Context: Borovitsy (also Borovitsi, Polotsk Northwest, and Borovtsy) is an air base in Belarus, located 16 km northwest of Polatsk. It is a Cold War air base with sprawling taxiway area and pads for about 40 aircraft. During the 1960s it was probably home to attack aircraft regiments, but by the 1980s it was served only by the 276 BVP (276th Combat Helicopter Regiment) flying Mi-8 and Mi-24 helicopters., The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed., Polotsk Airport (also Polotsk South) is an airport in Belarus, located 9 km south of Polotsk. It is purely civilian use., The French invasion of Russia, known in Russia as the Patriotic War of 1812 and in France as the Russian Campaign, began on 24 June 1812 when Napoleon's crossed the Neman River in an attempt to engage and defeat the Russian army. Napoleon hoped to compel Tsar Alexander I of Russia to cease trading with British merchants through proxies in an effort to pressure the United Kingdom to sue for peace. The official political aim of the campaign was to liberate Poland from the threat of Russia. Napoleon named the campaign the Second Polish War to gain favor with the Poles and provide a political pretext for his actions., The Second Battle of Polotsk (1820 October 1812) took place during Napoleon's invasion of Russia. In this encounter the Russians under General Peter Wittgenstein attacked and defeated a Franco-Bavarian force under Laurent Gouvion Saint-Cyr. In the aftermath of this success, the Russians took Polotsk and dismantled Napoleon's operations in Belarus. Wittgenstein's victory set the stage for the Battle of Berezina in November, in which three Russian armies converged on Napoleon from separate directions., Chashniki is a town in Vitebsk Region, Belarus, famous for the Battle of Czasniki that took place during the French Invasion of Russia (1812)., Napoleon Bonaparte ("Napoléon Bonaparte";  , born ""Napoleone di Buonaparte""; 15 August 1769  5 May 1821) was a French military and political leader who rose to prominence during the French Revolution and led several successful campaigns during the French Revolutionary Wars. As Napoleon I, he was Emperor of the French from 1804 until 1814, and again in 1815. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions in the Napoleonic Wars. He won most of these wars and the vast majority of his battles, building a large empire that ruled over continental Europe before its final collapse in 1815. One of the greatest commanders in history, his wars and campaigns are studied at military schools worldwide. Napoleon's political and cultural legacy has ensured his status as one of the most celebrated and controversial leaders in human history., Polotsk or Polatsk is a historical city in Belarus, situated on the Dvina River. It is the center of the Polatsk Raion in Vitebsk Voblast. Its population is more than 80,000 people. It is served by Polotsk Airport and during the Cold War was home to Borovitsy air base., The Napoleonic Wars (1803-1815) were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions, primarily led and financed by the United Kingdom. The wars resulted from the unresolved disputes associated with the French Revolution and the Revolutionary Wars, which had raged on for years before concluding with the Treaty of Amiens in 1802. The resumption of hostilities the following year paved the way for more than a decade of constant warfare often categorized into five conflicts: the War of the Third Coalition (1805), the War of the Fourth Coalition (1806-7), the War of the Fifth Coalition (1809), the War of the Sixth Coalition (1813), and the War of the Seventh Coalition (1815). The Napoleonic Wars had profound consequences for global and European history, leading to the spread of nationalism and liberalism, the rise of the British Empire as the world's premier power, the independence movements in Latin America and the collapse of the Spanish Empire, the fundamental reorganization of German and Italian territories into larger states, and the establishment of radically new methods in warfare. , Ludwig Adolph Peter, Prince Wittgenstein (Pyotr Khristianovich Vitgenshtein) (17 January (6 January) 1769 in Pereiaslav  11 June 1843 in Lemberg, Austrian Empire) was a Russian Field Marshal distinguished for his services in the Napoleonic wars., The Battle of Chashniki ( Russian :    , Belarusian :    ) , sometimes called the Battle of Czasniki ( from the Polish spelling - Polish : Czaniki ) , was fought during Napoleon 's invasion of Russia , on 31 October 1812 , between Russian forces under General Wittgenstein , and the French army , commanded by Marshal Victor . This battle was a failed effort by the French to reestablish their northern `` Dvina Line '' , which had crumbled as a result of Wittgenstein 's victory at the Second battle of Polotsk just two weeks earlier ., Vitebsk Region, Vitsebsk Voblast, or Vitebsk Oblast ("Viciebskaja Vobas") is a region (voblast) of Belarus with its administrative center being Vitebsk (Viciebsk). It is located near the border with Russia. , The French Revolutionary Wars were a series of sweeping military conflicts, lasting from 1792 until 1802, resulting from the French Revolution. They pitted the French First Republic against Britain, Austria and several other monarchies. They are divided in two periods: the War of the First Coalition (179297) and the War of the Second Coalition (17981802). Initially confined to Europe, the fighting gradually assumed a global dimension as the political ambitions of the Revolution expanded. After a decade of constant warfare and aggressive diplomacy, France had succeeded in seizing and conquering a wide array of territories, from the Italian Peninsula and the Low Countries in Europe to the Louisiana Territory in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe., Belarus ( lat. ', ), officially the Republic of Belarus, formerly known by its Russian name Byelorussia (though this name is no longer used in Belarus itself, even in Russian language), is a landlocked country in Eastern Europe bordered by Russia to the northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Its capital and most populous city is Minsk. Over 40% of its is forested. Its strongest economic sectors are service industries and manufacturing. Until the 20th century, different states at various times controlled the lands of modern-day Belarus, including the Principality of Polotsk (11th to 14th centuries), the Grand Duchy of Lithuania, the PolishLithuanian Commonwealth, and the Russian Empire., Emperor of the French (French: "Empereur des Français") was the title used by the House of Bonaparte starting when Napoleon Bonaparte was given the title Emperor on 14 May 1804 by the French Senate and was crowned emperor of the French on 2 December 1804 at the cathedral of Notre Dame de Paris, in Paris with the Crown of Napoleon., The French Revolution was a period of far-reaching social and political upheaval in France that lasted from 1789 until 1799, and was partially carried forward by Napoleon during the later expansion of the French Empire. The Revolution overthrew the monarchy, established a republic, experienced violent periods of political turmoil, and finally culminated in a dictatorship under Napoleon that rapidly brought many of its principles to Western Europe and beyond. Inspired by liberal and radical ideas, the Revolution profoundly altered the course of modern history, triggering the global decline of absolute monarchies while replacing them with republics and liberal democracies. Through the Revolutionary Wars, it unleashed a wave of global conflicts that extended from the Caribbean to the Middle East. Historians widely regard the Revolution as one of the most important events in human history., The Battle of Berezina (or Beresina) took place from 26 to 29 November 1812, between the French army of Napoleon, retreating after his invasion of Russia and crossing the Berezina (near Borisov, Belarus), and the Russian armies under Mikhail Kutuzov, Peter Wittgenstein and Admiral Pavel Chichagov. The battle ended with a mixed outcome. The French suffered very heavy losses but managed to cross the river and avoid being trapped. Since then ""Bérézina"" has been used in French as a synonym for "disaster.", Subject: battle of chashniki, Relation: part_of, Options: (A) 16 (B) 1960s (C) 1980s (D) 20th century (E) airport (F) august (G) belarus (H) british empire (I) building (J) center (K) city (L) country (M) crown (N) day (O) eastern europe (P) empire (Q) europe (R) french (S) french army (T) french invasion of russia (U) french revolution (V) french revolutionary wars (W) human (X) january (Y) june (Z) may ([) napoleonic wars (\) november (]) october (^) paris (_) population (`) river (a) russian (b) series (c) stage (d) the following (e) the republic (f) treaty (g) war (h) war of the first coalition (i) war of the fourth coalition (j) war of the second coalition (k) war of the sixth coalition (l) warfare (m) world war ii (n) year
