In early 1983, to eliminate rural support for Museveni's guerrillas the area of Luwero District, north of Kampala, was targeted for a massive population removal affecting almost 750,000 people. These artificially created refugees were packed into several internment camps subject to military control, which in reality meant military abuse. Civilians outside the camps, in what came to be known as the "Luwero Triangle," were presumed to be guerrillas or guerilla sympathizers and were treated accordingly. The farms of this highly productive agricultural area were looted—roofs, doors, and even door frames were stolen by UNLA troops. Civilian loss of life was extensive, as evidenced some years later by piles of human skulls in bush clearings and alongside rural roads.
