After taking several positions around the town, the TPDF advanced into Mpigi on 28 March 1979, encountering no further position as the garrison had fled. Historian Richard J. Reid argued that the confrontation at Mpigi constituted "Amin's last stand". The Tanzanians consequently set up artillery to shell Kampala as well as the crucial airport at Entebbe. In the following days, the TPDF defeated further Ugandan and Libyan contingents and gradually secured Mpigi's surroundings. This allowed the Tanzanians to capture Entebbe on 7 April, followed by Kampala on 11 April 1979.
