In 1999, the battle lines achieved a rough stalemate. At the same time, the character of the RCD changed as former supporters of
Mobutu Sese Seko and dissidents from outside the country began to join. Once it became clear that Kabila would not be overthrown, fracture lines began to appear in the organization, and Rwanda and Uganda began to struggle over who would control the RCD, and the RCD's access to natural resources such as diamonds and other valuable minerals. Tensions came into the open in May 1999 when Wamba dia Wamba left to establish a group in the town of
Kisangani with the support of Uganda, apparently over a disagreement with former Mobutu supporter
Lunda Bululu. His organization eventually became known as the
RCD-Kisangani (RCD-K), or sometimes RCD-Wamba. Dr. Emile Ilunga took over leadership of the older faction, often referred to as
RCD-Goma to distinguish it from the group led by Wamba. Rwanda became the primary supporter of the RCD Goma, thereby transferring the tension between Uganda and Rwanda into their proxy rebel forces. Things came to a head when the two RCDs and their patrons met in battle in
Kisangani, the capital of
Orientale Province, where the Ugandan army was defeated. Battles in Kisangani occurred in 1999 and 2000 (the so-called '
Six-Day War'). Wamba retreated to
Bunia, where he faced widespread discontent and revolt within his own organization as the
Ituri conflict began.
Mbusa Nyamwisi rejected Wamba's leadership and took control of northern
North Kivu and
Ituri with the support of some Ugandan generals. Nyamwisi renamed the RCD-K the RCD-Mouvement de Libération (RCD-Movement for Liberation, RCD-ML). The Rwandan-supported RCD retained control of southern North Kivu,
South Kivu,
Maniema, north
Katanga, eastern
Kasai, and
Kisangani. In 2000,
Adolphe Onusumba replaced Ilunga as head of the Goma-based RCD. The new RCD leadership's authority was demonstrated after the Kinshasa offensive in November 2000 was defeated at
Pweto. This also illustrated that it was unlikely that Kinshasa would be able to retake eastern Congo militarily. Despite attempts to win the hearts and minds of the Kivutians, the continued
human rights abuses and bureaucratic ineptitude ruined these efforts. The Rwandan-backed RCD continued to be the primary Tutsi force aligned with Rwanda and Burundi. Rwanda appeared to decide that maintaining a sphere of influence in the Kivus through proxy forces is in its best interests. This is similar to the policy that Uganda had decided upon several years earlier. ==Other RCD factions==
