Königsberg Stadtplan 1905
Königsberg (, ) was the historic Prussian city that is now Kaliningrad, Russia. Königsberg was founded in 1255 on the site of the ancient Old Prussian settlement ''Twangste'' by the Teutonic Knights during the Northern Crusades, and was named in honour of King Ottokar II of Bohemia. A Baltic Sea, Baltic port city, it successively became the capital of the Królewiec Voivodeship, the State of the Teutonic Order, the Duchy of Prussia and the provinces of East Prussia and Province of Prussia, Prussia. Königsberg remained the coronation city of the Prussian monarchy, though the capital was moved to Berlin in 1701. Between the thirteenth and the twentieth centuries, the inhabitants spoke predominantly German language, German, but the multicultural city also had a profound influence upon the Lithuanian and Polish cultures. The city was a publishing center of Lutheran literature, including the first Polish translation of the New Testament, printed in the city in 1551, the first book ...

Frisches Haff
The Vistula Lagoon ( pl, Zalew Wiślany; russian: Калининградский залив, transliterated: ''Kaliningradskiy Zaliv''; german: Frisches Haff; lt, Aistmarės) is a brackish water lagoon on the Baltic Sea roughly 56 miles (90 km) long, 6 to 15 miles (10 to 19 km) wide, and up to 17 feet (5 m) deep, separated from the Gdańsk Bay by the Vistula Spit. The modern German name, ''Frisches Haff'', is derived from an earlier form, ''Friesisches Haff''.Erhard Riemann, Alfred Schoenfeldt, Ulrich Tolksdorf, Reinhard Goltz, Akademie der Wissenschaften und der Literatur (Germany), Akademie der Wissenschaften und der Literatur, Mainz, ''Preussisches Wörterbuch: Deutsche Mundarten Ost- und Westpreussens'', 6th edition, Wachholtz, 1974, p.595, Geography The lagoon is a mouth of a few branches of the Vistula River, notably Nogat and Szkarpawa, and of the Pregolya River.

Ludwig Yorck Von Wartenburg
Johann David Ludwig Graf Yorck von Wartenburg (born von Yorck; 26 September 1759 – 4 October 1830) was a Prussian ''Generalfeldmarschall'' instrumental in the switching of the Kingdom of Prussia from a French alliance to a Russian alliance during the War of the Sixth Coalition. Ludwig van Beethoven's "Yorckscher Marsch" is named in his honor. The Field Marshal's surname is Yorck; Wartenburg is a battle-honour appended to the surname as a title of distinction (cf. Britain's Montgomery of Alamein). Background Yorck's father, David Jonathan von Yorck, was born in Rowe in the Prussian Province of Pomerania (now Rowy, Poland), to Jan Jarka, a Lutheran pastor, whose family came from a small manor in Gross Gustkow (hence the name ''von Gostkowski'') and traced its origins from Pomeranian Kashubians. David Jonathan von Yorck served as a captain (''Hauptmann'') in the Prussian Army under King Frederick the Great; Yorck's mother Maria Sophia Pflug was the daughter of a Potsdam ...

Peter I Of Russia
Peter I ( – ), most commonly known as Peter the Great,) or Pyotr Alekséyevich ( rus, Пётр Алексе́евич, p=ˈpʲɵtr ɐlʲɪˈksʲejɪvʲɪtɕ, , group=pron was a Russian monarch who ruled the Tsardom of Russia from to 1721 and subsequently the Russian Empire until his death in 1725, jointly ruling with his elder half-brother, Ivan V until 1696. He is primarily credited with the modernisation of the country, transforming it into a European power. Through a number of successful wars, he captured ports at Azov and the Baltic Sea, laying the groundwork for the Imperial Russian Navy, ending uncontested Swedish supremacy in the Baltic and beginning the Tsardom's expansion into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lastin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seven Years' War
The Seven Years' War (1756–1763) was a global conflict that involved most of the European Great Powers, and was fought primarily in Europe, the Americas, and Asia-Pacific. Other concurrent conflicts include the French and Indian War (1754–1763), the Carnatic Wars and the Anglo-Spanish War (1762–1763). The opposing alliances were led by Great Britain and France respectively, both seeking to establish global pre-eminence at the expense of the other. Along with Spain, France fought Britain both in Europe and overseas with land-based armies and naval forces, while Britain's ally Prussia sought territorial expansion in Europe and consolidation of its power. Long-standing colonial rivalries pitting Britain against France and Spain in North America and the West Indies were fought on a grand scale with consequential results. Prussia sought greater influence in the German states, while Austria wanted to regain Silesia, captured by Prussia in the previous war, and to contain Pruss ...

Imperial Russian Army
The Imperial Russian Army (russian: Ру́сская импера́торская а́рмия, tr. ) was the armed land 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). Precursors: Regiments of the New Order Russian tsars before Peter the Great maintained professional hereditary musketeer corps known as '' streltsy''. These were originally raised by Ivan the Terrible; originally an effective force, they had become highly unreliable and undisciplined. In times of war the armed forces were augmented by peasants. The regiments of the new order, or regiments of the foreign order (''Полки нового строя'' or ''Полки иноземного строя'', ''Polki novovo (inozemnovo) stroya''), was the Russian term that was used to describe military units that were formed in the Tsardom of Russi ...

Counterscarp
A scarp and a counterscarp are the inner and outer sides, respectively, of a ditch or moat used in fortifications. Attackers (if they have not bridged the ditch) must descend the counterscarp and ascend the scarp. In permanent fortifications the scarp and counterscarp may be encased in stone. In less permanent fortifications, the counterscarp may be lined with paling fence set at an angle so as to give no cover to the attackers but to make advancing and retreating more difficult. If an attacker succeeds in breaching a wall a coupure can be dug on the inside of the wall to hinder the forlorn hope, in which case the side of the ditch farthest from the breached wall and closest to the centre of the fortification is also called the counterscarp. Counterscarp gallery These are tunnels or "galleries" that have been built behind the counterscarp wall inside the moat or ditch. Each gallery is pierced with loopholes for musketry, so that attacking forces that enter the moat can be dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covered Way
In military architecture, a covertway or covered way (french: chemin couvert it, strada coperta) is a path on top of the counterscarp of a fortification. It is protected by an embankment which is made up by the crest of the glacis. It is able to give the fort's garrison a position beyond the ditch, as well as a continuous line of communication around the outworks. An enlarged area within a covertway designed to allow troops to assemble on it is known as a place-of-arms A place-of-arms ( it, piazza d'armi, french: place d'armes) is any place in a fortification where troops can gather. The term has a number of meanings, but it generally refers to an enlarged area of the covertway designed as an assembly point fo .... References Fortification (architectural elements) {{fort-stub ...

Ravelin
A ravelin is a triangular fortification or detached outwork, located in front of the innerworks of a fortress (the curtain walls and bastions). Originally called a ''demi-lune'', after the ''lunette'', the ravelin is placed outside a castle and opposite a fortification curtain wall. The ravelin is the oldest and at the same time the most important outer work of the bastion fortification system. It originated from small forts that were supposed to cover the bridge that led across the moat to the city or fortress gate from a direct attack. From this original function, to protect the gate bridge, also comes its original Italian name "''rivellino''" (which means small bank work or with the German expression common for it: ''Brückenkopf'' – "bridge head"). Therefore, the ravelin was at first only a small work, which should only make the access to the bridge in front of the fortress gates more difficult. When it was realized in the 16th century that this would generally provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cavalier (fortification)
A cavalier is a fortification which is built within a larger fortification, and which is higher than the rest of the work. It usually consists of a raised platform within a fort or bastion, so as to be able to fire over the main parapet without interfering with the fire of the latter. Through the use of cavaliers, a greater volume of fire can be obtained, but its great height also makes it an easy target for a besieger's guns. There are two types of cavaliers: *Common cavalier – a raised gun platform without any additional defensive features *Defensible cavalier – a raised gun platform surrounded by a ditch. If the ditch cuts across the bastion's terreplein and is supported by cuts, the cavalier can also be considered as a retrenchment.

Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard conditions for temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) color diamond blue (bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby
A ruby is a pinkish red to blood-red colored gemstone, a variety of the mineral corundum ( aluminium oxide). Ruby is one of the most popular traditional jewelry gems and is very durable. Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, alongside amethyst, sapphire, emerald, and diamond. The word ''ruby'' comes from ''ruber'', Latin for red. The color of a ruby is due to the element chromium. Some gemstones that are popularly or historically called rubies, such as the Black Prince's Ruby in the British Imperial State Crown, are actually spinels. These were once known as "Balas rubies". The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of red, called blood-red or pigeon blood, commands a large premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
