The Uganda People's Defence Force (UPDF), previously known as the National Resistance Army, is the armed forces of Uganda. From 2007 to 2011, the International Institute for Strategic Studies estimated the UPDF had a total strength of 40,000–45,000 and consisted of land forces and an air wing. Recruitment to the forces is done annually.
The Tanzania People’s Defence Force (TPDF) is the military force of the United Republic of Tanzania. It was established in September 1964, following a mutiny by the former colonial military force, the Tanganyika Rifles. From its inception, it was ingrained in the troops of the new TPDF that they were a people's force under civilian control. Unlike some of its neighbouring countries, Tanzania has never suffered a coup d'état or civil war.
The Uganda–Tanzania War, known in Tanzania as the Kagera War and in Uganda as the 1979 Liberation War, was fought between Uganda and Tanzania from October 1978 until June 1979 and led to the overthrow of Ugandan President Idi Amin. The war was preceded by a deterioration of relations between Uganda and Tanzania following Amin's 1971 overthrow of President Milton Obote, who was close to the President of Tanzania, Julius Nyerere. Over the following years, Amin's regime was destabilised by violent purges, economic problems, and dissatisfaction in the Uganda Army.
Kikosi Maalum, also known as the Special Battalion or the grand coalition, was a militia of Ugandan exiles formed in Tanzania to fight against the regime of Idi Amin. The unit was founded by and loyal to former Ugandan President Milton Obote, and served as his de facto private army. It was commanded by former army officers David Oyite-Ojok, and Tito Okello. Kikosi Maalum took part in the Uganda–Tanzania War, fighting alongside the Tanzanian military against Amin's forces. In course of this conflict, the militia was nominally unified with other Ugandan rebel groups, forming the Uganda National Liberation Army (UNLA) in 1979. After the fall of Amin's regime and Obote's return to power, Kikosi Maalum became the core of Uganda's new national army.
The Battle of Lukaya was a battle of the Uganda–Tanzania War. It was fought between 10 and 11 March 1979 around Lukaya, Uganda, between Tanzanian forces and Ugandan government forces. After briefly occupying the town, Tanzanian troops and Ugandan rebels retreated under artillery fire. The Tanzanians subsequently launched a counterattack, retaking Lukaya and killing hundreds of Libyans and Ugandans.
The Battle of Entebbe was a battle of the Uganda–Tanzania War that took place on 7 April 1979 on the Entebbe peninsula in Uganda between Tanzanian units and Ugandan and Libyan units. The Tanzanians occupied the area, killed hundreds of Libyans, and ended the Libyan airlift in support of the Ugandan government.
The Battle of Sembabule was a battle of the Uganda–Tanzania War that took place from March to 5/6 April 1979 in the town of Sembabule, Uganda. Tanzania had repulsed a Ugandan invasion in late 1978, and in early 1979 the Tanzania People's Defence Force (TPDF) crossed into southern Uganda. The Tanzanians decided shortly thereafter to attack the Ugandan capital, Kampala, and the 205th Brigade was detailed in early March to be sent north from Masaka and then west of the city. Ugandan President Idi Amin declared over radio that his forces were about to surround the TPDF, prompting Tanzanian commanders to dispatch the 205th Brigade to deal with the Uganda Army's Tiger Regiment in Mubende. While moving north, the 205th Brigade encountered the Tiger Regiment at Sembabule, beginning a three-week-long battle. The Tiger Regiment effectively resisted the Tanzanians for some time, prompting a change in command of the 205th Brigade and alterations in its tactics, bringing about the eventual fall of Sembabule to the Tanzanians on 5 or 6 April. The Battle of Sembabule was the longest battle of the war.
The Battle of Tororo was a battle of the Uganda–Tanzania War that took place from 2 to 4 March 1979 at Tororo, Uganda and its surroundings. It was fought between Ugandan rebels loyal to Milton Obote and Uganda Army units loyal to President Idi Amin. In an attempt to destabilise Amin's rule and capture weapons for an insurrection, a group of guerrillas launched a raid from Kenya against Tororo, whose garrison partially mutinied and joined them after a short fight. Loyalist Ugandan military forces, most importantly its air force, launched a large-scale counter-attack and completely defeated the rebels after heavy fighting.
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.
During the Uganda–Tanzania War, the Battle of Bondo was fought on 27 May 1979 near the town of Bondo, Uganda, between Tanzanian forces and Ugandan troops loyal to Idi Amin. A band of Uganda Army soldiers opened fire on the Tanzanian Minziro Brigade as it advanced towards Arua, before fleeing in the face of a Tanzanian charge. Several Tanzanians were killed and wounded by their own artillery. It was the last battle of the war. Arua fell without resistance shortly thereafter.
The Battle of Mutukula took place from 21 to 22 January 1979 near and in the town of Mutukula, Uganda, during the Uganda–Tanzania War. After repulsing a Ugandan invasion of the Kagera Salient in 1978, Tanzanian commanders feared that Ugandan forces stationed upon the high ground in Mutukula, a town located along the Tanzania–Uganda border, still posed a threat to their territory. On the night of 21 January 1979 the Tanzanian 208th Brigade crossed the border and surrounded the town. The following morning it attacked, and the Ugandan garrison—including the Gondo and Suicide Battalions—fled. Afterwards the Tanzanians razed the locale in revenge for the damage wrought by the Ugandans in Kagera.
The Uganda–Tanzania War of 1978–79 included an air campaign, as the air forces of Uganda and Tanzania battled for air superiority and launched bombing raids. In general, the conflict was focused on air-to-ground attacks and ground-based anti-aircraft fire; only one dogfight is known to have occurred.
The Battle of Simba Hills or Battle of Kakuuto was a conflict of the Uganda–Tanzania War that took place over several days in mid-February 1979 around the Simba Hills in southern Uganda, near the town of Kakuuto. Tanzanian troops advanced over the Ugandan border and assaulted the Ugandans' positions, forcing them to retreat.
Andrew Joet Mukooza was a Ugandan military officer who served as the last head of the Uganda Army Air Force before its destruction during the Uganda–Tanzania War of 1978–79. Born in eastern Uganda, Mukooza joined the air force during the presidency of Milton Obote. In 1971, army commander Idi Amin assumed power in Uganda. Mukooza stayed firmly loyal to Amin's regime, and consequently rose in the ranks. He possibly helped Amin to defeat a coup attempt in 1977, drawing the ire of Uganda's opposition. When the Uganda–Tanzania War broke out, Mukooza initially flew missions as fighter pilot and became head of the Uganda Army Air Force when the latter began to disintegrate amid combat losses, defections, and desertions. Following the defeat of Amin, Mukooza surrendered to the new Tanzanian-backed government of Uganda, but was murdered under uncertain circumstances.
The Uganda Army, also known as Uganda Armed Forces, served as the national armed forces of Uganda during the dictatorship of Idi Amin (1971–1979). It mostly collapsed during the Uganda–Tanzania War, but remnants continued to operate in exile from 1979. These pro-Amin rebel forces continued to be called the "Uganda Army" and maintained a semblance of cohesion until 1980, when they fully fractured into rival factions.
Godwin Sule was a high-ranking Sudanese-born Ugandan military officer who held important commands in the Uganda Army during the dictatorship of President Idi Amin. A native of southern Sudan, he fought as a rebel in the First Sudanese Civil War before migrating to Uganda. There he rose to command the Malire Battalion and later the Paratroopers Military School. Regarded as one of the most talented soldiers in the Uganda Army during Amin's rule, Sule was tasked with leading the last major Ugandan counter-offensive during the Uganda–Tanzania War of 1978–79. This operation culminated in the Battle of Lukaya of 10–11 March 1979, during which Sule was killed under unclear and disputed circumstances. His death resulted in the collapse of the Ugandan offensive, contributing to the eventual overthrow of Amin's regime.
Foreign support played an important role for Uganda during the Uganda–Tanzania War of 1978–1979. Before this conflict, the Second Republic of Uganda under President Idi Amin had generally strained international relations. Accordingly, only a few states as well as non-state allies provided Uganda with substantial military support during the war, most importantly Libya under Muammar Gaddafi and the Palestine Liberation Organisation. The intervention of these two parties was regarded as crucial for Amin's ability to stay in power during the later stages of the war, even though they did not prevent Uganda's eventual defeat. However, there were many claims about other states and groups in Africa, the Arab world, Europe, and Asia covertly supplying Amin with materiel, soldiers, and money, although most of these remain unverifiable.
Taban Lupayi, often just called Taban, was a high-ranking Sudanese-born Ugandan military officer during the dictatorship of Idi Amin. He rose to commander of the Marine Regiment and deputy chief of staff of the Uganda Army following the 1971 Ugandan coup d'état, and became a member of Amin's inner circle. Taban deserted his post during the Uganda–Tanzania War in 1979, fleeing to southern Sudan.
Yorokamu Tizihwayo, also known as Y. Tiziriwayho and Yerukamu, was a Ugandan military officer. He served as a high-ranking commander during Idi Amin's rule as Ugandan President, first as the head of the 2nd Paratrooper Battalion and later for the Western Brigade. In the Uganda–Tanzania War (1978–1979), Tizihwayo led the Uganda Army troops which opposed the Tanzania People's Defence Force's advance into western Uganda. Despite being regarded as a talented soldier and considered one of the Tanzanians' more dangerous opponents during the war, he was eventually arrested and executed on alleged treason charges by Amin's State Research Bureau.
Bernard Rwehururu was a Ugandan military officer and author. He served in various Ugandan militaries from 1965 until 2013, including under the governments of Milton Obote, Idi Amin, Tito Okello, and Yoweri Museveni.
