Leapfrogging (strategy)
Leapfrogging, also known as island hopping, was a military strategy employed by the Allies in the Pacific War against the Empire of Japan during World War II. The key idea is to bypass heavily fortified enemy islands instead of trying to capture every island in sequence en route to a final target. The reasoning is that those islands can simply be cut off from their supply chains (leading to their eventual capitulation) rather than needing to be overwhelmed by superior force, thus speeding up progress and reducing losses of troops and materiel. Background By the late 19th century, the U.S. had several interests in the western Pacific to defend; namely, access to the Chinese market, and its colonies – the Philippines and Guam – which the U.S. had gained as a result of the Spanish–American War (1898). After Japan's victories in the Sino-Japanese War (1894–95) and the Russo-Japanese War of 1904, the U.S. began to regard Japan as a potential threat to its interests in th ...

Second World War Asia 1943-1945 Map De
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariana Islands
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Occupation Of The Philippines
The Japanese occupation of the Philippines (Filipino: ''Pananakop ng mga Japones sa Filipinas''; ja, 日本のフィリピン占領, Nihon no Firipin Senryō) occurred between 1942 and 1945, when Imperial Japan occupied the Commonwealth of the Philippines during World War II. The invasion of the Philippines started on 8 December 1941, ten hours after the attack on Pearl Harbor. As at Pearl Harbor, American aircraft were severely damaged in the initial Japanese attack. Lacking air cover, the American Asiatic Fleet in the Philippines withdrew to Java on 12 December 1941. General Douglas MacArthur was ordered out, leaving his men at Corregidor on the night of 11 March 1942 for Australia, 4,000 km away. The 76,000 starving and sick American and Filipino defenders in Bataan surrendered on 9 April 1942, and were forced to endure the infamous Bataan Death March on which 7,000–10,000 died or were murdered. The 13,000 survivors on Corregidor surrendered on 6 May. Japan o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Douglas MacArthur
Douglas MacArthur (26 January 18805 April 1964) was an American military leader who served as General of the Army for the United States, as well as a field marshal to the Philippine Army. He had served with distinction in World War I, was Chief of Staff of the United States Army during the 1930s, and he played a prominent role in the Pacific theater during World War II. MacArthur was nominated for the Medal of Honor three times, and received it for his service in the Philippines campaign. This made him along with his father Arthur MacArthur Jr. the first father and son to be awarded the medal. He was one of only five men to rise to the rank of General of the Army in the U.S. Army, and the only one conferred the rank of field marshal in the Philippine Army. Raised in a military family in the American Old West, MacArthur was valedictorian at the West Texas Military Academy where he finished high school, and First Captain at the United States Military Academy at West Poin ...

Rabaul
Rabaul () is a township in the East New Britain province of Papua New Guinea, on the island of New Britain. It lies about 600 kilometres to the east of the island of New Guinea. Rabaul was the provincial capital and most important settlement in the province until it was destroyed in 1994 by falling ash from a volcanic eruption in its harbour. During the eruption, ash was sent thousands of metres into the air, and the subsequent rain of ash caused 80% of the buildings in Rabaul to collapse. After the eruption the capital was moved to Kokopo, about away. Rabaul is continually threatened by volcanic activity, because it is on the edge of the Rabaul caldera, a flooded caldera of a large pyroclastic shield. Rabaul was planned and built around the harbour area known as Simpsonhafen (Simpson Harbour) during the German New Guinea administration, which controlled the region between 1884 and formally through 1919. Rabaul was selected as the capital of the German New Guinea administration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blockade
A blockade is the act of actively preventing a country or region from receiving or sending out food, supplies, weapons, or communications, and sometimes people, by military force. A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area. While most blockades historically took place at sea, blockades are also used on land to prevent entrance of an area. For example, Armenia is a landlocked country that Turkey and Azerbaijan blockade. Thus, Armenia cannot conduct international trade through those countries, and mainly trades through Georgia. This restricts the country's economic development. A blockading power can seek to cut off all maritime transport from and to the blockaded country; although stopping all land transport to an ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

Japanese Imperial Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

The Great Pacific War
''The Great Pacific War'' was a 1925 novel by British author Hector Charles Bywater which discussed a hypothetical future war between Japan and the United States. The novel accurately predicted a number of details about the Pacific Campaign of World War II. Bywater was a naval correspondent for the '' London Daily Telegraph''. Plot In ''The Great Pacific War'', the war begins with a Japanese invasion of Manchuria, Formosa and Korea. Japan then stages a surprise attack which results in the nearly complete destruction of the Panama Canal, by exploding a freighter full of explosives in the Gaillard Cut. Legacy In ''Infamy: Pearl Harbor and Its Aftermath'', John Toland states that Isoroku Yamamoto was in the US in 1925 and might have read the New York newspapers' reviews of "The Great Pacific War," which was translated into Japanese and read by senior officers of the Japanese Imperial Navy.

Hector Charles Bywater
Hector Charles Bywater (21 October 1884 in London – 16 or 17 August 1940 in London) was a British journalist and military writer. Biography Bywater was the second son of a middle class Welshman. The family had emigrated into the United States in 1901. At age of 19 he started part-time job writing naval articles for the ''New York Herald'' and later was sent as foreign correspondent to London. There he became a naval spy for Britain.

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...
