ORP Wilk (1929)
ORP ''Wilk'' was the lead boat of her class of mine-laying submarines of the Polish Navy. The ship saw service in the Polish Navy from 1931 to 1951. Her name meant "Wolf" in Polish. History ''Wilk'' was laid down in 1927 at Chantiers et Ateliers Augustin Normand shipyard at Le Havre in France. Launched on April 12, 1929, she was commissioned into the Polish Navy on 31 October 1931.Twardowski, 1998 When World War II began on September 1, 1939, ''Wilk'', commanded by Captain Boguslaw Krawczyk, took part in the Worek Plan for the defence of the Polish coast, operating in Gdańsk Bay. On September 2 she spotted a destroyer ''Erich Steinbrinck'', but could not attack it, because she fell herself under attack by minesweepers (the German report on firing a torpedo at ''Steinbrinck'' is not confirmed by the Poles).Andrzej S.

Worek Plan
The Worek Plan (or ''Operation Worek'', pl, Plan Worek, literally ''Plan Sack'') was an operation of the Polish Navy in the first days of World War II, in which its five submarines formed a screen in order to prevent German naval forces from carrying out landings on the Polish coast, and to attack enemy ships bombarding Polish coastal fortifications, in particular the base on the Hel Peninsula. The operation came to naught, as the Germans did not have any plans for naval landings. It caused the submarines to operate in a confined area near the shore in shallow waters, making them vulnerable to strong enemy anti-submarine forces. As a result, despite making a number of attempts, the submarines were unable to directly sink any enemy ships during the operation, although a mine placed by the ''Żbik'' did sink a German minesweeper. No Polish submarines were lost to enemy action, but they suffered progressive wear and tear, and technical problems, forcing the submarine comma ...

Harwich
Harwich is a town in Essex, England, and one of the Haven ports on the North Sea coast. It is in the Tendring district. Nearby places include Felixstowe to the north-east, Ipswich to the north-west, Colchester to the south-west and Clacton-on-Sea to the south. It is the northernmost coastal town in Essex. Its position on the estuaries of the Stour and Orwell rivers, with its usefulness to mariners as the only safe anchorage between the Thames and the Humber, led to a long period of civil and military maritime significance. The town became a naval base in 1657 and was heavily fortified, with Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery. Harwich is the likely launch point of the ''Mayflower'', which carried English Puritans to North America, and is the presumed birthplace of ''Mayflower'' captain Christopher Jones. Harwich today is contiguous with Dovercourt and the two, along with Parkeston, are often referred to collectively as ''Harwich''. History The tow ...

Polish Government-in-exile
The Polish government-in-exile, officially known as the Government of the Republic of Poland in exile ( pl, Rząd Rzeczypospolitej Polskiej na uchodźstwie), was the government in exile of Poland formed in the aftermath of the Invasion of Poland of September 1939, and the subsequent occupation of Poland by Germany and the Soviet Union, which brought to an end the Second Polish Republic. Despite the occupation of Poland by hostile powers, the government-in-exile exerted considerable influence in Poland during World War II through the structures of the Polish Underground State and its military arm, the Armia Krajowa (Home Army) resistance. Abroad, under the authority of the government-in-exile, Polish military units that had escaped the occupation fought under their own commanders as part of Allied forces in Europe, Africa, and the Middle East. After the war, as the Polish territory came under the control of the communist Polish People's Republic, the government-in-exile rema ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buoy
A buoy () is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. Types Navigational buoys * Race course marker buoys are used for buoy racing, the most prevalent form of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are also used in underwater orienteering competitions. * Emergency wreck buoys provide a clear and unambiguous means of temporarily marking new wrecks, typically for the first 24–72 hours. They are coloured in an equal number of blue and yellow vertical stripes and fitted with an alternating blue and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the . * Ice marking buoys mark holes in frozen lakes and rivers so snowmobiles do not drive over the holes. * Large Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped with ...

Cross Of Valour (Poland)
The Cross of Valour ( pl, Krzyż Walecznych) is a Polish military decoration. It was first introduced by the Council of National Defense on 11 August 1920. It is awarded to an individual who "has demonstrated deeds of valour and courage on the field of battle." It may be awarded to the same person up to four times.The only soldier ever to receive more than 4 Crosses of Valour was Stefan Grot-Rowecki, commander of the Polish Home Army during World War II, who had reached his quota of 4 crosses during World War I and the Polish-Soviet War, yet was awarded 4 more crosses on 1 May 1943.

Kattegat
The Kattegat (; sv, Kattegatt ) is a sea area bounded by the Jutlandic peninsula in the west, the Danish Straits islands of Denmark and the Baltic Sea to the south and the provinces of Bohuslän, Västergötland, Halland and Skåne in Sweden in the east. The Baltic Sea drains into the Kattegat through the Danish Straits. The sea area is a continuation of the Skagerrak and may be seen as a bay of the North Sea, but in traditional Scandinavian usage, this is not the case. The Kattegat is a rather shallow sea and can be very difficult and dangerous to navigate because of the many sandy and stony reefs and tricky currents, which often shift. In modern times, artificial seabed channels have been dug, many reefs have been dredged by either sand pumping or stone fishing, and a well-developed light signaling network has been installed, to safeguard the very heavy international traffic of this small sea. There are several large cities and major ports in the Kattegat, including, in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Øresund
Øresund or Öresund (, ; da, Øresund ; sv, Öresund ), commonly known in English as the Sound, is a strait which forms the Danish–Swedish border, separating Zealand (Denmark) from Scania (Sweden). The strait has a length of ; its width varies from to . It is wide at its narrowest point between Helsingør in Denmark and Helsingborg in Sweden. Øresund, along with the Great Belt, the Little Belt and the Kiel Canal, is one of four waterways that connect the Baltic Sea to the Atlantic Ocean via Kattegat, Skagerrak, and the North Sea; this makes it one of the busiest waterways in the world. The Øresund Bridge, between the Danish capital Copenhagen and the Swedish city of Malmö, inaugurated on 1 July 2000, connects a bi-national metropolitan area with close to 4 million inhabitants. The HH Ferry route, between Helsingør, Denmark and Helsingborg, Sweden, in the northern part of Øresund, is one of the world's busiest international ferry routes, with more than 70 departures ...

Danish Straits
The Danish straits are the straits connecting the Baltic Sea to the North Sea through the Kattegat and Skagerrak. Historically, the Danish straits were internal waterways of Denmark; however, following territorial losses, Øresund and Fehmarn Belt are now shared with Sweden and Germany, while the Great Belt and the Little Belt have remained Danish territorial waters. The Copenhagen Convention of 1857 made all the Danish straits open to commercial shipping. The straits have generally been regarded as an international waterway. Toponymy and geography Five straits are named 'belt' (Danish: ''bælt''), the only ones in the world. Several other straits are named 'sound' (Danish, Swedish and German: ''sund''). Where an island is situated between a "belt" and a "sound", typically the broader strait is called "belt" and the narrower one is the "sound": * Als: ** separated from the continent by ''Alssund'' ** separated from Fyn by the southern part of the ''Little Belt'', an area refe ...
