During the first year of the war, the RUF took control of large swathes of territory in eastern and southern Sierra Leone, which were rich in alluvial diamonds. The government's ineffective response to the RUF, and the disruption in government diamond production, precipitated a military "coup d'état" in April 1992 by the National Provisional Ruling Council (NPRC). By the end of 1993, the Sierra Leone Army (SLA) had succeeded in pushing the RUF rebels back to the Liberian border, but the RUF recovered and fighting continued. In March 1995, Executive Outcomes (EO), a South Africa-based private military company, was hired to repel the RUF. Sierra Leone installed an elected civilian government in March 1996, and the retreating RUF signed the Abidjan Peace Accord. Under UN pressure, the government terminated its contract with EO before the accord could be implemented, and hostilities recommenced.
