and the central Balkans. Relative to its small territory, it is a diverse country distinguished by a "transitional" character, situated along cultural, geographic, climatic and other boundaries. Serbia is landlocked and borders Hungary to the north; Romania and Bulgaria to the east; Macedonia to the south; and Croatia, Bosnia-Herzegovina, and Montenegro to the southwest; it also claims a border with Albania through the disputed territory of Kosovo. Serbia numbers around 7 million residents, and its capital, Belgrade, ranks among the largest cities in Southeast Europe.  - Hungary is a unitary parliamentary republic in Central Europe. It covers an area of , situated in the Carpathian Basin and bordered by Slovakia to the north, Romania to the east, Serbia to the south, Croatia to the southwest, Slovenia to the west, Austria to the northwest, and Ukraine to the northeast. With about 10 million inhabitants, Hungary is a medium-sized member state of the European Union. The official language is Hungarian, which is the most widely spoken Uralic language in the world. Hungary's capital and largest metropolis is Budapest, a significant economic hub, classified as an Alpha- global city. Major urban areas include Debrecen, Szeged, Miskolc, Pécs and Gyr.  - Belgrade is the capital and largest city of Serbia. It is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. Its name translates to "White city". The urban area of the City of Belgrade has a population of 1.34 million, while over 1.65 million people live within its administrative limits.  - Albania (; ), officially the Republic of Albania, is a sovereign state in Southeastern Europe. It has a population of 3.03 million as of 2016. Tirana is the nation's capital and largest city, followed by Durrës and Vlorë. Albania is located in the south-western part of the Balkan peninsula, bordered by Montenegro to the northwest, Kosovo to the northeast, the Republic of Macedonia to the east, and Greece to the south and southeast. The country has a coastline on the northern shore of the Mediterranean Sea, the Adriatic Sea to the west and the Ionian Sea to the southwest where the Albanian Riviera begins. Albania is less than from Italy, across the Strait of Otranto which connects the Adriatic Sea to the Ionian Sea.  - The Holocaust (from the Greek ': "hólos", "whole" and "kaustós", "burnt"), also referred to as the Shoah"' (Hebrew: , "HaShoah", "the catastrophe"), was a genocide in which Adolf Hitler's Nazi Germany and its collaborators killed about six million Jews. The victims included 1.5 million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany.  - Boris Aleksandrovich Shteifon (6 December 1881  30 April 1945) was a general in the Imperial Russian Army, who subsequently served as a general in the Russian anti-communist White army, and as the leader of the Nazi-allied Russian Corps in Serbia during World War II.  - The Belgrade Offensive or the Belgrade Strategic Offensive Operation ( ) (14 September 1944  24 November 1944) was a military operation in which Belgrade was liberated from the German Wehrmacht through the joint efforts of the Soviet Red Army, Yugoslav Partisans, and the Bulgarian People's Army. Soviet forces and local militias launched separate but loosely cooperative operations that undermined German control of Belgrade and ultimately forced a retreat. Martial planning was coordinated evenly among command leaders, and the operation was largely enabled through tactical cooperation between Josip Tito and Joseph Stalin that began in September 1944. These martial provisions allowed Bulgarian forces to engage in operations throughout Yugoslav territory, which furthered tactical success while increasing diplomatic friction.   - The Workers' and Peasants' Red Army (: RKKA, frequently shortened in Russian to ; KA, in English: Red Army also in critical literature and folklore of that epoch - Red Horde, Army of Work) was the army and the air force of the Russian Soviet Federative Socialist Republic, and after 1922 the Union of Soviet Socialist Republics. The army was established immediately after the 1917 October Revolution (Red October or Bolshevik Revolution). The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Beginning in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in December 1991.  - Russia, also officially known as the Russian Empire, was a state that existed from 1721 until it was overthrown by the short-lived liberal February Revolution in 1917. One of the largest empires in world history, stretching over three continents, the Russian Empire was surpassed in landmass only by the British and Mongol empires. The rise of the Russian Empire happened in association with the decline of neighboring rival powers: the Swedish Empire, the PolishLithuanian Commonwealth, Persia and the Ottoman Empire. It played a major role in 181214 in defeating Napoleon's ambitions to control Europe, and expanded to the west and south.  - The Imperial Russian Army was the land armed force of the Russian Empire, active from around 1721 to the Russian Revolution of 1917. In the early 1850s, the Russian army consisted of more than 900,000 regular soldiers and nearly 250,000 irregulars (mostly Cossacks).  - Kosovo  is a disputed territory and partially recognised state in Southeast Europe that declared independence from Serbia in February 2008 as the Republic of Kosovo. Kosovo is landlocked in the central Balkan Peninsula. Its capital and largest city is Pristina. It is bordered by the Republic of Macedonia and Albania to the south, Montenegro to the west, and the uncontested territory of Serbia to the north and east. While Serbia recognises administration of the territory by Kosovo's elected government, it still continues to claim it as its own Autonomous Province of Kosovo and Metohija.  - Boris Aleksandrovich Shteifon ( December 6 , 1881 -- April 30 , 1945 ) ( Russian :    ) was a general in the Imperial Russian Army , who subsequently served as a general in the Russian anti-communist White army , and as the leader of the Nazi - allied Russian Corps in Serbia during World War II.  - The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.
