Battle off Ulsan

The naval Battle off Ulsan (Japanese: 蔚山沖海戦 Urusan'oki kaisen; Russian: Бой в Корейском проливе, Boi v Koreiskom prolive), also known as the Battle of the Japanese Sea or Battle of the Korean Strait, took place on 14 August 1904 between cruiser squadrons of the Imperial Russian Navy and the Imperial Japanese Navy during the Russo-Japanese War, four days after the Battle of the Yellow Sea.

Background

At the start of the Russo-Japanese War, the bulk of the Russian Pacific Fleet was blockaded within the confines of Port Arthur by the Imperial Japanese Navy. However, the Russian subsidiary naval base at Vladivostok, although shelled by a Japanese squadron under the command of Vice Admiral Dewa Shigeto in March 1904, remained largely undamaged. Located at Vladivostok was a garrison force consisting of the light cruiser Bogatyr and auxiliary cruiser Lena and a stronger Vladivostok Independent Cruiser Squadron consisting of the armored cruisers Rossia, Rurik, and Gromoboi. This force was under the command of Rear Admiral Karl Jessen from 15 March – 12 June 1904, Vice Admiral Petr Bezobrazov from 12 June – 16 October 1904 and from Jessen again from 15 October 1904 until the end of the war.

Ulsan

Ulsan (Korean pronunciation: [uls͈an]), officially the Ulsan Metropolitan City, is South Korea's seventh largest metropolis with a population of over 1.1 million. It is located in the south-east of the country, neighboring Busan to the south and facing Gyeongju to the north.

Ulsan is the industrial powerhouse of South Korea, forming the heart of the Ulsan Industrial District, which is home to the world's largest automobile assembly plant operated by the Hyundai Motor Company, the world's largest shipyard operated by Hyundai Heavy Industries and the world's second largest oil refinery, owned by SK Energy. In 2012, Ulsan had a GDP per capita of $79,623, the highest of any region in South Korea.

Administrative divisions

Ulsan is divided into 4 gu (districts) and 1 gun (county).

Economy

As the center of the Ulsan Industrial District, the city is the corporate base of the multinational Hyundai conglomerate. Up to 1962, Ulsan operated as a fishing port and market centre. As part of South Korea's first five-year economic plan, Ulsan became an open port. Additionally, major industrial plants and factories were developed, including in particular an oil refinery, fertiliser plants, automobile production and heavy industries. The shipbuilding port Bangeojin became part of the city in 1962.
