 In 1983, the Obote government launched Operation Bonanza, an extensive military expedition of UNLA forces that alone claimed tens of thousands of lives and displaced a significant portion of the population.The blame for the massacres was placed on the people of northern Uganda for supporting the actions of the NRA, which increased the existing regional tensions in the country.The UNLA also defeated the UFM in 1983, destroying its main camps during a coordinated counter-insurgency operation.
