[5] Under Amin's rule, Lumago became Minister of Industry and Power before—at the rank of colonel—being appointed Uganda's High Commissioner to Lesotho in 1975.

[7] Lumago and Colonel Gad Wilson Toko, who was in Nairobi for non-military reasons, managed to telephone Brigadier Isaac Maliyamungu after failing to reach Uganda Army Chief of Staff Mustafa Adrisi.

Maliyamungu, who was reportedly drunk at a night club, dismissed the warning and told both men that since they were acting in civilian capacity they should not concern themselves with military matters.

[8] The Israelis subsequently launched Operation Entebbe, rescuing the hostages and destroying a significant portion of the Uganda Army Air Force.

[11] In early 1978, a political rivalry between Adrisi and President Idi Amin gradually escalated until the former was injured in a suspicious car accident.

[12] Afterwards, on 8 May he was dismissed as Chief of Staff and Minister of State for Defence and relegated to inspecting the equipment of the army's mechanised regiments.

He accepted, joined Okello's government, and consequently began to fight against another rebel movement, the National Resistance Army (NRA) of Yoweri Museveni.

Meanwhile, FUNA was accused of gross indiscipline, reportedly raping and murdering civilians in the capital and other areas, though Lumago denied these charges.

Despite appeals by Ugandan government officials to peacefully return to Uganda, Lumago initially refrained from laying down his weapons out of fears of reprisals due to his long opposition against Museveni.
