Analysis of the military campaign waged in Southern Angola in 1987-88 as well as the lessons learned from this exchange. Document indicates that FAPLA failed to learn from its mistakes, while UNITA adapted much more effectively to the combat environment it faced in Angola. Although FAPLA managed to hold on to Cuito Cuanavale, its large losses led to a Cuban build-up in Southern Angola, which challenged the existing military balance in the region. This provided new impetus to peace negotiations and resulted in the December 1988 Accords among South Africa, Angola and Cuba.
