Military coup and ousting of Tshombe 5 Commando became highly efficient in working with the ANC troops and they cleared eastern Congo of Simba rebels. They almost captured
Che Guevara in his camp, forcing him to escape to
Tanzania, but these victories came at a political cost. On 13 October 1965, Congolese President
Joseph Kasa-Vubu relieved Prime Minister Tshombe of his duties and replaced him with
Évariste Kimba, considering Tshombe too ambitious and too unpopular both in the country and in neighboring African states.
Mobutu shortly thereafter removed both President Kasavubu and Prime Minister Kimba in a coup, appointing himself President. Tshombe had been a friend of, and protector to, 5 and
6 Commando, so his ousting immediately caused uncertainty and insecurity within 5 Commando. Jerry Puren left the Congo with Tshombe for exile in Belgium. Mike Hoare and Alistair Wicks did not renew their contracts and left the Congo. John Peters, then commanding officer of 5 Commando, continued to pledge his—and the unit's—loyalty to the government and continued operations in southern Congo.
Mercenary revolt Jerry Puren, once in Belgium, was informed of a plan to reinstall Tshombe as Prime Minister. The Baka Regiment of the ANC, together with the mercenary commandos led by
Jean Schramme and by
Bob Denard, had committed to support the plan. Puren refused to take part in the counter-coup and Mike Hoare, Alistair Wicks, John Peters and Hugh van Oppen (Peters and van Oppen were still serving members of 5 Commando) were approached to support the revolt but all refused. On 23 July, the Baka Regiment and 11, 12, 13 and 14 Commandos revolted to support the exiled Tshombe, killing the commander of the ANC and taking control of the radio station in Stanleyville. 6 Commando, led by
Bob Denard, opposed the uprising and notified the government; they called for support to put down the uprising. A stalemate ensued in Stanleyville until September 1966, when Denard attacked the
Katanga units in the city. 5 Commando re-deployed from southern Congo to support 6 Commando to cover any Katanga escape routes from the city. A truce was negotiated and those Katanga troops who were not killed were given amnesty, while officers were transported to prisons in
Elisabethville. The rebellion had failed and Mobutu remained secure as president. The failed rebellion did, however, reinforce perceptions that 5 and 6 Commando were loyal to Mobutu. After this failed revolt, Puren (still in Belgium) started his own plan to reinstall Tshombe, selecting Jean Schramme of 10 Commando to lead the second revolt. After much planning, including Denard in the planning, Schramme launched surprise attacks on Stanleyville,
Bukavu and
Kindu. Stanleyville and Bukavu were taken with little resistance, but the mercenaries faced stronger resistance in Kindu. ANC forces recovered Stanleyville, executing several mercenaries, and Schramme withdrew from the city to establish a stronghold in Bukavu. Mobutu issued an ultimatum, ordering Schramme to evacuate Bukavu within ten days. The ANC attacked when the ultimatum expired; on 5 November 1966, Schramme, together with 150 mercenaries, 800 Katanga soldiers and 1,500 women and children fled across the Rwandan border and were disarmed and interned by the
Rwandan military at
Shangugu. The second mercenary revolt had also collapsed. Elsewhere in other skirmishes, many mercenaries were massacred and surviving European mercenaries were evacuated by the
Red Cross.
Disbandment Mobutu ordered all recruitment for 5 Commando to cease in March 1967; the unit was disbanded in April on Mobutu's order. He likely did so for three reasons: to avoid the expense of paying the mercenaries, to forestall any attempts by Tshombe to use the unit in a further coup attempt, and to avoid the potential embarrassment of employing white mercenaries when the Congo was due to host an upcoming
Organisation of African Unity annual conference in September. ==In popular culture==
