Passage: Nelson was originally called Ffos-y-Gerddinen ("ditch of the rowan"), a relatively flat piece of land at the southern extremity of the Taff Bargoed Valley to the south of the hamlet of Llancaiach. It existed on a drovers trail from the South Wales coast towards Merthyr Tydfil and onwards to Brecon and Mid Wales, where an enterprising man built a coaching inn that he called Nelson, possibly after Admiral Lord Nelson and his victory at the Battle of Trafalgar. Had it not been for the development of the South Wales coalfield, Nelson would have remained just a coaching inn surrounded by fields. When the Llancaiach Colliery was developed from 1811, it created a need for new housing for the workers and heavy transport for the coal, which spilled onto the flat lands below the colliery.

Passage: The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Na San, at which the Viet Minh were defeated. The French used the lessons learned at Na San strong ground bases, versatile air support, and a model based on the British Burma Campaign as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".
