In November 1978, troops loyal to Adrisi mutinied. Amin sent troops against the mutineers, some of whom had fled across the Tanzanian border. Fighting consequently broke out along the Ugandan–Tanzanian border, and the Uganda Army launched an invasion of Tanzanian territory under unclear circumstances. According to several experts and politicians, Amin directly ordered the invasion in an attempt to distract the Ugandan military and public from the crisis at home. Other accounts suggest, however, that Amin had lost control of parts of the Uganda Army. Accordingly, the invading troops acted without his orders, and Amin sanctioned the invasion "post facto" to save face. In any case, Amin accused Tanzanian President Julius Nyerere of initiating the war against Uganda after the hostilities had erupted, and proclaimed the annexation of a section of Kagera when the Ugandan invasion initially proved to be successful.
