Obote delayed appointing a successor to Oyite Ojok for as long as possible. In the end, he appointed a Lango to the post and attempted to counter the objection of Acholi officers by spying on them, reviving his old paramilitary counterweight, the mostly Langi Special Force Units, and thus repeating some of the actions that led to his overthrow by Amin. As if determined to replay the January 1971 events, Obote once again left the capital after giving orders for the arrest of a leading Acholi commander, Brigadier (later Lieutenant General) Bazilio Olara-Okello, who mobilized troops and entered Kampala on 27 July 1985. Obote, together with a large entourage, fled the country for Zambia. This time, unlike the last, Obote allegedly took much of the national treasury with him.
