Dragon's Teeth (fortification)
Dragon's teeth (german: Drachenzähne) are square-pyramidal fortifications of reinforced concrete first used during the Second World War to impede the movement of tanks and mechanised infantry. The idea was to slow down and channel tanks into killing zones where they could easily be disposed of by anti-tank weapons. They were employed extensively, particularly on the Siegfried Line. World War II Dragon's teeth were used by several armies in the European Theatre. The Germans made extensive use of them on the Siegfried Line and the Atlantic Wall. Typically, each tooth was tall. Land mines were often laid between teeth, and further obstacles were constructed along the lines of teeth, such as barbed wire to impede infantry or diagonally-placed steel beams to further hinder tanks. Many were laid in the United Kingdom in 1940–1941, as part of the effort to strengthen the country's defences against a possible German invasion. Due to the huge numbers laid and their durable ...

British Anti-invasion Preparations Of World War II
British anti-invasion preparations of the Second World War entailed a large-scale division of military and civilian mobilisation in response to the threat of invasion (Operation Sea Lion) by German armed forces in 1940 and 1941. The British Army needed to recover from the defeat of the British Expeditionary Force in France, and 1.5 million men were enrolled as part-time soldiers in the Home Guard. The rapid construction of field fortifications transformed much of the United Kingdom, especially southern England, into a prepared battlefield. Sea Lion was never taken beyond the preliminary assembly of forces. Today, little remains of Britain's anti-invasion preparations, although reinforced concrete structures such as pillboxes and anti-tank cubes can still be commonly found, particularly in the coastal counties. Political and military background On 1 September 1939, Germany invaded Poland; two days later, Britain and France declared war on Germany, launching the Second World ...

Toblerone
Toblerone ( , ) is a Swiss chocolate brand produced in Bern. Toblerone is known for its distinctive shape, a series of joined triangular prisms and lettering engraved in the chocolate. Since 2012, the brand has been owned by US company Mondelez International (successor of Kraft Foods Inc., which had acquired Toblerone from owner Jacobs Suchard in 1990). History The Tobler chocolate factory was founded in 1899 by Emil Baumann & Theodor Tobler (1876–1941) in Bern. In 1908, Emil Baumann, the cousin of Theodor Tobler, created the unique recipe consisting of milk chocolate including nougat, almonds, and honey. Theodor Tobler came up with the distinctive triangular shape and packaging. The product's name is a portmanteau combining Tobler's name with the Italian word '' torrone'' (a type of nougat). The triangular shape of the Matterhorn in the Swiss Alps/Italian Alps is commonly believed to have given Theodor Tobler his inspiration for the shape of Toblerone. However, accordi ...

Toblerone Line
The Toblerone line is a 10 km long defensive line made of " dragon's teeth" fortifications built during the Second World War between Bassins and Prangins, in the Canton of Vaud, Switzerland. These lines of defensive blocks can be found all over Switzerland, though more commonly in border areas. Their purpose was to stop tank invasions. The 2,700 9-ton concrete blocks that make up the defences are similar to the shape of the Toblerone chocolate bar, which gave its name to the line. Since the line has been left to nature since its construction, it was decided to keep these concrete blocks and to make a hiking trail along their route. The line was built along twelve fortresses, the most well known being the "Villa Rose" in Gland, which was transformed into a museum and opened to the public in 2006. History The Toblerone line is a part of the Promenthouse defence line, which more or less follows the watercourse of the brooklets Promenthouse and Serine. First reconnaissance ...

Rally Car
Rally is a wide-ranging form of motorsport with various competitive motoring elements such as speed tests (often called ''rally racing),'' navigation tests, or the ability to reach waypoints or a destination at a prescribed time or average speed. Rallies may be short in the form of trials at a single venue, or several thousand miles long in an extreme endurance rally. Depending on the format, rallies may be organised on private or public roads, open or closed to traffic, or off-road in the form of cross country or rally-raid. Competitors can use production vehicles which must be road-legal if being used on open roads or specially built competition vehicles suited to crossing specific terrain. Rallying is typically distinguished from other forms of motorsport by not running directly against other competitors over laps of a circuit, but instead in a point-to-point format in which participants leave at regular intervals from one or more start points.

Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the ''Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the beginning of the 18th century. An early well-documented case is that of the "two oak-posts" set up next to the medieval Eleanor cross at Waltham Cross, Hertfordshire, in 1721, at the expense of the Society of Antiqua ...

Alpine Wall
The Alpine Wall (''Vallo Alpino'') was an Italian system of fortifications along the of Italy's northern frontier. Built in the years leading up to World War II at the direction of Italian dictator Benito Mussolini, the defensive line faced France, Switzerland, Austria, and Yugoslavia. It was defended by the "Guardia alla Frontiera" (GaF), Italian special troops. Characteristics The Alpine line was similar in concept to other fortifications of the same era, including the Maginot Line of France, the Siegfried Line of Germany, and the National Redoubt of Switzerland. Italy's land frontiers were in most places mountainous and easily defended, but in the years leading up to World War II, Italy's relations with its neighbours were uneasy. Even in its dealings with its German ally, Italy was concerned about German ambitions towards the province of South Tyrol, inhabited by a German majority. Due to the rugged nature of the Alpine frontier, defences were confined to passes and obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
