context_page_description: 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, Zambia, and Angola from 26 August 1966 to 21 March 1990. It was fought between the South African Defence Force and the People's Liberation Army of Namibia, an armed wing of the South West African People's Organisation. 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.
  Following several years of unsuccessful petitioning through the United Nations and the International Court of Justice for Namibian independence, SWAPO formed the PLAN in 1962 with material assistance from the Soviet Union, China, and sympathetic African states such as Tanzania, Ghana, and Algeria. Fighting broke out between PLAN and the South African authorities in August 1966. Between 1975 and 1988 the SADF staged massive conventional raids into Angola and Zambia to eliminate PLAN's forward operating bases.
context_section_description: The initial terms of the Geneva Protocol and Security Council Resolution 435 provided the foundation from which a political settlement in South West Africa could proceed: holding of elections for a constitutional assembly, confinement of both PLAN and the SADF to their respective bases, the subsequent phased withdrawal of all but 1,500 SADF troops, demobilisation of all paramilitary forces that belonged to neither the SADF nor to the police, and the return of refugees via designated entry points to participate in elections. Responsibility for implementing these terms rested with UNTAG, which would assist in the SADF withdrawal, monitor the borders, and supervise the demobilisation of paramilitary units.
  Controversy soon arose over the size of UNTAG's military component, as the member states of the Security Council expected to cover the majority of the costs were irritated by its relatively large size. However, Angola, Zambia, and other states sympathetic to PLAN insisted that a larger force was necessary to ensure that South Africa did not interfere with independence proceedings. Against their objections UNTAG's force levels were reduced from the proposed 7,500 to three battalions of 4,650 troops. This slashed projected expenses by nearly three hundred million dollars, but the Security Council did not approve the revised budget until 1 March 1989. The inevitable delay in UNTAG's full deployment ensured there were insufficient personnel prepared to monitor the movement of PLAN and the SADF or their confinement to bases on 1 April, when the permanent cessation in hostilities was to take effect.  Secretary-General de Cuéllar urged restraint in the interim on both sides to avoid jeopardising the de facto ceasefire maintained since August 1988 or the 1 April implementation schedule. Nevertheless, PLAN took advantage of the political uncertainty in the weeks following the UNTAG budget debate to begin moving its forces in Angola closer to the border.
  Since the early 1980s PLAN had consistently stated its intention to establish camps inside South West Africa during any future political transition, a notion rejected with equal consistency by the South African government. Compounding this fact was that PLAN insurgents also identified themselves as refugees without making any distinction between their civilian or military background, and the UN had explicitly invited refugees to return home. Indeed, PLAN did not possess many regular standing units and by the late 1980s many of its personnel followed cyclical patterns of fighting as insurgents before returning to refugee camps as civilians. On 31 March, Pik Botha complained to the JMMC that PLAN troops had advanced south of the 16th parallel and were massing less than eight kilometres from the border. He promptly intercepted UN Special Representative Martti Ahtisaari and UNTAG commander Dewan Prem Chand that evening and gave them the same information. On the morning of 1 April, the first PLAN cadres crossed into Ovamboland, unhindered by UNTAG, which had failed to monitor their activity in Angola due to the delays in its deployment. Ahtisaari immediately contacted SWAPO, ordering it to rein in PLAN, to little avail. The South African foreign ministry also contacted the Secretary-General, who in turn relayed the same message to SWAPO officials in New York.
  At the end of the day, with no signs of the PLAN advance abating, Ahtisaari lifted all restrictions confining the SADF to its bases. Local police mobilised and fought off the invaders in a delaying action until regular SADF forces were able to deploy with six battalions. After the first two days the insurgents lost their offensive initiative, and the combined South African forces drove PLAN back across the border in a counteroffensive codenamed Operation Merlyn. Between 1 April – 9 April 273 PLAN insurgents were killed in the fighting. The SADF and police suffered 23 dead. On 8 April, the JMMC had issued the Mount Etjo Declaration, which reiterated that the Tripartite Accord was still in effect and that South Africa, Angola, and Cu
