On this day in 1980, an estimated 500 former soldiers of Idi Amin's Uganda Army crossed into Uganda from exile and attacked Koboko in West Nile, marking the opening of the armed conflict that would become known as the Ugandan Bush War, Luwero War or Liberation War.
The fighters, many of whom had fled into Sudan and Zaire after Amin was overthrown in April 1979, caught the Uganda National Liberation Army (UNLA) garrison off guard and briefly overran Koboko. The insurgents subsequently moved into other parts of West Nile, taking places including Bondo, Arua, Moyo, Maracha and Oraba before eventually retreating across the border with supplies.
The attack came at a particularly fragile moment for Uganda. Amin had seized power from Milton Obote in a 1971 coup and ruled through a military dictatorship until his overthrow by Tanzanian forces and Ugandan exiles in 1979.
The fall of Amin did not end the violence. His former soldiers regrouped outside the country, while the new UNLA struggled to establish authority across a state emerging from years of military rule and conflict.

Milton Obote returned to power after the December 1980 general elections, but opposition groups disputed the result. The political crisis soon developed into a wider insurgency.
While the West Nile fighting had already opened an armed front, Yoweri Museveni and his supporters launched the rebellion that became the National Resistance Army (NRA) on February 6, 1981, with an attack on Kabamba Military Barracks.
That distinction is important in Uganda's history. October 6 is associated with the beginning of the wider civil war, while February 6, commemorated as Tarehe Sita, is officially recognised as the beginning of the NRA's liberation struggle.
The war that followed pitted Obote's government and the UNLA against several armed groups, with Museveni's NRA eventually becoming the most consequential. Fighting spread through central, western and southern Uganda, while government counterinsurgency operations brought severe consequences for civilians, particularly in areas suspected of supporting the rebels. Academic histories of the NRA conflict generally date its central phase from 1981 to 1986.
The political crisis deepened in July 1985 when Obote was overthrown by a military coup led by officers of the UNLA. General Tito Okello became president and attempted to negotiate with the NRA. Peace talks were held in Nairobi, producing an agreement and ceasefire, but the arrangement collapsed as fighting resumed.

By then, the balance of the war was shifting decisively. The NRA launched coordinated offensives in central and western Uganda in the second half of 1985, capturing important garrison towns including Masaka and Mbarara. Its ranks expanded rapidly as new recruits joined and government soldiers defected.
The collapse of the Okello government followed within months. The NRA captured Kampala on January 26, 1986, effectively ending the six-year conflict. Museveni was sworn in as president three days later, on January 29, while Okello fled into exile.
The UNLA did not disappear immediately. Its remnants attempted to regroup in northern Uganda, but the army eventually disintegrated, while Obote and other senior figures went into exile. The NRA became Uganda's new regular army as Museveni's National Resistance Movement formed the new government.
The end of the Bush War did not, however, bring an end to armed rebellion in Uganda. Several anti-NRA groups remained active after 1986, particularly in northern Uganda, laying the foundations for subsequent conflicts that would occupy the country for years.
October 6, 1980 therefore occupies a complicated place in Uganda's history. It predates the NRA's Tarehe Sita attack by four months, but it marks the moment when the post-Amin crisis developed into another sustained armed conflict. What began with the attack on Koboko would ultimately become a six-year war that ended with the capture of Kampala and the establishment of a new political order in January 1986.
