United States Marine Corps Aviation
–
United States Marine Corps Aviation is the air component of the United States Marine Corps. Marine aviation has a different mission and operation than its ground counterpart, and thus, has many of its own histories, traditions, terms. The Corps operates both rotary-wing and fixed-wing aircraft mainly to transport and close air support to its ground forces. However, other types are also used in a variety of support. Marine aviation officially began on 22 May 1912, when First Lieutenant Alfred Austell Cunningham reported to Naval Aviation Camp in Annapolis, Maryland, for duty in connection with aviation. On 20 August of that year, he became the first Marine aviator, as he took off in a Burgess Model H given to him by the Burgess Company in Marblehead Harbor in Marblehead, Massachusetts. In 1915, the Commandant of the Marine Corps authorized the creation of a Marine Corps aviation company consisting of 10 officers and 40 enlisted men. The first official Marine flying unit arrived with the 17 February 1917, the first major expansion of the Marine Corps air component came with Americas entrance into World War I in 1917. By the end of the war, several Marine Aviators had recorded air-to-air kills, the United States also embraced its role of global power and the Marine Corps became the preferred force for military intervention, where the Marines went, so went Marine aviation. It was in Haiti that Marines began to develop the tactic of dive bombing, while other nations and services had tried variations of this technique, Marine Aviators were the first to embrace it and make it part of their tactical doctrine. And besides dive-bombing Marine aviation in Nicaragua developed the skill of air resupply of outposts dropping bundles from Fokker F. VII tri-motors, also taking place during the 1920s was that Marine squadrons began qualifying on board aircraft carriers. Prior to this, Marine squadrons were loosely controlled with regard to doctrine and this assignment enabled nearly 60% of active duty aviators at the time to be exposed to a disciplined training syllabus under a clearly defined mission. The turning point for the survival of Marine Air came with the structural change of the establishment of the Fleet Marine Force in 1933. This shifted Marine doctrine to focus less on expeditionary duty and more on supporting amphibious warfare by seizing advance naval bases in the event of war. This organization would remain until June 1940 when Congress authorized the Marine Corps 1,167 aircraft as part of its 10,000 plane program for the Navy. On 7 December 1941, the day of the attack on Pearl Harbor, World War II would see the Marine Corps air arm expand rapidly and extensively. They would reach their peak number of units with 5 air wings,31 aircraft groups and 145 flying squadrons, during the war, and for the next fifty years, the Guadalcanal Campaign would become a defining point for Marine Aviation. Because of the way the Pacific War unfolded, Marine Aviation was not able to achieve its 1939 mission of supporting the Fleet Marine Force at first

Strategic bombing
–
One of the aims of war is to demoralize the enemy, so that peace or surrender becomes preferable to continuing the conflict. Strategic bombing has been used to this end, because the term has pejorative connotations, some, including the Allies of World War II, have preferred to use euphemisms such as will to resist and morale bombings. The theoretical distinction between tactical and strategic air warfare was developed between the two world wars, some leading theorists of strategic air warfare during this period were the Italian Giulio Douhet, the Trenchard school in the United Kingdom, and General Billy Mitchell in the United States. One of the aims of war is to demoralise the enemy, facing continual death, when such attacks were tried in the 1930s—in the Spanish Civil War and the Second Sino-Japanese War—they were ineffective. Commentators observed the failures and some air forces, such as the Luftwaffe, Terror bombing is an emotive term used for aerial attacks planned to weaken or break enemy morale. Use of the term to refer to aerial attacks implies the attacks are criminal according to the law of war, or if within the laws of war are nevertheless a moral crime. The Allied governments usually described their bombing of cities with other such as area bombing or precision bombing. He then added in a remark that the raid also helped destroy what is left of German morale. Howard Cowan, an Associated Press war correspondent, filed a story about the Dresden raid, there were followup newspaper editorials on the issue and a longtime opponent of strategic bombing, Richard Stokes, MP, asked questions in the House of Commons on 6 March. The first bombing of a city was on the night of 24–25 August 1914, the first effective strategic bombing was pioneered by the Royal Naval Air Service in 1914. The mission was to attack the Zeppelin production lines and their sheds at Cologne, led by Charles Rumney Samson the force of four aircraft inflicted minor damage on the sheds. The raid was repeated a month later with more success. Within a year or so, specialized aircraft and dedicated bomber squadrons were in service on both sides. These were generally used for bombing, the aim was that of directly harming enemy troops, strongpoints, or equipment. Eventually, attention turned to the possibility of causing harm to the enemy by systematically attacking vital rear-area resources. The most well known attacks were those done by Zeppelins over England through the course of the war, in all, four people were killed and sixteen injured, and monetary damage was estimated at £7,740. German airships also bombed on other fronts, for example in January 1915 on Liepāja in Latvia, in 1915 there were 19 more raids, in which 37 tons of bombs were dropped, killing 181 people and injuring 455. London was accidentally bombed in May, and in July the Kaiser allowed directed raids against urban centers, there were 23 airship raids in 1916, in which 125 tons of ordnance were dropped, killing 293 people and injuring 691

Imperial German Navy
–
The Imperial German Navy was the navy created at the time of the formation of the German Empire. It existed between 1871 and 1919, growing out of the small Prussian Navy, which primarily had the mission of coastal defence, Kaiser Wilhelm II greatly expanded the navy, and enlarged its mission. The key leader was Admiral Alfred von Tirpitz, who expanded the size and quality of the navy. The result was an arms race with Britain as the German navy grew to become one of the greatest maritime forces in the world. The German surface navy proved ineffective during World War I, its only major engagement, however, the submarine fleet was greatly expanded and posed a major threat to the British supply system. The Imperial Navys main ships were turned over to the Allies, all ships of the Imperial Navy were designated SMS, for Seiner Majestät Schiff. The Imperial Navy achieved some important operational feats, the Navy also emerged from the fleet action of the Battle of Jutland having destroyed more ships than it lost, although the strategic value of both of these encounters was minimal. The Imperial Navy was the first to operate successfully on a large scale in wartime, with 375 submarines commissioned by the end of the First World War. The unification of Germany under Prussian leadership was the point for the creation of the Imperial Navy in 1871. The newly created emperor, Wilhelm I, as King of Prussia, had previously been head of state of the strongest state forming part of the new empire, supreme command was vested in the emperor, but its first appointed chief was General der Infanterie Albrecht von Stosch. Kiel on the Baltic Sea and Wilhelmshaven on the North Sea served as the Navys principal naval bases, the former Navy Ministry became the Imperial Admiralty on 1 February 1872, while Stosch became formally an admiral in 1875. Initially the main task of the new Imperial Navy was coastal protection, with France, the Imperial Navys tasks were then to prevent any invasion force from landing and to protect coastal towns from possible bombardment. In March 1872 a German Imperial Naval Academy was created at Kiel for training officers, followed in May by the creation of a Machine Engineer Corps, in July 1879 a separate Torpedo Engineer Corps was created dealing with torpedoes and mines. In May 1872 a ten-year building programme was instituted to modernise the fleet, the building plan had to be approved by the Reichstag, which controlled the allocation of funds, although one-quarter of the money came from French war reparations. In 1883 Stosch was replaced by general, Count Leo von Caprivi. At this point the navy had seven armoured frigates and four armoured corvettes,400 officers and 5,000 ratings, in October 1887 the first torpedo division was created at Wilhelmshaven and the second torpedo division based at Kiel. In 1887 Caprivi requested the construction of ten armoured frigates, greater importance was placed at this time on development of the army, which was expected to be more important in any war. This shortened the journey for commercial ships, but specifically united the two areas principally of concern to the German navy, at a cost of 150 million marks, later, the protection of German maritime trade routes became important

U-boat
–
U-boat is the anglicised version of the German word U-Boot, a shortening of Unterseeboot, literally undersea boat. While the German term refers to any submarine, the English one refers specifically to military submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy warships, they were most effectively used in an economic warfare role. Austro-Hungarian navy submarines were known as U-boats. The first submarine built in Germany, the three-man Brandtaucher, sank to the bottom of Kiel harbor on 1 February 1851 during a test dive, the inventor and engineer Wilhelm Bauer had designed this vessel in 1850, and Schweffel & Howaldt constructed it in Kiel. Dredging operations in 1887 rediscovered Brandtaucher, it was raised and put on display in Germany, there followed in 1890 the boats WW1 and WW2, built to a Nordenfelt design. The SM U-1 was a completely redesigned Karp-class submarine and only one was built, the Imperial German Navy commissioned it on 14 December 1906. It had a hull, a Körting kerosene engine. The 50%-larger SM U-2 had two torpedo tubes, the U-19 class of 1912–13 saw the first diesel engine installed in a German navy boat. At the start of World War I in 1914, Germany had 48 submarines of 13 classes in service or under construction, during that war the Imperial German Navy used SM U-1 for training. Retired in 1919, it remains on display at the Deutsches Museum in Munich, on 5 September 1914, HMS Pathfinder was sunk by SM U-21, the first ship to have been sunk by a submarine using a self-propelled torpedo. On 22 September, U-9 sank the obsolete British warships HMS Aboukir, HMS Cressy, for the first few months of the war, U-boat anticommerce actions observed the prize rules of the time, which governed the treatment of enemy civilian ships and their occupants. On 20 October 1914, SM U-17 sank the first merchant ship, surface commerce raiders were proving to be ineffective, and on 4 February 1915, the Kaiser assented to the declaration of a war zone in the waters around the British Isles. This was cited as a retaliation for British minefields and shipping blockades, under the instructions given to U-boat captains, they could sink merchant ships, even potentially neutral ones, without warning. In February 1915, a submarine U-6 was rammed and both periscopes were destroyed off Beachy Head by the collier SS Thordis commanded by Captain John Bell RNR after firing a torpedo, on 7 May 1915, SM U-20 sank the liner RMS Lusitania. The sinking claimed 1,198 lives,128 of them American civilians, munitions that it carried were thousands of crates full of ammunition for rifles, 3-inch artillery shells, and also various other standard ammunition used by infantry. The sinking of the Lusitania was widely used as propaganda against the German Empire, a widespread reaction in the U. S was not seen until the sinking of the ferry SS Sussex. The sinking occurred in 1915 and the United States entered the war in 1917, the initial U. S. response was to threaten to sever diplomatic ties, which persuaded the Germans to issue the Sussex pledge that reimposed restrictions on U-boat activity

Belgium
–
Belgium, officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of 30,528 square kilometres and has a population of about 11 million people. Additionally, there is a group of German-speakers who live in the East Cantons located around the High Fens area. Historically, Belgium, the Netherlands and Luxembourg were known as the Low Countries, the region was called Belgica in Latin, after the Roman province of Gallia Belgica. From the end of the Middle Ages until the 17th century, today, Belgium is a federal constitutional monarchy with a parliamentary system of governance. It is divided into three regions and three communities, that exist next to each other and its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region is a bilingual enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia, Belgiums linguistic diversity and related political conflicts are reflected in its political history and complex system of governance, made up of six different governments. Upon its independence, declared in 1830, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. This continuing antagonism has led to several far-reaching reforms, resulting in a transition from a unitary to a federal arrangement during the period from 1970 to 1993. Belgium is also a member of the Eurozone, NATO, OECD and WTO. Its capital, Brussels, hosts several of the EUs official seats as well as the headquarters of major international organizations such as NATO. Belgium is also a part of the Schengen Area, Belgium is a developed country, with an advanced high-income economy and is categorized as very high in the Human Development Index. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings, a gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries, the Eighty Years War divided the Low Countries into the northern United Provinces and the Southern Netherlands. The latter were ruled successively by the Spanish and the Austrian Habsburgs and this was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815, although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 and for women in 1949. The main political parties of the 19th century were the Catholic Party, French was originally the single official language adopted by the nobility and the bourgeoisie

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Ostend
–
Ostend is a Belgian coastal city and municipality, located in the province of West Flanders. It comprises the boroughs of Mariakerke, Raversijde, Stene and Zandvoorde, in earlier times, Ostend was a small village built on the east-end of an island between the North Sea and a beach lake. Although small, the rose to the status of town around 1265 when the inhabitants were allowed to hold a market. The major source of income for the inhabitants was fishing, the North Sea coastline has always been rather unstable and in 1395 the inhabitants decided to build a new Ostend behind large dikes and further away from the always-threatening sea. The strategic position on the North Sea coast had major advantages for Ostend as a harbour, the town was frequently taken, ravaged, ransacked and destroyed by conquering armies. The Dutch rebels, the Gueuzen, took control of the town and this shocking event set in motion negotiations that led to a truce several years later. When the truce broke down, it became a Dunkirker base, after this era, Ostend was turned into a harbour of some importance. In 1722, the Dutch again closed off the entrance to the worlds biggest harbour of Antwerp, therefore, Ostend rose in importance because the town provided an alternative exit to the sea. The Belgium Austriacum had become part of the Austrian Empire, the Austrian Emperor Charles VI granted the town the trade monopoly with Africa and the Far-East. The Oostendse Compagnie was allowed to found colonies overseas, however, in 1727 the Oostendse Compagnie was forced to stop its activities because of Dutch and British pressure. The Netherlands and Britain would not allow competitors on the trade level. Both nations regarded international trade as their privilege, on 19 September 1826 the local artillery magazine exploded. At least 20 people were killed and a further 200 injured, the affluent quarter of dHargras was levelled and scarcely a building in the city escaped damage. Disease followed the leading to further deaths. The harbour of Ostend continued to expand because the harbour dock, in 1838, a railway connection with Brussels was constructed. Ostend became a harbour to England in 1846 when the first ferry sailed to Dover. Very important for the image of the town was the attention it started to receive from the Belgian kings Leopold I, both liked to spend their holidays in Ostend. Important monuments and villas were built to please the Royal Family, including the Hippodrome Wellington horse racing track, the rest of aristocratic Belgium followed and soon Ostend became known as The Queen of the Belgian sea-side resorts

Bruges
–
Bruges is the capital and largest city of the province of West Flanders in the Flemish Region of Belgium, in the northwest of the country. The area of the whole city amounts to more than 13,840 hectares, including 1,075 hectares off the coast, the historic city centre is a prominent World Heritage Site of UNESCO. It is oval and about 430 hectares in size, the citys total population is 117,073, of whom around 20,000 live in the city centre. The metropolitan area, including the commuter zone, covers an area of 616 km2 and has a total of 255,844 inhabitants as of 1 January 2008. Along with a few other canal-based northern cities, such as Amsterdam and Stockholm, Bruges has a significant economic importance thanks to its port and was once one of the worlds chief commercial cities. Bruges is well known as the seat of the College of Europe, the name probably derives from the Old Dutch for bridge, brugga. Also compare Middle Dutch brucge, brugge, and modern Dutch bruggehoofd, the form brugghe would be a southern Dutch variant. The Dutch word and the English bridge both derive from Proto-Germanic *brugjō-, Bruges was a location of coastal settlement during prehistory. This Bronze Age and Iron Age settlement is unrelated to medieval city development, in the Bruges area, the first fortifications were built after Julius Caesars conquest of the Menapii in the first century BC, to protect the coastal area against pirates. The Franks took over the region from the Gallo-Romans around the 4th century. The Viking incursions of the century prompted Count Baldwin I of Flanders to reinforce the Roman fortifications, trade soon resumed with England. Bruges received its city charter on 27 July 1128, and new walls and canals were built, in 1089 Bruges became the capital of the County of Flanders. Since about 1050, gradual silting had caused the city to lose its access to the sea. A storm in 1134, however, re-established this access, through the creation of a channel at the Zwin. The new sea arm stretched all the way to Damme, a city became the commercial outpost for Bruges. Bruges had a location at the crossroads of the northern Hanseatic League trade. They developed, or borrowed from Italy, new forms of merchant capitalism, whereby several merchants would share the risks and profits and they employed new forms of economic exchange, including bills of exchange and letters of credit. The city eagerly welcomed foreign traders, most notably the Portuguese traders selling pepper and other spices, the citys entrepreneurs reached out to make economic colonies of England and Scotlands wool-producing districts

Coastal submarine
–
A coastal submarine or littoral submarine is a small, maneuverable submarine with shallow draft well suited to navigation of coastal channels and harbors. Although size is not precisely defined, coastal submarines are larger than midget submarines, space limitations aboard coastal submarines restrict fuel availability for distant travel, food availability for extended patrol duration, and number of weapons carried. Within those limitations, however, coastal submarines may be able to reach areas inaccessible to larger submarines, improved versions of UB and UC coastal submarines were devised. The 30th U-boat Flotilla of six Type II U-boats was transported overland on the Autobahn, german Warships of the Second World War

English Channel
–
The English Channel, also called simply the Channel, is the body of water that separates southern England from northern France, and links the southern part of the North Sea to the Atlantic Ocean. It is about 560 km long and varies in width from 240 km at its widest to 33.3 km in the Strait of Dover and it is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2. The International Hydrographic Organization defines the limits of the English Channel as follows, a line joining Isle Vierge to Lands End. The southwestern limit of the North Sea, the IHO defines the southwestern limit of the North Sea as a line joining the Walde Lighthouse and Leathercoat Point. The Walde Lighthouse is 6 km east of Calais, and Leathercoat Point is at the end of St Margarets Bay. The Strait of Dover, at the Channels eastern end, is its narrowest point and it is relatively shallow, with an average depth of about 120 m at its widest part, reducing to a depth of about 45 m between Dover and Calais. Eastwards from there the adjoining North Sea reduces to about 26 m in the Broad Fourteens where it lies over the watershed of the land bridge between East Anglia and the Low Countries. It reaches a depth of 180 m in the submerged valley of Hurds Deep,48 km west-northwest of Guernsey. The eastern region along the French coast between Cherbourg and the mouth of the Seine river at Le Havre is frequently referred to as the Bay of the Seine. There are several islands in the Channel, the most notable being the Isle of Wight off the English coast. The coastline, particularly on the French shore, is indented, several small islands close to the coastline, including Chausey. The Cotentin Peninsula in France juts out into the Channel, whilst on the English side there is a parallel channel known as the Solent between the Isle of Wight and the mainland. The Celtic Sea is to the west of the Channel, the time difference of about six hours between high water at the eastern and western limits of the Channel is indicative of the tidal range being amplified further by resonance. It was never defined as a border and the names were more or less descriptive. It was not considered as the property of a nation, strangely, before the development of the modern nations, British scholars very often referred to it as Gaulish and the French one as British or English. The name English Channel has been used since the early 18th century. In modern Dutch, however, it is known as Het Kanaal, later, it has also been known as the British Channel or the British Sea having been called the Oceanus Britannicus by the 2nd-century geographer Ptolemy. The same name is used on an Italian map of about 1450, the Anglo-Saxon texts often call it Sūð-sǣ as opposed to Norð-sǣ

North Sea
–
The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and it is more than 970 kilometres long and 580 kilometres wide, with an area of around 570,000 square kilometres. The North Sea has long been the site of important European shipping lanes as well as a major fishery, the North Sea was the centre of the Vikings rise. Subsequently, the Hanseatic League, the Netherlands, and the British each sought to dominate the North Sea and thus the access to the markets, as Germanys only outlet to the ocean, the North Sea continued to be strategically important through both World Wars. The coast of the North Sea presents a diversity of geological and geographical features, in the north, deep fjords and sheer cliffs mark the Norwegian and Scottish coastlines, whereas in the south it consists primarily of sandy beaches and wide mudflats. Due to the population, heavy industrialization, and intense use of the sea and area surrounding it. In the southwest, beyond the Straits of Dover, the North Sea becomes the English Channel connecting to the Atlantic Ocean, in the east, it connects to the Baltic Sea via the Skagerrak and Kattegat, narrow straits that separate Denmark from Norway and Sweden respectively. In the north it is bordered by the Shetland Islands, and connects with the Norwegian Sea, the North Sea is more than 970 kilometres long and 580 kilometres wide, with an area of 570,000 square kilometres and a volume of 54,000 cubic kilometres. Around the edges of the North Sea are sizeable islands and archipelagos, including Shetland, Orkney, the North Sea receives freshwater from a number of European continental watersheds, as well as the British Isles. A large part of the European drainage basin empties into the North Sea including water from the Baltic Sea, the largest and most important rivers flowing into the North Sea are the Elbe and the Rhine – Meuse watershed. Around 185 million people live in the catchment area of the rivers discharging into the North Sea encompassing some highly industrialized areas, for the most part, the sea lies on the European continental shelf with a mean depth of 90 metres. The only exception is the Norwegian trench, which extends parallel to the Norwegian shoreline from Oslo to a north of Bergen. It is between 20 and 30 kilometres wide and has a depth of 725 metres. The Dogger Bank, a vast moraine, or accumulation of unconsolidated glacial debris and this feature has produced the finest fishing location of the North Sea. The Long Forties and the Broad Fourteens are large areas with uniform depth in fathoms. These great banks and others make the North Sea particularly hazardous to navigate, the Devils Hole lies 200 miles east of Dundee, Scotland. The feature is a series of trenches between 20 and 30 kilometres long,1 and 2 kilometres wide and up to 230 metres deep. Other areas which are less deep are Cleaver Bank, Fisher Bank, the International Hydrographic Organization defines the limits of the North Sea as follows, On the Southwest
