Vienna offensiveThe Vienna offensive was an offensive launched by the Soviet 2nd and 3rd Ukrainian Fronts in order to capture Vienna, Austria, during World War II. The offensive lasted from 16 March to 15 April 1945. After several days of street-to-street fighting, the Soviet troops captured the city. Vienna had been bombarded continuously for the year before the arrival of Soviet troops, and many buildings and facilities had been damaged and destroyed.
Allies of World War IIThe Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, the Empire of Japan, and the Kingdom of Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India.
Battle of BerlinThe 'Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin', was one of the last major offensives of the European theatre of World War II. After the Vistula–Oder offensive of January–February 1945, the Red Army had temporarily halted on a line east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.
OstravaOstrava (‘ostrava; Ostrawa, Ostrau ˈɔstʁaʊ) is a city in the north-east of the Czech Republic, and the capital of the Moravian-Silesian Region. It has about 280,000 inhabitants. It lies from the border with Poland, at the confluences of four rivers: Oder, Opava, Ostravice and Lučina. Ostrava is the third largest city in the Czech Republic in terms of both population and area, the second largest city in the region of Moravia, and the largest city in the historical land of Czech Silesia.
End of World War II in EuropeThe final battles of the European theatre of World War II continued after the definitive surrender of Nazi Germany to the Allies, signed by Field marshal Wilhelm Keitel on 8 May 1945 in Karlshorst, Berlin. After German leader Adolf Hitler's suicide and handing over of power to grand admiral Karl Dönitz in May 1945, Soviet troops conquered Berlin and accepted surrender of the Dönitz-led government.
European theatre of World War IIThe European theater of World War II was one of the two main theaters of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May.
German Instrument of SurrenderThe German Instrument of Surrender was a legal document effecting the unconditional surrender of the remaining German armed forces to the Allies, and ended World War II in Europe; the signing took place at 22:43 CET on 8 May 1945 and the surrender took effect at 23:01 CET on the same day. The day before that, Germany had signed another surrender document close to it with the Allies in Reims in France, but it was not recognized by the Soviet Union for enforcement, so another document was needed to sign; and in addition, immediately after signing the German forces were ordered to cease fire in the west and continue fighting in the east.
Waffen-SSThe Waffen-SS (ˈvafn̩ʔɛsˌʔɛs) (Armed SS) was the combat branch of the Nazi Party's paramilitary Schutzstaffel (SS) organisation. Its formations included men from Nazi Germany, along with volunteers and conscripts from both occupied and unoccupied lands. The Waffen-SS grew from three regiments to over 38 divisions during World War II, and served alongside the German Army (Heer), Ordnungspolizei (Order Police), and other security units.
