History by Frederick Dielman
History (derived from Ancient Greek ἱστορία (historía) 'inquiry; knowledge acquired by investigation') is the systematic study and documentation of the human past.
The period of events before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is incomplete and still has debatable mysteries.
History is an academic discipline which uses a narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians debate which narrative best explains an event, as well as the significance of different causes and effects. Historians debate the nature of history as an end in itself, and its usefulness in giving perspective on the problems of the present.
Stories common to a particular culture, but not supported by external sources (such as the tales surrounding King Arthur), are usually classified as cultural heritage or legends. History differs from myth in that it is supported by verifiable evidence. However, ancient cultural influences have helped create variant interpretations of the nature of history, which have evolved over the centuries and continue to change today. The modern study of history is wide-ranging, and includes the study of specific regions and certain topical or thematic elements of historical investigation. History is taught as a part of primary and secondary education, and the academic study of history is a major discipline in universities.
Herodotus, a 5th-century BC Greek historian, is often considered the "father of history", as one of the first historians in the Western tradition, though he has been criticized as the "father of lies". Along with his contemporary Thucydides, he helped form the foundations for the modern study of past events and societies. Their works continue to be read today, and the gap between the culture-focused Herodotus and the military-focused Thucydides remains a point of contention or approach in modern historical writing. In East Asia, a state chronicle, the Spring and Autumn Annals, was reputed to date from as early as 722 BC, though only 2nd-century BC texts have survived. (Full article...)

Lieutenant-General Sir Frederick Arthur Montague "Boy" Browning, GCVO, KBE, CB, DSO (20 December 1896 – 14 March 1965) was a senior officer of the British Army who has been called the "father of the British airborne forces". He was also an Olympic bobsleigh competitor, and the husband of author Daphne du Maurier.
Educated at Eton College and then at the Royal Military College, Sandhurst, Browning was commissioned as a second lieutenant into the Grenadier Guards in 1915. During the First World War, he fought on the Western Front, and was awarded the Distinguished Service Order for conspicuous gallantry during the Battle of Cambrai in November 1917. In September 1918, he became aide de camp to General Sir Henry Rawlinson. (Full article...) -
The Bougainville counterattack, also known as the Second Battle of Torokina, was an unsuccessful Japanese offensive against the Allied base at Cape Torokina on Bougainville Island during the Pacific Theater of World War II. The Japanese attack began on 8 March 1944 after months of preparation and was repulsed by United States Army forces in fighting which lasted until 25 March. The attack was hampered by inaccurate intelligence and poor planning and was pushed back by the well-prepared Allied defenders, who greatly outnumbered the Japanese force. The Japanese suffered severe casualties, while Allied losses were light.
The goal of the offensive was to destroy the Allied beachhead, which accommodated three strategically important airfields. The Japanese mistakenly believed that their forces were about as large as the units deployed to defend the Allied positions. The Allies detected Japanese preparations for the attack shortly after they began in early 1944 and strengthened the base's defenses. None of the three Japanese forces which conducted the attack was able to penetrate far into the Allied perimeter, although there was intense fighting for several positions. (Full article...) -
HMS Indefatigable was the lead ship of her class of three battlecruisers built for the Royal Navy during the first decade of the 20th Century. When the First World War began, Indefatigable was serving with the 2nd Battlecruiser Squadron (BCS) in the Mediterranean, where she unsuccessfully pursued the battlecruiser Goeben and the light cruiser Breslau of the German Imperial Navy as they fled toward the Ottoman Empire. The ship bombarded Ottoman fortifications defending the Dardanelles on 3 November 1914, then, following a refit in Malta, returned to the United Kingdom in February where she rejoined the 2nd BCS.
Indefatigable was sunk on 31 May 1916 during the Battle of Jutland, the largest naval battle of the war. Part of Vice-Admiral Sir David Beatty's Battlecruiser Fleet, she was hit several times in the first minutes of the "Run to the South", the opening phase of the battlecruiser action. Shells from the German battlecruiser Von der Tann caused an explosion ripping a hole in her hull, and a second explosion hurled large pieces of the ship 200 feet (60 m) in the air. Only three of the crew of 1,019 survived. (Full article...) -
Lieutenant-General Sir Brian Gwynne Horrocks, KCB, KBE, DSO, MC (7 September 1895 – 4 January 1985) was a British Army officer, chiefly remembered as the commander of XXX Corps in Operation Market Garden and other operations during the Second World War. He also served in the First World War and the Russian Civil War, was taken prisoner twice, and competed in the modern pentathlon at the 1924 Paris Olympics. Later he was a television presenter, wrote books on military history, and was Black Rod in the House of Lords for 14 years.
In 1940 Horrocks commanded a battalion during the Battle of France, the first time he served under Bernard Montgomery, the most prominent British commander of the war. Montgomery later identified Horrocks as one of his most able officers, appointing him to corps commands in both North Africa and Europe. In 1943, Horrocks was seriously wounded and took more than a year to recover before returning to command a corps in Europe. It is likely that this period out of action meant he missed out on promotion; his contemporary corps commanders in North Africa, Oliver Leese and Miles Dempsey, went on to command at army level and above. Horrocks' wound continued to impair his health and led to his early retirement from the army after the war. (Full article...) -
The Almirante Latorre class consisted of two super-dreadnought battleships designed by the British company Armstrong Whitworth for the Chilean Navy. They were intended to be Chile's entries to the South American dreadnought race, but both were purchased by the Royal Navy prior to completion for use in the First World War. Only one, Almirante Latorre (HMS Canada), was finished as a battleship; Almirante Cochrane (HMS Eagle), was converted to an aircraft carrier. Under their Chilean names, they honored Admirals (Almirantes) Juan José Latorre and Thomas Cochrane; they took their British names from what was then a dominion of Canada and a traditional ship name in the Royal Navy.
At the end of the 19th and the beginning of the 20th centuries, Chile was engaged in an intense naval competition with its neighbor Argentina. This ended peacefully in 1902, but less than a decade later Argentina responded to Brazil's order for two dreadnoughts with two of its own. The Chilean congress responded by allocating money for its own dreadnoughts, which were ordered from the United Kingdom despite a strong push from the American government for the contracts, probably due to Chile's traditionally strong ties with the British.

The Rivadavia class consisted of two battleships designed by the American Fore River Shipbuilding Company for the Argentine Navy. Named Rivadavia and Moreno after important figures in Argentine history, they were Argentina's entry in the South American dreadnought race and a counter to Brazil's two Minas Geraes-class battleships.
In 1904, Brazil scrapped a previous naval building program in favor of an order that included three warships of the new "dreadnought" type, despite signs that such an action would spark a South American naval arms race. To counter this acquisition by a major rival, Argentina began seeking bids for at least two dreadnoughts in 1908. Over the next two years, shipbuilders from five countries vied for the contracts, complemented by efforts from their respective governments. Argentina was able to play this hyper-competitive environment to its own advantage by rejecting all of the initial proposals and calling for new ones that required the best aspects of each. They then repeated this process, despite complaints from shipbuilders that their trade secrets were being given away. The contracts were awarded to the lowest bidder, Fore River, in early 1910. This move shocked the European bidders, but could partly be explained by the American steel trust's ability to produce steel at a lower cost than any other country. (Full article...) -
Jesus (c. 6 to 4 BC – AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and many other names and titles, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity, the world's largest religion. Most Christians believe Jesus to be the incarnation of God the Son and the awaited messiah, the Christ that is prophesied in the Old Testament.
Virtually all modern scholars of antiquity agree that Jesus existed historically. Accounts of Jesus's life are contained in the Gospels, especially the four canonical Gospels in the New Testament. Academic research has yielded various views on the historical reliability of the Gospels and how closely they reflect the historical Jesus. Jesus was circumcised at eight days old, was baptized by John the Baptist as a young adult, and after 40 days and nights of fasting in the wilderness, began his own ministry. Being an itinerant teacher, he was often referred to as "rabbi". Jesus often debated with fellow Jews on how to best follow God, engaged in healings, taught in parables, and gathered followers, among whom twelve were his primary disciples. He was arrested in Jerusalem and tried by the Jewish authorities, turned over to the Roman government, and crucified on the order of Pontius Pilate, the Roman prefect of Judaea. After his death, his followers became convinced that he rose from the dead, and following his ascension, the community they formed eventually became the early Christian Church that expanded as a worldwide movement. Accounts of his teachings and life were initially conserved by oral transmission, which was the source of the written Gospels. (Full article...) -
1305 letter (a roll measuring 302 by 50 centimetres (9.91 by 1.64 ft)) from the Ilkhan Mongol Öljaitü to King Philip IV of France, suggesting military collaboration.
Several attempts at a Franco-Mongol alliance against the Islamic caliphates, their common enemy, were made by various leaders among the Frankish Crusaders and the Mongol Empire in the 13th century. Such an alliance might have seemed an obvious choice: the Mongols were already sympathetic to Christianity, given the presence of many influential Nestorian Christians in the Mongol court. The Franks—Western Europeans, and those in the Levantine Crusader states—were open to the idea of support from the East, in part owing to the long-running legend of the mythical Prester John, an Eastern king in an Eastern kingdom who many believed would one day come to the assistance of the Crusaders in the Holy Land. The Franks and Mongols also shared a common enemy in the Muslims. However, despite many messages, gifts, and emissaries over the course of several decades, the often-proposed alliance never came to fruition.
Contact between Europeans and Mongols began around 1220, with occasional messages from the papacy and European monarchs to Mongol leaders such as the Great Khan, and subsequently to the Ilkhans in Mongol-conquered Persia. Communications tended to follow a recurring pattern: the Europeans asked the Mongols to convert to Western Christianity, while the Mongols responded with demands for submission and tribute. The Mongols had already conquered many Christian and Muslim nations in their advance across Asia, and after destroying the Nizaris of Alamut and the Muslim Abbasid and Ayyubid dynasties, for the next few generations fought the remaining Islamic power in the region, the Egyptian Mamluks. Hethum I, king of the Christian nation of Cilician Armenia, had submitted to the Mongols in 1247, and strongly encouraged other monarchs to engage in a Christian–Mongol alliance, but was only able to persuade his son-in-law, Prince Bohemond VI of the Crusader state of Antioch, who submitted in 1260. Other Christian leaders such as the Crusaders of Acre were more mistrustful of the Mongols, perceiving them as the most significant threat in the region. The Barons of Acre therefore engaged in an unusual passive alliance with the Muslim Mamluks, allowing Egyptian forces to advance unopposed through Crusader territory to engage and defeat the Mongols at the pivotal Battle of Ain Jalut in 1260.

The Gloucestershire Regiment, commonly referred to as the Glosters, was a line infantry regiment of the British Army from 1881 until 1994. It traced its origins to Colonel Gibson's Regiment of Foot, which was raised in 1694 and later became the 28th (North Gloucestershire) Regiment of Foot. The regiment was formed by the merger of the 28th Regiment with the 61st (South Gloucestershire) Regiment of Foot. It inherited the unique distinction in the British Army of wearing a badge on the back of its headdress as well as the front, a tradition that originated with the 28th Regiment after it fought in two ranks back to back at the Battle of Alexandria in 1801. At its formation the regiment comprised two regular, two militia and two volunteer battalions, and saw its first action during the Second Boer War.
Before the First World War, the regiment's four auxiliary battalions were converted to three Territorial Force battalions and a Special Reserve battalion, and a further 18 battalions were added to the regiment's establishment during the war. Sixteen battalions of the regiment saw active service in France and Flanders, Italy, Gallipoli, Egypt, Mesopotamia, Persia and Salonika, losing a total of 8,100 men killed and winning 72 different battle honours. Four awards of the Victoria Cross (VC) were made to soldiers serving with the regiment. The wartime battalions were disbanded as the war ended, and just before the Second World War, two of the territorial battalions were re-purposed and ceased to have any affiliation with the regiment. On the eve of the war, the remaining territorial battalion was duplicated, and another five battalions were raised on the outbreak of war, though most of these were disbanded or re-purposed as the war progressed. Four battalions saw active service under the regiment's colours during the war. The 2nd and 5th Battalions both fought in the Battle of France and, after being lost almost in its entirety during the Battle of Dunkirk, the re-formed 2nd Battalion landed at Gold Beach on D-Day and fought in the Allied campaign in North-West Europe. The 1st Battalion was involved in the retreat from Rangoon during the Japanese conquest of Burma, and the 10th Battalion saw active service in the defeat of Japanese forces during the Burma Campaign 1944–45.

On 9 February 1945, a force of Allied Bristol Beaufighter aircraft suffered many losses during an attack on the German destroyer Z33 and its escorting vessels; the operation was called Black Friday by the survivors. The German ships were sheltering in a strong defensive position in Førde Fjord, Norway, forcing the Allied aircraft to attack through massed anti-aircraft fire (FlaK).
The Beaufighters and their escort of Mustang Mk III fighters from 65 Squadron RAF were intercepted by twelve Focke-Wulf Fw 190s of Jagdgeschwader 5 (Fighter Wing 5) of the Luftwaffe. The Allies damaged at least two of the German ships for the loss of seven Beaufighters shot down by FlaK. Two Beaufighters and a Mustang were shot down by the Fw 190s and four or five of the German aircraft were shot down by the Allied aircraft, including that of the ace Rudi Linz. (Full article...) -
A Westland Wessex helicopter delivering supplies at Ascension Island in May 1982
The 1982 British military campaign to recapture the Falkland Islands
depended on complex logistical arrangements. The logistical difficulties of operating 7,000 nautical miles (8,100 mi; 13,000 km) from home were formidable. The Argentine invasion of the Falkland Islands came at a time when the Royal Navy was experiencing a reduction in its amphibious capability, but it still possessed the aircraft carriers HMS Hermes and Invincible, the landing platform dock (LPD) ships HMS Fearless and Intrepid, and six landing ship logistics (LSL) ships. To provide the necessary logistic support, the Royal Navy's ships were augmented by ships taken up from trade (STUFT).
The British Army and Royal Navy developed a base at Ascension Island, a British territory in the mid-Atlantic 3,700 nautical miles (4,300 mi; 6,900 km) from the UK and 3,300 nautical miles (3,800 mi; 6,100 km) from the Falkland Islands. Although it had an airfield with an excellent runway, there was only a small hardstand area for parking aircraft and no parallel taxiways. There was an anchorage, but no port facilities—just a lone jetty. Ascension was used as a convenient place for the amphibious ships to re-stow their equipment, and as a base for Hercules transport aircraft, which were modified by the addition of auxiliary fuel tanks and aerial refuelling probes. With the support of Victor tankers, these modifications allowed the transports to deliver priority supplies to the South Atlantic. (Full article...) -
The Fall of Kampala, also known as the Liberation of Kampala (Kiswahili: Kukombolewa kwa Kampala), was a battle during the Uganda–Tanzania War in 1979, in which the combined forces of Tanzania and the Uganda National Liberation Front (UNLF) attacked and captured the Ugandan capital, Kampala. As a result, Ugandan President Idi Amin was deposed, his forces were scattered, and a UNLF government was installed.
Amin had seized power in Uganda in 1971 and established a brutal dictatorship. Seven years later he attempted to invade Tanzania to the south. Tanzania repulsed the assault and launched a counter-attack into Ugandan territory. After routing the Ugandans and their Libyan allies in Entebbe, the Tanzanians revised their existing offensive designs for Kampala. The plans called for the 208th Brigade to advance from the south, spearheaded by Lieutenant Colonel Ben Msuya's 800-strong 19th Battalion, which was to secure the centre of the city. The 207th Brigade and a UNLF battalion were to attack from the west, while the 201st Brigade was to establish roadblocks to the north to prevent Ugandan units from withdrawing. An eastern corridor was left open to allow the Libyans to evacuate to Jinja and fly out of the country. Amin prepared for the defence of Kampala but fled through the gap. (Full article...) -
SMS Wettin ("His Majesty's Ship Wettin") was a pre-dreadnought battleship of the Wittelsbach class of the German Kaiserliche Marine (Imperial Navy). She was built by Schichau Seebeckwerft in Danzig. Wettin was laid down in October 1899, and was completed October 1902. She and her sister ships—Wittelsbach, Zähringen, Schwaben and Mecklenburg—were the first capital ships built under the Navy Law of 1898. Wettin was armed with a main battery of four 24 cm (9.4 in) guns and had a top speed of 18 knots (33 km/h; 21 mph).
Wettin saw service in I Squadron of the German fleet for most of her career, along with her sister ships. She was occupied with extensive annual training, as well as making good-will visits to foreign countries. The training exercises provided the framework for the High Seas Fleet's operations during World War I. The ship was decommissioned in June 1911 as dreadnought battleships began to enter service but was reactivated for duty as a gunnery training ship between December 1911 and mid-1914.

Edgar James Kain, DFC (27 June 1918 – 7 June 1940) was a New Zealand fighter pilot and flying ace who flew in the Royal Air Force (RAF) during the Second World War.
Born in Hastings, New Zealand, Kain developed an early interest in aviation and joined the RAF in 1936. He completed his flight training the following year and was posted to the RAF's No. 73 Squadron, flying the Gloster Gladiator and then the Hawker Hurricane. On the outbreak of the Second World War the squadron was dispatched to France. Kain began flying operational sorties during the Phoney War and gained his first aerial victory, a German bomber, in November 1939. He claimed his fifth aerial victory in March 1940, becoming the RAF's first flying ace of the Second World War as well as its first recipient of the Distinguished Flying Cross. His success early in the war and consequent media reports made him well known in Britain and the Dominions. (Full article...) -
An Alpha calutron tank removed from the magnet for recovery of uranium-235
A calutron is a mass spectrometer originally designed and used for separating the isotopes of uranium. It was developed by Ernest Lawrence during the Manhattan Project and was based on his earlier invention, the cyclotron. Its name was derived from California University Cyclotron, in tribute to Lawrence's institution, the University of California, where it was invented. Calutrons were used in the industrial-scale Y-12 uranium enrichment plant at the Clinton Engineer Works in Oak Ridge, Tennessee. The enriched uranium produced was used in the Little Boy atomic bomb that was detonated over Hiroshima on 6 August 1945.
The calutron is a type of sector mass spectrometer, an instrument in which a sample is ionized and then accelerated by electric fields and deflected by magnetic fields. The ions ultimately collide with a plate and produce a measurable electric current. Since the ions of the different isotopes have the same electric charge but different masses, the heavier isotopes are deflected less by the magnetic field, causing the beam of particles to separate into several beams by mass, striking the plate at different locations. The mass of the ions can be calculated according to the strength of the field and the charge of the ions. During World War II, calutrons were developed to use this principle to obtain substantial quantities of high-purity uranium-235, by taking advantage of the small mass difference between uranium isotopes.

Banknote credit: Bank of Finland; photographed by Andrew ShivaThe Finnish markka was the currency of Finland from 1860 to 2002. The currency was divided into 100 pennies and was first introduced by the Bank of Finland to replace the Russian ruble at a rate of four markkaa to one ruble. The markka was replaced by the euro on 1 January 2002 and ceased to be legal tender on 28 February later that year.
This picture shows a 20-markka banknote issued in 1862, as part of the first issue of markka banknotes (1860 to 1862), for the Grand Duchy of Finland, then an autonomous part of the Russian Empire; 1862 was also the first year of issue for this particular denomination. The banknote's obverse depicts the coat of arms of Finland on a Russian double-headed eagle, and was personally signed by the director and the cashier of the Bank of Finland. The text on the obverse is in Swedish, whereas the reverse is primarily in Russian and Finnish. -

I was two months in bed sore from the whipping. My master come after I was whipped; he discharged the overseer." The slave pictured here escaped from a plantation in Mississippi, made his way to Union forces, and joined the U.S. Army at the Union garrison located at Baton Rouge.
Slavery in the United States began soon after the English colonists first settled in North America. From about the 1640s until 1865, people of African descent were legally enslaved within the boundaries of the present U.S. mostly by whites, but also by a comparatively tiny number of American Indians and free blacks. By 1860, the slave population in the U.S. had grown to 4 million. -

Jürgen Ehlers (German: [ˈjʏʁɡŋ̩ ˈeːlɐs]; 29 December 1929 – 20 May 2008) was a German physicist who contributed to the understanding of Albert Einstein's theory of general relativity. From graduate and postgraduate work in Pascual Jordan's relativity research group at Hamburg University, he held various posts as a lecturer and, later, as a professor before joining the Max Planck Institute for Astrophysics in Munich as a director. In 1995, he became the founding director of the newly created Max Planck Institute for Gravitational Physics in Potsdam, Germany.
Ehlers' research focused on the foundations of general relativity as well as on the theory's applications to astrophysics. He formulated a suitable classification of exact solutions to Einstein's field equations and proved the Ehlers–Geren–Sachs theorem that justifies the application of simple, general-relativistic model universes to modern cosmology. He created a spacetime-oriented description of gravitational lensing and clarified the relationship between models formulated within the framework of general relativity and those of Newtonian gravity. In addition, Ehlers had a keen interest in both the history and philosophy of physics and was an ardent populariser of science. (Full article...)On this day
