When Amin's regime finally collapsed and Kampala fell to the Tanzanians, Maliyamungu fled with his family across the border to Zaire. He took a substantial amount of his wealth with him, and intended to become a businessman. Maliyamungu subsequently became involved in the pro-Amin rebellion in the West Nile sub-region during the Ugandan Bush War. Having gathered a band of fighters, he invaded the West Nile region from Zaire in coordination with other Amin loyalists. He later moved to Sudan where he died of poisoning in February 1984.
