The Fourth Enemy Offensive (Serbo-Croatian: Četvrta neprijateljska ofenziva/ofanziva), codenamed Fall Weiss, was a combined Axis strategic offensive launched during against the Partisans throughout occupied Yugoslavia. It is one of the most significant confrontations of the Yugoslav National Liberation War (a theater of World War II). The offensive took place in early 1943, between 20 January and mid-to-late March 1943.

The operation is most remembered in Yugoslavia for its final phase, the Battle of the Neretva (Bitka na Neretvi) named after the Neretva river. The final phase is also known as the Battle for the Wounded (Bitka za ranjenike).

In late 1942, with the Axis situation in North Africa deteriorating, the German high command became concerned about the possibility of an Allied landing in the Balkans. This was of particular concern due to the substantial resources they were extracting from Yugoslavia, including timber, copper and bauxite. In the event of an Allied landing, resistance forces in Yugoslavia would be likely to interfere with German defensive operations as well as continued resource extraction. As a result, on 16 December 1942, Hitler ordered the Armed Forces Commander in South-East Europe, Generaloberst Alexander Löhr to crush the resistance in Yugoslavia. In a meeting of 18–19 December, the General Staff of the Wehrmacht decided on the destruction of the Bihać Republic. On 8 January, Löhr and Mario Roatta, commander of the 2nd Italian army, met in Zagreb and devised a detailed plan.

Neretva (Bosnian: Neretva, Italian: Narenta, in Cyrillic: Неретва, pronounced [nɛ̌rɛtʋa]) is the largest river of the eastern part of the Adriatic basin. It has been harnessed and controlled to a large extent by four HE power-plants with large dams (higher than 15 meters) and their storage lakes, but it is still recognized for its natural beauty and diversity of its landscape.

Freshwater ecosystems have suffered a lot from an increasing population and the associated development pressures. One of the most valuable natural resources of Bosnia and Herzegovina and Croatia is its freshwater richness contained by an abundant wellspring and clear rivers, indeed, a natural treasure of great importance yet to be evaluated, acknowledge and appreciated. Situated between the major regional rivers (Drina river on the east, Una river on the west and the Sava river) the Neretva basin contains the most significant portion of fresh drinking water.

In that dense water system network the Neretva river also holds a significant position among rivers of the Dinaric Alps region, especially regarding its diverse ecosystems and habitats, flora and fauna, cultural and historic heritage, but also as an Area of Outstanding Natural Beauty.

Song In (in hangul 송인, in hanja 宋仁) was a civil official in the mid-Goryeo era who became the intermediary founder of the Jincheon Song clan. His highest post was munha pyeongjangsa (문하 평장사).

Baek was a position of politicians who were responsible for administration, judicial affairs and economy in the district.

Bernard Herrmann (June 29, 1911 – December 24, 1975) was an American composer noted for his work in motion pictures.

An Academy Award-winner (for The Devil and Daniel Webster, 1941), Herrmann is particularly known for his collaborations with director Alfred Hitchcock, most famously Psycho, North by Northwest, The Man Who Knew Too Much, and Vertigo. He also composed notable scores for many other movies, including Citizen Kane, The Ghost and Mrs. Muir, Cape Fear, and Taxi Driver. He worked extensively in radio drama (most notably for Orson Welles), composed the scores for several fantasy films by Ray Harryhausen, and many TV programs including most notably Rod Serling's The Twilight Zone and Have Gun–Will Travel.

Herrmann, the son of a Jewish middle class family of Russian origin, was born in New York City. He attended high school at DeWitt Clinton High School, at that time on 10th avenue and 59th Street in New York City. His father encouraged music activity, taking him to the opera, and encouraging him to learn the violin. After winning a $100 composition prize at the age of thirteen, he decided to concentrate on music, and went to New York University where he studied with Percy Grainger and Philip James. He also studied at the Juilliard School and, at the age of twenty, formed his own orchestra, the New Chamber Orchestra of New York.

Yul Brynner (Russian: Юлий Борисович Бринер, Yuliy Borisovich Bryner; July 11, 1920  – October 10, 1985) was a Russian-born stage and film actor. He was best known for his portrayal of Mongkut, king of Siam, in the Rodgers and Hammerstein musical The King and I, for which he won an Academy Award for Best Actor for the film version; he also played the role more than 4,500 times onstage. He is also remembered as Rameses II in the 1956 Cecil B. DeMille blockbuster The Ten Commandments, General Bounine in Anastasia and Chris Adams in The Magnificent Seven. Brynner was noted for his distinctive voice and for his shaven head, which he maintained as a personal trademark long after adopting it for his initial role in The King and I. He was also a photographer and the author of two books.

Yul Brynner was born Yuliy Borisovich Bryner in 1920. He exaggerated his background and early life for the press, claiming that he was born Taidje Khan of part-Mongol-Tatar parentage, on the Russian island of Sakhalin. In reality, he was born at home in a four-storey residence at 15 Aleutskaya Street, Vladivostok, in the Far Eastern Republic (present-day Primorsky Krai, Russia). He also occasionally referred to himself as Julius Briner,Jules Bryner, or Youl Bryner. A biography written by his son, Rock Brynner, in 1989 clarified these issues.
