Ghana, 1967 — military coup attempt

Ghana (GHA)West Africa, AfricaApril 17, 1967

Event Summary

On 17 April 1967 a group of junior officers of the Ghana Armed Forces attempted a coup, code named Operation Guitar Boy, against the ruling National Liberation Council, the military and police junta that had overthrown Kwame Nkrumah in February 1966. The attempt was led by Lieutenants Samuel Arthur and Moses Yeboah with 2nd Lieutenant Osei Poku and some 120 soldiers of the 2nd Reconnaissance Regiment. Although it failed, the coup resulted in the assassination of Lieutenant General Emmanuel Kwasi Kotoka, a key member of the ruling council, who was shot and killed by Lieutenant Yeboah at the Accra airport.

The plotters briefly seized Broadcasting House, where, in a bizarre touch, they played the Nigerian hit song Guitar Boy that gave the operation its name. The rising was quickly suppressed, the NLC head of state Joseph Ankrah survived, and Arthur and Yeboah were tried and executed in May 1967.

Editorial Note

Date match, well documented as Operation Guitar Boy. Dataset codes leader remained in office, accurate for NLC chairman Ankrah though council member Kotoka was killed. First Ghana record in the dataset run; the successful 1966 anti-Nkrumah coup is a separate base event.
