In October 1999, the United Nations agreed to send peacekeepers to help restore order and disarm the rebels. The first of the 6,000-member force began arriving in December, and the UN Security Council voted in February 2000 to increase the force to 11,000, and later to 13,000. The UN peacekeeping forces were made up mainly of soldiers from the British special forces, India, Bangladesh and Pakistan. The African Union special forces sent to Sierra Leone to assist the government in fighting the rebels were made up mainly of soldiers from Nigeria, Guinea, Ghana, Kenya, Mali, Zambia and The Gambia. The international forces, led by the British troops, launched a number of successful military operations to repel the RUF rebels and retake many of the areas of the country that were under the rebel control. The rebel lines of communication were severely disrupted and many senior rebel leaders were captured or fled the country, including the RUF leader Foday Sankoh, who was captured.
