September 15 in History

The War of 1812 was a conflict initiated by the United States against the United Kingdom and its allies fought mainly in North America and at sea during the wider Napoleonic Wars. The United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.

HMS Whiting, built in 1811 by Thomas Kemp as a Baltimore pilot schooner, was launched as Arrow. On 8 May 1812 a British navy vessel seized her under Orders in Council, for trading with the French. The Royal Navy re-fitted her and then took her into service under the name HMS Whiting. In 1816, after four years service, Whiting was sent to patrol the Irish Sea for smugglers. She grounded on the Doom Bar. When the tide rose, she became flooded and was deemed impossible to refloat.

The Captaincy General of Guatemala, also known as the Kingdom of Guatemala, was an administrative division of the Spanish Empire, under the viceroyalty of New Spain in Central America, including present-day Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, and the Mexican state of Chiapas.

HMS Beagle was a Cherokee-class 10-gun brig-sloop of the Royal Navy, one of more than 100 ships of this class. The vessel, constructed at a cost of £7,803, was launched on 11 May 1820 from the Woolwich Dockyard on the River Thames. Later reports say the ship took part in celebrations of the coronation of George IV, passing under the old London Bridge, and was the first rigged man-of-war afloat upriver of the bridge. There was no immediate need for Beagle, so she "lay in ordinary", moored afloat but without masts or rigging. She was then adapted as a survey barque and took part in three survey expeditions.

The Franco-Prussian War, occasionally known as the Franco-German War, and sometimes referred to in France as the War of 1870, was a conflict between France and the North German Confederation led by Prussia. Lasting from 19 July 1870 to 28 January 1871, the conflict was caused primarily by France's determination to reassert its dominant position in continental Europe, which appeared in question following the decisive Prussian victory over Austria in 1866.

The New Culture Movement was a progressive sociopolitical movement in China during the 1910s and 1920s. Participants criticized many aspects of traditional Chinese society, favoring their substitution with new formulations of Chinese culture informed by modern and contemporary ideals of mass political participation. Arising out of disillusionment with traditional Chinese culture following the failure of the Republic of China to address China's problems, it featured scholars such as Chen Duxiu, Cai Yuanpei, Chen Hengzhe, Li Dazhao, Lu Xun, Zhou Zuoren, He Dong, Qian Xuantong, Liu Bannong, Bing Xin and Hu Shih, many of whom were classically educated, who led a revolt against Confucianism. The movement was launched by the writers of New Youth magazine, where these intellectuals promoted a new society based on unconstrained individuals rather than the traditional Confucian system. In 1917, Hu Shih put forward his famous "eight principles", which advocated for abandoning ancient traditional writing methods for ones that more accurately represented vernacular speech.

The Battle of Dobro Pole, also known as the Breakthrough at Dobro Pole, was a World War I battle fought between 15 and 18 September 1918.

The offensive and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.

The Reich Citizenship Law restricted citizenship to people of "German or related blood", reducing others to state subjects without full rights.

The North American F-86 Sabre, sometimes called the Sabrejet, is a transonic jet powered fighter aircraft. Produced by North American Aviation, the Sabre is best known as the United States' first swept-wing fighter that could counter the swept-wing Soviet MiG-15 in high-speed dogfights in the skies of the Korean War (1950–1953), fighting some of the earliest jet-to-jet battles. Considered one of the best and most important fighter aircraft in that war, the F-86 is also rated highly in comparison with fighters of other eras. Although it was developed in the late 1940s and was outdated by the end of the 1950s, the Sabre proved versatile and adaptable and continued as a front-line fighter in numerous air forces.

The Gleision Colliery mining accident was a mining accident which occurred on 15 September 2011 at the Gleision Colliery, a drift mine at Cilybebyll in Neath Port Talbot, in Wales. The accident occurred while seven miners were working with explosives on a narrow coal seam. Following a blasting operation into a separate disused flooded mine network to increase air-circulation, the tunnel in which the miners were working began to fill with water. Three of the miners escaped, with one being taken to hospital with life-threatening injuries, while the others were trapped underground. A search and rescue operation was launched to locate the four remaining miners, but they were found deceased the following day. The incident is the worst mining disaster to occur in Wales for three decades.
