SS "Hsin Yu" was a Chinese Army transport ship that served during World War I.
 The 1,629 ton ship had been built in 1889.
 On 22 April 1916, the transport, with over a thousand enlisted men and officers on board, was in a thick fog while on its way to Foo Chow.
 South of the Chusan Islands, the cruiser "Hai Yung" accidentally collided with "Hsin Yu".
 A foreign engineer, nine sailors, and 20 soldiers were the only survivors.
 The ship sank with the loss of more than 1,000 lives.
 The date of the disaster has frequently (and mistakenly) been listed as 29 August 1916 although it occurred four months earlier.
The Fog of War: Eleven Lessons from the Life of Robert S. McNamara is a 2003 American documentary film about the life and times of former U.S. Secretary of Defense Robert S. McNamara illustrating his observations of the nature of modern warfare.
 The film was directed by Errol Morris and features an original score by Philip Glass.
 The title derives from the military concept of the "fog of war" depicting the difficulty of making decisions in the midst of conflict.
South of the Border is a 2009 American documentary film directed by Oliver Stone.
 The documentary premiered at the 2009 Venice Film Festival.
 Writer for the project Tariq Ali calls the documentary "a political road movie".
 Stone stated that he hopes the film will help people better understand a leader who is wrongly ridiculed "as a strongman, as a buffoon, as a clown."
The Battle of Molyatichi (Swedish: Malatitze), also known as the Battle of Dobroye, took place on August 31, 1708 at Molyatichi (present-day Belarus near the Russian border) during the Great Northern War.
 The Russian army of Peter the Great under the command of Mikhail Golitsyn successfully attacked the avatgarde of the Swedish Army of Charles XII under Carl Gustaf Roos.
 The fighting occurred in the swamp between the rivers Belaya Natopa and Chernaya Natopa.
 The Swedish forces were surprised by the Russian attack in the morning fog and withdrew to the main Swedish army.
 The swampy landscape prevented the Russian cavalry to cut off the Swedish way of retreat.
 Since the attack of the main body of the Swedish army was not part of the Russian intentions at that moment, the Russians pulled back.
 The Swede chronists noted the grown fighting skills of the Russians.
 Together with the following Battle of Lesnaya, the battle of Malatitze caused Charles XII to abort his advance to Central Russia.
The South African Air Force (SAAF, Suid-Afrikaanse Lugmag (SALM) in Afrikaans) is the air force of South Africa, with headquarters in Pretoria.
 The South African Air Force was established on 1 February 1920.
 The Air Force has seen service in World War II and the Korean War.
 From 1966 the SAAF was involved in providing infantry support in a low intensity war ("The Border War") in Angola, South-West Africa (Namibia) and Rhodesia.
 As the war progressed, the intensity of air operations increased until in the late 1980s, the SAAF were compelled to fly fighter missions against Angolan aircraft in order to maintain tactical air superiority.
 On conclusion of the Border War in 1990, aircraft numbers were severely reduced due to economic pressures as well as the cessation of hostilities with neighbouring states.
 Today the SAAF has a limited air combat capability and has been structured towards regional peace-keeping, disaster relief and maritime patrol operations.
Yandra was a 990-ton coastal steamer built by Burmeister and Wain, Copenhagen in 1928 for Coast Steamships Ltd for service in the Australian state of South Australia.
 She was requisitioned by the Royal Australia Navy in June 1940 during the Second World War for conversion to a minesweeper and anti-submarine vessel and was commissioned on 22 September 1940 as HMAS "Yandra".
 She returned to civilian service in 1946.
 She ran aground during dense fog onto South Neptune Island on 25 January 1959 and was subsequently written off.
The 1951 Polish–Soviet territorial exchange or Polish-Soviet border adjustment treaty of 1951 was a border adjustment signed in Moscow between the People's Republic of Poland and the Soviet Union regarding roughly 480 km2 of land, along their mutual border.
 The exchange was made to the decisive economic benefit of the Soviet Union due to rich deposits of coal given up by Poland; these deposits were discovered well before World War II.
 Within eight years following the agreement, the Soviets built four large coal mines there with the total mining capacity of 15 million tons annually.
The South African Border War, also known as the Namibian War of Independence, and sometimes denoted in South Africa as the Angolan Bush War, was a largely asymmetric conflict that occurred in Namibia (then South West Africa), Zambia, and Angola from 26 August 1966 to 21 March 1990.
 It was fought between the South African Defence Force (SADF) and the People's Liberation Army of Namibia (PLAN), an armed wing of the South West African People's Organisation (SWAPO).
 The South African Border War resulted in some of the largest battles on the African continent since World War II and was closely intertwined with the Angolan Civil War.
In the context of the American Civil War (1861–1865), the border states were slave states that did not declare a secession from the Union and did not join the Confederacy.
 To their north they bordered free states of the Union and to their south they bordered Confederate slave states.
 Of the 34 U.S. states in 1861, nineteen were free states and fifteen were slave states.
 Four slave states never declared a secession: Delaware, Kentucky, Maryland, and Missouri.
 Four others did not declare secession until after the Battle of Fort Sumter and were briefly considered to be border states: Arkansas, North Carolina, Tennessee, and Virginia—after this, they were less frequently called “border states”.
 Also included as a border state during the war is West Virginia, which was formed from 50 counties of Virginia and became a new state in the Union in 1863.
The Boundary Treaty of 1866 between Chile and Bolivia, also called the Mutual Benefits Treaty, was signed in Santiago de Chile on August 10, 1866 by the Chilean Foreign Affairs Minister Alvaro Covarrubias and the Bolivian Plenipotentiary in Santiago Juan R. Muñoz Cabrera.
 It drew, for the first time, the border between both countries at the 24° South parallel from the Pacific Ocean to the eastern border of Chile and defined a zone of bipartite tax collection, the "Mutual Benefits zone", and tax preferences for articles from Bolivia and Chile.
