The Battle of Karuma Falls was one of the last battles in the Uganda–Tanzania War, fought between Tanzania and Uganda Army troops loyal to Idi Amin on 17 May 1979. Soldiers of the Tanzania People's Defence Force attacked Ugandan forces at the bridge over the Nile River at Karuma Falls. Tanzania's 205th Brigade was tasked with advancing from Masindi to Gulu, taking a route which passed over the Karuma Falls Bridge. The brigade assaulted the crossing on the morning of 17 May with tanks and artillery and one of its battalions ran over the bridge to attack the Ugandan positions. The Ugandans destroyed a TPDF tank, delaying the Tanzanians long enough to board buses and retreat to Gulu. The Tanzanians secured Karuma Falls before capturing Gulu several days later.
Background
In 1971 Idi Amin launched a military coup that overthrew the President of Uganda, Milton Obote, precipitating a deterioration of relations with the neighbouring state of Tanzania. Amin installed himself as President and ruled the country under a repressive dictatorship. In October 1978 Amin launched an invasion of Tanzania. Tanzania halted the assault, mobilised anti-Amin militant groups, and launched a counter-offensive.
In a matter of months, the Tanzania People's Defence Force (TPDF) and its Ugandan rebel allies (unified under the umbrella organisation, Uganda National Liberation Front (UNLF)) defeated the Uganda Army in a number of battles, and occupied Kampala, Uganda's capital, on 11 April 1979. With his military disintegrating, Amin's rule collapsed. Having escaped from Kampala, he traveled to a succession of cities in eastern and northern Uganda, urging his remaining forces "to go back and fight the enemy who had invaded our country", even as he prepared to flee into exile. Most Uganda Army units opted to surrender, desert or defect to the Tanzanian-led forces, but some decided to continue to fight for Amin's defunct regime. The Tanzanians and the UNLF allies continued their advance to secure eastern and northern Uganda.
Prelude
The TPDF's 205th Brigade, which had occupied the town of Masindi, was ordered to capture Gulu. The TPDF's two brigade-strong "Task Force", was instructed to secure the West Nile District. Both paths required the TPDF to take the Kampala–Gulu Road, which passed over the Nile River via the bridge at Karuma Falls. It was decided that the 205th Brigade, commanded by Brigadier Muhiddin Kimario, would advance first and secure the crossing. The bridge, which lay south of Gulu, was one of three such crossings over the Nile in Uganda, and it had been frequently used by Amin's agents to dump the bodies of executed dissidents into the river. Area residents also reported that bodies of Ugandan soldiers who had been killed in combat were disposed of there. Anti-Amin militants of Yoweri Museveni's Front for National Salvation were originally supposed to seize the location before Kampala fell, but moved too slowly. A group of Uganda Army soldiers maintained a roadblock at the Karuma Falls Bridge, where they harassed and robbed passing civilians.
The 205th Brigade's advance was delayed due to a gasoline shortage, and by the time the requisite fuel had arrived in Masindi, the unit was two days behind schedule. Kimario had his men move faster to make up for the lost time so as to not interfere with the plans of the Task Force, which was following them. The evening before the brigade was to cross the river, a reconnaissance team spotted a company of Uganda Army soldiers at the bridge. Since the rough terrain in the area made crossing elsewhere difficult, Kimario decided that a direct attack on the bridge would be necessary.
Battle
On the morning of 17 May 1979 the 205th Brigade advanced towards the south end of the Karuma Falls Bridge. The Tanzanians saw a large group of Ugandan soldiers gathered to the north of the bridge near a blind corner of the Gulu road. The 205th Brigade conducted a 10-minute artillery barrage of the northern bank of the river. The Ugandans did not respond, leading Kimario to assume that they had fled. However, when the Tanzanians began advancing, the Ugandan troops subjected them to small-arms fire. Three Tanzanian tanks moved to the front of the brigade's column, and the Ugandans reacted by initiating a mortar barrage.
