The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II, fought in the Pacific and Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, in China; the Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more accepted that the Pacific War itself began on 7/8 December 1941, when Japan invaded Thailand and attacked the British colonies of Malaya and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island and the Philippines; the Pacific War saw the Allies pitted against Japan, the latter aided by Thailand and to a much lesser extent by the Axis allied Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, other large aerial bomb attacks by the Allies, accompanied by the Soviet declaration of war and invasion of Manchuria on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945.
The formal surrender of Japan ceremony took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. After the war, Japan lost all rights and titles to its former possessions in Asia and the Pacific, its sovereignty was limited to the four main home islands. Japan's Shinto Emperor was forced to relinquish much of his authority and his divine status through the Shinto Directive in order to pave the way for extensive cultural and political reforms. In Allied countries during the war, the "Pacific War" was not distinguished from World War II in general, or was known as the War against Japan. In the United States, the term Pacific Theater was used, although this was a misnomer in relation to the Allied campaign in Burma, the war in China and other activities within the Southeast Asian Theater. However, the US Armed Forces considered the China-Burma-India Theater to be distinct from the Asiatic-Pacific Theater during the conflict. Japan used the name Greater East Asia War, as chosen by a cabinet decision on 10 December 1941, to refer to both the war with the Western Allies and the ongoing war in China.
This name was released to the public on 12 December, with an explanation that it involved Asian nations achieving their independence from the Western powers through armed forces of the Greater East Asia Co-Prosperity Sphere. Japanese officials integrated what they called the Japan–China Incident into the Greater East Asia War. During the Allied military occupation of Japan, these Japanese terms were prohibited in official documents, although their informal usage continued, the war became known as the Pacific War. In Japan, the Fifteen Years' War is used, referring to the period from the Mukden Incident of 1931 through 1945; the Axis states which assisted Japan included the authoritarian government of Thailand, which formed a cautious alliance with the Japanese in 1941, when Japanese forces issued the government with an ultimatum following the Japanese invasion of Thailand. The leader of Thailand, Plaek Phibunsongkhram, became enthusiastic about the alliance after decisive Japanese victories in the Malayan Campaign and in 1942 sent the Phayap Army to assist the invasion of Burma, were former Thai territory, annexed by Britain were reoccupied.
The allies supported and organized an underground anti-Japanese resistance group, known as the Free Thai Movement, after the Thai ambassador to the United States had refused to hand over the declaration of war. Because of this, after the surrender in 1945, the stance of the United States was that Thailand should be treated as a puppet of Japan and be considered an occupied nation rather than as an ally; this was done in contrast to the British stance towards Thailand, who had faced them in combat as they invaded British territory, the United States had to block British efforts to impose a punitive peace. Involved were members of the Greater East Asia Co-Prosperity Sphere, which included the armies of the Japanese puppet states of Manchukuo, the collaborationist Wang Jingwei regime. In the Burma Campaign, other members, such as the anti-Britsh Indian National Army of Free India and Burma National Army of the State of Burma were active and fighting alongside their Japanese allies. Moreover, Japan conscripted many soldiers from its colonies of Taiwan.
Collaborationist security units were formed in Hong Kong, the Philippines, Dutch East Indies, British Malaya, British Borneo, former French Indochina as well as Timorese militia. These units the assisted Japanese war effort in their respective territories. Germany and Italy both had limited involvement in the Pacific War; the German and the Italian navies operated submarines and raiding ships in the Indian and Pacific Oceans. The Italians had access to concession territory naval bases in China. After Japan's attack on Pearl Harbor and the subsequent declarations of war, both navies had access to Japanese naval facilities; the major Allied participants were the United States and their colonies, the Republic of China, engaged in bloody war against Japan since 1937, the United Kingdom (mos
A sight is an aiming device used to assist in visually aligning ranged weapons, surveying instruments or optical illumination equipments with the intended target. Sights can be a simple set or system of markers that have to be aligned together with the target, or optical devices that allow the user to see a sometimes optically enhanced image of the target aligned in the same focus with an aiming point. There are sights that project an aiming point onto the target itself, such as laser sights and infrared illuminators on some night vision devices. At its simplest, a sight has two components and rear aiming pieces that have to be lined up. Sights such as this can be found on many types of devices including weapons and measuring instruments, navigational tools. On weapons, these sights are formed by rugged metal parts, giving them the name "iron sights", as distinct from optical or computing sights. On many types of weapons they are built-in and may be fixed, adjustable, or marked for elevation, target speed, etc.
They are classified in forms of notch or aperture. These types of sights can require considerable experience and skill, as the user has to hold proper eye position and focus on the rear sight, the front sight, a target, all at different distances, align all three planes of focus. Optical sights use optics that give the user an image of an aligned aiming point or pattern superimposed at the same focus as the target. A telescopic sight is an optical telescope equipped with some form of graphic image pattern reticle mounted in an optically appropriate position in the optical system to give an accurate aiming point. Telescopic sights are used on a wide range of devices including guns, surveying equipment, as sights on larger telescopes. Another type of optical sight is the reflector sight, a non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view; these sights have been around for over 100 years and have been used on all types of weapons and devices.
Reflector sights were first used as a weapon sight in German aircraft towards the end of World War I. Over the years they became more sophisticated, adding lead computing gyroscopes and electronics radar range finding and other flight information in the 1950s and 60s becoming the modern head-up display. Collimator sight Holographic weapon sight Laser sight There are many types of sighting devices, they can be fixed, optical, computational, or a mixture of all of these attributes.

A torpedo tube is a cylinder shaped device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, deck-mounted units installed aboard surface vessels. Deck-mounted torpedo launchers are designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, are also capable of deploying mines and cruise missiles. Most modern launchers are standardised on a 12.75-inch diameter for light torpedoes or a 21-inch diameter for heavy torpedoes, although other sizes of torpedo tube have been used: see Torpedo classes and diameters. A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient pressure of the water around the submarine, thus a submarine torpedo tube operates on the principle of an airlock. The diagram on the right illustrates the operation of a submarine torpedo tube.
The diagram does show the working of a submarine torpedo launch. A torpedo tube has a considerable number of interlocks for safety reasons. For example, an interlock prevents the breech muzzle door from opening at the same time; the submarine torpedo launch sequence is, in simplified form: Open the breech door in the torpedo room. Load the torpedo into the tube. Hook up the wire-guide connection and the torpedo power cable. Shut and lock the breech door. Turn on power to the torpedo. A minimum amount of time is required for torpedo warmup. Fire control programs are uploaded to the torpedo. Flood the torpedo tube; this may be done manually or automatically, from sea or from tanks, depending on the class of submarine. The tube must be vented during this process to allow for complete filling and eliminate air pockets which could escape to the surface or cause damage when firing. Open the equalizing valve to equalize pressure in the tube with ambient sea pressure. Open the muzzle door. If the tube is set up for Impulse Mode the slide valve will open with the muzzle door.
If Swim Out Mode is selected, the slide valve remains closed. The slide valve allows water from the ejection pump to enter the tube; when the launch command is given and all interlocks are satisfied, the water ram operates, thrusting a large volume of water into the tube at high pressure, which ejects the torpedo from the tube with considerable force. Modern torpedoes have a safety mechanism that prevents activation of the torpedo unless the torpedo senses the required amount of G-force; the power cable is severed at launch. However, if a guidance wire is used, it remains connected through a drum of wire in the tube. Torpedo propulsion systems vary but electric torpedoes swim out of the tube on their own and are of a smaller diameter. 21" weapons with fuel-burning engines start outside the tube. Once outside the tube the torpedo begins its run toward the target as programmed by the fire control system. Attack functions are programmed but with wire guided weapons, certain functions can be controlled from the ship.
For wire-guided torpedoes, the muzzle door must remain open because the guidance wire is still connected to the inside of the breech door to receive commands from the submarine's fire-control system. A wire cutter on the inside of the breech door is activated to release the wire and its protective cable; these are drawn clear of the ship prior to shutting the muzzle door. The drain cycle is a reverse of the flood cycle. Water can be moved as necessary; the tube must be vented to drain the tube since it is by gravity. Open the breech door and remove the remnants of the torpedo power cable and the guidance wire basket; the tube must be wiped dry to prevent a buildup of slime. This process is called "diving the tube" and tradition dictates that "ye who shoots, dives". Shut and lock the breech door. Spare torpedoes are stored behind the tube in racks. Speed is a desirable feature of a torpedo loading system. There are various manual and hydraulic handling systems for loading torpedoes into the tubes. Prior to the Ohio class, US SSBNs utilized manual block and tackle which took about 15 minutes to load a tube.
SSNs prior to the Seawolf class used a hydraulic system, much faster and safer in conditions where the ship needed to maneuver. The German Type 212 submarine uses a new development of the water ram expulsion system, which ejects the torpedo with water pressure to avoid acoustic detection.

Bay of Biscay
The Bay of Biscay is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, the northern coast of Spain west to Cape Ortegal; the south area of the Bay of Biscay washes over the northern coast of Spain and is known as the Cantabrian Sea. The average depth is 1,744 metres and the greatest depth is 4,735 metres; the Bay of Biscay is named after Biscay on the northern Spanish coast standing for the western Basque districts. Its name in other languages is: Asturian: golfu de Biscaya Basque: Bizkaiko golkoa Breton: pleg-mor Gwaskogn French: golfe de Gascogne Galician: golfo de Biscaia Gascon and Occitan: golf de Gasconha Latin: Sinus Biscaiensis Spanish: Golfo de Vizcaya Parts of the continental shelf extend far into the bay, resulting in shallow waters in many areas and thus the rough seas for which the region is known. Large storms occur in the bay during the winter months; the Bay of Biscay is home to some of the Atlantic Ocean's fiercest weather.
Up until recent years it was a regular occurrence for merchant vessels to founder in Biscay storms. The International Hydrographic Organization defines the limits of the Bay of Biscay as "a line joining Cap Ortegal to Penmarch Point"; the southernmost portion is the Cantabrian Sea. The main rivers that empty into the Bay of Biscay are Loire, Garonne, Adour, Bidasoa, Urumea, Urola, Artibai, Oka, Nervión, Agüera, Asón, Pas, Nansa, Sella, Nalón, Esva, Eo, Landro and Sor. In late spring and early summer a large fog triangle fills the southwestern half of the bay, covering just a few kilometers inland; as winter begins, weather becomes severe. Depressions enter from the west frequently and they either bounce north to the British Isles or they enter the Ebro Valley, dry out, are reborn in the form of powerful thunderstorms as they reach the Mediterranean Sea; these depressions cause severe weather at sea and bring light though constant rain to its shores. Sometimes powerful windstorms form if the pressure falls traveling along the Gulf Stream at great speed, resembling a hurricane, crashing in this bay with their maximum power, such as the Klaus storm.
The Gulf Stream enters the bay following the continental shelf's border anti-clockwise, keeping temperatures moderate all year long. The main cities on the shores of the Bay of Biscay are Bordeaux, Biarritz, Nantes, La Rochelle, Donostia-San Sebastián, Santander, Gijón and Avilés; the southern end of the gulf is called in Spanish "Mar Cantábrico", from the Estaca de Bares, as far as the mouth of Adour river, but this name is not used in English. It was named by Romans in the 1st century BC as Sinus Cantabrorum and Mare Gallaecum. On some medieval maps, the Bay of Biscay is marked as El Mar del los Vascos; the Bay of Biscay has been the site of many famous naval engagements over the centuries. In 1592 the Spanish defeated an English fleet during the eponymous Battle of the Bay of Biscay; the Biscay campaign of June 1795 consisted of a series of manoeuvres and two battles fought between the British Channel Fleet and the French Atlantic Fleet off the southern coast of Brittany during the second year of the French Revolutionary Wars.
USS Californian sank here after striking a naval mine on 22 June 1918. In 1920 SS Afrique sank after losing power and drifting into a reef in a storm with the loss of 575 lives. On 28 December 1943, the Battle of the Bay of Biscay was fought between HMS Glasgow and HMS Enterprise and a group of German destroyers as part of Operation Stonewall during World War II. U-667 sank on 25 August 1944 in position 46 ° 00 ′ N 01 ° 30 ′ W. All hands were lost. On 12 April 1970, Soviet submarine K-8 sank in the Bay of Biscay due to a fire that crippled the submarine's nuclear reactors. An attempt to save the sub failed, resulting in the death of forty sailors and the loss of four nuclear torpedoes. Due to the great depth, no salvage operation was attempted; the car ferries from Gijón to Nantes/Saint-Nazaire, Portsmouth to Bilbao and from Plymouth and Poole to Santander provide one of the most convenient ways to see cetaceans in European waters. Specialist groups take the ferries to hear more information. Volunteers and employees of ORCA observe and monitor cetacean activity from the bridge of the ships on Brittany Ferries' Portsmouth to Santander route.
Many species of whales and dolphins can be seen in this area. Most it is one of the few places in the world where the beaked whales, such as the Cuvier's beaked whale, have been observed frequently. Biscay Dolphin Research monitored cetacean activity from the P&O Ferries cruiseferry Pride of Bilbao, on voyages from Portsmouth to Bilbao. North Atlantic Right Whales, one of the most endangered whales, once came to the bay for feeding and for calving as well, but whaling activities by Basque people wiped them out sometime prior to 1850s; the eastern population of this species are considered to be extinct, a
German military administration in occupied France during World War II
The Military Administration in France was an interim occupation authority established by Nazi Germany during World War II to administer the occupied zone in areas of northern and western France. This so-called zone occupée was renamed zone nord in November 1942, when the unoccupied zone in the south known as zone libre was occupied and renamed zone sud, its role in France was governed by the conditions set by the Second Armistice at Compiègne after the blitzkrieg success of the Wehrmacht leading to the Fall of France. For instance, France agreed that its soldiers would remain prisoners of war until the cessation of all hostilities. Replacing the French Third Republic that had dissolved during France's defeat was the "French State", with its sovereignty and authority limited to the free zone; as Paris was located in the occupied zone, its government was seated in the spa town of Vichy in Auvergne, therefore it was more known as Vichy France. While the Vichy government was nominally in charge of all of France, the military administration in the occupied zone was a de facto Nazi dictatorship.
Its rule was extended to the free zone when it was invaded by Germany and Italy during Case Anton on 11 November 1942 in response to Operation Torch, the Allied landings in French North Africa on 8 November 1942. The Vichy government remained in existence though its authority was now curtailed; the military administration in France ended with the Liberation of France after the Normandy and Provence landings. It formally existed from May 1940 to December 1944, though most of its territory had been liberated by the Allies by the end of summer 1944. Alsace-Lorraine, annexed after the Franco-Prussian war in 1871 by the German Empire and returned to France after the First World War, was re-annexed by the Third Reich The departments of Nord and Pas-de-Calais were attached to the military administration in Belgium and Northern France, responsible for civilian affairs in the 20-kilometre wide zone interdite along the Atlantic coast. Another "forbidden zone" were areas in north-eastern France, corresponding to Lorraine and about half each of Franche-Comté, Champagne and Picardie.
War refugees were prohibited from returning to their homes, it was intended for German settlers and annexation in the coming Nazi New Order. The occupied zone consisted of the rest of northern and western France, including the two forbidden zones; the southern part of France, except for the western half of Aquitaine along the Atlantic coast, became the zone libre, where the Vichy regime remained sovereign as an independent state, though under heavy German influence due to the restrictions of the Armistice and economical dependency on Germany. It constituted a land area of 246,618 square kilometres 45 percent of France, included 33 percent of the total French labor force; the demarcation line between the free zone and the occupied zone was a de facto border, necessitating special authorisation and a laissez-passer from the German authorities to cross. These restrictions remained in place after Vichy was occupied and the zone renamed zone sud, placed under military administration in November 1942.
The Italian occupation zone consisted of small areas along the Alps border, a 50-kilometre demilitarised zone along the same. It was expanded to all territory on the left bank of the Rhône river after its invasion together with Germany of Vichy France on 11 November 1942, except for areas around Lyon and Marseille, which were added to Germany's zone sud, Corsica; the Italian occupation zone was occupied by Germany and added to the zone sud after Italy's surrender in September 1943, except for Corsica, liberated by the landings of Free French forces and local Italian troops that had switched sides to the Allies. After Germany and France agreed on an armistice following the defeats of May and June, Marshal Wilhelm Keitel and General Charles Huntzinger, representatives of the Third Reich and of the French government of Marshal Philippe Pétain signed it on 22 June 1940 at the Rethondes clearing in Compiègne Forest; as it was done at the same place and in the same railroad carriage where the armistice ending the First World War when Germany surrendered, it is known as the Second Compiègne armistice.
France was divided into an occupied northern zone and an unoccupied southern zone, according to the armistice convention "in order to protect the interests of the German Reich". The French colonial empire remained under the authority of Marshall Pétain's Vichy regime. French sovereignty was to be exercised over the whole of French territory, including the occupied zone and Moselle, but the third article of the armistice stipulated that French authorities in the occupied zone would have to obey the military administration and that Germany would exercise rights of an occupying power within it: In the occupied region of France, the German Reich exercises all of the rights of an occupying power; the French government undertakes to facilitate in every way possible the implementation of these rights, to provide the assistance of the French administrative services to that end. The French government will direct all off
Singapore the Republic of Singapore, is an island city-state in Southeast Asia. It lies one degree north of the equator, at the southern tip of the Malay Peninsula, with Indonesia's Riau Islands to the south and Peninsular Malaysia to the north. Singapore's territory consists of one main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23%; the country is known for its transition from a developing to a developed one in a single generation under the leadership of its founder Lee Kuan Yew. In 1819, Sir Stamford Raffles founded colonial Singapore as a trading post of the British East India Company. After the company's collapse in 1858, the islands were ceded to the British Raj as a crown colony. During the Second World War, Singapore was occupied by Japan, it gained independence from the British Empire in 1963 by joining Malaysia along with other former British territories, but separated two years over ideological differences, becoming a sovereign nation in 1965.
After early years of turbulence and despite lacking natural resources and a hinterland, the nation developed as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global hub for education, finance, human capital, logistics, technology, tourism and transport; the city ranks in numerous international rankings, has been recognised as the most "technology-ready" nation, top International-meetings city, city with "best investment potential", world's smartest city, world's safest country, second-most competitive country, third least-corrupt country, third-largest foreign exchange market, third-largest financial centre, third-largest oil refining and trading centre, fifth-most innovative country, the second-busiest container port. The Economist has ranked Singapore as the most expensive city to live in, since 2013, it is identified as a tax haven. Singapore is the only country in Asia with an AAA sovereign rating from all major rating agencies, one of 11 worldwide. Globally, the Port of Singapore and Changi Airport have held the titles of leading "Maritime Capital" and "Best Airport" for consecutive years, while Singapore Airlines is the 2018 "World's Best Airline".
Singapore ranks 9th on the UN Human Development Index with the 3rd highest GDP per capita. It is placed in key social indicators: education, life expectancy, quality of life, personal safety and housing. Although income inequality is high, 90% of homes are owner-occupied. According to the Democracy Index, the country is described as a "flawed democracy"; the city-state is home to 5.6 million residents, 39% of whom are foreign nationals, including permanent residents. There are four official languages: English, Mandarin Chinese, Tamil, its cultural diversity is reflected in major festivals. Pew Research has found. Multiracialism has been enshrined in its constitution since independence, continues to shape national policies in education, politics, among others. Singapore is a unitary parliamentary republic with a Westminster system of unicameral parliamentary government; the People's Action Party has won every election since self-government began in 1959. As one of the five founding members of ASEAN, Singapore is the host of the Asia-Pacific Economic Cooperation Secretariat and Pacific Economic Cooperation Council Secretariat, as well as many international conferences and events.
It is a member of the East Asia Summit, Non-Aligned Movement and the Commonwealth of Nations. The English name of Singapore is an anglicisation of the native Malay name for the country, in turn derived from Sanskrit, hence the customary reference to the nation as the Lion City, its inclusion in many of the nation's symbols. However, it is unlikely that lions lived on the island. There are however other suggestions for the origin of the name and scholars do not believe that the origin of the name is established; the central island has been called Pulau Ujong as far back as the third century CE "island at the end" in Malay. Singapore is referred to as the Garden City for its tree-lined streets and greening efforts since independence, the Little Red Dot for how the island-nation is depicted on many maps of the world and Asia, as a red dot. Singapore is referred to as the "Switzerland of Asia" in 2017 due to its neutrality on international and regional issues; the Greco-Roman astronomer Ptolemy identified a place called Sabana in the general area in the second century, the earliest written record of Singapore occurs in a Chinese account from the third century, describing the island of Pu Luo Chung.
This was itself a transliteration from the Malay name "Pulau Ujong", or "island at the end". The Nagarakretagama, a Javanese epic poem written in 1365, referred to a settlement on the island called Tumasik. In 1299, according to the Malay Annals, the Kingdom of Singapura was founded on the island by Sang Nila Utama. Although the historicity
Pearl Harbor is a lagoon harbor on the island of Oahu, west of Honolulu. It has been long visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U. S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands is now a United States Navy deep-water naval base, it is the headquarters of the United States Pacific Fleet. The U. S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The attack on Pearl Harbor by the Empire of Japan on December 7, 1941, was the immediate cause of the United States' entry into World War II. Pearl Harbor was an extensive shallow embayment called Wai Momi or Puʻuloa by the Hawaiians. Puʻuloa was regarded as the home of the shark goddess, Kaʻahupahau, her brother, Kahiʻuka, in Hawaiian legends. According to tradition, the head of the powerful Ewa chiefs, is credited with cutting a navigable channel near the present Puʻuloa saltworks, by which he made the estuary, known as "Pearl River," accessible to navigation.
Making due allowance for legendary amplification, the estuary had an outlet for its waters where the present gap is. During the early 19th century, Pearl Harbor was not used for large ships due to its shallow entrance; the interest of United States in the Hawaiian Islands grew as a result of its whaling and trading activity in the Pacific. As early as 1820, an "Agent of the United States for Commerce and Seamen" was appointed to look after American business in the Port of Honolulu; these commercial ties to the American continent were accompanied by the work of the American Board of Commissioners for Foreign Missions. American missionaries and their families became an integral part of the Hawaiian political body. Throughout the 1820s and 1830s, many American warships visited Honolulu. In most cases, the commanding officers carried letters from the U. S. Government giving advice on governmental affairs and of the relations of the island nation with foreign powers. In 1841, the newspaper Polynesian, printed in Honolulu, advocated that the U.
S. establish a naval base in Hawaii for protection of American citizens engaged in the whaling industry. The British Hawaiian Minister of Foreign Affairs Robert Crichton Wyllie, remarked in 1840 that "... my opinion is that the tide of events rushes on to annexation to the United States." From the conclusion of the Civil War, to the purchase of Alaska, to the increased importance of the Pacific states, the projected trade with countries in Asia and the desire for a duty-free market for Hawaiian staples, Hawaiian trade expanded. In 1865, the North Pacific Squadron was formed to embrace Hawaii. Lackawanna in the following year was assigned to cruise among the islands, "a locality of great and increasing interest and importance." This vessel surveyed the Northwestern Hawaiian Islands toward Japan. As a result, the United States claimed Midway Island; the Secretary of the Navy was able to write in his annual report of 1868, that in November 1867, 42 American flags flew over whaleships and merchant vessels in Honolulu to only six of other nations.
This increased activity caused the permanent assignment of at least one warship to Hawaiian waters. It praised Midway Island as possessing a harbor surpassing Honolulu's. In the following year, Congress approved an appropriation of $50,000 on March 1, 1869, to deepen the approaches to this harbor. After 1868, when the Commander of the Pacific Fleet visited the islands to look after American interests, naval officers played an important role in internal affairs, they served as arbitrators in business disputes, negotiators of trade agreements and defenders of law and order. Periodic voyages among the islands and to the mainland aboard U. S. warships were arranged for members of the Hawaiian royal family and important island government officials. When King Lunalilo died in 1873, negotiations were underway for the cession of Pearl Harbor as a port for the duty-free export of sugar to the U. S. With the election of King Kalākaua in March 1874, riots prompted landing of sailors from USS Tuscarora and Portsmouth.
The British warship, HMS Tenedos landed a token force. During the reign of King Kalākaua the United States was granted exclusive rights to enter Pearl Harbor and to establish "a coaling and repair station." Although this treaty continued in force until August 1898, the U. S. did not fortify Pearl Harbor as a naval base. As it had for 60 years, the shallow entrance constituted a formidable barrier against the use of the deep protected waters of the inner harbor; the United States and the Hawaiian Kingdom signed the Reciprocity Treaty of 1875 as supplemented by Convention on December 6, 1884, the Reciprocity Treaty was made by James Carter and ratified it in 1887. On January 20, 1887, the United States Senate allowed the Navy to exclusive right to maintain a coaling and repair station at Pearl Harbor.. The Spanish–American War of 1898 and the desire for the United States to have a permanent presence in the Pacific both contributed to the decision. Following the overthrow of the Hawaiian Kingdom, the United States Navy established a base on the island in 1899.
On December 7, 1941, the base was attacked by the Imperial Japanese Navy airplanes and midget submarines, causing the American entry into World War II. One of the main reasons that Pearl Harbor happened was because the United States had major communication breakdowns among several branches of the U. S. armed services and departments of the U. S. government. This led to the surprise Japanese attack at the Hawai
