When the Uganda–Tanzania War broke out under unclear circumstances in October 1978, the Uganda Army soon began to encounter serious difficulties. The Ugandan Invasion of Kagera was repelled by November 1978, as the Tanzania People's Defence Force (TPDF) launched a large-scale counter-offensive. After retaking Kagera, the Tanzanians advanced into Uganda. At the time, Radio Tanzania falsely claimed that Amin had dismissed Maliyamungu and put him under house arrest.
